Evidence of liquid water in comets reveals possible origin of life
Comets contained vast oceans of liquid water in their interiors during the first million years of their formation, a new study claims. view more (2009-07-31)
Guess when a comet will be spotted to win a SOLARMAX DVD
ESA`s solar satellite, SOHO, has become the best comet spotter the world has ever known. When SOHO`s latest solar images are posted on the Internet, astronomers and space enthusiasts alike are thrilled when they spot evidence of new comets that have never been seen before as they pass close to the Sun. Since SOHO`s launch in 1995, 435 new comets... view more... (2002-05-10)
Did comets flood Earth's oceans?
Did the Earth form with water locked into its rocks, which then gradually leaked out over millions of years? Or did the occasional impacting comet provide the Earth's oceans? The Ptolemy experiment on Rosetta may just find out"¦ The Earth needed a supply of water for its oceans, and the comets are large celestial icebergs - frozen... view more... (2004-06-16)
Comet probes reveal evidence of origin of life, scientists claim
Recent probes inside comets show it is overwhelmingly likely that life began in space, according to a new paper by Cardiff University scientists. view more (2007-08-15)
Are comets at the origin of life on earth ?
For over 60 years now, the University of Liege Astrophysics and Geophysics Institute (IAGL) has been concerned with the study of comets. Again today, four of its researchers have just made a major discovery for the understanding of these celestial objects : a lot of extra heavy nitrogen detected in two comets suggests the presence of great... view more...

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)
Naked eye comet shines on UK National Astronomy Meeting
Naked eye comets are generally few and far between, so UK astronomers have been surprised and delighted by the appearance of comet C/2002 C1 (Ikeya-Zhang) in the night sky. Scientists are particularly intrigued by the re-appearance of Ikeya-Zhang after a long exile in the depths of the outer Solar System. According to Mark Bailey (Armagh... view more... (2002-04-04)
SOHO discovers its 1500th comet
The ESA/NASA SOHO spacecraft has just discovered its 1500th comet, making it more successful than all other comet discoverers throughout history put together. Not bad for a spacecraft that was designed as a solar physics mission. view more (2008-06-30)
UK pupils scan the skies for hazardous asteroids
Tracking newly discovered asteroids and comets to identify their orbits is the work of a small number of observatories. Yet UK students, using the Faulkes Telescope North - a remotely operated research quality telescope dedicated for educational use - will now be swelling these ranks. The students have taken such accurate data of a number of... view more... (2004-10-06)
Astronomers discover missing link for origin of comets
An international team of scientists that includes University of British Columbia astronomer Brett Gladman has found an unusual object whose backward and tilted orbit around the Sun may clarify the origins of certain comets. view more (2008-09-05)
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)
Evidence for more dust than ice in comets
Observations of Comet 9P/Tempel 1 made by ESA's Rosetta spacecraft after the Deep Impact collision suggest that comets are 'icy dirtballs', rather than 'dirty snowballs' as previously believed. view more (2005-10-14)
SOHO`s private view of a sunbathing comet
You could see it easily with your unaided eye (but don`t try!) if only Comet Machholz 1 were not so very close to the Sun. This unusual comet, reputed to flare up a lot, is today sweltering only 18 million kilometres from the Sun. This is its closest approach on an orbit that brings it back to the solar vicinity every 63 months. The best and... view more... (2002-01-09)
NASA's 'Deep Impact' Team Reports First Evidence of Cometary Ice
Comet Tempel 1, which created a flamboyant Fourth of July fireworks display in space last year, is covered with a small amount of water ice. view more (2006-02-03)
Chance encounter with comet nets surprising results
Comets are made of the most primitive stuff in the solar system. As hunks of rock and ice that never coalesced into more planets, they give researchers clues to the evolution of solar systems. view more (2007-10-02)
Mysterious carbon excess found in infant solar system
Astronomers detected unusually high quantities of carbon, the basis of all terrestrial life, in an infant solar system around nearby star Beta Pictoris, 63 light-years away. view more (2006-06-08)
NASA's Swift Looks to Comets for a Cool View
NASA's Swift Gamma-ray Explorer satellite rocketed into space in 2004 on a mission to study some of the highest-energy events in the universe. view more (2008-12-04)
UK Astronomers Watch the Skies for Threat from Space
British astronomers are providing a vital component to the world-wide effort of identifying and monitoring rogue asteroids and comets. From this month, the UK Astrometry and Photometry Programme (UKAPP) for Near-Earth Objects, based at Queens University, Belfast, will track Near-Earth Objects (NEOs) and feed their crucial information into the... view more...

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)
Primitive Visitor From Space Arrives In UK
Scientists from the Natural History Museum (NHM) in London, working with colleagues from the Open University (OU) in Milton Keynes, have been examining an intriguing arrival from outer space. The Tagish Lake meteorite, which fell in the Yukon region of northern Canada on the morning of 18 January 2000, contains some of the most primitive material... view more... (2001-03-31)
