Latest Astrobiology Stories
There’s a new hope for Star Wars fans dreaming of a rocky planet that orbits a binary star like Luke Skywalker’s homeworld of Tatooine: astrophysicists from the University of Utah and the Smithsonian Astrophysical Observatory say that such a planet could theoretically exist.
GREENBELT, Md., March 24, 2015 /PRNewswire-USNewswire/ -- A team using the Sample Analysis at Mars (SAM) instrument suite aboard NASA's Curiosity rover has made the first detection of nitrogen
The first “wet chemistry” experiment conducted by NASA’s Curiosity rover may have found evidence of long-chain carboxylic acid, a fatty acid that could be the latest organic molecule to be discovered on Mars, researchers from the US space agency have revealed.
Good news! Experts have analyzed thousands of exoplanets in our galaxy and the calculations show that billions of those stars could have planets in the habitable zone.
Add Enceladus to the growing list of candidates that may be capable of supporting life, as an international team of researchers has discovered evidence of an active hydrothermal system on the icy Saturn moon that could be capable of supporting microbial life.
Astronomers just can't decide on whether GJ 581d, a super-Earth planet, is real or if it is just 'noise.'
WASHINGTON, March 5, 2015 /PRNewswire-USNewswire/ -- A primitive ocean on Mars held more water than Earth's Arctic Ocean, according to NASA scientists who, using ground-based observatories,
A primitive ocean on Mars held more water than Earth’s Arctic Ocean, according to NASA scientists who, using ground-based observatories, measured water signatures in the Red Planet’s atmosphere.
NASA's Curiosity Mars rover is expected to remain stationary for several days of engineering analysis following an onboard fault-protection action on Feb. 27 that halted a process of transferring sample material between devices on the rover's robotic arm.
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.
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...
- A handkerchief.
- Specifically— The legendary sweat-cloth; the handkerchief of St. Veronica, according to tradition miraculously impressed with the mask of Christ; also, the napkin about Christ's head (Johu xx. 7).
- In general, any miraculous portrait of Christ.
