UCLA -- UCLA astronomers can determine, for the first time, orbits of massive young stars located a few light months from the enormous black hole at the center of our Milky Way galaxy -- stars that hold an imprint of how they were born. The origin of young stars at the center of our galaxy has puzzled astronomers, but the orbits may be the key to unlocking the mystery, UCLA astronomy graduate student Jessica Lu reported today at the annual meeting of the American Astronomical Society in...

SDSS -- A huge but very faint structure, containing hundreds of thousands of stars spread over an area nearly 5,000 times the size of a full moon, has been discovered and mapped by astronomers of the Sloan Digital Sky Survey (SDSS-II). At an estimated distance of 30,000 light years (10 kiloparsecs) from Earth, the structure lies well within the confines of the Milky Way Galaxy. However, it does not follow any of Milky Way's three main components: a flattened disk of stars in which the sun...

WASHINGTON (Reuters) - The one-way journey from the heart of a galaxy into the oblivion of a black hole probably takes about 200,000 years, astronomers said on Monday. By tracking the death spiral of cosmic gas at the center of a galaxy called NGC1097, scientists figured that material moving at 110,000 miles an hour would still take eons to cross into a black hole. Black holes are drains in space that have gravitational pull so strong that nothing, not even light, can escape. Huge...

ESO -- Observations with Kueyen, one of the 8.2m telescopes composing the ESO Very Large Telescope (VLT), have led to the discovery of a short-lived massive star that is moving at a very high speed through the outer halo of the Milky Way galaxy and into intergalactic space. This finding could provide evidence for a previously unknown massive black hole in the heart of the Milky Way's closest neighbour, the Large Magellanic Cloud. The star, named HE 0437-5439, was discovered by the...

LONDON -- Chinese scientists said on Wednesday they had gathered evidence that shows a giant object in the center of our galaxy is a super-massive black hole. Zhi-Qiang Shen and researchers at the Shanghai Astronomical Observatory captured radio waves emitted just beyond the edge of the mysterious object, known as Sagittarius A, with a system of 10 radio telescopes spread across the United States. In a report in the science journal Nature they said it "provides strong evidence that Sgr A is a...

NASA -- The supermassive black hole at the center of the Milky Way has surprisingly helped spawn a new generation of stars, according to observations from NASA's Chandra X-ray Observatory. This novel mode of star formation may solve several mysteries about the supermassive black holes that reside at the centers of nearly all galaxies. "Massive black holes are usually known for violence and destruction," said Sergei Nayakshin of the University of Leicester, United Kingdom, and coauthor of a...

By Deborah Zabarenko WASHINGTON (Reuters) - Dozens of massive stars, destined for a short but brilliant life, were born less than a light-year away from the Milky Way's central black hole, one of the most hostile environments in our galaxy, astronomers reported on Thursday. On Earth, this might be a bit like setting up a maternity ward on the side of an active volcano. But researchers using the Chandra X-ray Observatory and other instruments believe there is a safe zone around black...

Cambridge, MA -- Common wisdom holds that we can never see a black hole because nothing can escape it - not even light. Fortunately, black holes aren't completely black. As gas is pulled into a black hole by its strong gravitational force, the gas heats up and radiates. That radiation can be used to illuminate the black hole and paint its profile. Within a few years, astronomers believe they will be able to peer close to the horizon of the black hole at the center of the Milky Way. Already,...

Chandra -- A swarm of 10,000 or more black holes may be orbiting the Milky Way's supermassive black hole, according to new results from NASA's Chandra X-ray Observatory. This would represent the highest concentration of black holes anywhere in the Galaxy. These relatively small, stellar-mass black holes, along with neutron stars, appear to have migrated into the Galactic Center over the course of several billion years. Such a dense stellar graveyard has been predicted for years, and this...

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...
