Exoplanet Gets Partially Evaporated By Host Star
2012-06-28 14:21:08

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have observed one planet in another solar system, similar to Jupiter, giving off a powerful burst of evaporation after passing by its parent star. Using the Hubble Space Telescope, astronomers saw exoplanet HD 189733b bathe in an intense X-ray radiation after its parent star gave off a violet flare. The team observed the planet with Hubble during early 2010 and late 2011, during which HD 189733b was silhouetting its...

NASA Asking For Help With 'Target Asteroids!' Project
2012-04-20 03:49:20

NASA announced a new project on Wednesday that will enlist help from amateur astronomers to discover near-Earth objects (NEOs). The project, known as "Target Asteroids!", will support NASA's Origins Spectral Interpretation Resource Identification Security - Regolith Explorer (OSIRIS-REx) mission. OSIRIS-REx aims to improve basic scientific understanding of NEOs and is scheduled to launch in 2016. NASA is asking amateur astronomers to help better characterize the population of NEOs,...

Astronomers Discover 'Waterworld' Planet
2012-02-21 14:30:13

Astronomers using NASA's Hubble Space Telescope have discovered a new class of planet, completely enveloped by water. The "waterworld" planet has a thick, steamy atmosphere and is smaller than Uranus but larger than Earth. "GJ1214b is like no planet we know of," Zachory Berta of the Harvard-Smithsonian Center for Astrophysics (CfA) said in a press release. "A huge fraction of its mass is made up of water." The planet is about 2.7 times Earth's diameter, and weighs almost seven times...

Astronomers To Get Sneak Peek Of OSIRIS-REx Target Asteroid

  Every six years, asteroid 1999 RQ 36 nears the Earth - by cosmic standards - and researchers are launching a global observation campaign to learn as much as possible in preparation for the OSIRIS-REx, the first U.S.-led mission to bring back a sample of pristine asteroid material. Astronomers working on the U.S.' first asteroid-sample return mission — the NASA mission named OSIRIS-REx — have begun a months-long observing campaign that is the last chance to study their...

DENVER, May 25, 2011 /PRNewswire/ -- NASA has selected the University of Arizona to lead a sample-return mission to an asteroid. The OSIRIS-REx team is led by Dr. Michael Drake, Director of the University of Arizona's Lunar and Planetary Laboratory. NASA Goddard Space Flight Center in Greenbelt, Md. will manage the mission for NASA. Lockheed Martin (NYSE: LMT) will build the spacecraft. The OSIRIS-REx mission is budgeted for approximately $800 million, excluding the launch vehicle. The...

Discovery opens door to new class of exoplanets A team led by a former postdoctoral researcher in MIT's Department of Earth, Atmospheric and Planetary Sciences and the MIT Kavli Institute for Astrophysics, recently measured the first-ever planetary atmosphere that is substantially enriched in carbon. The researchers found that the carbon-to-oxygen ratio of WASP-12b, an exoplanet about 1.4 times the mass of Jupiter and located about 1,200 light years away, is greater than one. As they report...

WASHINGTON, Dec. 1, 2010 /PRNewswire-USNewswire/ -- A team of astronomers, including two NASA Sagan Fellows, has made the first characterizations of a super-Earth's atmosphere by using a ground-based telescope. A super-Earth is a planet up to three times the size of Earth and weighing up to 10 times as much. The findings, reported in the Dec. 2 issue of the journal Nature, are a significant milestone toward eventually being able to probe the atmospheres of Earth-like planets for signs of...

Any driver who's seen deer silhouetted by the headlights of an oncoming car knows that vital information can be conveyed by the outlines of objects. Building on this concept, University of Florida astronomers have analyzed light passing through the upper atmosphere of the giant planet HD 80606 b, about 190 light years from Earth, and determined that its atmosphere contains the element potassium. "It's wonderful that this method works so well for Jupiter-sized planets," said Knicole...

Astronomers using NASA's Hubble Space Telescope have confirmed the existence of a baked object that could be called a "cometary planet." The gas giant planet, named HD 209458b, is orbiting so close to its star that its heated atmosphere is escaping into space. Observations taken with Hubble's Cosmic Origins Spectrograph (COS) suggest powerful stellar winds are sweeping the cast-off atmospheric material behind the scorched planet and shaping it into a comet-like tail. "Since 2003 scientists...
