WISE discovers brightest galaxy in the universe

By - May 26, 2015 1 Picture

A fresh study examining data from NASA's Wide-field Infrared Survey Explorer (WISE) spacecraft has led to to the discovery of the brightest galaxy in the universe. The galaxy, dubbed WISE J224607.57-052635.0, is believed to contain in excess of 300 trillion stars, and has given rise to a new group of astronomical objects – Extremely Luminous Infrared Galaxies, or ELIRGs.

Researchers theorize two mechanisms that prevent prolific star creation in galaxy clusters

By - March 11, 2015 1 Picture
For a long time, scientists have been searching for an answer as to how galaxy clusters regulate the number of stars they create. Given that the amount of interstellar gas used to create the stellar giants exists in such abundance, this theoretically allows for the creation of many times the current number of stars. A team of researchers from MIT, Columbia University and Michigan State University believe they have found the answer. Read More

NASA aims to unlock mysteries of celestial giants by observing rare black hole

By - March 2, 2015 2 Pictures
Ever since they were theorized by Albert Einstein's theory of general relativity back in 1915, black holes have captured the imagination and curiosity of the public and scientists alike. However, despite this popularity, relatively little is known about how these all-consuming giants evolve and shape the environment around them. NASA scientists are hoping to unravel some of these mysteries by observing an intermediate-mass black hole (IMBH) sitting 100 million light years away in the spiral arm of galaxy NGC 2276. Read More

Scientists find brightest night light circling impossibly huge black hole

By - February 27, 2015 4 Pictures
Astronomers have discovered a distant, massive and ancient black hole that calls into question current models for the early expansion of the universe. A team of scientists from China and Arizona spotted the brightest quasar from the early universe, named SDSS J0100+2802, centered on a black hole 12.8 billion light years away and as bright as 420 trillion suns.

Space telescopes uncover supermassive black hole winds

By - February 21, 2015 3 Pictures
Supermassive black holes are titanic oddities. Usually sited at the core of galaxies and various high-energy phenomena such as quasars, their mass can be anywhere from that of a hundred thousand to billions of suns. Now observations from NASA and ESA space telescopes are shedding light on the incredibly powerful cosmic winds they produce, which can have more energy than an entire galaxy. Read More

Quantum black hole study opens bridge to another universe

By - October 6, 2013 5 Pictures
Physicists have long thought that the singularities associated with gravity (like the inside of a black hole) should vanish in a quantum theory of gravity. It now appears that this may indeed be the case. Researchers in Uruguay and Louisiana have just published a description of a quantum black hole using loop quantum gravity in which the predictions of physics-ending singularities vanish, and are replaced by bridges to another universe.

Close encounter with a supermassive black hole

By - September 23, 2013 6 Pictures
As you read this, the eyes of the astrophysical world are focused on about one-trillionth of the sky, watching as the calm existence of G2, a three-Earth mass gas cloud near the galactic center, is viciously disrupted by a close encounter with Sagittarius A*, the galaxy's supermassive black hole. Careful observation of this rare event is expected to provide an enormous amount of information on the environment of the central light month (about 6,000 AU) immediately surrounding the black hole.
