  • RIP

  • RIP, how fascinating!!

  • We only technically outlived Neil Armstrong....he outlived us all.

  • RIP Neil Armstrong! Thank you for your inspiration!

  • RIP!

  • Tank you neil

  • If ur country did it ... Why it didnt do it again in this long time from the first time ?!

  • R.I.P

  • All you dont want to show about the moon

  • R.I.P Neil. . Thanks Awesome Job

  • R. I. P. ..NEIL. It's cool how many people have been on the moon after Neil.

  • Thank you Neil.

  • @abedkadah there were 6 manned moon landings you fool. And probably for financial reasons and there is nothing more to gain.

  • There are very few more amazing than Neil.

  • R.I.P,Neil.

  • @markbob917 your point of view makes sense !

  • He was such a great insperation to me! I love what he done, he showed us that the impossible can be done! R.I.P Neil Armstrong you did a great job!

  • @abedkadah go take more pictures of yourself and post them, seems that's all you're good for. Respect those who have touched millions. TOOL!

  • Спасибо тебе, Нил.

  • Rest in peace. 🚀🇺🇸

  • Why are the shadows going two different directions.just sayin

  • One of mans greatest achievements

  • doegie 5y ago

    @gadgetarms215 if you're a conspiracy addict, there's a mythbuster-episode on discovery channel about the shadows... The conspiracy theory got "busted"...

  • RIP NEIL. .

  • R.I.P. to a true hero

  • First off rip neil.i never said anything about a conspiracy.i just said look at the shadows neils goes straight up.and the flag pole or what ever it is on the right goes on an angle to the left.

  • Great picture! RIP Neil

  • Goodbye Neil- We love u~ from Mongolia

  • riposa sognatore. ty

  • May your soul rest in peace neil!

  • It's saddening beyond words to lose one of mankind's most remarkable individuals. My dream was to meet him some day, but he is in a better place now. Farewell, Neil Armstrong

  • His soul is venturing space now..

  • Goodbye Neil and thank you!

  • R.I.P.

  • adrdaw 5y ago

    Per his family..."For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment, and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink."

  • RIP Neil Armstrong

  • NASA can commission me to produce a commemorative portrait and produce a limited edition print run exclusive to NASA.... Contact me for details

  • RIP Neil Armstrong...

  • Mr Neil Armstrong, RIP! You will be remembered.

    Buen astronauta pero no muy buen fotografo. :s

  • RIP the first man to walk the moon.

  • R.I.P. 🚀🙏

  • Armstrong ñ passou pela vida... Fez e deixou sua história!

  • S.I.p. thank you neil for giving us a beautiful historical event ....

  • 1ndo_ 5y ago

    Why doesn't NASA put him on the moon for he's death @nasagoddard

  • One of the coolest under pressure guys I've ever known about.

  • R.I.P

  • @jones_a Has no one informed you that the stars are blinded out by the surface brightness of the moon? I'm assuming you are suggesting that the moon landing was faked. Sureeee. I have some extra tin foil over here if you need a new hat.

  • The first most big fake of the history.just one question:where are the originals records,Mister Nasa?

  • tila_8 5y ago

    O homem que representou - O Grande Passo para Humanidade.

  • they are saying its Apollo fake 11

  • For all you idiots out there who think the Apollo 11 landing was fake, I ask you to please go to your nearest airport buy and buy a one way ticket out of OUR beautiful country!! I will honor Mr. Armstrong tonight by sending a thank you to him while gazing at the MOON. RIP

  • Sad when people come to a science CHANNEL and say they lie with nothing but words to back up what they say. Knowledge is for everyone. Please study. You are embarrassing yourself. RIP NEIL ARMSTRONG. And yes Neil is not the only person that has walk on the moon.

  • idk about everyone eles but i loveee science and when i found out that he died i was almost in tears. rip neil armstrong

  • Anyone who says Apollo 11 was a fake defiles the memory of an amazing man and an amazing achievement. He was a humble hero that deserves nothing but the utmost respect and will be sadly missed. RIP Neil A. Armstrong.

  • Great man! Who had a great moment! Go to heaven Neil! Go

  • True American Hero!

