The Gemini Planet Imager (GPI), a dedicated planet-finding instrument at the Gemini South telescope in Chile, is concluding a 4-year survey - the GPI Exoplanet Survey (GPIES) - of 531 young, nearby stars searching for giant planets.

Small, hardy planets packed with dense elements have the best chance of avoiding being crushed and swallowed up when their host star dies, new research from the University of Warwick has found.

TESS Finds Its First Earth-sized Planet

A nearby system hosts the first Earth-sized planet discovered by NASA's Transiting Exoplanets Survey Satellite, as well as a warm sub-Neptune-sized world.

In the past three decades, almost 4,000 planet-like objects have been discovered orbiting isolated stars outside the Solar System (exoplanets).

A fragment of a planet that has survived the death of its star has been discovered by University of Warwick astronomers in a disc of debris formed from destroyed planets, which the star ultimately consumes.

Cooking Up Alien Atmospheres On Earth

Researchers at NASA's Jet Propulsion Laboratory in Pasadena, California, are cooking up an alien atmosphere right here on Earth.

New research led by an astronomer at the University of Warwick has found the first confirmed example of a double star system that has flipped its surrounding disk to a position that leaps over the orbital plane of those stars.

Astronomers have found a new exoplanet that could alter the standing theory of planet formation. With a mass that's between that of Neptune and Saturn, and its location beyond the "snow line" of its host star, an alien world of this scale was supposed to be rare.

Hubble Finds a Fast Evaporating Exoplanet

Fishermen would be puzzled if they netted only big and little fish, but few medium-sized fish.

The Stuff That Planets Are Made Of

Is there a second Earth out there in space? Our knowledge of planetary systems far, far away is increasing constantly, as new technologies continue to sharpen our gaze into space.

To answer significant questions about planetary systems, such as whether our solar system is a rare phenomenon or if life exists on planets other than Earth, NASA should lead a large direct imaging mission - an advanced space telescope.

Exoplanets, planets in other solar systems, can orbit very close to their host star.

When it comes to extrasolar planets, appearances can be deceiving. Astronomers have imaged a new planet, and it appears nearly identical to one of the best studied gas-giant planets.

Nestled in the young Ophiuchus star-forming region, 410 light-years from the Sun, a fascinating protoplanetary disc named AS 209 is slowly being carved into shape.

A Hot Jupiter With Unusual Winds

The hottest point on a gaseous planet near a distant star isn't where astrophysicists expected it to be - a discovery that challenges scientists' understanding of the many planets of this type found in solar systems outside our own.

A new, low-cost attachment to telescopes allows previously unachievable precision in ground-based observations of exoplanets -- planets beyond our solar system

Hubble Observes Pitch Black Planet

Astronomers have discovered that the well-studied exoplanet WASP-12b reflects almost no light, making it appear essentially pitch black.

A study combining observations from NASA's Hubble and Spitzer space telescopes reveals that the distant planet HAT-P-26b has a primitive atmosphere composed almost entirely of hydrogen and helium.

Brown Dwarfs Reveal Exoplanets' Secrets

Brown dwarfs are smaller than stars, but more massive than giant planets. As such, they provide a natural link between astronomy and planetary science.

Imagine you want to measure the size of a room, but it's completely dark. If you shout, you can tell if the space you're in is relatively big or small, depending on how long it takes to hear the echo after it bounces off the wall.
