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)
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)
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)
ESA scientist discovers a way to shortlist stars that might have planets
Markus Landgraf of the European Space Agency and colleagues (*) have found the first direct evidence that a bright disc of dust surrounds our Solar System, starting beyond the orbit of Saturn. Remarkably, their discovery gives astronomers a way to determine which other stars in the Galaxy are most likely to harbour planets and allows mission... view more... (2002-02-15)
Even 'failed stars' form planets
An international team of astronomers shows that even brown dwarfs start to form planets. view more (2005-10-26)
Unexpected cooling effect in Saturn's upper atmosphere
UK researchers from University College London (UCL), along with colleagues from Boston University, have found that the hotter than expected temperature of Saturn's upper atmosphere - and that of the other giant planets - is not due to the same mechanism that heats the atmosphere around the Earth's Northern Lights. view more (2007-01-29)
100th Extra-solar planet gives clues to origins of planets
British astronomers, together with Australian and American colleagues, have used the 3.9m Anglo-Australian Telescope [AAT] in New South Wales, Australia to discover a new planet outside our Solar System - the 100th to be detected. The discovery, which is part of a search for solar systems that resemble our own, will be announced today (Tuesday) at... view more... (2002-09-16)
Space Man Joins BBC Voyage Around The Solar System
A Kingston University space expert has been reaching out to the stars after lending his specialist knowledge to a major TV drama-documentary. Director of the University's Aerospace Research Centre Dr Chris Welch has been working with the makers of BBC One series, Space Odyssey: Voyage to the Planets, which hits our screens next month. The... view more... (2004-10-20)
MIT finds young planets stay hotter longer
Hot, young planets may be easier to spot because they stay that way longer than astronomers have thought, according to new work by MIT planetary scientist Linda Elkins-Tanton. view more (2008-10-16)
Finding Twin Earths: Harder Than We Thought!
Does a twin Earth exist somewhere in our galaxy? Astronomers are getting closer and closer to finding an Earth-sized planet in an Earth-like orbit. NASA's Kepler spacecraft just launched to find such worlds. view more (2009-03-23)
Wobbly planets could reveal Earth-like moons
Moons outside our Solar System with the potential to support life have just become much easier to detect, thanks to research by an astronomer at University College London (UCL). view more (2008-12-12)
Press invitation: Big bucks for Big Bang scientists
A £1.7 million science laboratory for studying one of the great mysteries of the Universe opens at the University of Sussex on May 14, 2002. The Centre for the Measurement of Particle Electric Dipole Moments has been equipped with the very latest technology to help scientists discover what happened in the aftermath of the 'Big Bang'. Ed... view more... (2002-05-07)
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)
Astronomers use ultra-sensitive camera to measure size of planet orbiting star
A team of astronomers led by John Johnson of the University of Hawaii's Institute for Astronomy has used a new technique to measure the precise size of a planet around a distant star. They used a camera so sensitive that it could detect the passage of a moth in front of a lit window from a distance of 1,000 miles. view more (2008-12-11)
Astronomers find stellar cradle where planets form
Astronomers at the University of Illinois have found the first clear evidence for a cradle in space where planets and moons form. view more (2007-11-30)
Gas giants jump into planet formation early
Observations from NASA's Spitzer Space Telescope show that gas giants either form within the first 10 million years of a sun-like star's life, or not at all. view more (2007-01-09)
Dirty stars make good solar system hosts
Some stars are lonely behemoths, with no surrounding planets or asteroids, while others sport a skirt of attendant planetary bodies. New research published this week in The Astrophysical Journal Letters explains why the composition of the stars often indicates whether their light shines into deep space, or whether a small fraction shines onto... view more...

Massive Transiting Planet with 31-hour Year Found Around Distant Star
An international team of astronomers with the Trans-atlantic Exoplanet Survey today announce the discovery of their third planet, TrES-3. view more (2007-06-01)
Cranfield University reaches for the stars
Looking into the night sky you may see a few stars and the moon. Astronomers, however, are looking for more than this - they are looking for Earth-like planets, which, with a little help from Cranfield University, they may be able to find. As part of a four-year collaborative project, Cranfield University professors Paul Shore, Dave Stephenson and... view more... (2004-02-13)
Earth-like planets may be more common than once thought, says new U. of Colorado-Penn State study
More than one-third of the giant planet systems recently detected outside Earth's solar system may harbor Earth-like planets, many covered in deep oceans with potential for life. view more (2006-09-08)