  • Niall Armstrong, may you rest in peace on the sea of tranquility

  • @sisiazura @blackbara 12 people have walk on the Moon. The last person was Harrison Schmitt on Apollo 17 on December 1972. If you are talking about a video in the old days that said we did not walk on the moon because the flag could not wave in space. I saw it and started laughing. That was not a science video because the Kenitic energy alone would put the flag into motion and there is more. Science is Real. NASA is Real. You can learn more about what NASA is doing at NASA Desert Rats. It is an off world vehicle for people to get around. Get the Mars Clock App for the difference in time from Earth also. Time slow down the faster you go. That’s real science. NASA is Real. Hope this helps. RIP NEIL ARMSTRONG

  • RIP Neil Armstrong

  • anjx 5y ago

    Farewell Mr. Armstrong🚀

  • Sad when people start a memorial on an instagram channel. And surface brightness would never ever blind out the stars from the sky without blinding out the camera at least so fuck you where are the stars

  • RIP Neil Armstrong.....

  • Rip armstrong

  • Thank you, N . A. , for the most exciting TV - show ever. R I P. <3

  • @mellon_e_rivera For Malachi....

  • @jones_a , shut the fuck up you disrespectful piece of shit. No one appreciates you're ridiculously petty comment at this time. This instagram is one of NASA's forms, not been made just for the reason an icon of the 20th century has past. So keep you're unwanted comments to yourself! RIP Armstrong...


  • Flip off jerk. My Grandfathers name is on the moon !!!! Looser. How do you think the flag got there? R.I.P. Armstrong

  • My grandfather along with Grumman's built the Lunar earth Module (Lem)

  • Lunar Explorer***

  • rupley 5y ago

    @jones_a Get a life. You know nothing about optics, terrestrial or otherwise. Take your negativity and go play on Facebook with the rest of the trolls.

  • Ha you think im a troll

    Who ever said the moon landing was fake just stfu and honor the mans death

  • vocalt 5y ago

    RIP Neil Armstrong

  • He will be greatly missed, but at least he lived a good life and was the first man on the moon. Rest in peace Neil Armstrong.

  • Lets blow up the moon :•d

  • riposa uomo dei sogni

  • RIP Neil

  • :(

  • So long Neil RIP

  • R.I.P Neil......

  • God Speed Neil 🎇👍👣👣👣

  • @nasagoddard thank you mr. Armstrong god bless

  • Rest In Peace.

  • Neil Armstrong deserves a State Funeral.

  • 🙏

  • Neil Armstrong is my favorite person in the world, and unless you watched them fake it (which they didn't) then you can't say anything so don't even bother

  • If the Russians had landed on the moon then they would have blurted it out by now

  • Buen viernes maja @estefania218 :)

  • Buenos días mi querido Pepito!!! @pepitoelgrillo

  • Great man never dies

  • How did he get shadows like that????

  • He's shadow and the ariel shadow are at different angles ???

  • That's easy. @digbyjess. Go outside and put two sticks in the ground at different angles.

  • vmge55 5y ago

    Hermosos recuerdos. Y un saludo donde quiera que esté.

  • Only one question ??? Why men never came back at the moon??? Its hard to belive thats a real pic but... @nasagoddard


  • This was all made at universal studios

  • This is so fucken fake picture!!! There was NoT ever been a man on the moon! How come they never went back after all this years and plus we have a great technology !!!Stop the lies !!!

  • You guys saying it's fake should just go. You aren't wanted here, rest in peace Neil Armstrong.

  • @dutchchemtrails Your ignorance is obscene. For one, the quality was bad for video because it was in the 1960's, and second, it was being transmitted from the MOON! Do research before you call it fake. Also, the cameras were really good cameras. And today, we can up the quality on photos from the past.

  • @gecko_azul No it's not. Once again, just like I told the last guy, do research before you call anything fake. Neil did go to the moon, and set foot on it, along with Buzz. We haven't gone back because there isn't a need to go back!

  • @luciano_arruga There isn't a need to go back to the moon. That why.

  • @digbyjess @walsendi Remember where he is, he's on the moon, lights reflecting off of everything.

  • @vehiclegram oh i get it!!!! So one single trip to the moon was enough to tell theres no need to go back??? Bull shit!!! So it was the twinn american fucker that invented the airplane too???? Or the genius brazilian Santos Du Mount???? Of course theres no need to go never went there....

  • @luciano_arruga Yes it's possible. There wasn't water, or any life, why would we go back? Hmm? And don't bring up irrelevant shit.

