(PhysOrg.com) -- At the center of most galaxies lie supermassive black holes that can grow to become more than a billion times larger than our Sun. However, astrophysicists don’t fully understand the formation and evolution ...
(Phys.org)—Andromeda IV, discovered in 1972 by Canadian astronomer Sidney Van den Berghan, is believed to be an irregular satellite of our neighboring Andromeda galaxy, also known as Messier 31. Now, a new study conducted ...
(Phys.org)—Many black holes are believed to have surrounding accretion disks of matter trapped by gravity and spiraling toward the event horizon. Supercritical accretion disks (SCADs) are those with mass accretion rates ...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have conducted molecular line observations of a protostellar system known as VLA 1623. Results of the observational campaign, published June 18 on ...
Pulsars are among the most exotic celestial bodies known. They have diameters of about 20 kilometres, but at the same time roughly the mass of our sun. A sugar-cube sized piece of its ultra-compact matter on the Earth would ...
