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.
Leech has a remarkably high tolerance to freezing and thawing
Imagine you're a leech, happily making a living on a turtle in some quiet, freshwater pond. What do you do when winter comes and temperatures in your warm little habitat begins to dip below freezing?
Atmosphere models seek clues for rocky exoplanets
When a distant planet appears as a point of light in a telescope, it's hard to imagine what things are like at the surface. Does rain fall? Is the atmosphere thick, or dissipating into space? How constant ...
Researchers investigate size, depth, and origin of the living subsurface biosphere
The Sun was once thought to provide energy for all life on Earth - meaning that life could not survive without it. In the 20th century, as astrobiologists began to explore the Earth's most remote and harsh ...
How magnetic crustal fields affect planets
If you are ever lost on the surface of Mars, don't count on a compass to help you get home. On Mars, compasses don't work.
How did the Late Heavy Bombardment affect Earth's crust?
Astrobiologists supported by the NASA Astrobiology Institute have assessed the effects of impacts on the crust of the early Earth. The research could help determine whether or not evidence of such violent ...
Comparing the effects of human activities with historic periods of climate change
Researchers supported in part by the NASA Goddard Institute for Space Studies (GISS) have compared the effects of human activities with historic periods of climate change using data collected from wetlands ...
New evidence for ancient ocean on Mars
Did a vast ocean once cover Mars' northern plains? The idea has been hotly debated among scientists for the past 20 years, ever since Viking Orbiter images revealed possible ancient shorelines near the pole. ...
How radiation rules Mars exploration
Nearly everything we know about the radiation exposure on a trip to Mars we have learned in the past 200 days.
MAVEN satellite looks for Mars' missing atmosphere
Ninety kilometers over our heads, the sky is glowing. During the day, the Sun turns the top of our sky into a sea of electrons. They flow over one another without friction, creating plasma. Radio waves that ...
How did early Earth protect itself against the cold?
Earth's Sun was a weakling when it was younger. Around three or four billion years ago, the star's energy was about 20 percent to 25 percent lower than what's experienced today. If that was still true today, ...
A safer recipe for primordial soup
Researchers have published a simpler, safer method for conducting Miller-Urey origin of life experiments—which may still yield new insight about how life began on Earth.
Extraterrestrial Intelligence: The Challenge of Comprehending E.T.'s IQ
Although we often ponder the possible otherworldly morphology of extraterrestrials, a harder exercise is conceiving alien intelligences.
In the eye of the beholder
Astrobiologists are developing 'intelligent' instruments that could help future robotic explorers make their own decisions about where and how to collect data. Although focused on Mars exploration for the ...
Lichen on Mars
Humans cannot hope to survive life on Mars without plenty of protection from the surface radiation, freezing night temperatures and dust storms on the red planet. So they could be excused for marveling at ...
Does a planet need life to create continents?
If not for life, Earth may not have possessed the continents it does now, instead becoming a planet covered nearly entirely in ocean, researchers say.