  • @vehiclegram go back for water???? 80% of the earth is composed by water...Why search for water at the moon??? U americans are funny..... Or even life!!! Lol bla bla bla....

  • @luciano_arruga If there was water on the moon, that means there is life. Why do you think we're studying mars? Because we're seeing if the was or is life on it. We have found frozen water on mars. What? Trying to be nationalistic? Haha I love proving ignorant shots wrong.

  • @vehiclegram proving???? U havent prove nothing...just talk a bunch of shit!!!! Oh u guys have found frozen water on mars???? So tell me...what the fuck u gonna do with it???? Hahahah thats funny...u know kind of busy having a beer at the beach....stop boder talkink a bunch of shit...u cunts never been to the moon....and will neer be personly in mars....stop dreaming...fuck mars...fuck the moon...fucking boring places...why the fuck u want to get tbere anyways...go get laid...

  • @luciano_arruga Learn to speak some damn English. There's frozen water, so we can probably find life in mars! We have already found Archaebacteria on mars. I'm not talking shit, you're talking bad about Americans and saying we haven't been to the moon. We have been to the moon. You sound really jealous. Please do research then come talk to me. We have a rover on Mars, we can easily get people on Mars with a ton of planning. You need to ca down damn. We need to explore outer space. If not, what are we doing? Partying and throwing our life's away? You don't understand. Drunk your beer, get dumber, and try not to drown in the water.

  • Get laid? I have my good sir. See, I'm no nerd, I'm just not a dumbass like you :)

  • @luciano_arruga Yup. Need some ice?

  • @dutchchemtrails Yes they did, and the Russians want to go there because they haven't even been there yet. Only the USA has.

  • Why did the Russians never go? They had the technology. Why did the Russians stop short of going to the moon? Why did we really stop going to moon?

  • Because we know mostly all we need to know about the moon and it also costs a lot of money to go there @mikelplis

  • I understand that they could do so much more on the moon, but other than that I guess they did everything they wanted

  • There is life on the moon and mars and people are arguing over if we have been to the moon. Ridiculous. Most of the footage was fake but we have been to the moon what they found was beautiful! No im not talking about moon rocks. Other people think we are still using shuttles to go to the moon wake up. Its no surprise millions don't think HUMANS have been to the moon when most the footage released was fake. And the tech we apparently went there just isn't advanced enough but oh boy we went to the moon. The powers that be would prefer us to believe they didn't than what they found up there. Steven greer witness testaments. He has astronauts statements in there I suggest people have a listen rather than having childish arguments with eachother.

Hubble unveils a violent encounter of two galaxies becoming one, 250 million light-years away --- This image, captured by the NASA/ESA Hubble Space Telescope, shows what happens when two galaxies become one. The twisted cosmic knot seen here is NGC 2623 — or Arp 243 — and is located about 250 million light-years away in the constellation of Cancer (The Crab). NGC 2623 gained its unusual and distinctive shape as the result of a major collision and subsequent merger between two separate galaxies. This violent encounter caused clouds of gas within the two galaxies to become compressed and stirred up, in turn triggering a sharp spike of star formation. This active star formation is marked by speckled patches of bright blue; these can be seen clustered both in the center and along the trails of dust and gas forming NGC 2623’s sweeping curves (known as tidal tails). These tails extend for roughly 50 000 light-years from end to end. Many young, hot, newborn stars form in bright stellar clusters — at least 170 such clusters are known to exist within NGC 2623.

NGC 2623 is in a late stage of merging. It is thought that the Milky Way will eventually resemble NGC 2623 when it collides with our neighboring galaxy, the Andromeda Galaxy, in 4 billion years’ time.

Hubble released a set of celestial objects that were all the rage in the 1800's, thanks to astronomer Charles Messier —

In a nod to the global amateur #astronomy community, as well as to any space enthusiast who enjoys the beauty of the cosmos, the Hubble Space Telescope mission is releasing its version of the popular Messier catalog, featuring some of Hubble’s best images of these celestial objects that were once noted for looking like comets but turned out not to be.

This release coincides with the Orionid meteor shower — a spectacle that occurs each year when Earth flies through a debris field left behind by Halley’s Comet when it last visited the inner solar system in 1986. The shower will peak during the pre-dawn hours this Saturday, Oct. 21.

