Using observations and archival data from several space- and ground-based telescopes, astronomers have discovered a rich population of free-floating planets...
Sagittarius A*, supermassive black hole at the center of our Milky Way Galaxy, has a mass of 4.3 million times that of the Sun, according to an analysis...
Using data from ESA’s Gaia satellite and archival spectroscopic surveys, astronomers have mapped the Milky Way disk substructure at distances over 10,000...
Astronomers have uncovered evidence that Sagittarius A*, the 4-million-solar-mass black hole at the center of our Milky Way Galaxy, is not a sleeping monster...
Astronomers using the Gemini Multi-Object Spectrograph (GMOS) on Gemini South telescope have imaged the Chamaeleon Infrared Nebula, which is located near...
A black hole in the center of a dwarf spheroidal galaxy called Leo I is almost as massive as the central black hole of our own Milky Way Galaxy.
The dwarf...
Hydrogen is the most abundant element. When a neutral hydrogen atom gets blasted with energy, its electron can be boosted to a larger orbit with a higher...
The question of whether we are alone in the Universe has been a source of wonder for humanity for millennia or more. Advances in planetary sciences, astronomy,...
Variations in the brightness of light seen from around a stellar-mass black hole in the binary system MAXI J1820+070 were caused by a huge warp in its...
The North Polar Spur and the Fan Region are two bright, large-scale radio structures that are seen on opposite sides of the sky. According to new research,...
An open cluster called NGC 1605 is in fact two merging open clusters with evidence of tidal streams, according to new research by Professor Denilso Camargo...
Astronomers using CSIRO’s ASKAP and South African Radio Astronomy Observatory’s MeerKAT radio telescopes have discovered and characterized ASKAP J173608.2-321635,...
The 490-light-year-wide void is located among the constellations Perseus and Taurus, and was formed by one powerful supernova or a series of such events...
New research led by University of Hong Kong astronomers shows that a fast expanding nebula called Pa 30 surrounding the hot Wolf-Rayet star IRAS 00500+6713...
Astronomers using the NASA/ESA Hubble Space Telescope have captured the brilliance of a globular cluster called Palomar 6.
This Hubble image shows the...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found thousands of dense gas clumps but, surprisingly, no star formation,...
