nasagoddard Hubble sees a galaxy 60 million light-years away

This new NASA/ESA Hubble Space Telescope image shows the galaxy IC 335 in front of a backdrop of distant galaxies. IC 335 is part of a galaxy group containing three other galaxies, and located in the Fornax Galaxy Cluster 60 million light-years away.

As seen in this image, the disk of IC 335 appears edge-on from the vantage point of Earth. This makes it harder for astronomers to classify it, as most of the characteristics of a galaxy’s morphology — the arms of a spiral or the bar across the center — are only visible on its face. Still, the 45 000 light-year-long galaxy could be classified as an S0 type.

These lenticular galaxies are an intermediate state in galaxy morphological classification schemes between true spiral and elliptical galaxies. They have a thin stellar disk and a bulge, like spiral galaxies, but in contrast to typical spiral galaxies they have used up most of the interstellar medium. Only a few new stars can be created out of the material that is left and the star formation rate is very low. Hence, the population of stars in S0 galaxies consists mainly of aging stars, very similar to the star population in elliptical galaxies.

nasagoddard Holiday Lights on the Sun: Imagery of a Solar Flare

The sun emitted a significant solar flare, peaking at 7:28 p.m. EST on Dec. 19, 2014. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. This flare is classified as an X1.8-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.

nasagoddard A pulse of water released down the lower reaches of the Colorado River last spring resulted in more than a 40 percent increase in green vegetation where the water flowed, as seen by the Landsat 8 satellite. The March 2014 release of water – an experimental flow implemented under a U.S.-Mexico agreement called "Minute 319" – reversed a 12-year decline in the greenness along the delta.
Analysis of satellite images of pre-flow August 2013 to post-flow August 2014, scientists with the U.S. Geological Survey (USGS) calculated a 43 percent increase in green vegetation along the route wetted by the flow, called the inundation zone, and a 23 percent increase in greening of the riparian zone, or the river banks.
Scientists presented these and other results this week at the American Geophysical Union's Fall Meeting in San Francisco. Landsat 8 is a joint project of NASA and the USGS.

nasagoddard For all those people who have ever said, “I bet you can see my neighbor’s Christmas lights from space!” well, we now have proof that they’re right — at least in aggregate. For the first time, NASA researchers have measured the increase in Earth’s night lights during both the holiday period between Thanksgiving and New Years, in the U.S., and for the holy month of Ramadan in the Middle East.

While we may not be able to see individual front yards, the satellite data has such good resolution that researchers from Yale University have been able to find correlations between political and socio-economic data for individual neighborhoods and the brightness measured from space. Researchers say being able to monitor our lighting output in this way is like being able to measure traffic on a highway, rather than just map the road itself.

If we can understand the behavioral aspect of lights and energy use throughout the year it can shed light on our understanding of energy efficiency and human drivers of climate change.

nasagoddard The sun emitted a mid-level solar flare, peaking at 11:50 p.m. EST on Dec. 16, 2014. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

This flare is classified as an M8.7-class flare. M-class flares are a tenth the size of the most intense flares, the X-class flares. The number provides more information about its strength. An M2 is twice as intense as an M1, an M3 is three times as intense, etc.

nasagoddard 12.13.14

NOAA's GOES-East satellite captured this stunning view of the Americas on 12.13.14, December 13, 2014 at 17:45 UTC. The data from GOES-East was made into an image by the NASA/NOAA GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md.

GOES satellites provide the kind of continuous monitoring necessary for intensive data analysis. Geostationary describes an orbit in which a satellite is always in the same position with respect to the rotating Earth. This allows GOES to hover continuously over one position on Earth's surface, appearing stationary. As a result, GOES provide a constant vigil for the atmospheric "triggers" for severe weather conditions such as tornadoes, flash floods, hail storms and hurricanes.

nasagoddard A Hubble View of All That Glitters

This striking NASA/ESA Hubble Space Telescope image shows a glittering bauble named Messier 92. Located in the northern constellation of Hercules, this globular cluster — a ball of stars that orbits a galactic core like a satellite — was first discovered by astronomer Johann Elert Bode in 1777.

Messier 92 is one of the brightest globular clusters in the Milky Way, and is visible to the naked eye under good observing conditions. It is very tightly packed with stars, containing some 330,000 stars in total. As is characteristic of globular clusters, the predominant elements within Messier 92 are hydrogen and helium, with only traces of others. It is actually what is known as an Oosterhoff type II (OoII) globular cluster, meaning that it belongs to a group of metal-poor clusters — to astronomers, metals are all elements heavier than hydrogen and helium.

By exploring the composition of globulars like Messier 92, astronomers can figure out the age of these clusters. As well as being bright, Messier 92 is also old, being one of the oldest star clusters in the Milky Way, with an age almost the same as the age of the Universe.

nasagoddard Strong Pacific Storm System Affecting West Coast
This image was taken by the GOES West satellite on December 10, 2014. This strong Pacific storm system was forecast to bring some drought relief to California and Oregon through December 10, 2014. An atmospheric river of moisture, or pineapple express, was expected ahead of this system, tapping moisture from the tropics. This led to a swath of heavy rainfall, along with snow in the highest mountains of the Sierra Nevada and the northern California mountains.

