Astronomers have found a 'vampire' star in the midst of a feeding frenzy, with the help of an automated program that is sifting through archived data from the decommissioned Kepler Space Telescope.

NASA is celebrating the legacy of one of its Great Observatories, the Spitzer Space Telescope, which has studied the universe in infrared light for more than 16 years. The Spitzer mission will come to a close on Jan. 30.

ESA's XMM-Newton has discovered that gas lurking within the Milky Way's halo reaches far hotter temperatures than previously thought and has a different chemical make-up than predicted, challenging our understanding of our galactic home.

Astrophysicists have come a step closer to understanding the origin of a faint glow of gamma rays covering the night sky.

ESA's XMM-Newton X-ray observatory has spied hot gas sloshing around within a galaxy cluster - a never-before-seen behaviour that may be driven by turbulent merger events.

The dwarf galaxy Gaia-Enceladus collided with the Milky Way probably approximately 11.5 billion years ago.

When it comes to the biggest and brightest explosions seen in the Universe, University of Warwick astronomers have found that it takes two stars to make a gamma-ray burst.

Astronomers have cataloged signs of 9 heavy metals in the infrared light from supergiant and giant stars.

A team of astronomers using NASA's Hubble Space Telescope has measured the universe's expansion rate using a technique that is completely independent of any previous method.

One of the brightest and most massive star-forming regions in our galaxy, the Omega, or Swan, Nebula, came to resemble the shape resembling a swan's neck we see today only relatively recently.

A galaxy about 23 million light years away is the site of impressive, ongoing fireworks. Rather than paper, powder and fire, this galactic light show involves a giant black hole, shock waves and vast reservoirs of gas.

Look at this new radio image covered with dots, each of which is a distant galaxy! The brightest spots are galaxies that are powered by supermassive black holes and shine bright in radio light.

ESO's Very Large Telescope (VLT) has observed the central part of the Milky Way with spectacular resolution and uncovered new details about the history of star birth in our galaxy.

The Origins Space Telescope (Origins) traces our cosmic history, from the formation of the first galaxies and the rise of metals to the development of habitable worlds and present-day life.

How to Shape a Spiral Galaxy

Our Milky Way galaxy has an elegant spiral shape with long arms filled with stars, but exactly how it took this form has long puzzled scientists. New observations of another galaxy are shedding light on how spiral-shaped galaxies like our own get their iconic shape.

Some of the most dramatic events in the universe occur when certain stars die -- and explode catastrophically in the process.

For decades, scientists have speculated about the origin of the electromagnetic radiation emitted from celestial regions that host black holes and neutron stars--the most mysterious objects in the universe.

In a paper on the preprint site ArXiv and soon to be published in the Astrophysical Journal, researchers present the first analysis of data from a new configuration of the MWA designed specifically to look for the signal of neutral hydrogen, the gas that dominated the universe during the cosmic dark age.

Giant Magnetic Ropes in a Galaxy's Halo

This image of the "Whale Galaxy" (NGC 4631), made with the National Science Foundation's Karl G. Jansky Very Large Array (VLA), reveals hair-like filaments of the galaxy's magnetic field protruding above and below the galaxy's disk.

We report the discovery of WISE2150-7520AB (W2150AB): a widely separated (~ 341 AU) very low mass L1 + T8 co-moving system.
