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.
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 ...
Titan's was atmosphere created by gases escaping the core
A decade ago, a tiny but mighty probe descended into the soupy atmosphere of Titan. This moon of Saturn is of great interest to astrobiologists because its chemistry and liquid cycle remind us of what the ...
Fierce 'superflares' from the sun zapped an infant Earth
Our young sun may have routinely blasted Earth with gobs of energy more powerful than any similar bombardments recorded in human history.
Water-world Earths could host life, even if they're askew
Life could be habitable on an Earth-sized waterworld tilted on its side if the oceans aren't too shallow, a new study reveals.
Could ionized gas do A better job of sterilizing spacecraft?
Earth's microbes are a hardy bunch. They can survive in extreme environments, such as inside hot springs at the bottom of the ocean. Some have even remained alive despite being exposed to the ultraviolet ...
Planets can alter each other's climates over eons
A new study sheds light on how exoplanets in tightly-packed solar systems interact with each other gravitationally by affecting one another's climates and their abilities to support alien life.
Guiding our search for life on other earths
A telescope will soon allow astronomers to probe the atmosphere of Earthlike exoplanets for signs of life. To prepare, Lisa Kaltenegger and her team are modeling the atmospheric fingerprints for hundreds ...
The search for volcanic eruptions on Mars reaches the next level
A new study of emissions from Martian volcanoes suggests there is no activity going on right now, but researchers aren't ruling out recent eruptions.
Planets orbiting red dwarfs may stay wet enough for life
Small, cold stars known as red dwarfs are the most common type of star in the Universe, and the sheer number of planets that may exist around them potentially make them valuable places to hunt for signs of ...
How did multicellular life evolve?
Scientists are discovering ways in which single cells might have evolved traits that entrenched them into group behavior, paving the way for multicellular life. These discoveries could shed light on how complex ...
How can we protect Mars from Earth while searching for life?
The search for life on Mars presents us with many challenges – not the least of which is microbial contamination. How do we ensure that microbes from Earth don't hitchhike all the way to the Red Planet ...
