With an estimated distance of 140 parsecs (457 light-years), the L-subdwarf star CWISE J124909+362116.0 (J1249+36 for short) has a total speed of at least...
Astrophysicists from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Collaboration have found evidence for gravitational waves...
According to quantum mechanics, a vacuum state is populated by virtual particle pairs undergoing spontaneous creation and annihilation processes. These...
Using the NASA/ESA Hubble Space Telescope and other space and ground-based observatories, astronomers have discovered SDSS J0749+2255, a closely bound...
This is the first time such an effect, known as precession, has been seen in black holes, where the twisting is 10 billion times faster than in previous...
In April 2019, the Event Horizon Telescope (EHT) Collaboration released stunning images of M87*, a 6.5-billion-solar-mass black hole in the center of the...
Astrophysicists from the LIGO-Virgo-KAGRA Collaboration have detected a further 35 gravitational waves since the last catalog release in October 2020,...
The Andromeda galaxy is a barred spiral galaxy 2.5 million light-years from Earth. Otherwise known as Messier 31, it hosts a double nucleus, which is well-explained...
By combining gravitational lensing with the capabilities of NASA’s Chandra X-ray Observatory, astronomers have detected two X-ray-emitting objects —...
While most of the binary black-hole mergers recently detected by NSF’s Laser Interferometer Gravitational-Wave Observatory (LIGO) in the United States...
Using the Arecibo and Gemini observatories, astronomers have detected a mobile supermassive black hole in a galaxy called SDSS J043703.67+245606.8 (hereafter...
Astronomers using the twin LIGO detectors located in Livingston, Louisiana, and Hanford, Washington, and the Virgo detector located near Pisa, Italy, have...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have mapped the distribution of molecular gas in NGC 6240, a nearby merging galaxy...
Do supermassive black holes have friends? The nature of galaxy formation suggests that the answer is yes, and in fact, pairs of supermassive black holes...
For the first time, a new computer simulation that incorporates the physical effects of Einstein’s general theory of relativity shows that gas in supermassive...
NGC 6240 is a pair of merging galaxies approximately 400 million light-years away in the constellation Ophiuchus. It spans 300,000 light-years and has...
Using X-ray data from NASA’s Chandra X-ray Observatory and optical data from ground-based telescopes, astronomers have spotted what could be the most...
