Erie County home to plant never before recorded in Pa.
Western Pennsylvania Conservancy (WPC) scientists have discovered a plant in Erie County that has never been recorded in Pennsylvania. view more (2009-09-28)
Plutoid chosen as name for Solar System objects like Pluto
Almost two years after the International Astronomical Union (IAU) General Assembly introduced the category of dwarf planets, the IAU, as promised, has decided on a name for transneptunian dwarf planets similar to Pluto. view more (2008-06-12)
100 Photographs in the Blink of an Eye
Scientists from the Universities of Sheffield and Southampton in collaboration with the UK Astronomy Technology Centre at the Royal Observatory, Edinburgh have just opened a new window on the Universe by commissioning ULTRACAM - an ultra-fast camera which can take up to 1000 pictures a second in three different colours simultaneously. The camera,... view more... (2002-07-24)
Dusty old star offers window to our future, astronomers report
Astronomers have glimpsed dusty debris around an essentially dead star where gravity and radiation should have long ago removed any sign of dust - a discovery that may provide insights into our own solar system's eventual demise several billion years from now. view more (2005-09-09)
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)
Scientists snap images of first brown dwarf in planetary system
Scientists using NASA's Spitzer Space Telescope have discovered and directly imaged a small brown dwarf star, 50 times the mass of Jupiter, orbiting with a planet around a Sun-like star. view more (2006-09-19)
Nuclear explosion on a dead star - astronomers probe aftermath
A team of astronomers from the UK and Germany have found that a nuclear explosion on the surface of a star 5,000 light years from Earth resulted in a blast wave moving at over 1,700 km per second (one thousand miles per second or almost four million miles per hour!). view more (2006-07-20)
Search for Sirius companions
Many direct or indirect observations have suggested the existence of a second companion (in addition of the white dwarf Sirius-B) around the brilliant star Sirius-A. The presence of a second faint star could in particular explain a change of color of Sirius, as suggested by historical texts. A team of astronomers of the CEA (Service of... view more...

New recipe for dwarf galaxies: Start with leftover gas
There is more than one way to make a dwarf galaxy, and NASA's Galaxy Evolution Explorer has found a new recipe. view more (2009-02-19)
Universe contains more calcium than expected
The universe contains one and a half times more calcium than previously assumed. This conclusion was drawn by astronomers of the SRON Netherlands Institute for Space Research, after observations with ESA's XMM-Newton X-ray observatory. view more (2007-02-07)
New stars from old gas surprise astronomers
Evidence of star birth within a cloud of primordial gas has given astronomers a glimpse of a previously unknown mode of galaxy formation. The cloud, known as the Leo Ring, appears to lack the dark matter and heavy elements normally found in galaxies today. view more (2009-02-19)
German high-school students involved in an astronomical research project
This week, Astronomy & Astrophysics publishes a somewhat unusual research article because it is co-authored by German high-school students. view more (2009-11-06)
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)
Minor characters made medieval soap easier to follow
The complex stories about King Arthur and the Knights of the Round Table were well understood by medieval people. The predictable roles of various minor characters ensured that the listeners did not lose the thread of the story. This is the conclusion reached by Bernadette Smelik in her thesis: Minor characters in the Lancelot en prose. The... view more... (2002-05-23)
Astronomers weigh 'recycled' millisecond pulsar
A team of U.S. and Australian astronomers is announcing today that they have, for the first time, precisely measured the mass of a millisecond pulsar - a tiny, dead star spinning hundreds of times every second. view more (2006-01-13)
A Planet in Progress?
Scientists are one step closer to understanding how new planets form, thanks to research funded by the National Science Foundation (NSF) and carried out by a team of astrophysicists at the American Museum of Natural History. view more (2008-03-27)
Dwarf galaxies need dark matter too, U-M astronomers say
Stars in dwarf spheroidal galaxies behave in a way that suggests the galaxies are utterly dominated by dark matter, University of Michigan astronomers have found. view more (2007-10-25)
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 Purple Rose of Virgo
ntil now NGC 5584 was just one galaxy among many others, located to the West of the Virgo Cluster. Known only as a number in galaxy surveys, its sheer beauty is now revealed in all its glory in a new VLT image. Since 1 March, this purple cosmic rose also holds the brightest stellar explosion of the year, known as SN 2007af. view more (2007-03-28)
Delay in spotting TB is more common in white people and women
Delays in diagnosing tuberculosis are more common in white people and women, finds a study in this week’s BMJ. view more (2003-04-23)
