NASA Discusses Future Robotic Lander Mission To Europa
2013-08-07 14:22:36

Brett Smith for redOrbit.com - Your Universe Online Jupiter's moon Europa, with its icy surface and potential for a liquid ocean underneath, has fascinated scientists for years and a new NASA-backed report looks at just how an exploratory mission might play out on its surface. The report's authors are describing it as the first step in a process that is expected to take years and cover billions of miles to complete. "If one day humans send a robotic lander to the surface of Europa,...

Mars Rover Curiosity Ends First Year On Mars, Prepares For Year Two
2013-08-04 04:49:35

[ Watch the Video: Twelve Months in Two Minutes - Curiosity's First Year on Mars ] redOrbit Staff & Wire Reports - Your Universe Online This week marks the one-year anniversary of the NASA Curiosity rover's arrival on Mars, and the start of its search for evidence suggesting that the Red Planet was once capable of supporting microbial life. Curiosity, which lifted off from Cape Canaveral Air Force Station's Space Launch Complex 41 in November 2011, touched down in Gale Crater on...

Runaway Greenhouse Planet
2013-07-30 11:42:08

Brett Smith for redOrbit.com - Your Universe Online When a planet absorbs too much solar radiation, its atmosphere reaches a tipping point - overheating, boiling its oceans and filling with steam. The result is an uninhabitable world much like Venus. This 'runaway greenhouse' phenomenon typically occurs just inside the habitable zone orbited by planets like Earth, and a new report in Nature Geoscience indicates that reaching the tipping point may be easier than previously thought....

Curiosity Rover Longest Drive To Date
2013-07-24 10:05:43

Brett Smith for redOrbit.com - Your Universe Online In its continuing mission to survey Mars, NASA's Mars Curiosity rover drove its farthest distance ever on Sunday, the space agency said. NASA engineers took advantage of the rover's previous high vantage point to take Curiosity out for a spin at the start of its 340th Martian day, or sol. The Curiosity team said they will begin using the rover's automatic navigation, or "autonav," program to trace a path across the landscape and drive...

Planets May Keep Warmer In A Cool Star System
2013-07-19 13:49:17

Lee Rannals for redOrbit.com - Your Universe Online According to a new study published in the journal Astrobiology, planets orbiting cooler stars may be more likely to remain ice-free than planets around hotter stars. Stars emit different types of light, with hotter stars emitting high-energy visible and ultraviolet light, and cooler stars giving off infrared and near-infrared light. A new climate model found that planets orbiting cool stars actually may be warmer and less icy than...

Hunting For Exoplanets
2013-07-19 10:34:45

redOrbit Staff & Wire Reports - Your Universe Online The hunt is on for planets that, like Earth, have the conditions necessary for life to survive on their surfaces. But what exactly are scientists looking for? Earlier this week, NASA officials shed a little light on precisely what conditions they are seeking on worlds located beyond our solar system. These worlds, which are also known as exoplanets, have to meet a handful of different criteria in order to be considered potentially...

Mars Atmosphere
2013-07-18 16:00:41

[ Watch the Video: Searching for Mars' Missing Atmosphere ] Lee Rannals for redOrbit.com - Your Universe Online NASA's Curiosity rover has helped bring in some new insights about how Mars lost its original atmosphere. Scientists believe the original Martian atmosphere was much thicker than it is today, leading many to wonder how it became so thin. The Mars Curiosity laboratory has provided some clues into this mystery, which scientists recently reported about in the journal Science....

Curiosity Rover Travels Over One Kilometer
2013-07-17 13:03:43

redOrbit Staff & Wire Reports - Your Universe Online Following its latest drive, the NASA Mars Science Laboratory Curiosity surpassed the one kilometer milestone in distance traveled since it landed on the Red Planet, officials from the US space agency have announced. The latest journey covered approximately 38 meters or 125 feet, bringing the total distance traveled by the rover to 1.029 kilometers or 3,376 feet, NASA said. The drive was completed during the early afternoon hours...

Curiosity Completes Third Drive, Covers 135 Feet In One Day
2013-07-13 07:32:49

April Flowers for redOrbit.com - Your Universe Online On Tuesday, July 9, NASA's Mars rover Curiosity drove 135 feet. This was the third drive of a journey of many months from the "Glenelg" area to Mount Sharp. The mission finished its investigation of science targets in the Glenelg area last week. Glenelg is about 500 yards east of Curiosity's landing site. The next major destination for Curiosity is at the lower layers of Mount Sharp, approximately 5 miles southwest of Glenelg. The...

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...
