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...

Scientists Create The First 360-Degree Virtual Map Of The Milky Way
2014-03-21 07:25:44

[ Watch the Video: 360-Degree View of the Milky Way ] Lawrence LeBlond for redOrbit.com - Your Universe Online NASA’s Spitzer Space Telescope has been busy studying stars, asteroids, galaxies and other outer space objects over the past 10 years and a University of Wisconsin team of scientists has now used more than two million images produced by Spitzer to create a virtual 360-degree mosaic of our Milky Way. The team presented the new interactive map Thursday at the TEDActive 2014...

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

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...

WASHINGTON, Nov. 20, 2013 /PRNewswire-USNewswire/ -- Astronomers have long sought strong evidence that Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, is producing a jet of high-energy particles. Finally they have found it, in new results from NASA's Chandra X-ray Observatory and the National Science Foundation's Very Large Array (VLA) radio telescope.

[ Watch the Video: Is There A Supernova In Your Future? ] Brett Smith for redOrbit.com - Your Universe Online A supernova is one of the most brilliant events to take place in the universe and astronomers at The Ohio State University have determined we will see one in the Milky Way Galaxy within the next 50 years. While the odds of actually seeing a star explode with the naked eye is very low during that time span, a supernova would be visible to specialized telescopes in the form of...

Legacy Of The X-ray Universe Preserved With Chandra Data Archive
2013-10-30 07:05:30

NASA Every year, October is designated as American Archive Month. While many people may think “archive” means only dusty books and letters, there are, in fact, many other types of important archives. This includes the use of archives for major telescopes and observatories like NASA’s Chandra X-ray Observatory. The Chandra Data Archive (CDA) plays a central role in the mission by enabling the astronomical community – as well as the general public – access to data collected by...

Light Echoes From The Black Hole At The Heart Of The Milky Way
2013-10-25 05:25:40

[ 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...

Milky Way Galaxy -- The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Galaxia (gala, galactos means "milk")) is a hazy band of white light across the night sky formed by billions of stars in the disc of our galaxy. The Milky Way appears brightest in the direction of Sagittarius, where the galactic centre lies. Relative to the celestial equator, the Milky Way passes as far north as the constellation of Cassiopeia and as far south as the constellation of...
