Scientists Recreate Martian Environment
Scientists at the University of Leicester's Space Research Centre are recreating the hostile environment found on Mars in their laboratory, with a device known as the Martian Environment Simulator (MES). The machine reproduces the temperature, air pressure and unbreathable atmosphere known to exist on Mars. The MES is currently being used to test... view more... (2002-05-31)
Melting ice under pressure
The deep interior of Neptune, Uranus and Earth may contain some solid ice. Through first-principle molecular dynamics simulations, Lawrence Livermore National Laboratory scientists, together with University of California, Davis collaborators, used a two-phase approach to determine the melting temperature of ice VII (a high-pressure phase of ice)... view more...

First Mars, then Venus!
Fifteen days after the launch of Mars Express, Europe has reaffirmed its trust in Soyuz: next stop Venus in 2005! Just two weeks after the flawless launch of Mars Express on its way towards the Red Planet, ESA and the European-Russian company Starsem reinforced their relationship with the signature of the Venus Express launch services agreement.... view more...

New cleaning protocol for future 'search for life' missions
Scientists have developed a new cleaning protocol for space hardware, such as the scoops of Mars rovers, which could be used on future "Search for Life" missions on other planets. view more (2009-06-08)
Liquid water found flowing on Mars? Not yet
Liquid water has not been found on the Martian surface within the last decade after all, according to new research. view more (2008-02-29)
NASA'S Webb Telescope Sunshield Preliminary Design Review Complete
The tennis court-sized sunshield built by Northrop Grumman for NASA's James Webb Space Telescope has completed its preliminary design review at the company's Space Technology facility. view more (2008-03-24)
Computer simulation predicts Voyager 2 will reach major milestone in space in late 2007-early 2008
Using a computer model simulation, Haruichi Washimi, a physicist at UC Riverside, has predicted when the interplanetary spacecraft Voyager 2 will cross the "termination shock," the spherical shell around the solar system that marks where the solar wind slows down to subsonic speed. view more (2007-11-28)
Titan's pebbles 'seen' by Huygens radio
An unexpected radio reflection from the surface of Titan has allowed ESA scientists to deduce the average size of stones and pebbles close to the Huygens' landing site. The technique could be used on other lander missions to analyse planetary surfaces for free. view more (2006-07-26)
Tonga quake not conducive to tsunami
Seismologists at Washington University in St. Louis and their colleagues in Australia, Japan and Tonga have determined why a large earthquake in Tonga did not cause a large tsunami. view more (2007-03-13)
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)
Brown Scientist Answers How Peruvian Meteorite Made It to Earth
Brown University professor Peter Schultz's study of the Peruvian meteorite has yielded some interesting conclusions that could upend the conventional wisdom about the size and type of meteorites that can strike Earth. view more (2008-03-12)
New Planet Is Larger than Pluto
Claims that the Solar System has a tenth planet are bolstered by the finding by a group lead by Bonn astrophysicists that this alleged planet, announced last summer and tentatively named 2003 UB313, is bigger than Pluto. view more (2006-02-02)
Nullarbor fireball cameras find rare meteorite
Using cameras which capture fireballs streaking across the night sky and sophisticated mathematics, a world-wide team of scientists have managed to find not only a tiny meteorite on the vast Nullarbor Plain, but also its orbit and the asteroid it came from. view more (2009-09-18)
University of Western Ontario cameras capture 'fireball'
For the second time this year, The University of Western Ontario Meteor Group has captured incredibly rare video footage of a meteor falling to Earth. The team of astronomers suspects the fireball dropped meteorites in a region north of Guelph, Ontario, Canada, that may total as much as a few hundred grams in mass. view more (2008-10-27)
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)
Creating the astro-comb to locate Earth-like planets
Thanks to the ability of astronomers to detect the presence of extrasolar planets orbiting distant stars, scientists today are able to examine hundreds of solar systems. view more (2009-05-08)
A Window towards the Distant Universe
The Osservatorio Astronomico Capodimonte Deep Field (OACDF) is a multi-colour imaging survey project that is opening a new window towards the distant universe. It is conducted with the ESO Wide Field Imager (WFI), a 67-million pixel advanced camera attached to the MPG/ESO 2.2-m telescope at the La Silla Observatory (Chile). As a pilot project at... view more... (2001-04-11)
Understanding the global carbon budget -- Woods Hole Research Center expert provides insights
As climate change becomes more and more a central issue in local, national, and international discussions, understanding the global carbon budget, and how it influences trends in global warming, will become increasingly crucial. view more (2007-05-10)
Rosetta bound for outer Solar System after final Earth swingby
This morning, mission controllers confirmed that ESA's comet chaser Rosetta had swung by Earth at 8:45 CET as planned, skimming past our planet to pick up a gravitational boost for an epic journey to rendezvous with comet 67P/Churyumov-Gerasimenko in 2014. view more (2009-11-16)
New isotope molecule may add to Venus' greenhouse effect
Planetary scientists on both sides of the Atlantic have tracked down a rare molecule in the atmospheres of both Mars and Venus. The molecule, an exotic form of carbon dioxide, could affect the way the greenhouse mechanism works on Venus. view more (2007-10-11)
