Floating pile of rubble a pristine record of solar system's history
A small, near-Earth asteroid named Itokawa is just a pile of floating rubble, probably created from the breakup of an ancient planet, according to a University of Michigan researcher was part of the Japanese space mission Hayabusa. view more (2006-06-02)
Look out for giant triangles in space
THE search for extraterrestrial intelligence (SETI) could be taking the wrong approach. Instead of listening for alien radiobroadcasts, a better strategy maybe to look for giant structures placed in orbit around nearby stars by alien civilisations. view more (2005-04-06)
A Vanishing Star Revisited
Reinhold H'¤fner of the Munich University Observatory (Germany) is a happy astronomer. view more (1999-07-20)
Astronomy's bright future
To mark UNESCO's International Year of Astronomy (IYA2009), six leading astronomers from the UK, the US, Europe and Asia write in March's Physics World about the biggest challenges and opportunities facing international astronomers over the next couple of decades. view more (2009-03-02)
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)
Planet or failed star? One of smallest stellar companions seen by Hubble
Astronomers using the NASA/ESA Hubble Space Telescope have photographed one of the smallest objects ever seen around a normal star beyond our Sun. Weighing in at 12 times the mass of Jupiter, the object is small enough to be a planet. view more (2006-09-11)
Mars Express mission extended
ESA's Mars Express mission has been extended by one Martian year, or about 23 months, from the beginning of December 2005. view more (2005-09-23)
New capture scenario explains origin of Neptune's oddball moon Triton
Neptune's large moon Triton may have abandoned an earlier partner to arrive in its unusual orbit around Neptune. view more (2006-05-11)
Venus Express' infrared camera goes filming
An exciting new series of videos from ESA's Venus Express has been capturing atmospheric details of day and night areas simultaneously, at different altitudes. view more (2007-05-08)
Trees to offset the carbon footprint?
How effective are new trees in offsetting the carbon footprint? A new study suggests that the location of the new trees is an important factor when considering such carbon offset projects. Planting and preserving forests in the tropics is more likely to slow down global warming. view more (2007-04-10)
Volcanic Activity Shaped Mercury After All
Scientists have long anguished over how little is known about Mercury, the innermost of the four terrestrial planetary bodies in our solar system. view more (2008-07-07)
Planets like earth may have formed around other stars, UCLA astronomers report
The chemical fingerprint of a burned-out star indicates that Earth-like planets may not be rare in the universe and could give clues to what our solar system will look like when our sun dies and becomes a white dwarf star some five billion years from now. view more (2007-08-20)
Astonomers find tiny planet orbiting tiny star
An international team of astronomers led by David Bennett of the University of Notre Dame has discovered an extra-solar planet of about three Earth masses orbiting a star with a mass so low that its core may not be large enough to maintain nuclear reactions. The result was presented Monday (June 2) at the American Astronomical Society annual... view more... (2008-06-03)
Physicists create millimeter-sized 'Bohr atom'
Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, a Rice University-led team of physicists has created giant, millimeter-sized atoms that resemble it more closely than any other experimental realization yet achieved. view more (2008-07-01)
Life And Death In Space
Ever since its formation at the birth of the Solar System, some 4570 million years ago, planet Earth has resembled a giant bulls-eye in space, a target for asteroids and comets of all shapes and sizes. Clearly, this violent history has influenced the planet's surface and atmosphere, as well as the evolution of life. Some impactors bring water and... view more... (2003-04-05)
APL Astronomer Spies Conditions 'Just Right' for Building an Earth
An Earth-like planet is likely forming 424 light-years away in a star system called HD 113766, say astronomers using NASA's Spitzer Space Telescope. view more (2007-10-04)
Wales hosts world workshop for better conservation
These special scientists, known as taxonomists are members of BioNET International, the brainchild of Professor Tecwyn Jones of Cardiff University. They are skilled in the science concerned with identifying, classifying and understanding the relationships of the myriad species of organisms which form the Earth's biodiversity. view more (1999-08-16)
Magnetic Tornadoes Could Liberate Mercury's Tenuous Atmosphere
As the closest planet to the sun, Mercury is scorching hot, with daytime temperatures of more than 800 degrees Fahrenheit (approximately 450 degrees Celsius). view more (2009-06-03)
Geoscience converges under pressure
The contents of the deep Earth affect the planet as a whole, including life at its surface, but scientists must find unusual ways to "see" it. view more (2007-05-22)
Where did Venus's water go?
Venus Express has made the first detection of an atmospheric loss process on Venus's day-side. Last year, the spacecraft revealed that most of the lost atmosphere escapes from the night-side. view more (2008-12-19)
