Using data from NASA's Kepler space telescope, a team of researchers, led by astronomers at San Diego State University, detected the new Neptune-to-Saturn-size planet orbiting between two previously known planets.

Astronomers who study stars are providing a valuable assist to the planet-hunting astronomers pursuing the primary objective of NASA's new TESS mission.

Icy Giant Planets In The Laboratory

Giant planets like Uranus and Neptune may contain much less free hydrogen than previously assumed.

Some of the peculiar aspects of our solar system -- an enveloping cloud of comets, dwarf planets in weird orbits and, if it truly exists, a possible Planet Nine far from the sun -- have been linked to the close approach of another star in our system's infancy flung things helter-skelter.

An international team including five Carnegie astronomers has discovered a frozen Super-Earth orbiting Barnard's star, the closest single star to our own Sun.

Astronomers from the Department of Physics at the University of Tokyo discovered a dense disk of material around a young star, which may be a precursor to a planetary system.

Forty-four planets in solar systems beyond our own have been unveiled in one go, dwarfing the usual number of confirmations from extrasolar surveys, which is typically a dozen or less.

An international team of astronomers headed by Dutch researchers from Leiden University has coincidently found a small companion around the young double star CS Cha.

The SPHERE instrument on ESO's Very Large Telescope (VLT) in Chile allows astronomers to suppress the brilliant light of nearby stars in order to obtain a better view of the regions surrounding them.

Transiting Exoplanet Survey Satellite is undergoing final preparations for its April 16 launch to find undiscovered worlds around nearby stars, providing targets where future studies will assess their capacity to harbor life.

A hot, metallic, Earth-sized planet with a density similar to Mercury - situated 339 million light years away -- has been detected and characterised by a global team of astronomers, including the University of Warwick.

In its search for exoplanets -- planets outside of our solar system -- NASA's Kepler telescope trails behind Earth, measuring the brightness of stars that may potentially host planets.

Our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler-90, a Sun-like star 2,545 light years from Earth. The planet was discovered in data from NASA's Kepler Space Telescope.

Taking a picture of an exoplanet--a planet in a solar system beyond our sun--is no easy task.

We report the discovery of OGLE-2016-BLG-1190Lb, which is likely to be the first Spitzer microlensing planet in the Galactic bulge/bar, an assignation that can be confirmed by two epochs of high-resolution imaging of the combined source-lens baseline object.

An Exoplanet With Titanium Oxide Snow

NASA's Hubble Space Telescope has found a blistering hot planet outside our solar system where it "snows" sunscreen.

Planets Form From Comets

Narrow dense rings of comets are coming together to form planets on the outskirts of at least three distant solar systems, astronomers have found in data from a pair of NASA telescopes.

An Inferno World With Titanium Skies

A team of astronomers led by Elyar Sedaghati, an ESO fellow and recent graduate of TU Berlin, has examined the atmosphere of the exoplanet [WASP-19b] in greater detail than ever before.

Scientists have discovered the strongest evidence to date for a stratosphere on a planet outside our solar system, or exoplanet. A stratosphere is a layer of atmosphere in which temperature increases with higher altitudes.

One night three months ago, Rosa Castro finished her dinner, opened her laptop, and uncovered a novel object that was neither planet nor star.
