An analysis of data from the Pan-Andromeda Archaeological Survey (PAndAS) has uncovered two major episodes of accretion, probably separated by billions...
Using the Subaru, Keck, and Gemini telescopes, astronomers have discovered a young cluster of galaxies in the early Universe. Named z66OD, the protocluster...
Using data from several space- and ground-based telescopes, astronomers have discovered a system of three supermassive black holes within SDSS J084905.51+111447.2,...
Using data collected by the NASA/ESA Hubble Space Telescope, astronomers have created the deepest ever catalog of variable sources (variable stars in our...
A new visualization created by a team of astrophysicists at NASA’s Goddard Space Flight Center illustrates how black hole’s gravity distorts our view,...
High-speed particle jets from gamma-ray bursts may exceed the speed of light in surrounding gas clouds, but do so without violating Einstein’s theory...
In a new study, University of Chicago researcher Stephanie Olson and colleagues modeled climates and ocean habitats of different types of extrasolar planets...
Using data from the large scale structure of galaxies, the Cosmic Microwave Background (CMB), Type Ia supernovae, and Big Bang nucleosynthesis, a team...
Astronomers have announced the discovery of the most massive star ever known to be destroyed by a supernova explosion. Dubbed SN 2016iet, the explosive...
Using data from multiple space- and ground-based telescopes, an international team of astronomers has discovered 39 massive star-forming galaxies at a...
Dark matter, the mysterious substance that makes up roughly a quarter of the Universe, may have its origin in pre-Big-Bang times, according to a new paper...
An international team of astronomers has mapped the size and shape of the Local Void, a large underdense region of the Universe, on the outskirts of which...
The Hubble constant measures the current expansion rate of our Universe and plays a fundamental role in cosmology: it can be used to determine the Universe’s...
Astronomers using the Deep Synoptic Array-10 at the Owens Valley Radio Observatory have discovered a new non-repeating fast radio burst (FRB), called FRB...
Fast radio bursts (FRBs) are brief radio emissions from distant astronomical sources. Some are known to repeat, but most are single bursts, occurring only...
Astronomers using the NASA/ESA Hubble Space Telescope have confirmed the presence of ionized (electrically-charged) buckminsterfullerene in the interstellar...
Gamma-ray bursts (GRBs) are the most energetic explosions in the Universe, beaming out mighty jets which travel through space at 0.99 times the speed of...
According to new research led by Rochester Institute of Technology (RIT), the collision of the recently-discovered dwarf galaxy Antlia 2 with our Milky...
A starburst galaxy called ESO 495-21 is just 3,000 light-years across, but it harbors a black hole of about one million solar masses at its core. This...
