Giant planets in our solar system and circling other stars have exotic clouds unlike anything on Earth, and the gas giants orbiting close to their stars -- so-called hot Jupiters -- boast the most extreme.

New evidence shows the first-ever pictures capturing the birth of a pair of planets orbiting the star PDS 70 are in fact authentic.

An international team of researchers, led by astronomers from the University of Amsterdam (the Netherlands), has directly demonstrated the presence of iron in the atmosphere of an exoplanet for the first time.

An international team of astronomers has captured fifteen images of the inner rims of planet-forming disks located hundreds of light years away.

WASP-79b Has Yellow Skies And Iron Rain

The weather forecast for the giant, super-hot Jupiter-size planet WASP-79b is steamy humidity, scattered clouds, iron rain, and yellow skies.

Our solar system has a king. The planet Jupiter, named for the most powerful god in the Greek pantheon, has bossed around the other planets through its gravitational influence.

After spotting a curious pattern in scientific papers -- they described exoplanets as being cooler than expected -- Cornell astronomers have improved a mathematical model to accurately gauge the temperatures of planets from solar systems hundreds of light-years away.

Researchers using ESO's Very Large Telescope (VLT) have observed an extreme planet where they suspect it rains iron.

Some of the extremely low-density, "cotton candy like" exoplanets called super-puffs may actually have rings, according to new research from Carnegie's Anthony Piro and Caltech's Shreyas Vissapragada.

A New Way To Study Exoplanets

A team of scientists using the Low Frequency Array (LOFAR) radio telescope in the Netherlands has observed radio waves that carry the distinct signatures of aurorae, caused by the interaction between a star's magnetic field and a planet in orbit around it.

Astronomers from the University of Warwick have observed an exoplanet orbiting a star in just over 18 hours, the shortest orbital period ever observed for a planet of its type.

A "cold Neptune" and two potentially habitable worlds are part of a cache of five newly discovered exoplanets and eight exoplanet candidates found orbiting nearby red dwarf stars, which are reported in The Astrophysical Journal Supplement Series by a team led by Carnegie's Fabo Feng and Paul Butler.

In 2019, when Wolf Cukier finished his junior year at Scarsdale High School in New York, he joined NASA's Goddard Space Flight Center in Greenbelt, Maryland, as a summer intern. His job was to examine variations in star brightness captured by NASA's Transiting Exoplanet Survey Satellite (TESS) and uploaded to the Planet Hunters TESS citizen science project.

New data from NASA's Hubble Space Telescope have provided the first clues to the chemistry of two of these super-puffy planets, which are located in the Kepler 51 system.

The first evidence of a giant planet orbiting a dead white dwarf star has been found in the form of a disc of gas formed from its evaporating atmosphere.

A surprising analysis of the composition of gas giant exoplanets and their host stars shows that there isn't a strong correlation between their compositions when it comes to elements heavier than hydrogen and helium, according to new work led by Carnegie's Johanna Teske and published in the Astronomical Journal.

Exoplanet 51 Eridani b Directly imaged

An updated visual orbit of the directly-imaged exoplanet 51 Eridani b and prospects for a dynamical mass measurement with Gaia

As planetary systems evolve, gravitational interactions between planets can fling some of them into eccentric elliptical orbits around the host star, or even out of the system altogether.

What does a gestating baby planet look like? New research in Nature by a team including Carnegie's Jaehan Bae investigated the effects of three planets in the process of forming around a young star, revealing the source of their atmospheres.

Liquifying A Rocky Exoplanet

Rocky exoplanets that are around Earth-size are comparatively small, which makes them incredibly difficult to detect and characterise using telescopes.