Nobody likes to hear "I told you so," but sometimes in science it's advantageous —

When the total solar eclipse swept across the United States on Aug. 21, 2017, NASA satellites captured a diverse set of images from space. But days before the eclipse, some NASA satellites also enabled scientists to predict what the corona — the Sun’s outer atmosphere — would look like during the eclipse, from the ground.
Image 1
Predictive Science, Inc. developed a numerical model that simulated what the corona would look like during the Aug. 21, 2017 total solar eclipse. Their model uses observations of magnetic fields on the Sun’s surface and requires a wealth of supercomputing resources to predict how the magnetic field shapes the corona over time.
Image 2
This is a photograph taken on the ground during the Aug. 21, 2017 total solar eclipse. “Based on a very preliminary comparison, it looks like the model did very well in capturing features of the large-scale corona,” Predictive Science president and scientist Jon Linker said.
Image 3
Due to STEREO-A’s position behind the Sun and the particular rotation rates of the Sun and Earth, STEREO-A’s view of the corona on Aug. 12, 2017, was virtually the same those within the path of totality would see nine days later on Aug. 21. That is, STEREO-A’s vantage point is roughly nine days in advance of Earth’s.

Image 4
An image from the joint ESA/NASA Solar and Heliospheric Observatory, or SOHO, which was positioned to share Earth’s view of the corona on Aug. 21 shows great similarity to STEREO-A’s view.

Southern African Agricultural "slash and burn" fires overwhelm landscape. --- The Suomi NPP satellite's instrument known as VIIRS (Visible Infrared Imaging Radiometer Suite) detected hundreds of fires burning in southern Africa on October 15, 2017. The fires are outlined in red. The location, widespread nature, and number of fires suggest that these fires were deliberately set to manage land. Places where traditional plots of open land is not available because the vegetation in the area is dense are the places where "slash and burn" agriculture is practiced most often. These regions include parts of Africa, northern South America, and Southeast Asia, where an abundance of grasslands and rainforests are found.

Farmers often use fire to return nutrients to the soil and to clear the ground of unwanted plants. While fire helps enhance crops and grasses for pasture, the fires also produce smoke that degrades air quality. In southern Africa, the agricultural burning season usually runs from June through September when the next growing season begins.

Hubble Turns its Gaze Towards New Gravitational-Wave Event —

The glow from this titanic collision, shining within the galaxy NGC 4993 is at a distance of 130 million light-years away. On August 17, 2017, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected gravitational waves from a neutron star collision within this galaxy. The event also resulted in a flare of light called a kilonova, which is visible to the upper left of the galactic center in this Hubble Space Telescope image.

@NASAHubble also obtained an infrared spectrum that may yield signs of exotic, radioactive elements. The analysis will continue while astronomers wait for the gravitational wave source to emerge from behind the Sun from Earth’s point of view, where it slipped just days after discovery.

NASA Satellite Sees a Tail of Smoke Over 500 Miles Long from California Fires --- ASA’s Terra satellite saw a stream of smoke that extended over 500 miles from various fires raging in northern California out over the Eastern Pacific Ocean.

The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Terra passed over California on Oct. 12 and captured a visible light image of the smoke plume. The MODIS image showed the stream of smoke extending from Santa Rosa, #California, located north of San Francisco, out into the Eastern Pacific, parallel to San Diego. A stream that stretched over 550 miles.

Hubble’s sees diminutive galaxy with a shocking rate of star production -- As far as galaxies are concerned, size can be deceptive. Some of the largest galaxies in the Universe are dormant, while some dwarf galaxies, such as ESO 553-46 imaged here by the NASA/ESA Hubble Space Telescope (@nasahubble), can produce stars at a hair-raising rate. In fact, ESO 553-46 has one of the highest rates of star formation of the 1,000 or so galaxies nearest to the Milky Way. No mean feat for such a diminutive galaxy!

Clusters of young, hot stars are speckling the galaxy, burning with a fierce blue glow. The intense radiation they produce also causes surrounding gas to light up, which is bright red in this image. The small mass and distinctive coloring of galaxies of this type prompted astronomers to classify them, appropriately, as blue compact dwarfs.

