newly discovered planet in binary system
2014-07-04 04:31:19

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have located a new terrestrial planet in a binary star system located roughly 3,000 light-years from Earth, according to new research appearing in the July 4 edition of the journal Science. Ohio State University professor Andrew Gould and four international teams of scientists used the technique of gravitational microlensing to discover the new planet, which is roughly twice the mass of Earth and orbits one of its...

Magnetic Fields Counteract The Forces Of Supermassive Black Holes
2014-06-05 11:37:47

Brett Smith for redOrbit.com - Your Universe Online A supermassive black hole sits at the center of most galaxies and a new study published in the journal Nature has found that super-powerful magnetic fields can have influence near and even counteract the forces of these black holes. "This paper for the first time systematically measures the strength of magnetic fields near black holes," said study author Alexander Tchekhovskoy, an astronomer at the University of California, Berkeley....

simulation of the gas cloud G2's encounter with the supermassive black hole Sgr A*

Megan Fellman, Northwestern University Gas cloud’s fate could reveal information on growth of supermassive black holes Right now a doomed gas cloud is edging ever closer to the supermassive black hole at the center of our Milky Way galaxy. These black holes feed on gas and dust all the time, but astronomers rarely get to see mealtime in action. Northwestern University’s Daryl Haggard has been closely watching the little cloud, called G2, and the black hole, called Sgr A*, as part...

Swift Sees X-ray Action In Milky Way's Center

[ Watch the Video: Swift Sees Changes in the Milky Way 2006 – 2013 ] Lee Rannals for redOrbit.com - Your Universe Online Scientists have discovered a rare celestial entity that could help test predictions of Albert Einstein’s theory of general relativity. A team at the annual meeting of the American Astronomical Society in National Harbor, Maryland, explained how images obtained through NASA’s Swift spacecraft could help decipher the physical nature of X-ray flares and enable...

Milky Way's Black Hole Shows Off It's Jet Of High-Energy Particles
2013-11-21 10:21:13

Brett Smith for redOrbit.com - Your Universe Online Many supermassive black holes emit a jet of high-energy particles as a byproduct of engulfing large quantities of mass and energy, and NASA researchers have just discovered that the supermassive black hole at the center of the Milky Way is no different. Using observations from NASA's Chandra X-ray Observatory and the National Science Foundation's Very Large Array (VLA) radio telescope, a team of Chinese and American astrophysicists...

Light Echoes From The Black Hole At The Heart Of The Milky Way

[ Watch the Video: Time-Lapse of Supermassive Black Hole Sagittarius A* ] April Flowers for redOrbit.com - Your Universe Online During the last few hundred years, the dim region very close to the supermassive black hole near the center of the Milky Way has flared up with at least two luminous outbursts, according to a team of researchers using NASA's Chandra X-ray Observatory. A new study of rapid variations in the X-ray emissions from gas clouds surrounding Sagittarius A* (Sgr A*) -...

Sleeping Supermassive Black Holes Can Have Periods Of Intense Flare-Ups
2013-09-24 14:01:00

[ Watch the Video: Intense Flare-Ups In Supermassive Black Holes ] Brett Smith for redOrbit.com - Your Universe Online Around 2 million years ago, the supermassive black hole at the center of our galaxy erupted in a blaze of glory big enough to leave a residual glow that can still be seen today, according to an upcoming paper to be published in The Astrophysical Journal. The astronomers who conducted the study said their findings support the theory that black holes can ‘awaken from...

Researchers Explain Why Supermassive Black Holes Eat Less Material Than Expected
2013-08-30 08:51:11

[ Watch the Video: Black Hole On A Diet ] April Flowers for redOrbit.com - Your Universe Online A long-standing mystery concerning supermassive black holes (SMBH) at the center of galaxies has been solved by a team of astronomers using NASA’s super-sensitive Chandra X-ray Space Telescope. The team, led by Q. Daniel Wang at the University of Massachusetts Amherst, investigated why these SMBHs have such a low accretion rate, or rather, why they swallow very little of the cosmic gases...

Trifid Nebula -- Discovered by Charles Messier in 1764. Charles Messier discovered this object on June 5, 1764, and described it as a cluster of stars of 8th to 9th magnitude, enveloped in nebulosity. The Trifid Nebula M20 is famous for its three-lobed appearance. This may have caused William Herschel, who normally carefully avoided to number Messier's objects in his catalog, to assign four different numbers to parts of this nebula: H IV.41 (cataloged May 26, 1786) and H V.10, H V.11,...

Lagoon Nebula -- The Lagoon Nebula was discovered by Le Gentil in 1747. As often for diffuse nebulae, the cluster of young stars which has formed from the nebula's material was discovered first. In this case the young open cluster NGC 6530 in the Eastern half of M8 was discovered by Flamsteed about 1680, and again seen by De Ch'seaux in 1746, before Le Gentil found the nebula in 1747. Abbe Nicholas Louis de la Caille has cataloged it in his 1751-52 compilation as Lacaille III.14....
