Astrobiology Magazine is a NASA-sponsored online popular science magazine. Established in the year 2000, Astrobiology Magazine now has a vast archive of stories covering a broad array of topics. Astrobiology Magazine covers science and nature topics relevant to space, innovation and biology, with an emphasis on the existence, detection and exploration of life in the universe.
Could 'green rust' be a catalyst for Martian life?
Mars is a large enough planet that astrobiologists looking for life need to narrow the parameters of the search to those environments most conducive to habitability.
Driest place on Earth hosts life
Researchers have pinpointed the driest location on Earth in the Atacama Desert, a region in Chile already recognised as the most arid in the world. They have also found evidence of life at the site, a discovery ...
Mystery methane on Mars: The saga continues
Is the Red Planet giving off methane? The question has taunted scientists for nearly 50 years, ever since the Mariner 7 spacecraft detected a whiff of the gas near Mars' south pole. Researchers retracted ...
Ether compounds could work like DNA on oily worlds
In the search for life beyond Earth, scientists have justifiably focused on water because all biology as we know it requires this fluid. A wild card, however, is whether alternative liquids can also suffice ...
Ancient star raises prospects of intelligent life
Can life survive for billions of years longer than the expected timeline on Earth? As scientists discover older and older solar systems, it's likely that before long we'll find an ancient planet in a habitable ...
Titan's atmosphere useful in study of hazy exoplanets
With more than a thousand confirmed planets outside of our solar system, astronomers are attempting to identify the atmospheres of these distant bodies to determine if they could possibly host life.
Iron-rich rocks could could hold signs of life
A robotic mission's search for life on Mars may seem worlds away from human scientists wandering around hot springs in Yellowstone National Park. But a study of the Yellowstone hot springs has revealed new ...
'Venus zone' narrows search for habitable planets
Long before the hunt began to find Earth lookalikes around other stars, one planet in the Solar System had already been named Earth's twin. With its similar size and mass, Venus measures very close to Earth, with one major yet signif ...
Viruses help microbial hosts cope with life at the extremes
A new study reveals that viruses lend a surprisingly helpful hand to microbes eking out a living near deep-sea hydrothermal vents.
Life needs an atmosphere, but how much is too much?
How much atmosphere is too much for life? As scientists discover more super-Earths and mini-Neptunes, the question becomes more relevant.
Europa's elusive water plume paints grim picture for life
A meteorite may have been responsible for a water plume briefly spotted above Europa two years ago, implying it takes a very rare event to breach the ice on the Jovian moon.
Public asked to help name features on Pluto
On July 14, NASA's New Horizons spacecraft will fly past Pluto, offering the first close-up look at that small, distant world and its largest moon, Charon. These denizens of the outer solar system will be ...
Could water have carved channels on Mars half a million years ago?
Could water have carved channels on Mars as recently as 500,000 years ago? If that's the case, it would boost the case for relatively recent life on the red planet.
Double impact crater in Canada formed in two separate impacts
An asteroid smashing into a planet can dramatically alter the planet's habitability by setting back evolution or even encouraging biodiversity.
Testing to diagnose power event in Mars rover
NASA's Curiosity Mars rover is expected to remain stationary for several days of engineering analysis following an onboard fault-protection action on Feb. 27 that halted a process of transferring sample material ...
