A massive white dwarf star with a bizarre carbon-rich atmosphere could be two white dwarfs merged together according to an international team led by University of Warwick astronomers, and only narrowly avoided destruction.

Scientists studying a distant galaxy cluster have discovered the biggest explosion seen in the Universe since the Big Bang.

The Force Is Strong In Neutron Stars

Most ordinary matter is held together by an invisible subatomic glue known as the strong nuclear force -- one of the four fundamental forces in nature, along with gravity, electromagnetism, and the weak force. The strong nuclear force is responsible for the push and pull between protons and neutrons in an atom's nucleus, which keeps an atom from collapsing in on itself.

Hubble Fingerprints Galaxy NGC 4689

The NASA/ESA Hubble Space Telescope is no stranger to spiral galaxies. The telescope has brought us some of the most beautiful images ever taken of our spiral neighbors -- and the galaxy known as NGC 4689 is no exception.

An international team of astronomers led by scientists at the University of California, Riverside, has found an unusual monster galaxy that existed about 12 billion years ago, when the universe was only 1.8 billion years old, or 13 percent of its current age of 13.8 billion years.

Scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA) have completed the Extremely Low Mass -- also known as ELM -- spectroscopic study of white dwarf stars in the Sloan Digital Sky Survey (SDSS).

NASA Scientist Al Kogut has found a way to do Hubble Space Telescope-class science from a relatively inexpensive scientific balloon and is well on the way to proving the concept.

An international team of astrophysicists led by Australian Professor Matthew Bailes, from the ARC Centre of Excellence of Gravitational Wave Discovery (OzGrav), has shown exciting new evidence for 'frame-dragging'.

NASA scientists using virtual reality technology are redefining our understanding about how our galaxy works.

The Tarantula Nebula, seen in this image by the Spitzer Space Telescope, was one of the first targets studied by the infrared observatory after its launch in 2003.

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.
