The space-based TESS satellite that uses the transit method to measure the small drops of a stellar light when an exoplanet passes in front of…
New research redefines the Habitable Zone of exoplanets by considering subglacial liquid water, extending potentially habitable conditions beyond traditional boundaries. Supported by recent JWST observations,…
An amusing rendition of the TOI-1136 system if each body in the system were a duck or duckling. Credit: Rae Holcomb/UCI Six-exoplanet system offers glimpse…
Astronomers using Hubble have detected water vapor in the atmosphere of GJ 9827d, a small exoplanet, suggesting the presence of water-rich atmospheres on similar planets.…
Astrophysicists studying the exoplanet WASP-69b have discovered it possesses a comet-like tail, seven times longer than the planet itself. This phenomenon occurs as the planet’s…
Researchers have identified HD 63433d, an Earth-sized planet that is both closer and younger than previously discovered planets of similar size. Its proximity to a…
The graphic shows the diamond rain inside the planet, which consists of diamonds sinking through the surrounding ice. Pressure and temperature continuously increase on the…
Artistic concept of the exoplanet WASP-107b and its parent star. Even though the rather cool host star emits a relatively small fraction of high-energy photons,…
Astronomers analyzed HAT-P-18 b using the James Webb Space Telescope, revealing water vapor and CO2 in its atmosphere. They highlighted the challenges of distinguishing between…
NASA’s Cassini spacecraft captured this image of Enceladus on November 30, 2010. The shadow of the body of Enceladus on the lower portions of the…
This artist’s impression shows a gas giant exoplanet orbiting a sun-like star, exemplified by Kepler-1625b. Credit: NASA Discovery of giant exomoons around the planets Kepler-1625b…
Researchers conducted a novel study on the runaway greenhouse effect, revealing how a critical threshold of water vapor can lead to catastrophic climate changes on…
ESA’s Cheops mission has revealed a rare six-planet system in orbital resonance around the star HD110067, offering valuable insights into planetary system evolution. This discovery…

An international team of astronomers used the CHEOPS and TESS satellites to discover a system of six planets orbiting the star HD110067 in a unique…
This artist’s concept shows the European Space Agency’s ARIEL spacecraft on its way to Lagrange Point 2 (L2) — a gravitationally stable, Sun-centric orbit —…
Penn State researchers have discovered an extraordinarily massive planet orbiting an ultracool dwarf star, challenging existing theories of planet and star formation. Named LHS 3154b,…
