Latest Astrobiology Stories
The discovery of biodata encapsulated in molten glass resulting from asteroid and comet impacts millions of years ago not only provides information about the climate and life forms of the ancient Earth, but has also led to hopes that similar preserved organic compounds will be discovered on Mars.
WASHINGTON, April 17, 2014 /PRNewswire-USNewswire/ -- Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" --
A potential game changer in the hunt for life outside our neighborhood has just been discovered about 493 light years away. Using NASA’s Kepler Space Telescope, astronomers have found a rocky planet that is similar in size to Earth
Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers.
The Curiosity science team is analyzing the rock layer surrounding the base of a 16-foot-high butte known as “Mount Remarkable” to determine whether or not the region is a good candidate for investigation using tools on the robotic arm on the Mars rover.
While experts have long believed that life could not exist on planets with a fluctuating tilt in their orbits, new research appearing in the April issue of the journal Astrobiology suggests that such obliquity variations could actually increase the planetary habitability in those worlds.
WASHINGTON, April 15, 2014 /PRNewswire-USNewswire/ -- NASA will host a news teleconference at 2 p.m.
It’s the mystery that has space enthusiasts and the blogosphere buzzing: what exactly is the flash of light that appears on photos taken by NASA’s Mars Curiosity rover earlier this month?
On Wednesday, NASA's Curiosity Mars rover drove the last 98 feet (30 meters) needed to arrive at a site planned since early 2013 as a destination for studying rock clues about ancient environments that may have been favorable for life.
This year the challenges will feature five topics: robotics, space technology, human spaceflight, Earth watch, and asteroids.

In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...
Astrobiology is a peer-reviewed scientific journal published monthly by Mary Ann Liebert Inc. It is the official journal of the Astrobiology Society. As of May 2012, the editor-in-chief is Sherry L. Cady, PhD (Portland State University, Department of Geology). Astrobiology is the leading international journal for astronomers, biologists, chemists, geologists, microbiologists, paleontologists, and planetary scientists designed to advance our understanding of life’s origin, evolution, and...
Carl Edward Sagan (November 9, 1934 - December 20, 1996) was an American astronomer who pioneered exobiology and promoted the Search for Extraterrestrial Intelligence (SETI) and science in general. He is less well known for his skepticism. Born in Brooklyn, New York, Sagan attended the University of Chicago, where he received a bachelor's degree (1955) and a master's degree (1956) in physics, before earning his doctorate (1960) in astronomy and astrophysics. He taught at Harvard University...
Xenobiology -- Xenobiology (or exobiology, or astrobiology) is the term for a speculative field within biology which considers the possibility of, and possible nature of, extraterrestrial life. It also necessarily includes the concept of artificial life, since any life form might naturally evolve elsewhere, could conceivably come out of a laboratory using a future technology. It might be difficult to tell whether a truly strange life form had in fact arisen in space, or was designed much...
Panspermia -- Panspermia is a theory (more directly described as a hypothesis, as there is no compelling evidence yet available to support or contradict it) that suggests that the seeds of life are prevalent throughout the universe and life on Earth began by such seeds landing on Earth and propagating. The theory has origins in the ideas of Anaxagoras, a Greek philosopher. An important proponent of the theory was the British astronomer Sir Fred Hoyle. There is some evidence to...
