WASHINGTON, April 17, 2014 /PRNewswire-USNewswire/ -- Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" -- the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun. http://photos.prnewswire.com/prnvar/20081007/38461LOGO While planets...

Astronomers Using Kepler Telescope Discover First Earth-Sized Exoplanet Within The Habitable Zone

[ Watch the Video: Kepler Discovers First Earth-Sized Exoplanet In Habitable Zone ] Lawrence LeBlond for redOrbit.com - Your Universe Online A potential game changer in the hunt for life outside our neighborhood has just been discovered about 493 light years away. Using NASA’s Kepler Space Telescope, astronomers have found a rocky planet that is similar in size to Earth and is within the “habitable zone” of the star it orbits. The discovery of this planet, called Kepler-186f,...

Tilted orbits

redOrbit Staff & Wire Reports - Your Universe Online While experts have long believed that life could not exist on planets with a fluctuating tilt in their orbits, new research appearing in the April issue of the journal Astrobiology suggests that such obliquity variations could actually increase the planetary habitability in those worlds. According to Weber State University physics professor John Armstrong, University of Washington astronomer Rory Barnes and their colleagues, these...

Saturn's Hexagon: An amazing Phenomenon
2014-04-15 10:10:02

Universidad del País Vasco Researchers of the University of the Basque Country reveal some of the secrets of Saturn's mysterious hexagonal wave, including its rotation period, which could be that of the planet itself In 1980 and 1981 NASA's Voyager 1 and 2 space probes passed for the first time over the planet Saturn, located 1,500 million km from the Sun. Among their numerous discoveries they observed a strange, hexagon-shaped structure in the planet's uppermost clouds surrounding its...

2014 Carl Sagan Fellows
2014-04-03 03:00:40

NASA/JPL NASA has selected seven scientists as recipients of the 2014 Carl Sagan Exoplanet Postdoctoral Fellowships. The fellowship, named for the late astronomer, was created to inspire the next generation of explorers seeking to learn more about planets, and possibly life, around other stars. The primary goal of the fellowship program is to support outstanding recent postdoctoral scientists in conducting independent research related to the science goals of NASA's Exoplanet Exploration...

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...

Don’t Forget F-type Stars In The Search For Life
2014-03-27 13:19:34

University of Texas at Arlington Scientists searching for habitable planets beyond Earth shouldn’t overlook F-type stars in favor of their more abundant, smaller and cooler cousins, according to new research from University of Texas at Arlington physicists. Stars fall into seven lettered categories according to their surface temperature, but they also differ in other factors such as mass, luminosity and abundance in the universe. Scientists looking for habitable planets typically...

Lee Rannals for redOrbit.com - Your Universe Online Scientists have redefined the edge of the Solar System with the discovery of a new distant dwarf planet. The scientists reported in the journal Nature this week that they found 2012 VP113 sitting beyond the known edge of the Solar System. The new dwarf planet is one of thousands of distant objects believed to have formed in the inner Oort cloud. Not only does this new discovery bring into question the currently defined edge of the...

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...

Planetary and Space Science
2012-05-28 10:21:45

Planetary and Space Science is a peer-reviewed scientific journal established in 1959 and published by Elsevier 15 times per year. As of May 2012, the editor-in-chief is Rita Schulz (The Netherlands). The journal publishes original research articles and short communications. The main focus is on solar system processes which encompass multiple areas of the natural sciences. Research that involves planetary and space sciences involves many disciplines. Celestial mechanics is part of these...

Terraforming -- Terraforming (literally, "Earth-shaping") is the process of modifying a planet, moon or other body to a more habitable atmosphere, temperature or ecology. The term was first used in a science fiction novel, 'Seetee Shock' (1940?) by Jack Williamson, but the actual concept is older than that. An example in fiction is 'First and Last Men' by Olaf Stapledon in which Venus is modified, after a long and destructive war with the original inhabitants, who naturally object to the...

Cosmogony -- Cosmogony is the study of the origins of celestial objects. It is most commonly used to refer to the study of the origin of the solar system. Currently, the most widely accepted theory is that the solar system was formed roughly 5 billion years ago with the collapse of a nebula of gas and dust, likely caused by shock waves generated by a nearby supernova. The solar system would have formed as a member of a star cluster, now long-since dispersed throughout the Milky Way over...

Terrestrial Planet Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
