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...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The holy grail of planetary astronomy is the search for a potentially habitable planet, or even better, one that is shown to already contain life. There are various parameters that are needed in order to ascertain the habitability of worlds, such as whether liquid water can be sustained on its surface. Recent studies, however, have found that identifying some of these characteristics is rather difficult, and we may in fact...

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 Project Allows Citizens To Name All Unnamed Craters On Mars

[ Watch the Video: How Can You Leave Your Mark On Mars? ] Brett Smith for redOrbit.com - Your Universe Online With a population of over 7 billion, leaving your mark on Earth it pretty difficult these days. However, leaving you mark on Mars just got a little easier. For just five bucks, the science advocacy start-up Uwingu is allowing anyone with an internet connection to name one of the 500,000 unnamed craters on Mars after themselves, their loved one, a pet or anything else....

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 Hunter Selected By European Space Agency

[ 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,...

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...

NASA WASHINGTON, Feb. 6, 2014 /PRNewswire-USNewswire/ -- NASA's Kepler space telescope mission will be honored with the National Space Club's preeminent award, the Robert H. Goddard Memorial Trophy, in March. The National Space Club is recognizing Kepler for revolutionizing astrophysics and exoplanet science by expanding the census of planets beyond our solar system and fundamentally altering our understanding of our place in the Milky Way galaxy. The award citation acknowledges the...

Study Gives Insight Into How Skywalker's Tatooine May Have Formed
2014-01-31 13:03:26

Lee Rannals for redOrbit.com - Your Universe Online Tatooine, a fictional planet with two stars that is best known as the home of Luke Skywalker in the Star Wars movie franchise, may not be as farfetched as one might think. Scientists from the University of Bristol studied Tatooine’s real world counterparts: circumbinary planets. These planets, like Kepler-34(AB)b, have an orbit that encompasses two stars, and the latest study gives insight into what Skywalker’s home might have...

Terrestrial Planet -- A terrestrial planet is a planet that is mostly composed of silicate rocks and may or may not have a relatively thin atmosphere. The term is derived from the Greek word for Earth, so an alternate definition would be those planets that are more Earth-like than not. Terrestrial planets are very different from gas giants, which may or may not have solid surfaces and are composed mostly of hydrogen and helium in various physical states. Only one terrestrial planet,...

Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...

Gas Giant
2004-10-19 04:45:41

Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...
