Latest HD 189733 Stories

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...

WASHINGTON, June 28, 2012 /PRNewswire-USNewswire/ -- An international team of astronomers using data from NASA's Hubble Space Telescope has made an unparalleled observation, detecting significant changes in the atmosphere of a planet located beyond our solar system. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The scientists conclude the atmospheric variations occurred in response to a powerful eruption on the planet's host star, an event observed by NASA's Swift...

NASA astronomers have successfully demonstrated that a David of a telescope can tackle Goliath-size questions in the quest to study Earth-like planets around other stars. Their work, reported today in the journal Nature, provides a new tool for ground-based observatories, promising to accelerate by years the search for prebiotic, or life-related, molecules on planets orbiting stars beyond our solar system.The scientists reported on a new technique used with a relatively small Earth-based...

Peering far beyond our solar system, NASA researchers have detected the basic chemistry for life in a second hot gas planet, advancing astronomers toward the goal of being able to characterize planets where life could exist. The planet is not habitable but it has the same chemistry that, if found around a rocky planet in the future, could indicate the presence of life."It's the second planet outside our solar system in which water, methane and carbon dioxide have been found, which are...

The U.S. space agency says its Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. The National Aeronautics and Space Administration said the discovery is an important step toward finding chemical biotracers of extraterrestrial life. Although the extrasolar, Jupiter-sized planet called HD 189733b is too hot for life, NASA said the Hubble observations are a proof-of-concept demonstration that the basic chemistry for life can be measured on...

NASA's Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. This is an important step along the trail of finding the chemical biotracers of extraterrestrial life as we know it.The Jupiter-sized planet, called HD 189733b, is too hot for life. But the Hubble observations are a proof-of-concept demonstration that the basic chemistry for life can be measured on planets orbiting other stars. Organic compounds can also be a by-product of life...

NASA's Hubble Space Telescope (HST) has made the first detection ever of an organic molecule in the atmosphere of a Jupiter-sized planet orbiting another star. This breakthrough is an important step in eventually identifying signs of life on a planet outside our solar system.The molecule found by Hubble is methane, which under the right circumstances can play a key role in prebiotic chemistry "” the chemical reactions considered necessary to form life as we know it.This discovery proves...

The NASA/ESA Hubble Space Telescope has given astronomers a fascinating new insight into the atmosphere of a planet in orbit around another star. The observations provide evidence of the presence of hazes in the atmosphere of the planet HD 189733b.A team of astronomers have used the NASA/ESA Hubble Space Telescope to detect, for the first time, strong evidence of hazes in the atmosphere of a planet orbiting a distant star. The discovery comes after extensive observations made recently with...

NASA's Spitzer Space Telescope has detected enough water vapor to fill the oceans on Earth five times inside the collapsing nest of a forming star system. Astronomers say the water vapor is pouring down from the system's natal cloud and smacking into a dusty disk where planets are thought to form. The observations provide the first direct look at how water, an essential ingredient for life as we know it, begins to make its way into planets, possibly even rocky ones like our own. "For the...
