This false-color view from NASA’s Cassini spacecraft shows clouds in Saturn’s northern hemisphere. The view was produced by space imaging enthusiast Kevin M. Gill, who also happens to be an engineer at NASA’s Jet Propulsion Laboratory.

The view was made using images taken by Cassini’s wide-angle camera on July 20, 2016, using a combination of spectral filters sensitive to infrared light at 750, 727 and 619 nanometers.

Filters like these, which are sensitive to absorption and scattering of sunlight by methane in Saturn’s atmosphere, have been useful throughout Cassini’s mission for determining the structure and depth of cloud features in the atmosphere.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA’s Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.

A galaxy fit to burst

This NASA/ESA Hubble Space Telescope image reveals the vibrant core of the galaxy NGC 3125. Discovered by John Herschel in 1835, NGC 3125 is a great example of a starburst galaxy — a galaxy in which unusually high numbers of new stars are forming, springing to life within intensely hot clouds of gas.

Located approximately 50 million light-years away in the constellation of Antlia (The Air Pump), NGC 3125 is similar to, but unfathomably brighter and more energetic than one of the Magellanic Clouds. Spanning 15 000 light-years, the galaxy displays massive and violent bursts of star formation, as shown by the hot, young, and blue stars scattered throughout the galaxy’s rose-tinted core. Some of these clumps of stars are notable — one of the most extreme Wolf–Rayet star clusters in the local Universe, NGC 3125-A1, resides within NGC 3125.

Despite their appearance, the fuzzy white blobs dotted around the edge of this galaxy are not stars, but globular clusters. Found within a galaxy’s halo, globular clusters are ancient collections of hundreds of thousands of stars. They orbit around galactic centres like satellites — the Milky Way, for example, hosts over 150 of them.

An image in my quest to have Quark hit on every man in DS9:

He gets wind of Miles having an Evil Villain RP side and gets really into the idea of Miles just threatening him with the gun a little bit.

Miles is confused and afraid.  They didn’t teach how to keep a ferengi out of your pants in Starfleet.


Andromeda in Infrared

This image of the Andromeda galaxy in infrared is the sharpest image ever taken of the dust in another spiral galaxy when it was taken. This image reveals the delicate tracings of spiral arms that reach into the very center of the galaxy. The fiery plumes of red contain millions of stars trapped within the dust that creates them.

Hubble finds ring of Dark Matter

Dark matter is the most common substance in the universe, scientists even estimate that it takes up approximately 25% of the entire universe. However, we can’t see it and we don’t even know what it is!

“Astronomers using NASA’s Hubble Space Telescope got a first-hand view of how dark matter behaves during a titanic collision between two galaxy clusters. The wreck created a ripple of dark matter, which is somewhat similar to a ripple formed in a pond when a rock hits the water. “

This ring gives @nasa scientists and researchers strong evidence that dark matter exists. To read more visit: NASA

What’s that in front of the Moon? It’s the International Space Station. Using precise timing, the Earth-orbiting space platform was photographed in front of a partially lit Moon last year. The featured image was taken from Madrid, Spain with an exposure time of only 1/1000 of a second. In contrast, the duration of the transit of the ISS across the entire Moon was about half a second. The sun-glinting station can be seen just to the dark side of the day / night line known as the terminator. Numerous circular craters are visible on the distant Moon, as well as comparatively rough, light colored terrain known as highlands, and relatively smooth, dark colored areas known as maria. On-line tools can tell you when the International Space Station will be visible from your area.

An Emission Nebula - NGC 6357

Far away in the constellation Scorpius, inside the core of the large emission nebula NGC 6357, lies the star cluster Pismis 24. Part of the nebula is ionised by the youngest stars in Pismis 24 - which are characterized by their blue light. The intense ultraviolet radiation from the blazing stars heats the gas surrounding the cluster and creates a bubble in NGC 6357. The presence of these surrounding gas clouds makes probing into the region even harder for Astronomers.

The Egg Nebula - CRL 2688

Around 3000 light-years from Earth in the constellation Cygnus is a planetary nebula known as the Egg Nebula. The nebula is the result of a dramatic phase in the life of a Sun-like star. Objects such as these occur as a dying star’s hot remains briefly illuminate the material it has expelled, lighting up the gas and dust surrounding it. The concentric rings seen in the less dense cloud surrounding the star are due to the star ejecting material at regular intervals. The ejection process typically orrurs every hundred years during a phase of the star’s evolution just prior to this preplanetary nebula phase. These dusty shells are not usually visible in these nebulas, but when they are it provides astronomers with a rare opportunity to study their formation and evolution.

This image of our Milky Way has several reasons to give us chills!

This image taken by the APEX telescope, located in Chile, allows astronomers to study the cold universe: the distribution of gas and dust that are barely a few tens of degrees above absolute zero.
