Peering deep into the vast stellar halo that envelops our Milky Way galaxy, astronomers using NASA’s Hubble Space Telescope have uncovered tantalizing evidence for the possible existence of a shell of stars that are a relic of cannibalism by our Milky Way.

This illustration shows the disk of our Milky Way galaxy, surrounded by a faint, extended halo of old …
I happened to be surfing through various random sites today when I came across this site that’s actually been created as an experiment by some of the bods over at Google.
Called “100,000 Stars“, it’s an interactive visualization of the stellar neighborhood created for the Google Chrome web browser – don’t worry it works just as well in … Read the rest of this article
Two of NASA’s Great Observatories, the Spitzer and Hubble space telescopes, have teamed up to uncover a mysterious infant star that behaves like a police strobe light.

A star thought to have passed the age at which it can form planets may, in fact, be creating new worlds. The disk of material surrounding the surprising star called TW Hydrae may be massive enough to make even more planets than we have in our own solar system.

In this new view of the Andromeda galaxy from ESA’s Herschel space observatory, cool lanes of forming stars are revealed in the finest detail yet.
Andromeda, also known as M31, is the nearest major galaxy to our own Milky Way at a distance of 2.5 million light-years, making it an ideal natural laboratory to study star formation and galaxy evolution.… Read the rest of this article

This composite of the giant barred spiral galaxy NGC 6872 combines visible light images from the European Southern Observatory’s Very Large Telescope with far-ultraviolet (1,528 angstroms) data from NASA’s GALEX and 3.6-micron infrared data acquired by NASA’s Spitzer Space Telescope. A previously unsuspected tidal dwarf galaxy candidate (circled) appears only in the ultraviolet, indicating the presence of many hot young …

This artist’s conception illustrates the brown dwarf named 2MASSJ22282889-431026. NASA’s Hubble and Spitzer space telescopes observed the object to learn more about its turbulent atmosphere. Brown dwarfs are more massive and hotter than planets but lack the mass required to become sizzling stars. Their atmospheres can be similar to the giant planet Jupiter’s. Spitzer and Hubble simultaneously observed the object …
Researchers using the Stratospheric Observatory for Infrared Astronomy (SOFIA) have captured new images of a ring of gas and dust seven light-years in diameter surrounding the supermassive black hole at the center of the Milky Way, and of a neighboring cluster of extremely luminous young stars embedded in dust cocoons.

Unlike with some blockbuster films, the sequel to a movie from NASA’s Chandra X-ray Observatory is better than the first. This latest movie features a deeper look at a fast moving jet of particles produced by a rapidly rotating neutron star, and may provide new insight into the nature of some of the densest matter in the universe.
The hero … Read the rest of this article

This new view of spiral galaxy IC 342, also known as Caldwell 5, includes data from NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR. High-energy X-ray data from NuSTAR have been translated to the color magenta, and superimposed on a visible-light view highlighting the galaxy and its star-studded arms. NuSTAR is the first orbiting telescope to take focused pictures of the …
