NASA’s iROC To Use Lasers To Speed Deep Space Communications
2013-07-09 17:59:38

Brett Smith for redOrbit.com - Your Universe Online With so many far-flung devices still transmitting data back to Earth, NASA scientists said they are working on a system that could be described as part extraterrestrial GPS, part wireless router. The Integrated Radio and Optical Communications project, or iROC, at NASA's Glenn Research Center is being designed to improve the speed and efficiency of data transmission back to Earth via a Mars-orbiting relay station. After receiving...

[ Watch the Video: Proposed 2020 Mars Rover Science Goals ] Lee Rannals for redOrbit.com - Your Universe Online Just last year NASA made an historic landing on the Red Planet with the most advanced rover ever built, Curiosity. Now, the space agency has unveiled plans for a rover in 2020 to extend its reach for Mars even further. NASA released a 154-page document on Tuesday detailing the Mars 2020 mission to look for signs of past life, collect samples to potentially return to Earth,...

Mars Rover Curiosity Heads Toward Mount Sharp
2013-07-09 09:35:45

NASA's Jet Propulsion Laboratory With drives on July 4 and July 7, NASA's Mars rover Curiosity has departed its last science target in the "Glenelg" area and commenced a many-month overland journey to the base of the mission's main destination, Mount Sharp. The rover finished close-up investigation of a target sedimentary outcrop called "Shaler" last week. On July 4, it drove 59 feet (18 meters) away from Shaler. On July 7, a second drive added another 131 feet (40 meters) on the trip...

UK Launches SETI Network

April Flowers for redOrbit.com - Your Universe Online To promote academic research in the UK relating to the Search for Extraterrestrial Intelligence (SETI), a new network has been launched. Academics from 11 institutions across the UK are being brought together by the UK SETI Research Network (UKSRN), whose Patron is the Royal Astronomer, Professor Martin Rees. The network covers a wide range of diverse topics, including potential methods for detecting signals, the linguistic challenge...

Clouds May Help Reveal More Habitable Planets
2013-07-02 05:48:46

April Flowers for redOrbit.com - Your Universe Online According to a new study from the University of Chicago and Northwestern University, the influence of cloud behavior on climate doubles the number of potentially habitable planets orbiting the most common type of stars in the universe, red dwarfs. In the Milky Way alone, the findings suggest, 60 billion planets may be orbiting red dwarf stars in the habitable zone. The study, published in Astrophysical Journal Letters, is based on...

Red Dwarf Stars May Destroy Possibility Of Life In Their Systems
2013-07-01 18:43:05

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Most of the stars in the Universe are classified as red dwarf stars - stars considerably smaller and cooler than our Sun. About 75 percent of the main sequence stars in our galaxy are classified as such, so they represent an exciting population to study in the search for life beyond Earth. If it were found that Earth-like planets formed around red dwarf stars, then the door would be opened to the possibility we might soon...

Louis Del Monte’s webisode references studies and views from prominent physicists to help inquisitive viewers draw their own conclusions. Minneapolis, Minnesota (PRWEB) June 26, 2013 The controversial discussion about extraterrestrial existence has been a pop culture argument for decades. In his newest two-part webisode, “Are Aliens and UFOs Real?” author, physicist and CEO, Louis A. Del Monte shares his views, as well as those of other physicists and legitimate researchers. In part...

Sterilized Mars spacecraft largely a waste of money Two university researchers say environmental restrictions have become unnecessarily restrictive and expensive–on Mars. Writing in the journal Nature Geoscience, astrobiologists Alberto Fairén of Cornell University and Dirk Schulze-Makuch of Washington State University say the NASA Office of Planetary Protection's "detailed and expensive" efforts to keep Earth microorganisms off Mars are making missions to search for...

Three Habitable Super-Earths Discovered In Multi-Planetary Star System

WATCH VIDEOS: [Gliese 667C Planetary Orbits] | [Animation of Gliese 667C System] Lee Rannals for redOrbit.com – Your Universe Online Astronomers have discovered a record-breaking planetary system with at least six planets orbiting its host star. New observations of Gliese 667C show for the first time that three of these six new planet candidates are super-Earths. In order for a planet to qualify as a super-Earth, it must exist within the "habitable zone," which is the zone around...

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...
