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.
Cosmic impacts might help synthesize organic compounds
Bullets of ice shot at high speeds can deposit organic compounds on surfaces they strike. The new findings suggest that comets might, indeed, have helped deliver key ingredients of life to Earth and perhaps ...
How did life become complex, and could it happen beyond Earth?
When astrobiologists contemplate life on nearby planets or moons, they often suggest such life would be simple. Instead of there being some kind of multicellular organism on, say, Jupiter's moon Europa, scientists ...
Observing solar system worlds as if they were distant exoplanets
"It takes one to know one," as the old truism goes. When it comes to unraveling the mysteries of far-off exoplanets, the same holds true—one more reason why astronomers want to thoroughly understand the ...
Astrobiology acupuncture: Collecting data from non-planar surfaces
A team of researchers supported in part by the NASA Astrobiology Program has turned to acupuncture in order to study samples from rough and uneven surfaces, such as rocks and meteorites. Using the technique, ...
Questions of continental crust
Geological processes shape the planet Earth and are in many ways essential to our planet's habitability for life. One important geological process is plate tectonics – the drifting, colliding and general ...
How can we search for life on icy moons such as Europa?
Our solar system is host to a wealth of icy worlds that may have water beneath the surface. The Cassini spacecraft recently uncovered evidence of a possible ocean under the surface of Saturn's moon, Mimas.
Jumping hurdles in the RNA world
Astrobiologists have shown that the formation of RNA from prebiotic reactions may not be as problematic as scientists once thought.
Hot super-Earths help track water-rich atmospheres
As the discovery of planets beyond the Solar System becomes more common, scientists have begun the in-depth study of the atmospheres of these bodies.
A database of enzyme diversity
Scientists have a constructed a new database of the diversity in an enzyme that is used by microorganisms to metabolize sulfur.
Preparing for alien life
At a recent event sponsored by NASA and the Library of Congress, a group of scientists and scholars explored how we might prepare for the inevitable discovery of life beyond Earth.
Why Iceland formed so differently from the gentle early Earth
How do you take the temperature of the Earth billions of years ago? The answer lies in the rocks.
Life's history in iron
A new study examines how Earth's oldest iron formations could have been formed before oxygenic photosynthesis played a role in oxidizing iron.
Life can survive on much less water than you might think
"Follow the water" has long been the mantra of our scientific search for alien life in the Solar System and beyond. We continue seeking conditions where water can remain liquid either on a world's surface ...
Planetary atmospheres a key to assessing possibilities for life
A planetary atmosphere is a delicate thing. On Earth, we are familiar with the ozone hole—a tear in our upper atmosphere caused by human-created chemicals that thin away the ozone. Threats to an atmosphere, ...
ChemCam sheds new light on Yellowknife Bay
New results from the Chemistry & Camera (ChemCam) instrument on NASA's Curiosity rover provide further details about the ancient environment of Yellowknife Bay on Mars. Using data from ChemCam, as well as ...
