Latest Astrobiology Stories
History is filled with accounts of man introducing alien species into a new ecosystem, so a new report coming from Nature News should come as no surprise – the Curiosity rover may have introduced microbes into its surrounding environment on Mars.
Dan Werthimer, who heads Berkeley’s new SETI Research Center, summarized the current efforts to seek out extraterrestrial intelligent life at a hearing held May 21 at the US House of Representatives’ Committee on Science, Space, and Technology.
NASA and its international partners now have the go-ahead to begin construction on a new Mars lander, after it completed a successful Mission Critical Design Review on Friday.
WASHINGTON, May 19, 2014 /PRNewswire-USNewswire/ -- NASA and its international partners now have the go-ahead to begin construction on a new Mars lander after it completed a successful Mission
Portions of powdered rock collected by drilling into a sandstone target last week have been delivered to laboratory instruments inside NASA's Curiosity Mars rover, and the rover will soon drive on toward its long-term destination on a mountain slope.
Colin Pillinger, the British space scientist best known for a failed 2003 attempt to land a spacecraft on Mars, has died at the age of 70, his family and colleagues confirmed to various media outlets on Thursday.
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.
Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. 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...
