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.
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.
The Rio Scale: Quantifying the consequences of an ET discovery
Among the mysteries of the Universe that are able to be investigated by science, the possibility of extraterrestrial intelligence remains one of the most fascinating.
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.
Under pressure: How the density of exoplanets' atmospheres weighs on the odds for alien life
At this early stage in the search for extraterrestrial life in our solar system and beyond, the emphasis is on liquid water. Where it can exist on a planet's or moon's surface, so the thinking goes, life ...
The 'habitable edge' of exomoons
Astronomers have their fingers crossed that within the haul of data collected by NASA's Kepler mission, which has already detected nearly three thousand possible exoplanets, hide the signatures of the very ...
Searching for organics in a nibble of soil
You might call it a high-tech panhandler, with its design for sifting through sprinkles of dirt to find tiny specks of organic material. Or you might think of it as a soil-eating-micro-espresso machine that ...
Storms in the machine
NASA researchers are constructing a statistical typhoon model that can quickly generate millions of synthetic typhoons from birth through termination. Their work could provide new details about the climate ...
At last, how many alien civilizations are there?
During the space age, 1961 was a special year: the Russian cosmonaut Yuri Gagarin became the first man to orbit Earth, while the American astronomer Frank Drake developed the now famous Drake Equation. This ...
Could chlorofluorocarbons someday provide evidence of alien life?
Hairspray might one day serve as the sign that aliens have reshaped distant worlds, researchers say. Such research to find signs of alien technology is now open to funding from the public. ...
A 3.45-billion-year-old diet
Researchers are providing new information about the 'diet' of microorganisms on the early Earth. By studying 3.45-billion-year-old rocks, the team uncovered clues about ancient microbial metabolism.
The magnetic wakes of pulsar planets
Pulsars are among the most extreme stars in the universe: dense balls of matter which are heavier than the Sun, yet only a few tens of kilometers in diameter. They rotate rapidly (up to several hundred revolutions ...
Gases created when meteors slam into planets may provide false-positives of life
Meteoroids slamming against the atmospheres of alien worlds could add organic gases that make them look inhabited by life even if they are not, researchers say.
Triton: A subsurface ocean?
Neptune's largest moon Triton is most likely a captured Kuiper Belt Object. The capture of icy Triton and the subsequent taming of its orbit likely led to the formation of a subsurface ocean through tidal ...
The Kuiper Belt at 20
Planetary science is celebrating the 20th anniversary of the discovery of the Kuiper Belt. That came in 1992, when the first Kuiper Belt Object (KBO) was discovered.
How old are the first planets?
To build a planet you need lots of rubble and that means lots of heavy elements – stuff more massive than atoms of hydrogen and helium. The elemental composition of the collapsing nebula that gave birth ...
