NASA Many scientists believe we are not alone in the universe. It's probable, they say, that life could have arisen on at least some of the billions of planets thought to exist in our galaxy alone -- just as it did here on planet Earth. This basic question about our place in the Universe is one that may be answered by scientific investigations. What are the next steps to finding life elsewhere? Experts from NASA and its partner institutions addressed this question on Monday, July 14, at...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Space missions generally fall into three different categories: small, medium, and large. Dull naming conventions aside, the various mission types really tell the story of the scale of the projects. But make no mistake; even “small” missions can have a big impact. Recently, the European Space Agency (ESA) has been focusing more on medium and large-scale projects, but that is all changing. The forthcoming CHaracterising...

Distant Earths May Need Balanced Friction Tides To Support Life
2014-07-10 12:52:42

Gerard LeBlond for redOrbit.com - Your Universe Online Friction generates heat and NASA scientists have developed a computer model that shows how friction may help distant Earth-sized planets survive dangerous orbits. Other star systems commonly house Earth-sized planets. To some, friction heat could be destructive, but given the correct amount of heat, it could be helpful in creating conditions to support life. “We found some unexpected good news for planets in vulnerable orbits....

Planetary System Gliese 581

redOrbit Staff & Wire Reports - Your Universe Online Gliese 581g, described as one of the most Earth-like planets when it was originally discovered four years ago, probably does not exist, researchers from Penn State University and the University of Texas at Austin report in the latest edition of the journal Science. Officially, lead author Paul Robertson of Penn State’s Center for Exoplanets and Habitable Worlds and his colleagues write that the existence of Gliese 581g is...

Potentially Habitable Exoplanet With Earth-Like Temperatures Found
2014-06-27 08:24:53

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have discovered a new, potentially habitable Super-Earth believed to possess temperatures comparable to those found here, but with much larger seasonal shifts, provided the atmosphere is similar to our planet's own. Dr. Robert A. Wittenmyer, a researcher at UNSW Australia specializing in the detection and characterization of extrasolar planets, and his colleagues located the new Super-Earth in orbit around the nearby...

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...

Arecibo and NASA Scientists using Earth-based radar have produced sharp views of a recently-discovered asteroid as it slid safely past our planet. Taken on June 8, 2014, the new views of asteroid 2014 HQ124 are some of the most detailed images of a near-Earth asteroid ever obtained with Arecibo Observatory and Goldstone Solar System Radar. Arecibo, Puerto Rico (PRWEB) June 12, 2014 On Sunday, June 8, 2014, asteroid 2014 HQ124 safely passed Earth a little over three times the distance from...

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...

Exoplanets Come In Three "Neapolitan" Flavors
2014-06-02 03:09:48

Harvard-Smithsonian Center for Astrophysics The planets of our solar system come in two basic flavors, like vanilla and chocolate ice cream. We have small, rocky terrestrials like Earth and Mars, and large gas giants like Neptune and Jupiter. We're missing the astronomical equivalent of strawberry ice cream - planets between about one and four times the size of Earth. NASA's Kepler mission has discovered that these types of planets are very common around other stars. New research...

Potential Life On Red-Dwarf Planets May Be Doomed Due To Harsh Space Weather
2014-06-02 03:34:30

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...

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...

Search for Extra-Terrestrial Intelligence (SETI) -- SETI (pronounced SEH-tee) stands for for Search for Extra-Terrestrial Intelligence. Interstellar travel is a common theme in science fiction stories, but the obstacles to such journeys are in practice enormous. An alternative approach to interstellar exploration is to survey the sky in hopes of finding transmissions from a civilization on a distant planet, but such an effort has obstacles as well. Overview Visiting another...

Radio Telescope -- In contrast to an ordinary telescope, which produces visible light images, a radio telescope "sees" radio waves emitted by radio sources located anywhere in the Universe, typically by means of a large parabolic ("dish") antenna, or arrays of them. The best-known (and largest) radio telescope is in Arecibo, Puerto Rico. A well-known radio telescope being an array of antennae is the Very Large Array (VLA) in Socorro, New Mexico. The largest (100-meter diameter) and most...
