Sediments deposited in a large lake bed over tens of millions of years were responsible for the creation of Mount Sharp on Mars, according to observations conducted by NASA’s Curiosity Rover in Gale Crater.
Among the billions and billions of stars in the sky, where should astronomers look for infant Earths where life might develop?
Planets orbiting close to low-mass stars — easily the most common stars in the universe — are prime targets in the search for extraterrestrial life.
WASHINGTON, Dec. 3, 2014 /PRNewswire-USNewswire/ -- NASA will host a media teleconference at noon EST Monday, Dec. 8, to discuss geological observations made by NASA's Mars rover Curiosity.
An international team of scientists, using data from a Martian meteorite, reports that life on Mars is more likely than previously thought.
NASA's Curiosity Mars rover has completed a reconnaissance "walkabout" of the first outcrop it reached at the base of the mission's destination mountain and has begun a second pass examining selected rocks in the outcrop in more detail.
NASA's InSight mission has begun the assembly, test and launch operations (ATLO) phase of its development, on track for a March 2016 launch to Mars.

Weather, which changes day-to-day due to constant fluctuations in the atmosphere, and climate, which varies over decades, are familiar. More recently, a third regime, called “macroweather,” has been used to describe the relatively stable regime between weather and climate.
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...