The GOES series of satellites keep an eye on the weather happening over the continental U.S. and eastern Pacific and Atlantic Oceans. NASA's GOES Project, located at NASA's Goddard Space Flight Center in Greenbelt, Md., procures and manages the development and launch of the GOES series of satellites for NOAA and creates images and animations. The GOES satellites are operated by NOAA.

nasagoddard Cassini’s view of Jupiter’s southern hemisphere

This Cassini image shows Jupiter from an unusual perspective. If you were to float just beneath the giant planet and look directly up, you would be greeted with this striking sight: red, bronze and white bands encircling a hazy south pole. The multicoloured concentric layers are broken in places by prominent weather systems such as Jupiter’s famous Great Red Spot, visible towards the upper left, chaotic patches of cloud and pale white dots. Many of these lighter patches contain lightning-filled thunderstorms.

Jupiter has very dramatic weather – the planet’s axis is not as tilted (towards or away from the Sun) as much as Earth’s so it does not have significant seasonal changes, but it does have a thick and tumultuous atmosphere filled with raging storms and chaotic cloud systems.

These clouds, formed from dense layers of ammonia crystals, are tugged, stretched and tangled together by Jupiter’s turbulence and strong winds, creating vortices and hurricane-like storms with wind speeds of up to 360 km per hour.

The Great Red Spot is actually an anticyclone that has been violently churning for hundreds of years. It was at one stage large enough to contain several Earth-sized planets but recent images from the Hubble Space Telescope show it to be shrinking. There are other similarly striking storms raging in both Jupiter’s cool upper atmosphere and hotter lower layers, including a Great Dark Spot and Oval BA, more affectionately nicknamed Red Spot Jr.

nasagoddard A Delta IV Heavy #rocket lifts off from Space Launch Complex 37 at Cape Canaveral Air Force Station carrying NASA's #Orion spacecraft on an unpiloted flight test to Earth orbit. Liftoff was at 7:05 a.m. EST. During the two-orbit, four-and-a-half hour mission, engineers will evaluate the systems critical to crew safety, the launch abort system, the heat shield and the parachute system.

The spacecraft splashed down in the Pacific Ocean approximately 600 southwest of San Diego. The recovery team from NASA, the U.S. Navy and Lockheed Martin will perform initial recovery operations, including safing the crew module and towing it into the well deck of the USS Anchorage, a landing platform-dock ship.

  •   chuckcloninger I happened to be driving past Cape Kennedy one time when, to my surprise, a missile takeoff was planned. I pulled over to see why everyone else was pulled over (I didn't even know where I was) and I soon felt the ground begin to move and a rumble filled the air. It got louder and louder and I then saw the smoke and then the fire and then the missile lifting off. A huge bit of pride filled me and I was proud to be part of a nation that could do that. 1w

nasagoddard NASA’s Operation IceBridge completed four more surveys of the Antarctic, bringing the mission’s six-week-long field campaign to a close.

On Nov. 15, IceBridge carried out a newly-created mission designed to study the Institute Ice Stream near the Ronne Ice Shelf. On this flight researchers collected data on surface elevation, sub-ice bedrock and water depth along paths previously measured by NASA’s Ice, Cloud and Land Elevation Satellite, or ICESat, from 2003 to 2009. This region has been the subject of ground-based studies going back to the 1950s, airborne research by a joint U.S.–Danish project in the 1970s and an effort by Germany’s Alfred Wegener Institute in the 1990s.

nasagoddard Caption: The interactions between clouds and aerosols are illustrated in this image, taken by retired astronaut Chris Hadfield onboard the International Space Station. It shows contrails produced by aircraft (bright streaks) over the ocean. --
Turn on any local TV weather forecast and you can get a map of where skies are blue or cloudy. But for scientists trying to figure out how clouds affect the Earth’s environment, what's happening inside that shifting cloud cover is critical and hard to see.

To investigate the layers and composition of clouds and tiny airborne particles like dust, smoke and other atmospheric aerosols, , scientists at NASA’s Goddard Space Flight Center in Greenbelt, Maryland have developed an instrument called the Cloud-Aerosol Transport System, or CATS. The instrument, which launches to the International Space Station in December 2014, will explore new technologies that could also be used in future satellite missions.

From space, streaks of white clouds can be seen moving across Earth’s surface. Other tiny solid and liquid particles called aerosols are also being transported around the atmosphere, but these are largely invisible to our eyes. Aerosols are both natural and man-made, and include windblown desert dust, sea salt, smoke from fires, sulfurous particles from volcanic eruptions, and particles from fossil fuel combustion.

nasagoddard Ash plulme from Shiveluch, Kamchatka Peninsula, eastern Russia

On November 23, 2014 the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite flew over Russia’s Kamchatka’s Peninsula and captured this true-color image of a large volcanic plume pouring from Shiveluch Volcano. A strong vulcanian explosion at the volcano same day, with the ash plume rising approximately 8 km (5 mi) above the caldera. Although no lava flow has been reported, the plume extended for more than 200 km (124 mi). Shiveluch (also spelled Sheveluch) is one of the largest and most active volcanoes on Russia’s Kamchatka Peninsula. It has been spewing ash and steam intermittently—with occasional dome collapses, pyroclastic flows, and lava flows, as well—for the past decade.
