Supermassive black hole

Space

Black hole weighing 17 billion suns found in "cosmic backwater"

Black holes are a bit like celebrities — the larger they are, the more activity they have swirling about them. It came as some surprise then, when two NASA telescopes spied a supermassive black hole in a relatively quiet neighborhood of the universe. The gravity gobbler has the weight of 18 billion of our suns and is found in a giant elliptical galaxy that should have a much more impressive bulge of stars near its center for a black hole of that size.Read More

Astronomers trace the magnetic field of the supermassive black hole at the center of our galaxy

A team of astronomers has successfully detected magnetic fields present around the event horizon of the supermassive black hole at the center of our galaxy. It is thought that these magnetic fields are the driving factor behind a mechanism that sends intense pulses of galaxy sculpting radiation blasting thousands of light-years into space from the event horizon of a spinning black hole.Read More

Orbital telescopes detect increased activity from the supermassive black hole at the heart of the Milky Way

Three space-based observatories appear to have picked up an unusual increase in activity from the supermassive black hole located at the center of our galaxy. According to the data, the black hole known as Sagittarius A* (Sgr A*), which has a mass of roughly 4 million times our Sun, is throwing out ten times the usual amount of bright X-ray flares.Read More

WISE discovers brightest galaxy in the universe

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.Read More

Earth-sized virtual telescope to study supermassive black hole at center of Milky Way

In astronomy, much like many other other aspects of life, bigger is better. Taking this adage to heart, astronomers at the University of Arizona are helping to build a virtual radio telescope the size of the Earth itself. With a resolution factor more than a thousand times greater than that of the Hubble Space Telescope, the new Event Horizon Telescope (EHT) will be used to study in fine detail the supermassive black hole at the center of our Milky Way.

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

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
