Swift Makes Best-ever Ultraviolet Portrait of Andromeda Galaxy
In a break from its usual task of searching for distant cosmic explosions, NASA's Swift satellite has acquired the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet. view more (2009-09-17)
NIST math technique opens clearer window on universe
A fast, efficient image enhancement technique developed at the National Institute of Standards and Technology (NIST) and originally applied to improving monochrome microscope images has proved itself equally effective at the other end of the scale- sharpening details on color images of distant galaxies produced by the Hubble Space Telescope. view more (2006-12-11)
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)
Significant new method developed for characterizing density wave features
In a paper published in The Astronomical Journal (133:2584-2606, June 2007) Dr. Xiaolei Zhang, of the Naval Research Laboratory, and Dr. Ronald J. Buta, of the University of Alabama, report that they have developed an accurate and widely-applicable method for characterizing density wave features in galaxies. view more (2007-07-10)
Looking further into the Universe
How can the Universe be studied? There is no way to affect a research object of infinite dimensions. It means that the research can only be carried out via observations, employing all methods available. To this end scientists have been inventing more and more powerful telescopes which would enable them to examine closely remote spots of the... view more... (2002-04-19)
NASA Telescope Reveals Nearby Galaxy's Invisible Arms
A new image from NASA's Galaxy Evolution Explorer shows that a galaxy once thought to be rather plain and old is actually endowed with a gorgeous set of young spiral arms. view more (2005-07-25)
Black hole in search of a home
The detection of a super massive black hole without a massive host galaxy is the surprising result from a large Hubble and VLT study of quasars. view more (2005-09-15)
Black hole found in enigmatic Omega Centauri
A new discovery has resolved some of the mystery surrounding Omega Centauri, the largest and brightest globular cluster in the sky. Images obtained with the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope and data obtained by the GMOS spectrograph on the Gemini South telescope in Chile show that Omega Centauri appears to... view more...

University of Minnesota astronomers find gaping hole in the Universe
University of Minnesota astronomers have found an enormous hole in the Universe, nearly a billion light-years across, empty of both normal matter such as stars, galaxies and gas, as well as the mysterious, unseen "dark matter." While earlier studies have shown holes, or voids, in the large-scale structure of the Universe, this new... view more... (2007-08-24)
Colors of Quasars Reveal a Dusty Universe
The vast expanses of intergalactic space appear to be filled with a haze of tiny, smoke-like "dust" particles that dim the light from distant objects and subtly change their colors, according to a team of astronomers from the Sloan Digital Sky Survey (SDSS-II). view more (2009-02-26)
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)
Heavy Stars Thrive among Heavy Elements
VLT Observes Wolf-Rayet Stars in Virgo Cluster Galaxies [1] Do very massive stars form in metal-rich regions of the Universe and in the nuclei of galaxies ? Or does "heavy element poisoning" stop stellar growth at an early stage, before young stars reach the "heavyweight class"? What may at the first glance appear as a question for specialists... view more... (2002-08-23)
NASA's Fermi Telescope Reveals Best-Ever View of Gamma-Ray Sky
A new map combining nearly three months of data from NASA's Fermi Gamma-ray Space Telescope is giving astronomers an unprecedented look at the high-energy cosmos. To Fermi's eyes, the universe is ablaze with gamma rays from sources ranging from within the solar system to galaxies billions of light-years away. view more (2009-03-12)
X-Ray Vision Of Violence In Interacting Galaxy Clusters
ROYAL ASTRONOMICAL SOCIETY PRESS NOTICE: Ongoing research by an international team of astronomers is providing new insights into cataclysmic cosmic collisions between galaxy clusters. view more (2005-03-31)
Hubble repair mission carrying $70 million CU-Boulder instrument on track for May 11 launch
A $70 million instrument designed by the University of Colorado at Boulder to probe the evolution of galaxies, stars and intergalactic matter from its perch on the orbiting Hubble Space Telescope is on schedule for its slated May 11 launch from Kennedy Space Center in Florida aboard NASA's space shuttle Atlantis. view more (2009-05-08)
Young supernova remnants not dusty enough, according to UC Berkeley astronomers
One of the youngest supernova remnants known, a glowing red ball of dust created by the explosion 1,000 years ago of a supermassive star in a nearby galaxy, the Small Magellanic Cloud, exhibits the same problem as exploding stars in our own galaxy: too little dust. view more (2006-06-07)
Seeing the Cosmos Through
NASA's Spitzer Space Telescope has taken its first shots of the cosmos since warming up and starting its second career. The infrared telescope ran out of coolant on May 15, 2009, more than five-and-half-years after launch, and has since warmed to a still-frosty 30 Kelvin (about minus 406 Fahrenheit). view more (2009-08-06)
The Virgo Cluster of Galaxies in the Making
An international team of astronomers [1] has succeeded in measuring with high precision the velocities of a large number of planetary nebulae [2] in the intergalactic space within the Virgo Cluster of galaxies. For this they used the highly efficient FLAMES spectrograph [3] on the ESO Very Large Telescope at the Paranal Observatory (Chile). view more (2004-10-29)
UBC, U of T team helps solve mystery of starlight's origins
Scientists from the University of Toronto and the University of British Columbia have helped unveil the birthplaces of ancient stars using a two-tonne telescope carried by a balloon the size of a 33-storey building. view more (2009-04-09)
