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...
Venus and Earth provide astonishingly different views of the evolution of a rocky planet, raising the question of why these two rocky worlds evolved so...
Plate tectonics is a fundamental factor in the sustained habitability of Earth, but its time of onset is unknown, with ages ranging from the Hadean to...
Circumbinary planetary systems contain planets that orbit around two stars in the center instead of just one, like in our Solar System.
An artist’s rendition...
According to quantum mechanics, a vacuum state is populated by virtual particle pairs undergoing spontaneous creation and annihilation processes. These...
NASA’s Kepler space telescope was responsible for the discovery of over 2,700 confirmed extrasolar planets, more than half of the total number of exoplanets...
