Astronomy TOP STORIES
Astronomers have used data from NASA's Chandra X-ray Observatory to make a discovery that may have profound implications for understanding how the magnetic field in the Sun and stars like it are generated.
Alone on the cosmic road, far from any known celestial object, a young, independent star is going through a tremendous growth spurt.
Astronomers at the University of Michigan's College of Literature, Science, and the Arts (LSA) discovered for the first time that the hot gas in the halo of the Milky Way galaxy is spinning in the same direction and at comparable speed as the galaxy's disk.
Celebrating its 50th anniversary this year, the TV series "Star Trek" has captured the public's imagination with the signature phrase, "To boldly go where no one has gone before."
Using NASA's Hubble Space Telescope, astronomers have conducted the first search for atmospheres around temperate, Earth-sized planets beyond our solar system and found indications that increase the chances of habitability on two exoplanets.
An international team of astronomers has discovered and confirmed a treasure trove of new worlds using NASA's Kepler spacecraft on its K2 mission.
The MeerKAT First Light image of the sky, released today by Minister of Science and Technology, Naledi Pandor, shows unambiguously that MeerKAT is already the best radio telescope of its kind in the Southern Hemisphere.
Gamma-ray bursts, or GRBs, are some of the most violent and energetic events in the universe.
A team of hundreds of physicists and astronomers have announced results from the largest-ever, three-dimensional map of distant galaxies.
The European Space Agency's orbiting X-ray observatory, XMM-Newton, has proved the existence of a "gravitational vortex" around a black hole.
An international team has made use of the power of the HAWK-I infrared instrument on ESO's Very Large Telescope (VLT) to produce the deepest and most comprehensive view of the Orion Nebula to date.
About 250 million light-years away, there's a neighborhood of our universe that astronomers had considered quiet and unremarkable.
Astronomers have "cracked" a very cold case with the dissection of light from the coldest known brown dwarf.
Peering deep into the core of the Crab Nebula, this close-up image reveals the beating heart of one of the most historic and intensively studied remnants of a supernova, an exploding star.
In its brief time gathering data this year, the Hitomi X-ray Observatory discovered something quite serene: the calm core in a massive cluster of galaxies.
This NASA/ESA Hubble Space Telescope image reveals the iridescent interior of one of the most active galaxies in our local neighborhood -- NGC 1569, a small galaxy located about eleven million light-years away in the constellation of Camelopardalis (The Giraffe).
Rochester Institute of Technology professors have developed a faster, more accurate way to assess gravitational wave signals and infer the astronomical sources that made them.
