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...

[ Watch the Video: Artist’s Impression of Ring System Around Chariklo ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers writing in the journal Nature say they have observed a minor planet which contains two rings of ice and pebbles for the first time. Chariklo sits about 1.2 billion miles out in the solar system between Saturn and Uranus, and the minor planet, or asteroid, has been known about for many years. However, this is the first time astronomers discovered...

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...

redOrbit Staff & Wire Reports - Your Universe Online Bad news for those who spent $5 to have a Mars crater named after themselves, a significant other or a beloved pet: the International Astronomical Union (IAU) confirmed on Tuesday that those purchased names will not be allowed to appear on official maps and globes. The naming program, announced last month by science advocacy start-up Uwingu, allowed users to go online and pay $5 for the right to place a moniker on one of the...

NASA's WISE Spacecraft Has Yet To Uncover Planet 'X' Beyond Pluto
2014-03-10 08:36:02

redOrbit Staff & Wire Reports - Your Universe Online While NASA’s Wide-Field Infrared Survey Explorer (WISE) has uncovered thousands of new stars during its multi-year mission, it has been unable to collect any evidence supporting the supposed existence of a large but unseen celestial body believed to be located somewhere beyond Pluto’s orbit. This supposed celestial body is commonly referred to as “Planet X” -- alternatively “Nemesis” or “Tyche." However, despite the...

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...

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...

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...

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
