The tunable laser spectrometer in the SAM (Sample Analysis at Mars) instrument of the Curiosity robot has unequivocally detected an episodic increase in the concentration of methane in Mars' atmosphere after an exhaustive analysis of data obtained during 605 soles or Martian days.
NASA's voyage to Europa might be our last chance to find alien life on the Jovial moon.
Samples obtained by the Mars Rover Curiosity during recent drilling activity appear to indicate that acidic conditions were once present in the region of the Red Planet known as Mount Sharp, officials from NASA’s Jet Propulsion Laboratory revealed on Thursday.
We may not yet be able to assume that intelligent-life exists on other planets, but a team of Australian scientists are confident there are plenty of planets within our galaxy capable of supporting it--hundreds of billions of “Earth-like” planets, in fact.
Planets capable of supporting life could start out as gaseous worlds similar to Neptune, only to be transformed by the combination of two phenomena that individually can inhibit their potential habitability, University of Washington astronomers have discovered in a new study.
Curiosity is back in action following a recent software upgrade, conducting a mini-drill test to make sure that a rock target called Mojave2 is suitable for drilling at full-depth.
Astronomers have discovered the oldest known planetary system ever – a star that is more than 11 billion years old and orbited by at least five rocky planets that are all smaller than Earth.
Finding the next earth just got one step easier. A new NASA instrument designed to study dust in the so-called habitable zone around a star may help future missions centered around capturing images of planets similar to Earth.
A new program will allow NASA scientists to virtually work on location on Mars, walking around on the surface of the Red Planet and conduct science operations along with the Curiosity rover thanks to new Microsoft-developed wearable technology.
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...
