Supermassive black hole

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.  Read More

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

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

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

Astronomers from the University of Utah, using the Gemini North telescope on Hawaii’s Mauna Kea and images captured by the Hubble Space Telescope, have discovered a dwarf galaxy that is the smallest ever recorded with a supermassive black hole at its center. The galaxy, M60-UCD1, has been found to contain a black hole with a mass equivalent to 21 million times that of our own sun and whose presence may suggest that such enormous black holes could be more common than previously thought.  Read More

As the US prepares for 4th of July fireworks here on Earth, a nearby spiral galaxy similar to our Milky Way is putting on a pyrotechnics display of its own. The galaxy, NGC 4258 (also known as Messier 106 or M 106), is ejecting gas and high-energy particles in a spectacular display of power that is rippling across the face of the galaxy with shock waves of stellar energy.  Read More

A fresh analysis of data collected by NASA's WISE telescope has cast doubt on the widely accepted unified model for the composition of black holes. The study examined 170,000 supermassive black holes, and will require scientists to present new theories on the structure of these stellar giants.  Read More

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.  Read More
