Extreme Winds Rule Exoplanet's Weather
Supersonic winds more than six times faster than those on Jupiter are blasting through the atmosphere of a Jupiter-sized planet 60 light years away, say scientists who've analyzed results from NASA's Spitzer Space Telescope.   view more (2007-05-10)

Largest, brightest supernova ever seen may be long-sought pair-instability supernova
An exploding star first observed last September is the largest and most luminous supernova ever seen, according to University of California, Berkeley, astronomers, and may be the first example of a type of massive exploding star rare today but probably common in the very early universe.   view more (2007-05-08)

Ten Inventions Created for James Webb Space Telescope Approved
Scientists and engineers have been working for years to develop ten technologies for NASA's James Webb Space Telescope, like big mirrors that will actually move around in space and computer software that will make it happen, or the materials that make up a giant sunshield as big as a tennis court.   view more (2007-05-04)

Astronomers find first habitable Earth-like planet
Astronomers have discovered the most Earth-like planet outside our Solar System to date, an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water.   view more (2007-04-25)

Kenya moves toward national food and nutrition policy
A team from the Friedman School of Nutrition Science and Policy at Tufts University is providing technical assistance to the East and Southern Africa Regional Office of the United Nations Children's Fund (EASRO UNICEF), the Food and Agriculture Organization of the United Nations (FAO), and the... view more (2007-04-24)

Global Earth Day broadcast to feature South Pole
Air quality research and ozone monitoring at the National Science Foundation's Amundsen-Scott South Pole will be showcased as part of a global Earth Day telecast scheduled for April 20, 2007, on various ABC-television's news programs.   view more (2007-04-20)

Iowa State astrophysicists provide the eyes for new gamma ray telescope system
There's a "First Light Fiesta" in the works at Mt. Hopkins near Amado, Ariz. And Iowa State University astrophysicists will be among those enjoying the celebration of a new telescope system and all the science it will produce.   view more (2007-04-20)

Mystery spiral arms explained?
Using a trio of space observatories, astronomers may have cracked a 45-year old mystery surrounding two ghostly spiral arms in the galaxy M106 (NGC 4258).   view more (2007-04-11)

Supernova Imposter Goes Supernova
In a galaxy far, far away, a massive star suffered a nasty double whammy. On Oct. 20, 2004, Japanese amateur astronomer Koichi Itagaki saw the star let loose an outburst so bright that it was initially mistaken for a supernova. The star survived, but for only two years. On Oct. 11, 2006,... view more (2007-04-05)

Prototype for long wavelength array sees first light
Astronomers at the Naval Research Laboratory (NRL) have produced the first images of the sky from a prototype of the Long Wavelength Array (LWA), a revolutionary new radio telescope to be constructed in southwestern New Mexico.   view more (2007-03-30)

Amateurs and professionals combine observations to produce detailed picture of double asteroid
Roping together observations from the world's largest telescopes as well as the small instrument of a local backyard amateur, astronomers have assembled the most complete picture yet of a pair of asteroids whirling around one another in a perpetual pas de deux.   view more (2007-03-30)

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... view more (2007-03-28)

Robotic telescope unravels mystery of cosmic blasts
Scientists have used the world's largest robotic telescope to make the earliest-ever measurement of the optical polarisation* of a Gamma Ray Burst (GRB) just 203 seconds after the start of the cosmic explosion. This finding, which provides new insight into GRB physics, is published in Science today... view more (2007-03-19)

Star Family Seen Through Dusty Fog
Images made with ESO's New Technology Telescope at La Silla by a team of German astronomers reveal a rich circular cluster of stars in the inner parts of our Galaxy. Located 30,000 light-years away, this previously unknown closely-packed group of about 100,000 stars is most likely a new globular... view more (2007-03-14)

New panorama reveals more than a thousand black holes
By casting a wide net, astronomers have captured an image of more than a thousand supermassive black holes. These results give astronomers a snapshot of a crucial period when these monster black holes are growing, and provide insight into the environments in which they occur.   view more (2007-03-13)

Light Gives Asteroids Spin
Astronomers have observed an asteroid change the rate at which it spins for the first time, and shown that this is due to a theoretical effect predicted but never before seen   view more (2007-03-12)

AEGIS survey reveals new principle governing galaxy formation and evolution
Faced with the bewildering array of galaxies in the universe, from orderly spirals to chaotic mergers, it is hard to imagine a unifying principle that describes them all with mathematical precision. But that is just what astronomers have now discovered.   view more (2007-03-07)

Hubble sees 'Comet Galaxy' being ripped apart by galaxy cluster
There are many galaxies of different shapes and sizes around us today. Roughly half are gas-poor elliptical-shaped galaxies with little new star formation activity, and half are gas-rich spiral and irregular galaxies with high star formation activity. Observations have shown that gas-poor galaxies... view more (2007-03-05)

Chandra examines Jupiter during new horizons approach
On February 28, 2007, NASA's New Horizons spacecraft made its closest approach to Jupiter on its ultimate journey to Pluto. This flyby gave scientists a unique opportunity to study Jupiter using the package of instruments available on New Horizons, while coordinating observations from both space-... view more (2007-03-02)

Pluto-Bound New Horizons Spacecraft Gets a Boost from Jupiter
NASA's New Horizons spacecraft successfully completed a flyby of Jupiter early this morning, using the massive planet's gravity to pick up speed on its 3-billion mile voyage to Pluto and the unexplored Kuiper Belt region beyond.   view more (2007-03-01)

XMM-Newton's anniversary view of supernova SN 1987A
Twenty years after the first detection of SN 1987A, the nearest supernova ever detected since the invention of the telescope, XMM-Newton provided a fresh-new view of this object. The source keeps brightening-XMM-Newton confirms.   view more (2007-02-26)
