A tiny fragment of Martian meteorite 1.3 billion years old is helping to make the case for the possibility of life on Mars, say scientists.
NASA's Mars Curiosity rover has reached the Red Planet's Mount Sharp, a Mount-Rainier-size mountain at the center of the vast Gale Crater and the rover mission's long-term prime destination.
A team of scientists led by Carnegie's Jacqueline Faherty has discovered the first evidence of water ice clouds on an object outside of our own Solar System.
Evaluation of a pale, flat Martian rock as the potential next drilling target for NASA's Curiosity Mars rover determined that the rock was not stable enough for safe drilling.
WASHINGTON, Aug. 19, 2014 /PRNewswire-USNewswire/ -- NASA Television will live broadcast a discussion Wednesday, Aug. 20, from 5:30 to 6:30 p.m.
The team operating NASA's Curiosity Mars rover has chosen a rock that looks like a pale paving stone as the mission's fourth drilling target, if it passes engineers' evaluation. They call it "Bonanza King."
NASA's Low-Density Supersonic Decelerator (LDSD) project successfully flew a rocket-powered, saucer-shaped test vehicle into near-space in late June from the U.S. Navy's Pacific Missile Range Facility on Kauai, Hawaii.
Seven years ago, the Bunburra Rockhole Meteorite fell on the Western Australia side of Nullarbor Plain and was captured on camera. A new study indicates that the unique characteristics of the meteorite suggest it originates from a never-before-identified asteroid.
Researchers are a step closer to understanding the birth of the sun. Published in Science, the team led by Dr Maria Lugaro and Professor Alexander Heger, from Monash University, have investigated the solar system's prehistoric phase and the events that led to the birth of the sun.
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...
