a_windows_to_universe IC 1795: The Fishhead Nebula
Image Credit & Copyright: Bill Snyder (Bill Snyder Photography)
Explanation: To some, this nebula looks like the head of a fish. However, this colorful cosmic portrait really features glowing gas and obscuring dust clouds in IC 1795, a star forming region in the northern constellation Cassiopeia. The nebula's colors were created by adopting the Hubble false-color palette for mapping narrow emission from oxygen, hydrogen, and sulfur atoms to blue, green and red colors, and further blending the data with images of the region recorded through broadband filters. Not far on the sky from the famous Double Star Cluster in Perseus, IC 1795 is itself located next to IC 1805, the Heart Nebula, as part of a complex of star forming regions that lie at the edge of a large molecular cloud. Located just over 6,000 light-years away, the larger star forming complex sprawls along the Perseus spiral arm of our
Milky Way Galaxy . At that distance, this picture would span about 70 light-years across IC 1795. #hubble #nebula #space #milkyway #moon #nebulosa #vialactea #star #luna #taylorswift #gravedad #gravity #amazing #wonderful #sky #cielo #astronomy #astronomia #repost #telescopio #telescope #galaxia #galaxies #Wikipedia @nasa #ESA #JPL #cosmos #vida #life #fish

a_windows_to_universe Explanation: What created the Waterfall Nebula? No one knows. The structure seen in the region of NGC 1999 in the Great Orion Molecular Cloud complex is one of the more mysterious structures yet found on the sky. Designated HH-222, the elongated gaseous stream stretches about ten light years and emits an unusual array of colors. One hypothesis is that the gas filament results from the wind from a young star impacting a nearby molecular cloud. That would not explain, however, why the Waterfall and fainter streams all appear to converge on a bright but unusual non thermal radio source located toward the upper left of the curving structure.
Another hypothesis is that the unusual radio source originates from a binary system containing a hot white dwarf, neutron star, or
black hole, and that the Waterfall is just a jet from this energetic system. Such systems, though, are typically strong X-rays emitters, and no X-rays have been detected. For now, this case remains unsolved. Perhaps well-chosen future observations and clever deductive reasoning will unlock the true origin of this enigmatic wisp in the future. #hubble #nebula #space #milkyway #moon #nebulosa #vialactea #star #luna #taylorswift #gravedad #gravity #amazing #wonderful #sky #cielo #astronomy #astronomia #repost #telescopio #telescope #galaxia #galaxies #Wikipedia @nasa #ESA #JPL #cosmos #vida #lifei

spaceattraction Saturn can be seen with the naked eye.
It is the fifth brightest object in the solar system and is also easily studied through binoculars or a small telescope

_acrosstheskies_ NGC 6357 is a diffuse nebula in the constellation Scorpius. The nebula contains many proto-stars shielded by dark disks of gas, and young stars wrapped in expanding gases surrounding these small stars. It is also known as the Lobster Nebula. Image by the HST.

machineguts Occasionally I like to share pieces from my personal collection! This is a very rare white fluorite octagon with purple and blue banding. White (colourless) fluorite is one of the rarest of all fluorite colours.

Cosmic Kaleidoscope: At first glance, this cosmic kaleidoscope of purple, blue and pink offers a strikingly beautiful - and serene - snapshot of the cosmos. However, this multi-colored haze actually marks the site of two colliding galaxy clusters, forming a single object. The cluster is located about 4.3 billion light-years from Earth.

As with all galaxy clusters, this one contains a significant amount of dark matter, which leaves a detectable imprint in visible light by distorting the images of background galaxies. In this image, this dark matter appears to align well with the blue-hued hot gas, suggesting that the two clusters have not yet collided; if the clusters had already smashed into one another, the dark matter and gas would have separated. It also contains other features - such as a compact core of hot gas - that would likely have been disrupted had a collision already occurred.

still_explorers We all have a childish spirit inside us, willing to explore even the most unknown regions, with the hope of knowing more. If we are going to manufacture hope for the entirety of humanity on this planet, then we must channel this inner curiosity and take our first steps toward other stars.

A solar flare is a sudden brightening observed over the Sun’s surface. This picture captured by the NASA’s Solar Dynamics Observatory illustrates one of these beautiful prominences. This phenomena sent out particles and a third radiation belt that traveled near Earth a few days later. #sun #space #stellar #stars #nasa #iss #hubble #spitzer #telescope #astrological #galaxy #galaxies #astronomical #nebula #cosmic #universe #milkway #chandra #interstellar #supernova

_science_is_amazing Hubble spies NGC 4394

Discovered in 1784 by the German–British astronomer William Herschel, NGC 4394 is abarred spiral galaxy situated about 55 million light-years from Earth. The galaxy lies in the constellation of Coma Berenices (Berenice's Hair), and is considered to be a member of theVirgo Cluster.

NGC 4394 is the archetypal barred spiral galaxy, with bright spiral arms emerging from the ends of a bar that cuts through the galaxy’s central bulge. These arms are peppered with young blue stars, dark filaments of cosmic dust, and bright, fuzzy regions of active star formation. At the centre of NGC 4394 lies a region of ionised gas known as a LINER. LINERs are active regions that display a characteristic set of emission lines in their spectra— mostly weakly ionised atoms of oxygen, nitrogen and sulphur.

Although LINER galaxies are relatively common, it’s still unclear where the energy comes from to ionise the gas. In most cases it is thought to be the influence of a black hole at the centre of the galaxy, but it could also be the result of a high level of star formation. In the case of NGC 4394, it is likely that gravitational interaction with a nearby neighbour has caused gas to flow into the galaxy’s central region, providing a new reservoir of material to fuel the black hole or to make new stars.
