Primitive asteroids in the main asteroid belt may have formed far from the sun
Many of the objects found today in the asteroid belt located between the orbits of Mars and Jupiter may have formed in the outermost reaches of the solar system. view more (2009-07-16)
Fog lifted on 'dark' gamma-ray bursts, mysterious counterparts to bursts with an afterglow
Gamma-ray bursts, with their ability to pierce through gas and dust to shine brightly across the universe, are revealing areas of intense star formation and stellar death where astronomers have been unable to look - the dusty corners of otherwise dust-free galaxies. view more (2009-06-09)
Hubble panoramic view of Orion Nebula reveals thousands of stars
In one of the most detailed astronomical images ever produced, the NASA/ESA Hubble Space Telescope is offering an unprecedented look at the Orion Nebula. view more (2006-01-12)
Earliest Stage of Planet Formation Dated
UC Davis researchers have dated the earliest step in the formation of the solar system -- when microscopic interstellar dust coalesced into mountain-sized chunks of rock -- to 4,568 million years ago, within a range of about 2,080,000 years. view more (2007-12-20)
Planets forming in Pleiades star cluster, astronomers report
Rocky terrestrial planets, perhaps like Earth, Mars or Venus, appear to be forming or to have recently formed around a star in the Pleiades ("seven sisters") star cluster, the result of "monster collisions" of planets or planetary embryos. view more (2007-11-16)
NASA Africa mission investigates origin, development of hurricanes
Scientists from NASA, the National Oceanic and Atmospheric Administration, universities and international agencies will study how winds and dust conditions from Africa influence the birth of hurricanes in the Atlantic Ocean. view more (2006-07-27)
Rosetta warms up for Mars swing-by
This month the team working on ESA's Rosetta mission have been particularly busy. Activities are underway to set the spacecraft's trajectory and prepare the on-board instruments ready for the next major mission milestone: the swing-by of planet Mars in February 2007. view more (2006-11-30)
Infrared Echoes Give NASA's Spitzer a Supernova Flashback
Hot spots near the shattered remains of an exploded star are echoing the blast's first moments, say scientists using data from NASA's Spitzer Space Telescope. view more (2008-10-02)
Study: Soybean oil reduces carbon footprint in swine barns
One of agriculture's most versatile crops could one day play a role in combating climate change, Purdue University research shows. view more (2009-02-27)
NASA/University team develops new method to find alien oceans
NASA-sponsored scientists looking back at Earth with the Deep Impact/EPOXI mission have developed a method to indicate whether Earth-like alien (extrasolar) worlds have oceans. view more (2009-05-27)
Mapping Orion's winds
For the past few months, Bob O'Dell has been mapping the winds blowing in the Orion Nebula, the closest stellar nursery similar to the one in which the sun was born. view more (2006-01-11)
More than half the US population is sensitive to one or more allergens
More than fifty percent of the U.S. population tested positive to one or more allergens, according to a large national study. view more (2005-08-05)
Researchers: Molecular forklifts overcome obstacle to 'smart dust'
Algae is a livid green giveaway of nutrient pollution in a lake. Scientists would love to reproduce that action in tiny particles that would turn different colors if exposed to biological weapons, food spoilage or signs of poor health in the blood. view more (2009-01-20)
Cassini findings suggest complex story of venting at the south pole of Enceladus
Evidence is mounting that the atmosphere of Enceladus, first detected by the Cassini Magnetometer instrument, is the result of venting from ground fractures close to the moon's south pole. view more (2005-08-31)
Rapid-born planets present 'baby picture' of our early solar system
Using NASA's Spitzer Space Telescope, a team of astronomers led by the University of Rochester has detected gaps ringing the dusty disks around two very young stars, which suggests that gas-giant planets have formed there. view more (2005-09-12)
Galaxies of stars shrouded in dust found in the early universe
A team of astronomers based in the UK and the US has for the first time measured the redshifts of a significant sample of puzzling "submillimetre galaxies", discovered by some members of the team in 1997. Dr Ian Smail of the University of Durham will tell the UK/Ireland National Astronomy Meeting that these are remote galaxies with high redshifts,... view more... (2003-03-31)
ESA Science Media Day: Rosetta and Integral getting ready for launch
ESA PR 42-2002. Two contrasting space missions are in the final stages of preparation at ESA`s Space Research and Technology Centre (ESTEC) in Noordwijk, the Netherlands. They are the Rosetta mission to rendezvous with Comet Wirtanen and study the origins of our solar system and the Integral spacecraft to study the most violent phenomena in the... view more...

Cassini Helps Redraw Shape of Solar System
In a paper published Oct. 15 in Science, researchers from the Johns Hopkins Applied Physics Laboratory (APL) present a new view of the region of the sun's influence, or heliosphere, and the forces that shape it. Images from one of the Magnetospheric Imaging Instrument's sensors, the Ion and Neutral Camera (MIMI/INCA), on NASA's Cassini spacecraft... view more... (2009-10-16)
Water table depth tied to droughts
Will there be another "dust bowl" in the Great Plains similar to the one that swept the region in the 1930s? view more (2008-09-30)
We Owe It All to Comets
Comets have always fascinated us. A mysterious appearance could symbolize God's displeasure or mean a sure failure in battle, at least for one side. view more (2009-04-29)
