A comprehensive review by leading scientists about our Solar System which speculates on the possibility of life on other planets has been published.   view more (2006-09-13)

Does life exist on other planets?
Recent research argues that an atmosphere rich in oxygen is the most likely source of energy for complex life to exist anywhere in the Universe, thereby limiting the number of places life may exist.   view more (2005-06-20)

Soggy Sands of Mars?
Cracks and fins in the sand in an American desert look very similar to features seen on Mars and may indicate the recent presence of water at the surface.   view more (2006-04-07)

Rare high-altitude clouds found on Mars
Planetary scientists have discovered the highest clouds above any planetary surface. They found them above Mars using the SPICAM instrument on board ESA's Mars Express spacecraft. The results are a new piece in the puzzle of how the Martian atmosphere works.   view more (2006-08-29)

The world's oldest bacteria
A research team has for the first time ever discovered DNA from living bacteria that are more than half a million years old. Never before has traces of still living organisms that old been found.   view more (2007-08-28)

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)

Water detection at Gusev crater described
A large team of NASA scientists, led by earth and planetary scientists at Washington University in St. Louis details the first solid set of evidence for water having existed on Mars at the Gusev crater, exploration site of the rover Spirit.   view more (2005-09-08)

New cocoa evidence on why plant foods are beneficial to cardiovascular health
While a growing number of studies has shown a link between flavanol-rich cocoa and cardiovascular health, scientists have now substantiated a causal relationship between specific compounds present in cocoa and cardiovascular health.   view more (2006-01-17)

Geologists finding a different Mars underneath
Scientists are finding an older, craggier face of Mars buried beneath the surface, thanks to pioneering sounding radar co-sponsored by NASA aboard the European Space Agency's Mars Express spacecraft.   view more (2006-12-14)

Finally, JAP study shows headdown bedrest precisely mimics human physiology in spaceflight
With President Bush talking up trips to the moon and Mars, and a new satellite circling the red planet, ever wonder what it feels like in space?   view more (2006-03-28)

NASA images, White Sands features support a wetter Mars
NASA's announcement yesterday of evidence that water still flows on Mars, at least in brief spurts, demonstrates that the view of Mars as a very dry planet should be reevaluated, says Dawn Sumner, professor of geology at UC Davis. Recent work from by Sumner and graduate student Greg Chavdarian also... view more (2006-12-08)

Titan's seas are sand
Until a couple of years ago, scientists thought the dark equatorial regions of Titan might be liquid oceans.   view more (2006-05-05)

ASU geologists suggest Mars features are result of meteorite strikes, not of evaporated lakes
Geologic features at the Opportunity landing site on Mars were formed not by a lake that evaporated but by constant strikes from meteorites, say two Arizona State University geologists.   view more (2005-12-22)

Path to Finding Life on Mars and in Outer Space
Clues to finding current or past life on Mars now or at some point in the past begins with an examination of Earth's most extreme environments and the adaptable microscopic life that thrives there.   view more (2006-02-02)

Hundreds of auroras detected on Mars
Auroras similar to Earth's Northern Lights appear to be common on Mars, according to physicists at the University of California, Berkeley, who have analyzed six years' worth of data from the Mars Global Surveyor.   view more (2005-12-13)

Follow the nitrogen to extraterrestrial life
The great search for extraterrestrial life has focused on water at the expense of a crucial element, say geobiologists at the University of Southern California.   view more (2006-05-05)

Scientists discover Mars' atmosphere altered by solar flares
Boston University astronomers announced today the first clear evidence that solar flares change the upper atmosphere of Mars.   view more (2006-02-24)

Mars under the spotlight again
Relieved UK scientists are celebrating the news that NASA's Mars Reconnaissance Orbiter (MRO) appears to have smoothly entered Mars orbit on Friday night (March 10th).   view more (2006-03-14)

Rocks could reveal secrets of life on Earth - and Mars
A new UK project could help detect evidence for life on Mars, as well as improve our understanding of how it evolved on Earth. The aim is to develop a technique that can identify biomolecules in water that have been trapped in rocks for millions to billions of years. As well as analysing samples... view more (2003-10-09)

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... view more (2007-01-29)

Flavanol-rich cocoa improves blood vessel function in aging baby boomer study participants
Flavanol-rich cocoa could offer powerful cardiovascular benefits for the nearly 78 million baby boomers in the United States today, suggests a new study published in the August issue of the Journal of Hypertension.   view more (2006-08-02)

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)

Ice clouds put Mars in the shade
Until now, Mars has generally been regarded as a desert world, where a visiting astronaut would be surprised to see clouds scudding across the orange sky. However, new results show that the arid planet possesses high-level clouds that are sufficiently dense to cast a shadow on the surface.   view more (2008-01-17)

Models show one nearby star system could host Earth-like planet
The steady discovery of giant planets orbiting stars other than our sun has heightened speculation that there could be Earth-type worlds in nearby planetary systems capable of sustaining life.   view more (2006-07-25)
