ExoMars Rover Testing On Earth Ahead Of 2018 Mission
2014-03-28 12:17:49

Lee Rannals for redOrbit.com - Your Universe Online A giant sand pit that mimics the surface of Mars will be helping test out the ExoMars rover before its trip to the Red Planet in four years. The European Space Agency (ESA) and Russia’s Roscosmos space agency collaborated on the ExoMars rover, which will be launched in 2018. The mission will help address questions about whether life ever existed on Mars by looking at its atmosphere and drilling into the planet’s surface. ESA...

Don’t Forget F-type Stars In The Search For Life
2014-03-27 13:19:34

University of Texas at Arlington Scientists searching for habitable planets beyond Earth shouldn’t overlook F-type stars in favor of their more abundant, smaller and cooler cousins, according to new research from University of Texas at Arlington physicists. Stars fall into seven lettered categories according to their surface temperature, but they also differ in other factors such as mass, luminosity and abundance in the universe. Scientists looking for habitable planets typically...

Lee Rannals for redOrbit.com - Your Universe Online Researchers have designed a simulation chamber that could be used to help prepare for missions to Mars. A team from Centro de Astrobiología, INTA-CSIC, and Instituto de Ciencias de Materials de Madrid created “MARTE” to test out new electromechanical gear for potential Red Planet missions. The vacuum chamber is able to mimic the conditions on Mars, including the planet’s Martian dust. Scientists believe Mars may have once, or...

Researchers in Spain have designed a vacuum chamber capable of mimicking conditions on Mars to test gear for use in future missions WASHINGTON, March 25, 2014 /PRNewswire-USNewswire/ -- A research team in Spain has the enviable job of testing out new electromechanical gear for potential use in future missions to the "Red Planet." They do it within their Mars environmental simulation chamber, which is specially designed to mimic conditions on the fourth planet from the sun -- right...

Sandstone layers with varying resistance to erosion
2014-03-25 06:30:10

Guy Webster, NASA Jet Propulsion Laboratory Variations in the stuff that cements grains together in sandstone have shaped the landscape surrounding NASA's Curiosity Mars rover and could be a study topic at the mission's next science waypoint. On a journey with many months yet to go toward prime destinations on the lower slope of Mount Sharp, Curiosity is approaching a site called "the Kimberley." Scientists on the team picked this location last year as a likely place to pause for...

Fuel Cells May Have Answers To The Rise Of Life
2014-03-14 10:32:15

NASA's Jet Propulsion Laboratory How life arose from the toxic and inhospitable environment of our planet billions of years ago remains a deep mystery. Researchers have simulated the conditions of an early Earth in test tubes, even fashioning some of life's basic ingredients. But how those ingredients assembled into living cells, and how life was first able to generate energy, remain unknown. A new study led by Laurie Barge of NASA's Jet Propulsion Laboratory in Pasadena, Calif.,...

Looking To Geology To Find Answers Of How Life On Earth Originated
2014-03-13 10:20:59

[ Watch the Video: The Origins of Life on Earth ] Brett Smith for redOrbit.com - Your Universe Online By simulating a geologic precursor of cell metabolism, a team of British and American scientists have taken an important step toward understanding how life arose on Earth. Their work is published in a new paper in the journal Astrobiology. “What we are trying to do is to bridge the gap between the geological processes of the early Earth and the emergence of biological life on this...

Kepler Space Telescope Marks Five Years in Space
2014-03-07 11:47:49

NASA's Jet Propulsion Laboratory Exactly five years ago, on March 6, 2009, NASA's Kepler Space Telescope rocketed into the night skies above Cape Canaveral Air Force Station in Florida to find planets around other stars, called exoplanets, in search of potentially habitable worlds. Since then, Kepler has unveiled a whole new side of our galaxy -- one that is teeming with planets. Because of Kepler, we now know that most stars have planets, Earth-sized planets are common, and planets...

Exoplanet Atmospheres
2014-03-05 07:53:33

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The holy grail of planetary astronomy is the search for a potentially habitable planet, or even better, one that is shown to already contain life. There are various parameters that are needed in order to ascertain the habitability of worlds, such as whether liquid water can be sustained on its surface. Recent studies, however, have found that identifying some of these characteristics is rather difficult, and we may in fact...

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...

Sagan, Carl
2004-10-19 04:45:44

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...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
