Astronomers at Newcastle University and Colby College have developed a new technique to determine how likely it is that two galaxies are very close together...
SSN 7 is a so-called contact binary located in the Small Magellanic Cloud, a dwarf galaxy some 210,000 light-years away in the constellation of Tucana....
Arp 220 is the result of a collision between two spiral galaxies; the enormous object glows brightest in infrared light, making it an ideal target for...
The newly-discovered supermassive black hole resides in a compact star-forming galaxy around 7.7 billion years away and has a mass of 20 million solar...
Ultramassive black holes with extreme masses of over 50 billion solar masses can be formed in the rare events that are multiple quasar mergers happening...
According to observations and cosmological simulations, dwarf galaxies are the most abundant type of galaxies in the early Universe and the galaxy merger...
In 2015, astrophysicists for the first time detected gravitational waves, ripples in space-time that occur when neutron star or black hole mergers disrupt...
Astronomers using the NASA/ESA Hubble Space Telescope have produced an outstanding image of a trio of merging galaxies called SDSSCGB 10189.
This Hubble...
The Andromeda galaxy (Messier 31), which is located 2.5 million light-years away, is the Milky Way’s nearest large galactic neighbor. By measuring the...
Princeton Plasma Physics Laboratory physicists Deepen Garg and Ilya Dodin say they can better understand the state of the cosmos shortly after the Big...
While close together in cosmological terms at just 750 light-years apart, or 6x the black hole sphere of influence, the supermassive black holes in the...
Astronomers have examined data about 700 short gamma-ray bursts (GRBs) detected with NASA’s Neil Gehrels Swift Observatory, Fermi Gamma-ray Space Telescope,...
Gamma-ray bursts (GRBs) come in two varieties, long and short. Long GRBs, which last a couple of seconds to one minute, form when a star at least 10 times...
The Webb team has released a beautiful photo taken by the NASA/ESA/CSA James Webb Space Telescope of ZW II 96, a merging galaxy pair in the constellation...
Astronomers say we may be witnessing a merger of two small galaxies just 400 million years after the Big Bang.
The galaxy cluster MACS0647 acts as a cosmic...
NASA has released a stunning image snapped by the NASA/ESA/CSA James Webb Space Telescope of IC 1623, an ongoing cosmic collision between two irregular...
GW170817, a titanic collision between two neutron stars detected in August 2017, ejected a structured relativistic jet with a speed greater than 99.97%...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) and the NASA/ESA Hubble Space Telescope have observed SDSS J144845.91+101010.5,...
