Artist's View of Extrasolar Planet HD 189733b
This illustration depicts the extrasolar planet HD 189733b with its parent star peeking above its top edge. Astronomers used the Hubble Space Telescope to detect methane and water vapor in the Jupiter-size planet's atmosphere. They made the finding by studying how light from the...
Hubble Finds Building Block of Life on an Extrasolar Planet
The search for life outside of our solar system takes another important step. Detecting an organic molecule in an extrasolar, or XO, planet means that the building blocks of life do exist elsewhere in the universe. Researchers can't be sure how the methane ended up in the...
