Flickering Quasars --"Signal the Collision of Supermassive Black Holes"
Earlier this year, astronomers discovered what appeared to be a pair of supermassive black holes circling toward a collision so powerful it would send a burst of gravitational waves surging through the fabric of space-time itself. Astronomers at Columbia University...

Milky Way’s Black Hole Shows Signs of Increased Chatter
Three orbiting X-ray space telescopes have detected an increased rate of X-ray flares from the usually quiet giant black hole at the center of our Milky Way galaxy after new long-term monitoring.

Too big for its boots: black hole is 30 times expected size
The central supermassive black hole of a recently discovered galaxy is far larger than should be possible, according to current theories of galactic evolution. New work, carried out by astronomers at Keele University and the University of Central Lancashire, shows that the black hole is much more massive than it should be, compared to the mass of the galaxy around it. The scientists publish their results in a paper...

A 'dead' galaxy full of dark matter is lurking close to home
At the edge of the Milky Way, there's a small galaxy called Triangulum II. It has just 1,000 stars, compared to the 100 billion estimated in our own galaxy, and its days of star formation are over, leaving it "dead." But Triangulum II may have a dark secret - one that makes it the most interesting ghost town in space.

Scientists get first glimpse of black hole eating star, ejecting high-speed flare
An international team of astrophysicists led by a Johns Hopkins University scientist has for the first time witnessed a star being swallowed by a black hole and ejecting a flare of matter moving at nearly the speed of light. The finding reported Thursday in the journal Science tracks the star—about the size of our sun—as it shifts from its customary path, slips into the gravitational pull of a supermassive black hole and is sucked in, said Sjoert van Velzen, a Hubble fellow at Johns Hopkins.

Dazzling diamonds
Single stars are often overlooked in favour of their larger cosmic cousins — but when they join forces, they create truly breathtaking scenes to rival even the most glowing of nebulae or swirling of galaxies. This NASA/ESA Hubble Space Telescope image features the star cluster Trumpler 14. One of the largest gatherings of hot, massive and bright stars in the Milky Way, this cluster houses some of the most luminous stars in our entire galaxy.

The huge gas cloud flying towards our galaxy could create 200 million new stars
A giant gas cloud hurtling towards the Milky Way could form two million new stars when it finally collides with our galaxy. The discovery was made after astronomers managed to figure out the chemical composition of the Smith Cloud, a huge formation of gas approaching the edges of the Milky Way at a speed of around 193 miles per second.

Tarantula Nebula: Hubble spots nine 'monster' stars with masses 100 times that of the Sun
The Hubble Space Telescope has identified nine monster stars in outer space, all with a mass of over 100 times that of the Sun. The stars are part of the cluster R136, and have become the largest group of massive stars ever found. The star cluster is located 170,000 light years from Earth, and the findings will help astronomers learn about the origin of giant stars. The report was published in the Monthly Notices Of The Royal Astronomical Society.

Faintest early-universe galaxy ever, detected and confirmed
An international team of scientists has detected and confirmed the faintest early-Universe galaxy ever using the W. M. Keck Observatory on the summit on Maunakea, Hawaii. In addition to using the world's most powerful telescope, the team relied on gravitational lensing to see the incredibly faint object born just after the Big Bang. The results are being published in The Astrophysical Journal Letters today.

Galaxy Cluster Spotted in Early Universe
Astronomers discover a vast collection of young galaxies from the early universe.Astronomers have discovered a collection of young galaxies, stretching more than 489 million by 244 million light-years whose light has taken 12 billion years to reach Earth, one of the most massive structures known at that distance - See more at: http://www.skyandtelescope.com/astronomy-news/galaxy-cluster-spotted-in-early-universe/?
