The mystery of galaxies in the early Universe just got even weirder. A team of astronomers has identified a giant spiral galaxy so well-formed that it already has a stable galactic bar; a long, ...
The researchers recorded a small number of unexplained signals suspected to be lightweight dark matter. A cutting-edge ...
In this combination of images from NASA/ESA shows three future scenarios for Milky Way & Andromeda encounter. Top left: Galaxies bypass at 1 million light-year separation. Top right: At 500,000 ...
NASA's advanced observatories have unveiled the Milky Way's hidden beauty, from its dense core with a supermassive black hole ...
New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...
The Milky Way's satellite galaxies are less typical than previously thought. Most Milky Way-like galaxies have star-forming satellite galaxies, unlike our own. The Milky Way's unique satellite galaxy ...
The discovery reinforces established theories about space. There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers. As many as ...
As a 'gem' at the end of stellar evolution, a pulsar is essentially a rapidly spinning neutron star. When a massive star reaches the end of its life, it expels its outer material into the universe in ...
NASA says something strange is happening with our Universe and how quickly it's expanding. Scientists have been studying new data from the Hubble Space Telescope. They say the expansion rate has ...
Recently, the astronomical community celebrated a groundbreaking discovery—scientists have observed a supermassive black hole that is located 3,000 light-years away from the center of a smaller dwarf ...
CAPE CANAVERAL, Fla. (AP) — It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all. Astronomers reported Monday that the probability of the two ...
