Combination of cosmic processes shapes the size and location of sub-Neptunes

A combination of cosmic processes shapes the formation of one of the most common types of planets outside of our solar system, according to a new study.

Webb Directly Images Multiple Giant Exoplanets around Two Young Stars

Astronomers using the Near-Infrared Camera (NIRCam) onboard the NASA/ESA/CSA James Webb Space Telescope have captured coronagraphic images of the HR 8799 and 51 Eridani planetary systems.

New cosmic neighbors: Four planets found just 6 light years away

Exciting new research suggests there are four miniature planets orbiting Barnard's Star, each thought to be just 20 to 30% the mass of Earth.

Speedy white dwarf planets are more likely to be habitable

Speedy’ planets orbiting faster in smaller orbits around white dwarfs are warmer than expected and more likely to maintain habitable conditions than the planets around the sun-like stars.

First 3D observations of an exoplanet's atmosphere reveal a unique climate

The planet, WASP-121b, is some 900 light-years away in the constellation Puppis. The team has now probed deep inside Tylos's atmosphere and revealed distinct winds in separate layers, forming a map of the atmosphere's 3D structure.

James Webb telescope glimpse of young planet

A Canadian-led team of international astronomers has made a groundbreaking discovery about how young planets form and grow using a creative approach with unique tools of the James Webb Space Telescope.

Existence Of Exoplanet HD 20794 d In A Habitable Zone Confirmed

An international team has confirmed the discovery of a super-Earth orbiting in the habitable zone of a nearby Sun-like star.

Astronomers Discover Exoplanets Falling Apart in Space

Astronomers have found two planets around two separate stars that are succumbing to their stars' intense heat. Both are disintegrating before our telescopic eyes, leaving trails of debris similar to a comet's. 

Super-Earth vs. Sub-Neptune? The Winner is Super-Venus

New data from James Webb Space Telescope and simulation models have confirmed a new type of planet unlike anything found in the Solar System.

Record-Shattering 20,000 Mph Winds Detected on Wild Alien Planet

Winds circling a gas giant more than 500 light years from Earth have been detected flowing at supersonic speeds approaching 33,000 kilometers per hour, making them the fastest air currents on any known planet by a wide margin.

Planet's Odd Atmosphere Doesn't Match The Disc It Was Born in

When examining a still-developing exoplanet in a distant star system, a team of astronomers uncovered a mismatch between the gases in the planet's atmosphere and those within the disk.

JWST Discovers A New Planet In The Kepler-51 System

An unusual planetary system with three known ultra-low density "super-puff" planets has at least one more planet.

New hope for an atmosphere on TRAPPIST-1 exoplanet

Data from 2023 soured hopes that a nearby exoplanet had a habitable atmosphere. That disappointment might have been premature.

The Youngest Transiting Exoplanet Ever Detected

A still-forming planet has been detected early in its birth process, thanks to what may have been a chance encounter with a passing star that flipped part of the obscuring disk out of the way, exposing the baby planet.

Nearly a Third of All Stars May Contain The Remains of Planets Like Earth

In recent years, astronomers have developed techniques to measure the metal content of stars with extreme accuracy.
