Image 1 - Citizen Scientists Reveal Spitzer's Bubbly Milky Way
2012-03-08 04:25:33

A team of volunteers has pored over observations from NASA's Spitzer Space Telescope and discovered more than 5,000 "bubbles" in the disk of our Milky Way galaxy. Young, hot stars blow these bubbles into surrounding gas and dust, indicating areas of brand new star formation. Upwards of 35,000 "citizen scientists" sifted through the Spitzer infrared data as part of the online Milky Way Project to find these telltale bubbles. The volunteers have turned up 10 times as many bubbles as previous...

Image 1 - Milky Way's Black Hole Is Snacking On Asteroids

[ Watch the Video ] NASA said on Wednesday that the giant black hole at the center of our Milky Way galaxy may be consuming asteroids. They studied a cloud around the supermassive black hole known as Sagittarius A* (Sgr A) using NASA's Chandra X-ray Observatory. Chandra has detected X-ray flares about once a day from the black hole for the past several years.  The flares also have been seen in infrared data from ESO's Very Large Telescope in Chile. Researchers said asteroids...

[ Video 1 ] | [ Video 2 ] | [ Video 3 ] | The massive black hole at the center of our Milky Way Galaxy is destined to be invaded by a gas cloud, creating a violent encounter, according to astronomers. The supermassive black hole in the Milky Way is close enough for astronomers to study in detail, so the encounter could provide a unique chance for scientist to observe what until now has only been theorized. The astronomers plan to find out how a black hole eats up gas, dust and stars...

Hungry Milky Way Devours Galaxies

The Milky Way galaxy continues to devour its small neighboring dwarf galaxies and the evidence is spread out across the sky. A team of astronomers led by Sergey Koposov and Vasily Belokurov of Cambridge University recently discovered two streams of stars in the Southern Galactic hemisphere that were torn off the Sagittarius dwarf galaxy. This discovery came from analyzing data from the latest Sloan Digital Sky Survey (SDSS-III) and was announced in a paper released today that connects...

The region around the center of our Milky Way galaxy glows colorfully in this new version of an image taken by NASA's Spitzer Space Telescope. The data were previously released as part of a long, 120-degree view of the plane our galaxy (see this page). Now, data from the very center of that picture are being presented at a different contrast to better highlight this jam-packed region. In visible-light pictures, it is all but impossible to see the heart of our galaxy, but infrared light...

Observing the X-ray-bright gas in the halo of the Milky Way, ESA's XMM-Newton has gathered new data which favor a process involving fountains of hot gas in our Galaxy. Such a scenario, with the gas flowing from the galactic disc into the halo where it then condenses into cooler clouds and subsequently falls back to the disc, confirms the importance of supernova explosions in forging the evolution of the interstellar medium and of the entire Galaxy. The interstellar medium (ISM) in the Milky...

A dramatic new vista of the center of the Milky Way galaxy from NASA's Chandra X-ray Observatory exposes new levels of the complexity and intrigue in the Galactic center. The mosaic of 88 Chandra pointings represents a freeze-frame of the spectacle of stellar evolution, from bright young stars to black holes, in a crowded, hostile environment dominated by a central, supermassive black hole. Permeating the region is a diffuse haze of X-ray light from gas that has been heated to millions of...

Scientists have discovered a new class of black hole that stands at a mass of more than 500 times that of the Sun. An international team of astronomers detailed the new discovery found in a galaxy some 290 million light years from Earth in the journal Nature. The team used the European Space Agency's XMM-Newton X-ray observatory to find HLX-1 (Hyper-Luminous X-ray source 1) that could stand as the "missing link" between supermassive black holes "“ several million to several billion...

Using ESO's Very Large Telescope, astronomers have obtained one of the sharpest views ever of the Arches Cluster "” an extraordinary dense cluster of young stars near the supermassive black hole at the heart of the Milky Way. Despite the extreme conditions astronomers were surprised to find the same proportions of low- and high-mass young stars in the cluster as are found in more tranquil locations in our Milky Way. The massive Arches Cluster is a rather peculiar star cluster. It is...

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...
