The Mysterious Bubbles at the Center of the Milky Way

  The Mysterious Bubbles at the Center of the Milky Way Astronomers have found radio-emitting structures jutting out from our galaxy's black hole.But the mystery filament kept showing up, and soon Yusef-Zadeh found others. What the astronomer had mistaken for an imperfection turned out to be an entire population of cosmic structures at the heart of the galaxy.

Mammoth galaxies generally host supermassive black holes , monster black holes with about 100 million times more mass than the sun, in their center . Previous studies have examined the galaxy in great detail and found the two supermassive black holes pumping out a ton of light -- but the new

Catching two supermassive black holes sharing close quarters isn’t that unusual . But spotting three jockeying for position is quite bizarre. In the study, an international team of astronomers identified three supermassive black holes lurking near the center of galaxy NGC 6240, which has been

a star in the middle of the night: NGC 6240 was birthed when two galaxies collided. NASA/ESA/the Hubble Heritage (STScI/AURA)-ESA/Hubble Collaboration/A.

NASA/ESA/the Hubble Heritage (STScI/AURA)-ESA/Hubble Collaboration/A. Evans (University of Virginia, Charlottesville/NRAO/Stony Brook University) Huge, spiral galaxies like our home galaxy -- the Milky Way -- look like beautiful, starry pinwheels, but not all galaxies are formed with such artistic sensibilities. Take, for example, NGC 6240: An irregular galaxy approximately 300 million light-years from Earth that looks like a smashed egg and was formed when a pair of galaxies collided with one another.

Astronomers have long believed that collision resulted in NGC 6240 housing two supermassive black holes, but new research suggests they were wrong: NGC 6240 has three supermassive black holes at its galactic center.

A Dazzling Quarter Century of Exoplanet Discovery

  A Dazzling Quarter Century of Exoplanet Discovery The next time the Nobel Prize recognizes exoplanet science, it could be for the detection of signs of life on another world.Michel Mayor and Didier Queloz were awarded the prize in physics today for finding 51 Pegasi b, the first known planet orbiting another sun-like star. (They share the prize with the physicist James Peebles, for his theoretical work on the origins and nature of the universe.

For the first time, scientists found a third supermassive black hole at a galaxy ’s center . Two’s company, three ’s a crowd for galaxy NGC 6240!

When galaxies collide, it means their supermassive black holes at the center of each galaxy collide as well. Recently, astronomers have detected a triple

The first-of-its-kind finding, published in the journal Astronomy & Astrophysics in October, suggests that NGC 6240 may have been formed by a collision between three galaxies. Using the Very Large Telescope (VLT) in Chile, the research team were able to examine the motion and mass of the black holes at the center of NGC 6240.

Mammoth galaxies generally host supermassive black holes, monster black holes with about 100 million times more mass than the sun, in their center. Those black holes keep galaxies like the Milky Way in constant motion, spinning billions of stars and planets around the galactic center, like a delightful cosmic carousel. NGC 6240 is a bit different.

It's huge, has an unusual shape and is incredibly bright. Astronomers suspect its intense light comes from the huge amount of dust, intense star formation and supermassive black holes that make the galaxy up. Previous studies have examined the galaxy in great detail and found the two supermassive black holes pumping out a ton of light -- but the new work, by researchers at the University of Göttingen and University of Pottsdam in Germany, shows an extra cosmic beast lurking in the galaxy.

Could life survive on an Earth-like planet orbiting a black hole?

  Could life survive on an Earth-like planet orbiting a black hole? Jeremy Schnittman, a research astrophysicist at NASA, tries to answer this question.Black hole, this is neutron star. Neutron star, meet black hole. You guys are going to get along just fine...

Astronomers from UCLA's Galactic Center Orbits Initiative have discovered a new class of bizarre objects at the Orbits of the G objects at the center of our galaxy , with the supermassive black hole indicated Ghez's research group identified an unusual object at the center of our galaxy in 2005

A supermassive black hole (SMBH) is the largest type of black hole , on the order of hundreds of thousands to billions of solar masses (M?), and is found in

"Through our observations with extremely high spatial resolution we were able to show that the interacting galaxy system NGC 6240 hosts not two -- as previously assumed -- but three supermassive black holes in its centre," said Wolfram Kollatschny, an astronomer at the University of Göttingen and lead author on the study.

Astronomers have a decent idea about how some galaxies form and evolve over time. For instance, the Milky Way is also thought to have devoured a smaller galaxy billions of years ago, which gives rise to two distinct populations of stars showing up around its outer edges. However, for massive galaxies like NGC 6240, the formation and evolution has been a bit of a mystery.

According to Peter Weilbacher, a co-author of the study from the Leibniz Institute for Astrophysics at Potsdam University, this is the first indication of simultaneous merging processes of several galaxies and their central black holes.
