Three Habitable Super-Earths Discovered In Multi-Planetary Star System
2013-06-25 10:50:04

WATCH VIDEOS: [Gliese 667C Planetary Orbits] | [Animation of Gliese 667C System] Lee Rannals for redOrbit.com – Your Universe Online Astronomers have discovered a record-breaking planetary system with at least six planets orbiting its host star. New observations of Gliese 667C show for the first time that three of these six new planet candidates are super-Earths. In order for a planet to qualify as a super-Earth, it must exist within the "habitable zone," which is the zone around...

Light Sunny Super Earth Discovered
2013-06-12 13:29:54

Lee Rannals for redOrbit.com - Your Universe Online Researchers writing in the Astrophysical Journal say they have discovered one very light and sunny super-Earth. Dubbed GJ3470b, the team says the planet is about 14 times the mass of our own planet but is the second lightest of the existing exoplanets that have already been surveyed. Their data revealed that this planet is most likely not covered by thick clouds but is a place where sunscreen would be a necessity. GJ3470b orbits its...

Kickstarter Telescope Campaign Expanded By Planetary Resources
2013-06-12 07:53:41

Lee Rannals for redOrbit.com - Your Universe Online Planetary Resources, a company best known for its plans to mine asteroids, is launching an expanded crowdfunding campaign through Kickstarter. The company recently announced its plans to have the public's help to fund its ARKYD space telescope. Planetary Resources has since added plans to enhance the telescope technology to enable it to search for alien planets around distant stars. These upgrades would add exoplanet transit detection...

New Planet Hunting Technique
2013-06-10 12:43:01

Lee Rannals for redOrbit.com - Your Universe Online Sponsored by the International Astronomical Union (AIU), a team of astronomers is working on a technique capable of detecting faint dust clouds around other stars where Earth-like planets could be hiding. This new technology could dramatically improve the odds of discovering planets with conditions suitable for life. "Current technology allows us to detect only the brightest clouds, those that are a few thousand times brighter than the...

Researchers Look At Hot Jupiters And Planetary Migration
2013-06-07 07:20:56

April Flowers for redOrbit.com — Your Universe Online Stars have an alluring pull on the planets that surround them, especially a class of planets known as hot Jupiters. These planets are gas giants that form farther from their stars before migrating inward and heating up. Hot Jupiters, despite their close-in orbits, are not regularly consumed by their stars, as a new study conducted with data from NASA´s Kepler Space Telescope reveals. These planets remain in fairly stable...

KELT Discovers Metal-poor Cousin Of Famous Planet
2013-06-05 13:43:05

University of Louisville A scientific team led by University of Louisville doctoral student Karen Collins has discovered a hot Saturn-like planet in another solar system 700 light-years away. Collins announced the discovery of exoplanet KELT-6b Tuesday, June 4, during the American Astronomical Society's national meeting in Indianapolis. Astronomers caught sight of the planet when it passed in front of, or "transited," its host star–and they've since discovered that the planet...

Stars And Planets Larger Than Thought Kepler
2013-06-04 13:36:00

Lee Rannals for redOrbit.com - Your Universe Online Astronomers writing in the Astrophysical Journal say they have found that many of the stars and planets discovered are larger than previously thought. The astronomers used the NOAO Kitt Peak National Observatory Mayall 4-meter telescope to observe candidate planets identified by the NASA Kepler Mission and found that most of the stars observed are larger than originally thought, and a quarter of them were 35 percent bigger....

Low-Budget Ground Telescope Pinpoints Gas Giant Exoplanet
2013-06-04 13:45:19

Lee Rannals for redOrbit.com — Your Universe Online Scientists announced during the American Astronomical Society´s (AAS) national meeting in Indianapolis this week that they have discovered a hot Saturn-like planet in another solar system 700 light-years away. The team used an inexpensive ground-based telescope to discover KELT-6b, which resides in the constellation Coma Berenices near Leo. This exoplanet has an orbit that transits its star every 7.8 days. Because of the...

Electrifying Exoplanets With Stellar Winds
2013-06-04 11:10:37

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online When scientists began seeking out planets outside of our solar system, they anticipated seeing systems much like our own. Small, rocky worlds orbiting a couple of astronomical units from the host star, with the gas giant planets orbiting farther out. After all, much effort had been given to explaining how a solar system such as ours would form. Only, this is not what has been found. Many solar systems are constructed...

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...
