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
2014-06-04 07:02:00

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...

New Projects Look To Ramp Up The Search For Intelligent ETs
2014-05-22 12:11:50

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...

we are not ready for alien contact
2014-05-07 08:28:33

April Flowers for redOrbit.com - Your Universe Online Man has been looking to the stars and asking the question, "Are we alone?" for as long as recorded history. From H. G. Well's 1897 novel, The War of the Worlds, to the CW's new show, Star Crossed, we have wondered if, and when, aliens might make contact. But perhaps we are asking the wrong question. Gabriel G. de la Torre from the University of Cadiz believes we should be asking, "Are we ready?" The SETI was made famous by Carl...

Artist’s impression of the planet Beta Pictoris b
2014-04-30 12:55:00

European Southern Observatory VLT measures the spin of Beta Pictoris b Observations from ESO’s Very Large Telescope (VLT) have, for the first time, determined the rotation rate of an exoplanet. Beta Pictoris b has been found to have a day that lasts only eight hours. This is much quicker than any planet in the Solar System — its equator is moving at almost 100,000 kilometers per hour. This new result extends the relation between mass and rotation seen in the Solar System to...

Search For Life On Exoplanets May Be More Difficult Than Previously Thought
2014-04-30 03:25:19

Don Campbell, University of Toronto Scarborough A new study from the University of Toronto Scarborough suggests the search for life on planets outside our solar system may be more difficult than previously thought. The study, authored by a team of international researchers led by UTSC Assistant Professor Hanno Rein from the Department of Physical and Environmental Science, finds the method used to detect biosignatures on such planets, known as exoplanets, can produce a false positive...

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...
