The NASA/ESA Hubble Space Telescope has given astronomers a fascinating new insight into the atmosphere of a planet in orbit around another star.
A scorching-hot gas planet beyond our solar system is steaming up with water vapor, according to new observations from NASA's Spitzer Space Telescope.
For the first time, water has been identified in the atmosphere of an extrasolar planet.
NASA's Spitzer Space Telescope has captured for the first time enough light from planets outside our solar system, known as exoplanets, to identify signatures of molecules in their atmospheres.
The powerful vision of NASA's Hubble Space Telescope has allowed astronomers to study for the first time the layer-cake structure of the atmosphere of a planet orbiting another star.
New measurements for three planets outside our solar system indicate their temperatures remain fairly constant â€“ and blazing hot â€“ from day to night, even though it is likely one side of each planet always faces its sun and the other is in permanent darkness.
Astronomers have just discovered a magnetic field on tau Bootis, a star orbited by a giant planet on a close-in orbit: the first ever detection of this kind!
Using a network of small automated telescopes known as HAT, Smithsonian astronomers have discovered a planet unlike any other known world. This new planet, designated HAT-P-1, orbits one member of a pair of distant stars 450 light-years away in the constellation Lacerta.
A NASA-led team of astronomers have used NASA's Spitzer Space Telescope to detect a strong flow of heat radiation from a toasty planet orbiting a nearby star. The findings allowed the team to "take the temperature" of the planet.
Soon after its launch two years ago by the Canadian Space Agency (CSA), Canada's "Humble Space Telescope" started making amazing observations-beyond the capacity of any other Earth- or space-based instrument. MOST, our suitcase-sized space telescope orbiting at 820 km, can fix its gaze upon a single star for up to eight weeks at a time. And with its unique combination of steady observation time and precision pointing, MOST can look for subtle variations in stars that are impossible to observe...
- A gift; a largess; a gratuity; a present; a dole.
