Astronomers Given A Better Ruler In The Search For Extrasolar Planets
2014-03-31 08:04:47

NIST Researchers at the National Institute of Standards and Technology (NIST) have rejuvenated a technique for finding planets near distant stars. New measurements of light from special lamps could help astronomers find planets hidden in data from more than a decade's worth of extrasolar planet searches, as well as improve telescopes' current capabilities. Finding extrasolar planets is tricky. Seen through a telescope, planets in the "habitable zone"—a region close to a star, where...

Lick's Automated Planet Finder Has Found Two New Planetary Systems
2014-03-27 12:31:13

By Tim Stephens, UC Santa Cruz In its first months of operation, the APF has found two new planetary systems, giving astronomers a taste of planetary riches to come Lick Observatory's newest telescope, the Automated Planet Finder (APF), has been operating robotically night after night on Mt. Hamilton since January, searching nearby stars for Earth-sized planets. Every night the fully autonomous system checks the weather, decides which stars to observe, and moves the telescope from star...

Watch The Video: Studying Other Worlds with the Help of a Starshade ] Whitney Clavin, NASA's Jet Propulsion Laboratory A spacecraft that looks like a giant sunflower might one day be used to acquire images of Earth-like rocky planets around nearby stars. The prototype deployable structure, called a starshade, is being developed by NASA's Jet Propulsion Laboratory in Pasadena, Calif. The hunt is on for planets that resemble Earth in size, composition and temperature. Rocky...

Arecibo Observatory Repairs

Ongoing Science Research Back to Full Capacity MENLO PARK, Calif., March 12, 2014 /PRNewswire/ -- On January 13, 2014, the William E. Gordon radio telescope in Arecibo, Puerto Rico sustained damage following a 6.4 magnitude earthquake that was centered 37 miles northwest of Arecibo. Following the earthquake, Arecibo Observatory staff conducted a structural survey that revealed serious damage to a main suspension cable section, with apparent breach of several cable strands within that...

Kepler Space Telescope Marks Five Years in Space
2014-03-07 11:47:49

NASA's Jet Propulsion Laboratory Exactly five years ago, on March 6, 2009, NASA's Kepler Space Telescope rocketed into the night skies above Cape Canaveral Air Force Station in Florida to find planets around other stars, called exoplanets, in search of potentially habitable worlds. Since then, Kepler has unveiled a whole new side of our galaxy -- one that is teeming with planets. Because of Kepler, we now know that most stars have planets, Earth-sized planets are common, and planets...

redOrbit Staff & Wire Reports - Your Universe Online A team of researchers from the University of Arizona’s Department of Astronomy have managed to use an Earth-based telescope to capture images of a world outside of our solar system, according to research scheduled to be published in an upcoming edition of The Astrophysical Journal. The telescope used essentially the same type of imaging sensor found in a standard digital camera instead of an infrared detector, and while the...

New Austrian Study Suggests Super-Earths Are Unfit For Life

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The last two decades have brought unprecedented understanding of worlds outside of our solar system. The launch of the Kepler space telescope and other instruments have allowed astronomers to find and characterize hundreds of new planets, with thousands more candidates waiting to be confirmed. As our technology continues to improve, we will be able to isolate smaller and smaller planets, eventually identifying Earth-sized...

WASHINGTON, Feb. 26, 2014 /PRNewswire-USNewswire/ -- NASA's Kepler mission announced Wednesday the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Nearly 95 percent of these planets are smaller than Neptune, which is almost four times the size of Earth. This discovery marks a significant increase in the number of known small-sized...

NASA's Kepler Mission Has Discovered 715 New Exoplanets

Lee Rannals for redOrbit.com - Your Universe Online NASA announced on Wednesday that its Kepler mission has discovered 715 new planets orbiting 305 stars. The space agency said that 95 percent of the newly discovered worlds are smaller than Neptune, which is about four times the size of Earth. NASA added that this discovery marks an increase in the number of known small-sized planets that are similar to Earth than any previously identified exoplanets. "The Kepler team continues to...

Exoplanet Orbiting Tau Bootis Star Could Have Watery Atmosphere

[ Watch the Video: Watery Evidence Found In Tau Bootis System ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers, publishing a paper in The Astrophysical Journal Letters, say they may have discovered water on an exoplanet outside our solar system. The team of scientists say they believe they have detected water in the atmosphere of a planet orbiting the nearby star tau Boötis. "Planets like tau Boötis b, which are as massive as Jupiter but much hotter, do not...

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...