Wildfires in California Not Slowing Down

Wildfires continue to cause widespread destruction in the Sonoma Valley and Napa Valley areas of #California. Hot, dry conditions, high winds, and lack of water in the area continue to hamper firefighter efforts in fighting these fires. Thousands of structures have been burned and stark landscapes show acres of standing fireplaces as the only structures that survived the fires that spread through neighborhoods. New evacuations have been called for as the fires continue to ravage this area of California. #nasagoddard #wildfire
Today's @dictionarycom Word of the Day is "astrobleme," a scar on Earth's surface produced by the impact of a meteorite or asteroid.

Lake Manicouagan in northern Quebec, Canada, lies in one of the largest impact craters still preserved on Earth's surface. The lake itself surrounds a central uplift of the impact structure, which is about 70 kilometers in diameter and composed of broken fragments of minerals and rock. Overtime glaciation and other erosional processes have reduced the size of the crater.

The impact that formed Manicouagan is thought to have occurred about 212 million years ago, and some scientists believe it may have been responsible for a mass extinction that wiped out more than half of all living species. Today Lake Manicouagan serves as a reservoir and is one of Quebec's most important regions for Atlantic salmon fishing.

At a distance of just 160,000 light-years, the Large Magellanic Cloud is one of the Milky Way’s closest companions. It is also home to one of the largest and most intense regions of active star formation known to exist anywhere in our galactic neighborhood — the Tarantula Nebula. This NASA/ESA Hubble Space Telescope image shows both the spindly, spidery filaments of gas that inspired the region’s name, and the intriguing structure of stacked “bubbles” that forms the so-called Honeycomb Nebula (to the lower left). The Honeycomb Nebula was found serendipitously by astronomers using ESO’s New Technology Telescope to image the nearby SN1987A, the closest observed supernova to Earth for more than 400 years. The nebula’s strange bubble-like shape has baffled astronomers since its discovery in the early 1990s. Various theories have been proposed to explain its unique structure, some more exotic than others.

In 2010, a group of astronomers studied the nebula and, using advanced data analysis and computer modelling, came to the conclusion that its unique appearance is likely due to the combined effect of two supernovae — a more recent explosion has pierced the expanding shell of material created by an older explosion. The nebula’s especially striking appearance is suspected to be due to a fortuitous viewing angle; the honeycomb effect of the circular shells may not be visible from another viewpoint.

A NASA Black Brant IX sounding rocket carrying a parachute test platform was successfully launched at 6:45 a.m. EST, October 4, from the agency’s Wallops Flight Facility in Virginia.

The 58-foot tall rocket carried the Advanced Supersonic Parachute Inflation Research Experiment (ASPIRE) from NASA’s Jet Propulsion Laboratory in Pasadena, Calif. The mission is to evaluate the performance of the ASPIRE payload, which is designed to test parachute systems in a low-density, supersonic environment.

The next launch currently scheduled from Wallops is Orbital ATK’s Antares rocket carrying the Cygnus spacecraft with supplies and experiments to the International Space Station. Antares is scheduled for launch no earlier than November 10.

Three distinct solar active regions with towering arches rotated into view over a three-day period from Sept. 24-26, 2017. Charged particles spinning along the ever-changing magnetic field lines above the active regions trace out the magnetic field in extreme ultraviolet light, captured here by NASA’s Solar Dynamics Observatory. Extreme ultraviolet light is typically invisible to our eyes, but is colorized here in gold. To give some sense of scale, the largest arches are many times the size of Earth.

Did you ever wonder what a galaxy surrounded by a swarm of star clusters looked like? Oh, and those small smudges in the background - they took several hundred million to billions of years to reach us!

In the center of a rich cluster of galaxies located in the direction of the constellation of Coma Berenices, lies a galaxy surrounded by a swarm of star clusters. NGC 4874 is a giant elliptical galaxy, about ten times larger than the Milky Way, at the center of the Coma Galaxy Cluster. With its strong gravitational pull, it is able to hold onto more than 30,000 globular clusters of stars, more than any other galaxy that we know of, and even has a few dwarf galaxies in its grasp.

In this NASA/ESA Hubble Space Telescope image, NGC 4874 is the brightest object, located to the right of the frame and seen as a bright star-like core surrounded by a hazy halo. A few of the other galaxies of the cluster are also visible, looking like flying saucers dancing around NGC 4874. But the really remarkable feature of this image is the point-like objects around NGC 4874, revealed on a closer look: almost all of them are clusters of stars that belong to the galaxy. Each of these globular star clusters contains many hundreds of thousands of stars.

