Moons of Jupiter and Saturn could have been seeded with life
Life on Earth or Mars could have been brought to the moons of Jupiter or Saturn on rocks blasted off those planets, researchers say.
In HG Wells' 'The War of the Worlds', the invading Martians were beaten by that most unassuming of combatants – the common cold. Could the reverse happen and alien viruses pose a threat to human astronauts ...
How habitable is Mars? A new view of the Viking experiments
Almost 40 years ago, two NASA probes on the surface of Mars scooped the soil in search of signs of microbes. The results that came back from the twin Viking missions were, to say the least, ambiguous. The ...
Cosmic rays zap a planet's chances for life
Mysterious cosmic rays constantly bombard Earth from outer space. Now scientists find these energetic particles could limit where life as we know it might exist on alien planets.
Pilbara home to 3.5 billion-year-old bacterial ecosystems
(Phys.org) —Evidence of complex microbial ecosystems dating back almost 3.5 billion years has been found in Western Australia's Pilbara region by an international team including UWA Research Assistant Professor ...
Researchers reveal Earth's habitable lifetime and investigate potential for alien life
Habitable conditions on Earth will be possible for at least another 1.75 billion years – according to astrobiologists at the University of East Anglia.
Magnetic shielding of exomoons: to be or not to be
A new study on magnetic fields around extrasolar giant planets sheds first light on the magnetic environment of extrasolar moons. The work, authored by René Heller of the Department of Physics and Astronomy ...
If we landed on Europa, what would we want to know?
(Phys.org) —Most of what scientists know of Jupiter's moon Europa they have gleaned from a dozen or so close flybys from NASA's Voyager 2 spacecraft in 1979 and NASA's Galileo spacecraft in the mid-to-late ...
A warmer planetary haven around cool stars, as ice warms rather than cools
(Phys.org) —In a bit of cosmic irony, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. This is due to the interaction of a star's light with ice and snow on the planet's ...
Study shows how early Earth kept warm enough to support life
Solving the "faint young sun paradox"—explaining how early Earth was warm and habitable for life beginning more than 3 billion years ago even though the sun was 20 percent dimmer than today—may not be ...
Detecting DNA in space
If there is life on Mars, it's not too farfetched to believe that such Martian species may share genetic roots with life on Earth.
Mars Icebreaker Life mission
Missions to Mars have only scratched its surface. To go deeper, scientists are proposing a spacecraft that can drill into the Red Planet to potentially find signs of life.
Alien worlds resembling giant eyeballs might exist around red dwarf stars, and researchers are now proposing experiments to simulate these distant planets and see how capable they are of supporting life.
Astrobiology research: Life possible on extrasolar moons
(Phys.org)—In their search for habitable worlds, astronomers have started to consider exomoons, or those likely orbiting planets outside the solar system. In a new study, a pair of researchers has found ...
Some Earth bacteria survive and grow at extremely low pressure, may aid Mars research
(Phys.org)—University of Florida researchers have discovered for the first time that some Earth bacteria can live under the same low pressure conditions found on Mars.
