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.
A salty, martian meteorite offers clues to habitability
Life as we know it requires energy of some sort to survive and thrive. For plants, that source of energy is the Sun. But there are some microbes that can survive using energy from chemical reactions. Some ...
How Titan's haze help us understand life's origins
Where did life on Earth come from? There are several theories as to what might have happened. Maybe comets came bearing organic material, or life was transported from another planet such as Mars, or something ...
Scientists detect evidence of 'oceans worth' of water in Earth's mantle
Researchers have found evidence of a potential "ocean's worth" of water deep beneath the United States.
Fossilized marine plankton tell the tale of the end Permian mass extinction
The worst mass extinction the Earth has ever seen occurred 252 million years ago. The boundary of the Permian and Triassic geological periods marked the demise of around 90 percent of marine species and 70 ...
Red dwarf stars might be best places to discover alien life
Red dwarfs are the most common type of star in the universe, and nearly every one of these stars may have a planet located in its habitable zone where life has the best chance of existing, a new study concludes.
Rotation of planets influences habitability
There are currently almost 2,000 extrasolar planets known to us, but most are inhospitable gas giants. Thanks to NASA's Kepler mission, a handful of smaller, rockier planets have been discovered within the ...
Robotic rock climbers could uncover clues to Mars' past
A robot that can scale the faces of steep cliffs might one day help explore Mars and find signs of life. The latest experiments with this "Cliffbot" showed it could help examine places otherwise difficult ...
Exploring Mars in low Earth orbit
In their quest to understand life's potential beyond Earth, astrobiologists study how organisms might survive in numerous environments, from the surface of Mars to the ice-covered oceans of Jupiter's moon, ...
Titan offers clues to atmospheres of hazy planets
When hazy planets pass across the face of their star, a curious thing happens. Astronomers are not able to see any changes in the range of light coming from the star and planet system.
Biomarkers of the deep
Tucked away in the southwest corner of Spain is a unique geological site that has fascinated astrobiologists for decades. The Iberian Pyrite Belt (IPB) in Spain's Río Tinto area is the largest known deposit ...
Bright like a diamond: lasers and compressed carbon recreate Jupiter's core
While missions like the Kepler can tell us quite a bit about other worlds, but to actually look into the heart of a planet we had to put a diamond through a pretty rough road-test. ...
Seeing Earth as an exoplanet: What signs of life are visible?
An extraterrestrial spacecraft lurking in a satellite's orbit near Earth would be able to see city lights and pollution in our atmosphere. But what if it searched for signs of life on Earth from afar?
James Webb and the search for life beyond Earth
Before the invention of the telescope, before every continent was on a map, even before the revelation that Earth was not the center of the Universe, humans have wondered at the possibility of life beyond ...
NASA mission to reap bonanza of earth-sized planets
Set to launch in 2017, NASA's Transiting Exoplanet Survey Satellite (TESS) will monitor more than half a million stars over its two-year mission, with a focus on the smallest, brightest stellar objects.
Brown dwarfs may wreak havoc on orbits of nearby planets, causing desolation
Planets that move around their stars in circular orbits are a better bet for life than those in elongated orbits when it comes to creating habitable climate conditions, according to a new study.
