Lee Rannals for redOrbit.com - Your Universe Online A team of astronomers from the UK and Chile have discovered three new planets classified as Super Earths. The planets are part of a group of eight new planets discovered orbiting nearby red dwarf stars. This study shows that virtually all red dwarfs have planets orbiting around them. Astronomers used the High Accuracy Radial Velocity Planet Searcher (HARPS) and Ultraviolet and Visual Echelle Spectrograph (UVES) telescopes for 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...

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...

Billion Ton Asteroid Smashes Into Tiny Star In Puppis Constellation
2014-02-20 13:05:00

[ Watch the Video: Fight Between Tiny Star And Giant Asteroid ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have found evidence that a tiny star 37,000 light-years away from Earth is being bombarded by asteroids. Scientists say PSR J0738-4042, a star located in the constellation of Puppis, has been hit with an asteroid that had a mass of about a billion tons. The team used CSIRO's Parkes Observatory telescope and another telescope in South Africa to make the...

Exoplanet Hunter Selected By European Space Agency
2014-02-20 04:31:01

[ Watch the Video: The Newest Exoplanet Hunter - PLATO ] April Flowers for redOrbit.com - Your Universe Online One of the hottest topics in 21st century science is the exploration of planets around stars other than our own Sun. These planets are known as extrasolar planets, or "exoplanets." One of the key goals of such research is to discover and learn about the properties of Earth-like worlds in the Sun's neighborhood. The European Space Agency (ESA) is preparing a new space mission,...

Exoplanet Search Techniques Needs To Be Refined
2014-02-20 04:11:01

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online There is perhaps no field of astronomical research that more captivates our attention than the search for planets outside our solar system. In the last two decades the planet hunting community has exploded, with hundreds of new planets and planet candidates emerging each year. The holy grail, of course, would be the detection of an Earth-like world. Specifically, astronomers are looking for a planet of similar size to our...

WASP Gives NASA's Planetary Scientists New Observation Platform
2014-02-09 08:10:00

April Flowers for redOrbit.com – Your Universe Online High-altitude balloons have long been used by scientists who study the Earth, the sun and the stars to gain a better view of their targets by carrying their telescopes far into the stratosphere. For planetary scientists, however, this doesn't work, as they need a highly stable, off-the-shelf type system that could accurately point their instruments and then track planetary targets as they move around in the solar system. Such a...

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...

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...

Extrasolar Planet -- An extrasolar planet is a planet orbiting around a star other than the Sun. Extrasolar planets were first discovered in the 1990s as a result of improved telescope technology, CCD and computer-based image processing which allowed far more accurate measurements of stellar motions. The first extrasolar planets were reported by the astronomer Aleksander Wolszczan in 1993, orbiting the pulsar PSR 1257+12. Subsequent investigation has determined that they are only planets...
