Using new observations with the ALMA telescope array in Chile, researchers have compiled the most precise map of three regions in the Milky Way's Central Molecular...
Apples-to-apples comparisons in the distant universe are hard to come by. Whether the subject is dwarf galaxies, supermassive black holes, or 'hot Jupiters,' astronomers can spend...
The universe is decaying much faster than thought. This is shown by calculations of scientists on the so-called Hawking radiation. They calculate that the last stellar...
The European Space Agency's Gaia mission has spotted an unusual family of stars all strangely eager to leave home -- a family we couldn't have discovered...
The NASA New Horizons spacecraft's extensive observations of Lyman-alpha emissions have resulted in the first-ever map from the galaxy at this important ultraviolet wavelength, providing a...
Researchers have developed a new coronagraph that could make it possible to see distant exoplanets obscured by light from their parent stars.
An international team has discovered the most distant spiral galaxy candidate known to date. This ultra-massive system existed just one billion years after the Big Bang...
Astronomers are investigating the longest and most energetic bursts of X-rays seen from a newly awakened black hole. Watching this strange behavior unfold in real time...
Astronomers have peered back in time to find what looks like a population of 'hidden' galaxies that could hold the key to unlocking some of the...
Every galaxy is thought to form at the center of a dark matter halo. Stars are formed when gravity within dark matter halos draws in gas,...
