Two Ancient Worlds Discovered In Neighboring Galactic Cluster
2014-06-04 07:02:00

Lawrence LeBlond for redOrbit.com - Your Universe Online Using new data from the HARPS spectrometer at the ESO’s La Silla observatory in Chile, an international team of scientists have discovered two exoplanets orbiting a nearby ancient star. Kapteyn’s star, named after Jacobus Kapteyn, who discovered the star in the 19th century, is a red dwarf and one of the two planets in its grasp sits at the right spot where life could form. Led by Queen Mary University of London, the...

Lick's Automated Planet Finder Has Found Two New Planetary Systems
2014-03-27 12:31:13

By Tim Stephens, UC Santa Cruz In its first months of operation, the APF has found two new planetary systems, giving astronomers a taste of planetary riches to come Lick Observatory's newest telescope, the Automated Planet Finder (APF), has been operating robotically night after night on Mt. Hamilton since January, searching nearby stars for Earth-sized planets. Every night the fully autonomous system checks the weather, decides which stars to observe, and moves the telescope from star...

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,...

Astronomers Discover Seventh Planet Orbiting Nearby Star System
2013-10-25 15:26:17

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have discovered a seventh planet orbiting a dwarf star, known as KIC 11442793, making it the first Kepler planetary system with this many alien worlds. The star is about 2,500 light years from Earth and its planetary system could be a record holder. All seven planets in the system orbit much closer to their host star, meaning the system is very crowded when compared to even our own Solar System. Scientists say that the...

Planetary Building Blocks Found Around White Dwarf Star

[ Watch the Video: Oxygen And Water Evidence From Extrasolar Asteroid? ] redOrbit Staff & Wire Reports - Your Universe Online For the first time, researchers have discovered two essential components required for habitable planets – water and a rocky surface – existing together outside of our solar system. Researchers from the University of Cambridge, the University of Warwick and the University of Kiel report in the latest edition of the journal Science that they had analyzed...

Complex Origins Of Solar Systems
2013-07-25 11:12:46

John P. Millis, PhD for redOrbit.com - Your Universe Online Centuries ago, as astronomers began to discover the extent of our solar system, they also began to develop theories on how our Solar System was formed and how it evolved. The challenge was that the only model available was that of our own - other planetary systems would not be discovered until the later part of the 20th century - so researchers assumed that all solar systems would likely look like ours: central star, small rocky...

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...

Two New Exoplanets Confirmed
2013-04-30 05:08:49

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online The newest addition to our planet-hunting arsenal, the HARPS spectrograph, has characterized two new worlds. Planets KOI-200 b and KOI-889 b are Jupiter-like planets that orbit very close to their host stars. With periods of less than 10 days, the so-called “Hot Jupiters” were originally detected using NASA´s Kepler spacecraft. This instrument has documented more than 800 new exoplanets, with thousands...

Super Earth Found In Habitable Zone Within Lyra Constellation
2013-04-18 13:50:16

Lee Rannals for redOrbit.com — Your Universe Online Astronomers have discovered what could be considered the most Earth-like planet ever found outside our Solar System. The team used the Kepler Space Telescope to find Kepler 62f, a small rocky planet orbiting a Sun-like star in the Lyra constellation. The planet is about 1.4 times the size of Earth, and receives about half as much heat and radiation. Kepler 62f is one of two "super-Earth" planets discovered in the star Kepler...
