Determining the size of an Earth-size exoplanet by the amount of starlight it blocks hundreds of light-years away once was the realm of science fiction.

They wouldn't float like balloons or give you the chance to talk in high, squeaky voices, but planets with helium skies may constitute an exotic planetary class in our Milky Way galaxy.

NASA's Hubble Space Telescope has detected a stratosphere, one of the primary layers of Earth's atmosphere, on a massive and blazing-hot exoplanet known as WASP-33b.

Extrasolar Planet Weather Forecasts

"Cloudy for the morning, turning to clear with scorching heat in the afternoon."

For the first time, researchers led by the University of Cambridge have detected atmospheric variability on a rocky planet outside the solar system, and observed a nearly threefold change in temperature over a two year period.

Three Super-Earths Orbit HD 7924

We report the discovery of two super-Earth mass planets orbiting the nearby K0.5 dwarf HD 7924 which was previously known to host one small planet. The new companions have masses of 7.9 and 6.4 M⊕, and orbital periods of 15.3 and 24.5 days.

Harvard-Smithsonian Center for Astrophysics NASA's Spitzer Space Telescope has teamed up with a telescope on the ground to find a remote gas planet about 13,000 light-years away, making it one of the most distant planets known.

We examine characteristics of circumbinary orbits in the context of current planet formation scenarios.

The debris disk closest to Earth is the one around the star epsilon Eridani at a distance of 3.2 pc. It is the prime target for detailed studies of a belt of planetesimals left from the early phase of planet formation other than the Kuiper Belt.

Researchers wanting to know more about the influences of multiple stars on exoplanets have come up with a new case study: a planet in a four-star system.

A group of astronomers from the US, Europe, Chile and South Africa have determined that 70,000 years ago a recently discovered dim star is likely to have passed through the solar system's distant cloud of comets, the Oort Cloud.

A team of 21st-century explorers working for the Hunt for Exomoons with Kepler project, based at Harvard University, are searching for exomoons using data from NASA's Kepler mission and the Pleiades supercomputer at the NASA Advanced Supercomputing facility at NASA's Ames Research Center.

Astronomers at the Leiden Observatory and the University of Rochester have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is of enormous proportions, much larger and heavier than the ring system of Saturn.

NASA's Kepler Space Telescope, despite being hobbled by the loss of critical guidance systems, has discovered a star with three planets only slightly larger than Earth.

Orbiting the Earth 353 miles above the ground, the Hubble Space Telescope silently pivots toward its new target. At the same time, flying 93 million miles away in interplanetary space, NASA's Spitzer Space Telescope receives commands to point itself at the same celestial target.

Astronomers from MAD at Universidad de Chile present a viable scenario for the three dimensional geometry of a planet forming system. The finding is based on the discovery of shadows cast by a warped inner disk which bears strong implications for the dynamics of planet formation.

Stunning exoplanet images and spectra from the first year of science operations with the Gemini Planet Imager (GPI) were featured today in a press conference at the 225th meeting of the American Astronomical Society (AAS) in Seattle, Washington.

A NASA-sponsored website designed to crowdsource analysis of data from the agency's Wide-field Infrared Survey Explorer (WISE) mission has reached an impressive milestone.

How many stars like our sun host planets like our Earth? NASA's Kepler Space Telescope continuously monitored more than 150,000 stars beyond our solar system, and to date has offered scientists an assortment of more than 4,000 candidate planets for further study -- the 1,000th of which was recently verified.

NASA's planet-hunting Kepler spacecraft makes a comeback with the discovery of the first exoplanet found using its new mission -- K2.
