Latest Astrobiology Stories
Man has been looking to the stars and asking the question, "Are we alone?" for as long as recorded history. From H. G. Well's 1897 novel, The War of the Worlds, to the CW's new show, Star Crossed, we have wondered if, and when, aliens might make contact.
NASA's Curiosity Rover has drilled into a slab of Martian sandstone from which portions of rock powder will be delivered into the rover's internal instruments.
In order to avoid potential microbial contamination while searching for signs of microbial life on other planets, research from the International Space Station is being used to analyze the risks of accidentally transporting organisms from Earth into outer space.
A new study from the University of Toronto Scarborough suggests the search for life on planets outside our solar system may be more difficult than previously thought.
The team operating NASA's Curiosity Mars rover plans to proceed in coming days with the third-ever drilling into a rock on Mars to collect a sample for analysis.
NASA has issued a Request for Information (RFI) to science and engineering communities for ideas for a mission to Europa that could address fundamental questions of the enigmatic moon and the search for life beyond Earth.
Curiosity spent this weekend using several of its instruments to inspect a sandstone slab that could become the third drilled rock of the Mars rover’s mission, and the first to consist of something other than mudstone.
A test flight later this week will challenge a set of sensors to map out a 65-yard square of boulder-sized hazards and pick out a safe place to land.
Mysteries of one of the most fascinating nearby planetary systems now have been solved
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.

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...
