The collision between two exoplanets of several to tens of Earth masses occurred at a distance of 2-16 AU (astronomical units) from the young solar-like...
TRAPPIST-1 is a nearby system of seven Earth-sized, temperate, rocky exoplanets transiting a Jupiter-sized ultracool red dwarf, ideally suited for in-depth...
Lava worlds are a potential emerging population of hot super-Earth exoplanets that are on close-in orbits around their host stars, with likely partially...
HIP 81208 is the first binary stellar system with substellar companions around each stellar component ever found by direct imaging.
Astronomers thought...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered carbon dioxide and methane in the atmosphere of the habitable zone exoplanet...
Astronomers believe the peculiar composition of the Neptune-sized planet TOI-1853b is the result of a giant planetary clash.
Heavy elements dominate the...
Astronomers report the discovery and validation of two long-period giant exoplanets orbiting the K-dwarf star TOI-4600, first detected using observations...
Chromium hydride is often used to probe atmospheric temperatures and classify objects called brown dwarfs into spectral types because it’s abundant only...
Using data from TRAPPIST-South/North, SPECULOOS, and MuSCAT3 facilities, astronomers have discovered an unusual Jupiter-sized exoplanet orbiting the red...
A process called photoevaporation is a potential explanation for several features within exoplanet demographics. Atmospheric escape observed in young Neptune-sized...
The formation of giant planets has traditionally been divided into two pathways: core accretion and gravitational instability. However, in recent years,...
Terrestrial and sub-Neptune exoplanets are expected to form in the inner regions of protoplanetary disks around their parent stars. Water plays a key role...
PDS 70, a young K7-type star some 370 light-years away from Earth in the constellation of Centaurus, is a unique target for planetary formation studies...
Aside from the Moon, the brightest object in our night sky is planet Venus, whose thick cloud layer reflects around 75% of the Sun’s light. By comparison,...
The giant exoplanet AF Leporis b orbits a 1.2-solar-mass star in the 24-million-year-old beta Pictoris moving group.
The direct image of the giant exoplanet...
The giant planet 8 Ursae Minoris b (also known as Halla) orbits the core-helium-burning red giant star 8 Ursae Minoris (Baekdu). At a distance of only...
Planets form in dusty, gas-rich circumstellar disks around young stars, while at the same time, the planet formation process alters the physical and chemical...
The vital role of a carbon molecule called methyl cation (CH3+) in interstellar carbon chemistry was predicted in the 1970s, but the unique capabilities...
Seven rocky planets orbit the nearby dwarf star TRAPPIST-1, providing a unique opportunity to search for atmospheres on small planets outside the Solar...
