George Mason is the home for the new $19.5 million NASA Landolt Space Mission. Led by the College of Science’s Peter Plavchan, with the College of Engineering and Computing, this mission will launch an artificial star in orbit to help scientists calibrate telescopes and measure brightness.
Two superluminous quasars, or active black holes at the centers of large galaxies, were found just 900 million years after the Big Bang — the earliest detection of a pair of merging quasars ever seen.
New data revises our view of this unusual supernova explosion. A team of scientists used NASA’s James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. With the telescope’s MIRI (Mid-Infrared Instrument) and NIRCam (Near-Infrared Camera), the team gathered data that is […].
Astronomers discovered the first pair of merging quasars from the Cosmic Dawn, 900 million years after the Big Bang.
Using a specially designed 3D printed vacuum system, scientists have developed a way to “trap” dark matter with the aim of detecting domain walls. This will be a significant step forwards in unraveling some of the mysteries of the universe.
Using the James Webb Space Telescope (JWST), astronomers from the Space Telescope Science Institute (STScI) have discovered a new supernova. Designated SN 2023adsy, the newfound stellar explosion is the most distant Type Ia supernova so far detected. The finding was detailed in a research paper published June 7 on the pre-print server arXiv.
Astronomers believe that at the heart of most, if not all, galaxies sits a titanic black hole with a mass that is millions or even billions of times that of our sun. These supermassive black holes cannot be directly created through the collapse of a massive star, as is the case with stellar mass black holes with masses tens of times that of the sun, as no star is large enough to birth such a huge object.

“Stellar-mass black holes, which contain up to about 30 solar masses, possess much smaller event horizons and stronger tidal forces, which can rip apart approaching objects before they get to the horizon.”
The simulated black hole is designed to imitate the supermassive one at the heart of our galaxy, which has a mass over 4.3 million times that of our Sun. That is almost unfathomably large: the distant view of it you see in the visualizer is from nearly 400 million miles away.
