Finding An Exoplanet That Takes 80,000 Earth Years To Orbit Its Sun
2014-05-14 05:40:33

Brett Smith for redOrbit.com - Your Universe Online Using observations from multiple observation facilities, an international team of astronomers has identified a very unusual planet that takes around 80,000 Earth years to orbit its sun. The planet, dubbed GU Psc b, was determined to be 2,000 times the distance between the Earth and the Sun from its own star – a new record for exoplanets. The team said they were able to detect this highly unusual planet by detecting the light coming...

Gemini Planet Imager Tracks Down Giant Planet Orbiting Beta Pictoris

Brett Smith for redOrbit.com - Your Universe Online The internationally operated Gemini Observatory has announced the start-up of its new Gemini Planet Imager (GPI), a device designed to capture images of planets outside our Solar System and probe their atmospheres. The imager, which released its first image on Tuesday, was deployed on the observatory’s 8-meter Gemini South telescope in Chile. "Even these early first-light images are almost a factor of 10 better than the previous...

Exoplanet Gassy Earth

John P. Millis, PhD for redOrbit.com - Your Universe Online The holy grail of planet hunting is to find the first Earth-like world. While candidates have been found, there has yet to be confirmation about their particular characteristics. However, a new discovery, made possible by an international team of astronomers, has located the first confirmed Earth-mass planet occulting -- that is, passing in front of -- its host star. Even though the tiny world has the same mass as our planet,...

Scientists May Soon Have New Tools To Answer The 'Are We Alone' Question
2013-09-12 15:23:08

Lee Rannals for redOrbit.com - Your Universe Online Scientists are working on new tools to help detect whether or not life exists on planets far away from our Solar System. Life on Earth is able to send off signals into the atmosphere, such as microbes emitting methane and nitrous oxide. When these chemicals are present in sufficient quantities they become indicators of life and are known as atmospheric biomarkers. Detecting them in the atmosphere of exoplanets could indicate whether or...

Amateur Astronomers Could Be NASA's New Hope For Planet Hunting
2013-09-05 14:16:35

[ Watch the Video: Help NASA Hunt For Exoplanets ] Lee Rannals for redOrbit.com - Your Universe Online NASA's Open Source Differential Photometry Code for Amateur Astronomy Research (OSCAAR) program will allow amateur astronomers to find exoplanets. The US space agency is calling out all amateur astronomers who are seeking to find world's beyond our Solar System. People wanting to get involved who have a telescope will be able to pick up where Kepler left off after a malfunction left...

Super-Jupiter Planet Observed By Astronomers Using the Subaru Telescope
2013-08-06 05:23:10

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online There are several techniques employed by astronomers to discover planets orbiting distant stars. The most popular techniques seek transits - where a planet will pass directly in front of a star, blocking part of its light. Based on the length of the transit, the amount of light that is blocked, and other factors, astronomers can infer a lot of information about the planet. Additionally, researchers will find planets by...

Earth-Like Planets Discovered In Atmospheres Of Dead Stars
2013-05-09 14:38:45

[ Watch the Video: Ring of Rocky Debris Around a White Dwarf Star ] Lee Rannals for redOrbit.com - Your Universe Online The Hubble Space Telescope has helped astronomers spot signs of Earth-like planets in an unlikely place. Astronomers say they found the planets sitting in the atmospheres of a pair of burnt-out stars in a nearby star cluster. The white dwarf stars are being polluted by debris from asteroid-like objects falling onto them, and the researchers say this discovery...

Asteroid Belts Are Good For Life
2012-11-01 14:47:52

Lee Rannals for redOrbit.com - Your Universe Online A new study published in the Monthly Notices of the Royal Astronomical Society suggests the size and location of an asteroid belt may determine whether life can evolve on a planet. An asteroid belt helping to play a role in the development of life may seem counterintuitive, as most view asteroids tend to destroy life. However, the latest study suggests that it is necessary for complex life. The scientists say that the asteroid belt,...

Image 1 - Astronomers Use ALMA To Dissect Nearby Planetary System
2012-04-12 11:46:36

[ Watch the Video ] Astronomers have made a breakthrough discovery in understanding a nearby planetary system, giving clues about how these systems form and evolve. Scientists used the Atacama Large Millimeter/submillimeter Array (ALMA) to find that planets orbiting the star Fomalhaut must be smaller than originally thought. The high-resolution images show that both the inner and outer edges of the thin, dusty disk have very sharp edges.  This, as well as computer simulations,...

Leading Exoplanet Hunters Awarded Science Prize
2012-02-06 04:00:09

Winners are the astronomers behind La Silla´s world-leading HARPS instrument World-renowned Swiss astronomers Michel Mayor and Didier Queloz of the Geneva Observatory have been awarded the 2011 BBVA Foundation Frontiers of Knowledge Award in Basic Sciences for their work on exoplanets. The foundation recognized their groundbreaking efforts in developing “new astronomical instruments and experimental techniques that led to the observation of planets outside the solar...

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...
