Iowa State astrophysicist helps map the Milky Way's four spiral arms
Iowa State University's Martin Pohl is part of a research team that has developed the first complete map of the Milky Way galaxy's spiral arms. view more (2009-01-05)
Cosmic dance helps galaxies lose weight
A study published this week in the journal Nature offers an explanation for the origin of dwarf spheroidal galaxies. The research may settle an outstanding puzzle in understanding galaxy formation. view more (2009-07-30)
A Very Massive Stellar Black Hole in the Milky Way Galaxy
VLT ISAAC Uncovers an Enigmatic Microquasar view more (2001-11-27)
Herschel Space Telescope's SPIRE instrument package makes first-light observations
A scientific instrument package developed in part by the University of Colorado at Boulder for the $2.2 billion orbiting Herschel Space Observatory that was launched in May by the European Space Agency has made its first successful observations, targeting two star-forming galaxies near the Milky Way. view more (2009-07-13)
Galactic survey reveals a new look for the Milky Way
With the help of NASA's Spitzer Space Telescope, astronomers have conducted the most comprehensive structural analysis of our galaxy and have found tantalizing new evidence that the Milky Way is much different from your ordinary spiral galaxy. view more (2005-08-17)
Ultrafast star escapes black hole
Galactic nuclei are the cores of galaxies, groups of thousands to millions of stars that are held together by gravity. As stars in the nucleus are so close together, interactions readily occur. view more (2006-10-05)
Astronomers report mysterious giant star clusters
An international team of astronomers reported evidence for the formation of mysterious "super star clusters" Jan. 9 at the annual meeting of the American Astronomical Society in Washington, D.C. view more (2006-01-11)
How Old is the Universe?
Most astronomers would agree that the age of the Universe - the time elapsed since the "Big Bang" - is one of the "holy grails of cosmology". Despite great efforts during recent years, the various estimates of this basic number have resulted in rather diverse values. When derived from current cosmological models, it depends on a number of... view more... (2001-02-06)
The Milky Way's tiny but tough galactic neighbor
In the new ESO image, Barnard's Galaxy glows beneath a sea of foreground stars in the direction of the constellation of Sagittarius (the Archer). view more (2009-10-14)
THE MAKING OF THE MILKY WAY HALO
The brightest objects in the halo are the globular clusters. They are large groupings of stars that were formed together in the very early evolutionary phases of the Milky Way, some 12,000 - 14,000 million years ago. This happened soon after the moment when the first structures emerged in the large cloud of primordial hydrogen in which our Galaxy... view more... (1999-02-18)
NASA's Swift satellite images a galaxy ablaze with starbirth
Combining 39 individual frames taken over 11 hours of exposure time, NASA astronomers have created this ultraviolet mosaic of the nearby "Triangulum Galaxy." view more (2008-02-26)
Rogue Black Holes May Roam the Milky Way
It sounds like the plot of a sci-fi movie: rogue black holes roaming our galaxy, threatening to swallow anything that gets too close. In fact, new calculations by Ryan O'Leary and Avi Loeb (Harvard-Smithsonian Center for Astrophysics) suggest that hundreds of massive black holes, left over from the galaxy-building days of the early universe, may... view more...

Magellanic gemstones in the southern sky
Hubble has captured the most detailed images to date of the open star clusters NGC 265 and NGC 290 in the Small Magellanic Cloud-two sparkling sets of gemstones in the southern sky. view more (2006-04-18)
Intense heat killed the Universe's would-be galaxies, researchers say
Our Milky Way galaxy only survived because it was already immersed in a large clump of dark matter which trapped gases inside it. view more (2009-07-01)
Physicists find evidence for highest energy photons ever detected from Milky Way's equator
Physicists at nearly a dozen research institutions, including New York University, have discovered evidence for very high energy gamma rays emitting from the Milky Way, marking the highest energies ever detected from the galactic equator. view more (2005-12-14)
Star on a Hubble diet
How heavy can a star be? This conundrum has haunted astronomers for decades. Theory indicates that there should be an upper stellar mass limit somewhere between 120 and 300 solar masses. Even though heavy stars are very bright, measurements of their masses can be complicated. view more (2006-12-12)
Another bar in the Bulge
Using 2MASS data, Christophe Alard (astronomer at Paris Observatory) has reconstructed a map of the projected density of the old stellar population of the Galactic Bulge region. By making a combination of the H and K photometric bands, it is possible to overcome the effect of reddening, and thus penetrate the inner structure of the Galactic Bulge. view more (2001-11-21)
A New 3-D Animated Map Of Our Cosmic Hometown
For the first time, we now have a three-dimensional map of our closest cosmic neighbourhood which shows not only how our nearest neighbour stars are distributed today - it also shows precisely how fast each of them moves, and in which direction. Astronomers have measured the velocities of many thousands of stars and computed both where they were... view more... (2004-04-06)
NRL scientists detect 'milky sea' phenomena
Scientists at the Naval Research Laboratory's Marine Meteorology Division in Monterey, CA, (NRL-Monterey), working with researchers from Monterey Bay Aquarium Research Institute and the National Geophysical Data Center, presented the first satellite detection of a phenomenon known as the "milky sea." view more (2005-10-18)
Red sky at night -- astronomers delight
A collaboration of over 50 astronomers, The IPHAS consortium, led from the UK, with partners in Europe, USA, Australia, has released the first comprehensive optical digital survey of our own Milky Way. view more (2007-12-11)
