Aircraft and radar antenna help test instruments for space mission
The CLRC Chilbolton Observatory in Hampshire has been host to scientists from the UK, France, Germany and the Netherlands who have been testing radar and lidar instruments on board three separate aircraft, together with many ground-based instruments, to test the feasibility for a future European space mission which will gather data from space on... view more...

Stars Form Surprisingly Close to Milky Way's Black Hole
NASA's Chandra X-ray Observatory revealed a new generation of stars spawned by a super-massive black hole at the center of the Milky Way galaxy. view more (2005-10-14)
Galaxy collisions dominate the local universe
More than half of the largest galaxies in the nearby universe have collided and merged with another galaxy in the past two billion years, according to a Yale astronomer in a study using hundreds of images from two of the deepest sky surveys ever conducted. view more (2005-12-06)
Astronomers discover record 5th planet around nearby star 55 Cancri
A team of American astronomers announced today (Tuesday, Nov. 6) the discovery of a record-breaking fifth planet around the nearby star 55 Cancri, making it the only star aside from the sun known to have five planets. view more (2007-11-07)
XMM-Newton reveals X-rays from gas streams around young stars
XMM-Newton has surveyed nearly two hundred stars under formation to reveal, contrary to expectations, how streams of matter fall onto the young stars' magnetic atmospheres and radiate X-rays. view more (2007-06-01)
Rogue Black Holes May Roam the Milky Way
It sounds like the plot of a sci-fi movie: rogue black holes roaming our galaxy, threatening to swallow anything that gets too close. In fact, new calculations by Ryan O'Leary and Avi Loeb (Harvard-Smithsonian Center for Astrophysics) suggest that hundreds of massive black holes, left over from the galaxy-building days of the early universe, may... view more...

Spitzer nets thousands of galaxies in a giant cluster
In just a short amount of time, NASA's Spitzer Space Telescope has bagged more than a thousand previously unknown dwarf galaxies in a giant cluster of galaxies. view more (2007-05-29)
Late Afternoon at Taruntius
Amazingly Sharp VLT Image of Lunar Landscape Thirty-three years after the first manned landing on the Moon, the ESO Very Large Telescope (VLT) has obtained what may be the sharpest image of the lunar surface ever recorded from the ground. It was made with the NAOS-CONICA (NACO) adaptive optics camera mounted on the ESO VLT 8.2-m YEPUN telescope at... view more... (2002-08-09)
ESA's Rosetta mission: A status report
Following the decision not to launch Europe's comet chaser Rosetta in January, scientists and engineers in the programme have been examining several alternative mission scenarios. Each has been looked at on the basis of the expected scientific return, the technical risks related to using the Rosetta design in the new mission, and the containment... view more... (2003-03-21)
Ghost Remains After Black Hole Eruption
NASA's Chandra X-ray Observatory has found a cosmic "ghost" lurking around a distant supermassive black hole. This is the first detection of such a high-energy apparition, and scientists think it is evidence of a huge eruption produced by the black hole. view more (2009-05-29)
Adaptive optics leads the way to supermassive black holes
Astronomers have discovered the exact location and makeup of a pair of supermassive black holes at the center of a collision of two galaxies more than 300 million light years away. view more (2007-05-18)
Old idea spawns new way to study dark matter
An international team of astronomers led by Ohio State University has examined dark matter in the outer reaches of our galaxy in a new way. For the first time, they were able to employ triangulation -- a method rooted in ancient Greek geometry -- to estimate the location of dark matter and calculate its mass. view more (2007-05-31)
Solar wind tans young asteroids
A new study published in Nature this week reveals that asteroid surfaces age and redden much faster than previously thought -- in less than a million years, the blink of an eye for an asteroid. This study has finally confirmed that the solar wind is the most likely cause of very rapid space weathering in asteroids. This fundamental result will... view more... (2009-04-23)

It's far, it's small, it's cool: It's an icy exoplanet!
Using a network of telescopes scattered across the globe, including the Danish 1.54m telescope at ESO La Silla (Chile), astronomers discovered a new extrasolar planet significantly more Earth-like than any other planet found so far. view more (2006-01-26)
Iowa State researchers contribute to discovery of gamma rays from starburst galaxy
Iowa State University astrophysicists contributed to the recent discovery that a galaxy quickly creating new stars is also a source of high energy gamma rays. view more (2009-11-03)
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)
Chandra discovers light echo from the Milky Way's Black Hole
Like cold case investigators, astronomers have used NASA's Chandra X-ray Observatory to uncover evidence of a powerful outburst from the giant black hole at the Milky Way's center. view more (2007-01-11)
Astronomers find puzzling dwarf star with complex magnetic fields
Typically, little M-dwarf stars-the most common type of star in the galaxy-are cold, quiet, and dim. Now a team of astronomers led by Edo Berger, a Carnegie-Princeton postdoctoral fellow, found one M-dwarf that doesn't conform. view more (2007-12-06)
VERITAS telescopes help solve 100-year-old mystery: The origin of cosmic rays
Nearly 100 years ago, scientists detected the first signs of cosmic rays - subatomic particles (mostly protons) that zip through space at nearly the speed of light. view more (2009-11-03)
