Astronomers Find Newborn Stars Near Supermassive Black Hole

March 27, 2017

A star being consumed by a black hole may seem quite common.  But, news of stars being formed alongside a black hole could be something to notice! But that’s just what a UK-led group of astronomers say they recently discovered. While they were studying the ongoing collision of two galaxies, known jointly as IRAS F23128-5919, […]

Black Hole Awakens; Mozart Lowers B.P.; Baby Planet Found

Scientists Observe Awakening of Dormant Super Massive Black Hole Scientists say that, in the known universe, about 90% of the biggest black holes are dormant, which means they aren’t ravenously devouring matter. Because they’re dormant these black holes aren’t pumping out radiation or any kind of light. But all it takes is for a star […]

Astronomers Precisely Measure Black Hole Mass A group of astronomers have been able to determine the precise mass of a distant black hole in the center of an enormous elliptical galaxy 73 million light years away. The galaxy is called NGC 1332 and is located in the direction of the southern constellation Eridanus. To measure […]

A Blast of Gamma Rays from Halfway Across the Universe Detected

December 16, 2015

Back in April 2015, a surge of high-powered gamma rays from half-way across the universe crashed into Earth’s atmosphere. But, according to the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, the burst of gamma rays didn’t put any of us in danger and produced no noticeable effects since the high-energy rays are blocked by Earth’s atmosphere. Astronomers, using […]

Slumbering Giant Black Hole Awakes After 26 Years

June 27, 2015

Some 8,000 light years from Earth, in the constellation Cygnus, a binary system known as V404 Cygni has come to life for the first time in 26 years. While most binary systems consist of two stars orbiting a common center of mass, V404 Cygni is made up of a black hole and a star that […]
