Hubble images some of galaxy's dimmest stars
Using the Hubble Space Telescope, astronomers have imaged some of the galaxy's oldest and dimmest stars, offering a rare experimental glimpse of two mysterious star types - tiny, slow burners less than one-tenth the size of our sun and once giant stars that still glow more than 10 billion years after their deaths. view more (2006-08-21)
Resolving a galactic mystery
An extremely deep Chandra X-ray Observatory image of a region near the center of our Galaxy has resolved a long-standing mystery about an X-ray glow along the plane of the Galaxy. view more (2009-04-30)
Hubble sees faintest stars in a globular cluster
The NASA/ESA Hubble Space Telescope has uncovered what astronomers are reporting as the dimmest stars ever seen in any globular star cluster. view more (2006-08-21)

Call 2 of Eureka cluster project CELTIC issued
Eureka cluster project CELTIC has launched its second call for new project proposals. The deadline for submission of proposal outlines is 28 April 2004. In the second phase from 21 June to 6 October 2004, full project proposals of the selected project outlines will be submitted. The start of the projects is envisaged for early 2005. The overall... view more... (2004-02-20)
Clash of clusters provides new dark matter clue
A powerful collision between galaxy clusters has been captured by the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory. This clash of clusters provides striking evidence for dark matter and insight into its properties. view more (2008-08-28)
Astronomers discover stars in early galaxies had a need for speed
A team of astronomers has measured the motions of stars in a very distant galaxy for the first time and discovered they are whizzing around at astonishingly high speeds-about one million miles per hour, or twice the speed at which the Sun circles our own Milky Way galaxy. view more (2009-08-07)
NASA's Swift Sees Double Supernova in Galaxy
In just the past six weeks, two supernovae have flared up in an obscure galaxy in the constellation Hercules. Never before have astronomers observed two of these powerful stellar explosions occurring in the same galaxy so close together in time. view more (2007-06-27)
Chandra independently determines Hubble constant
A critically important number that specifies the expansion rate of the Universe, the so-called Hubble constant, has been independently determined using NASA's Chandra X-ray Observatory. view more (2006-08-10)
New treatment effective for most severe kind of headache
A nasal spray is safe and effective at rapidly treating cluster headaches, which are considered to be the most painful kind of headache with few treatment options. view more (2007-08-28)
Astronomers discover link between supermassive black holes and galaxy formation
A pair of astronomers from Texas and Germany have used a telescope at The University of Texas at Austin's McDonald Observatory together with Hubble Space Telescope and many other telescopes around the world to uncover new evidence that the largest, most massive galaxies in the universe and the supermassive black holes at their hearts grew together... view more...

Monster galaxy pileup sighted
Four galaxies are slamming into each other and kicking up billions of stars in one of the largest cosmic smash-ups ever observed. view more (2007-08-07)
NASA's Fermi Finds Gamma-ray Galaxy Surprises
Back in June 1991, just before the launch of NASA's Compton Gamma-Ray Observatory, astronomers knew of gamma rays from exactly one galaxy beyond our own. view more (2009-07-15)
Second Cluster pair soar into the skies above Baikonur
At 17.13 local time (13.13 CEST) today, the second pair of Cluster spacecraft lifted off from pad 6 at Baikonur Cosmodrome aboard a Soyuz-Fregat launch vehicle. On a scorching summer afternoon, with temperatures well over 40°C, conditions were perfect for this second act in the Cluster launch drama. Topped by a giant fairing emblazoned with a... view more...

Astronomers search for orphan stars using newly upgraded telescope
Using new charge coupled device (CCD) instrumentation, Case Western Reserve University astronomers can now view the night sky wider and deeper than before. view more (2008-05-20)
Integral identifies supernova rate for Milky Way
Using ESA's Integral observatory, an international team of researchers has been able to confirm the production of radioactive aluminium (Al 26) in massive stars and supernovae throughout our galaxy and determine the rate of supernovae-one of its key parameters. view more (2006-01-09)
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)
Hubble celebrates 19th anniversary with fountain of youth
NASA/ESA Hubble Space Telescope's 19 years of success, the orbiting telescope has photographed a peculiar system of galaxies known as Arp 194. This interacting group contains several galaxies along with a "cosmic fountain" of stars, gas and dust that stretches over 100 000 light years. view more (2009-04-22)
Queen's physicist unlocking the mysteries of neighbouring galaxies
An international team of astronomers, including Queen's University physicist Larry Widrow, have uncovered evidence of a nearby cosmic encounter. view more (2009-09-08)
The NASA/ESA Hubble Space Telescope is back in business
Just a couple of days after the orbiting observatory was brought back online, Hubble aimed its prime working camera, the Wide Field Planetary Camera 2 (WFPC2), at a particularly intriguing target, a pair of gravitationally interacting galaxies called Arp 147. view more (2008-10-31)