Recently, astronomers discovered that a few of these point-like objects are not star clusters but ultra-compact dwarf galaxies, also under the gravitational influence of NGC 4874. Being only about 200 light-years across and mostly made up of old stars, these galaxies resemble brighter and larger versions of globular clusters. They are thought to be the cores of small elliptical galaxies that, due to the violent interactions with other galaxies in the cluster, lost their gas and surrounding stars.

This Hubble image also shows many more distant galaxies that do not belong to the cluster, seen as small smudges in the background. While the galaxies in the Coma Cluster are located about 350 million light-years away, these other objects are much farther out. Their light took several hundred million to billions of years to reach us.

NASA’s OSIRIS-REx Snaps Pictures of Earth and the Moon

This black-and-white image of the Earth-Moon system was captured on Sept. 25, 2017 by NavCam 1, one of three cameras that comprise TAGCAMS (the Touch-and-Go Camera System) on NASA’s OSIRIS-REx spacecraft. At the time this image was taken, the spacecraft was retreating from Earth after performing an Earth Gravity Assist maneuver on Sept. 22. Earth and the Moon are shown 249,000 miles (401,200 kilometers) apart, and the spacecraft is 804,000 miles (1,297,000 kilometers) from Earth and 735,000 miles (1,185,000 kilometers) from the Moon.

NASA Tracking Hurricane Maria on Bahamas Approach

NASA-NOAA's Suomi NPP satellite provided a look at Maria's temperatures to find the strongest sides of the storm, while NOAA's GOES satellite revealed the extent of the storm in a visible image as it moved toward the Bahamas.

On Sept. 22 at 3:18 a.m. EDT (0718 UTC) the VIIRS instrument aboard NASA-NOAA's Suomi NPP satellite provided a thermal image of Hurricane Maria north of Hispaniola and nearing the Bahamas. The image showed highest coldest clouds around the eyewall and in bands of thunderstorms to the northeast and south and southeast of the center, stretching over Hispaniola and Puerto Rico. Those clouder clouds have the capability of producing heavy rainfall.

Hubble's spies a cool galaxy with a hot corona, 150 million light-years from Earth

Galaxy NGC 6753, imaged here by the NASA/ESA Hubble Space Telescope, is a whirl of color — the bursts of blue throughout the spiral arms are regions filled with young stars glowing brightly in ultraviolet light, while redder areas are filled with older stars emitting in the cooler near-infrared.

But there is more in this galaxy than meets the Hubble eye. At 150 million light-years from Earth, astronomers highlighted NGC 6753 as one of only two known spiral galaxies that were both massive enough and close enough to permit detailed observations of their coronas. Galactic coronas are huge, invisible regions of hot gas that surround a galaxy’s visible bulk, forming a spheroidal shape. Coronas are so hot that they can be detected by their X-ray emission, far beyond the optical radius of the galaxy. Because they are so wispy, these coronas are extremely difficult to detect.

Galactic coronas are an example of telltale signs astronomers seek to help them determine how galaxies form. Despite the advances made in past decades, the process of galaxy formation remains an open question in astronomy. Various theories have been suggested, but since galaxies come in all shapes and sizes — including elliptical, spiral, and irregular — no single theory has so far been able to satisfactorily explain the origins of all the galaxies we see throughout the Universe.

This @nasahubble picture shows NGC 5398, a barred spiral galaxy located about 55 million light-years away.

The galaxy is famous for containing an especially extensive HII region, a large cloud composed of ionized hydrogen (or HII, pronounced “H-two,” with H being the chemical symbol for hydrogen and the “II” indicating that the atoms have lost an electron to become ionized). NGC 5398’s cloud is named Tol 89 and sits at the lower left end of the galaxy’s central “bar” of stars, a structure that cuts through the galactic core and funnels material inwards to maintain the star formation occurring there.

Tol 86 is conspicuous in being the only large massive star-forming complex in the entire galaxy, with an extension of roughly 5,000 times; it contains at least seven young and massive star clusters. The two brightest clumps within Tol 89, which astronomers have named simply “A” and “B” appear to have undergone two bursts of star-forming activity — “starbursts” — roughly 4 million and less than 3 million years ago respectively. Tol 89-A is thought to contain a number of particularly bright and massive stars known as Wolf-Rayet stars, which are known for their high temperatures and extreme stellar winds.
