redOrbit Staff & Wire Reports - Your Universe Online Researchers from University College London and the University of New South Wales have reportedly developed a new, more powerful and more accurate way to detect extraterrestrial life that focuses on methane. Writing in the latest edition of the journal Proceedings of the National Academy of Sciences (PNAS), the study authors explain their development of a new spectrum for hot methane capable of detecting the molecule at...

Two Ancient Worlds Discovered In Neighboring Galactic Cluster

Lawrence LeBlond for redOrbit.com - Your Universe Online Using new data from the HARPS spectrometer at the ESO’s La Silla observatory in Chile, an international team of scientists have discovered two exoplanets orbiting a nearby ancient star. Kapteyn’s star, named after Jacobus Kapteyn, who discovered the star in the 19th century, is a red dwarf and one of the two planets in its grasp sits at the right spot where life could form. Led by Queen Mary University of London, the...

Potential Life On Red-Dwarf Planets May Be Doomed Due To Harsh Space Weather

Harvard-Smithsonian Center for Astrophysics Life in the universe might be even rarer than we thought. Recently, astronomers looking for potentially habitable worlds have targeted red dwarf stars because they are the most common type of star, comprising 80 percent of the stars in the universe. But a new study shows that harsh space weather might strip the atmosphere of any rocky planet orbiting in a red dwarf's habitable zone. "A red-dwarf planet faces an extreme space environment, in...

Brett Smith for redOrbit.com - Your Universe Online History is filled with accounts of man introducing alien species into a new ecosystem, so a new report coming from Nature News should come as no surprise – the Curiosity rover may have introduced microbes into its surrounding environment on Mars. The Nature report mentioned a study presented at this year’s annual meeting of the American Society of Microbiology in Boston that discovered that the 377 strains of bacteria found on the...

New Projects Look To Ramp Up The Search For Intelligent ETs

Lawrence LeBlond for redOrbit.com - Your Universe Online The search for extraterrestrial intelligence (SETI) has been a long yet relatively quiet one. First discussed in 1896 when famed inventor Nikola Tesla claimed that his wireless electrical transmission system could potentially be used to contact beings on Mars, scientists have continually developed increasingly sophisticated instruments over the years to reach out to intelligent life in the cosmos. While we know today that there...

Construction To Begin On New NASA Mars Lander

NASA's Jet Propulsion Laboratory NASA and its international partners now have the go-ahead to begin construction on a new Mars lander, after it completed a successful Mission Critical Design Review on Friday. NASA's Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport (InSight) mission will pierce beneath the Martian surface to study its interior. The mission will investigate how Earth-like planets formed and developed their layered inner structure of core,...

Guy Webster, NASA Jet Propulsion Laboratory Portions of powdered rock collected by drilling into a sandstone target last week have been delivered to laboratory instruments inside NASA's Curiosity Mars rover, and the rover will soon drive on toward its long-term destination on a mountain slope. Other instruments on the rover have inspected the rock's interior exposed in the hole and in drill cuttings heaped around the hole. The target rock, "Windjana," is a sandstone slab within a...

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...
