Reading the planetary tea leaves
An international team of astronomers is one step closer to answering the question, "Will the world end with a bang or a whimper?"   view more (2007-09-24)

Good news: How the Earth will survive when the Sun becomes a supergiant
The astronomy textbooks will have to be rewritten, say astrophysicists at the University of Sussex who have re-examined standard calculations about solar evolution and the distant future of the Earth. The textbooks tell us that one day the Sun will burn up its nuclear fuel and expand to an enormous... view more (2002-01-08)

Mars Express has the sophisticated science to find the water ice on Mars
"The presence of such a large amount of water ice under Mars`s surface is very surprising. Especially so close to the surface!" says Gerhard Schwehm, Head of the Planetary Missions Division at ESA. The team working on ESA`s Mars Express, the next mission to the Red Planet, is thrilled by NASA`s... view more (2002-05-30)

UCF professor finds that hottest measured extrasolar planet is 3700 degrees
"HD 149026b is simply the most exotic, bizarre planet," Harrington said. "It's pretty small, really dense, and now we find that it's extremely hot."   view more (2007-05-10)

Mineral discovery explains Mars' landscape
A Queen's University researcher has discovered a mineral that could explain the mountainous landscape of Mars, and have implications for NASA's next mission to the planet.   view more (2006-10-24)

A Trio of Super-Earths
Today, at an international conference, a team of European astronomers announced a remarkable breakthrough in the field of extra-solar planets. Using the HARPS instrument at the ESO La Silla Observatory, they have found a triple system of super-Earths around the star HD 40307.   view more (2008-06-17)

A Planet in Progress?
Scientists are one step closer to understanding how new planets form, thanks to research funded by the National Science Foundation (NSF) and carried out by a team of astrophysicists at the American Museum of Natural History.   view more (2008-03-27)

Marsquake detection sensors will take search for water underground
Researchers at Imperial College London have just begun a 5-year project to design and build tiny earthquake measuring devices to go to Mars on the 2007 NetLander mission. Unlike the instruments on next year`s European Mars Express/Beagle II mission, the Marsquake sensors will be the first to look... view more (2002-05-30)

Preparing for the Venus Express
The European Space Agency is planning its first mission to unveil the mysteries of Earth`s cloud-shrouded sister planet, Venus. On Wednesday 10 April, Professor Fred Taylor (University of Oxford) will be explaining to the UK National Astronomy Meeting why European scientists are hoping to be on... view more (2002-04-03)

Scientists Discover New Planet Orbiting Dangerously Close to Giant Star
A team of astronomers from Penn State and Nicolaus Copernicus University in Poland has discovered a new planet that is closely orbiting a red-giant star, HD 102272, which is much older than our own Sun.   view more (2008-11-19)

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... view more (2002-09-16)

Gifted Students Create Martian Movies and Design their Own Space Odyssey
Some of the brightest kids in the country who are members of the National Academy for Gifted and Talented Youth (NAGTY), based at the University of Warwick, will explore life on other planets and create an animation of what Mars probe Beagle 2 may have found if it had suceeded, or what NASA's... view more (2004-02-17)

A Warm South Pole? Yes, on Neptune!
An international team of astronomers using ESO's Very Large Telescope has discovered that the south pole of Neptune is much hotter than the rest of the planet. This is consistent with the fact that it is late southern summer and this region has been in sunlight for about 40 years.   view more (2007-09-19)

Understanding the oceans microbes is key to the Earth's future
Life on Earth may owe its existence to tiny microorganisms living in the oceans, but the effect of human-induced change on the vital services these microbes perform for the planet remains largely unstudied.   view more (2005-12-09)

The IAU draft definition of 'planet' and 'plutons'
The world's astronomers, under the auspices of the International Astronomical Union (IAU), have concluded two years of work defining the difference between "planets" and the smaller "solar system bodies" such as comets and asteroids.   view more (2006-08-16)

Chronicle of Martian Expedition
A man is the most vulnerable chain in long-term space expedition. How numerous should a crew be? What are the principles of a crew selection? What should be made to protect people during a flight and on some other planet? Scientists from the Institute for Problems of Medicine and Biology are trying... view more (2001-04-20)

Interstellar Weather Report: Day and Night Temps Measured on an Extrasolar Planet
For the first time, astronomers have measured the day and night temperatures of a planet outside our solar system. The team, which includes Sara Seager of Carnegie's Department of Terrestrial Magnetism, revealed that a giant Jupiter-like gas planet orbiting very close to its star is blisteringly... view more (2006-10-13)

Earth light: Terrestrial vegetation detected in the spectrum of the earthshine
A team including Pierre Riaud and Jean Schneider of the Observatoire de Paris and Luc Arnold, Sophie Gillet and Olivier Lardie're of the Observatoire de Haute Provence detected for the first time the color characteristic of the terrestrial vegetation in the "Earthshine", i.e. the dark part of the... view more (2002-01-23)

Hubble finds first organic molecule on extrasolar planet
The tell-tale signature of the molecule methane in the atmosphere of the Jupiter-sized extrasolar planet HD 189733b has been found with the Hubble Space Telescope. Under the right circumstances methane can play a key role in prebiotic chemistry - the chemical reactions considered necessary to form... view more (2008-03-20)

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)
