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.

Astronomers have obtained the most detailed 'fingerprint' of a rocky planet outside our solar system to date, and found a planet of two halves: one that is almost completely molten, and the other which is almost completely solid.

A series of images taken between November 2013 to April 2015 with the Gemini Planet Imager (GPI) on the Gemini South telescope in Chile shows the exoplanet β Pic b orbiting the star β Pictoris, which lies over 60 light-years from Earth.

NASA's Spitzer Space Telescope has helped astronomers confirm the discovery of the nearest rocky planet outside our solar system.

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.

An Exoplanet Too Big For Its Star

The Australian discovery of a strange exoplanet orbiting a small cool star 500 light years away is challenging ideas about how planets form.
