TESS detects new ‘hot Jupiter’ exoplanet orbiting a rapidly rotating star

An international team of astronomers has discovered a new "hot Jupiter" exoplanet. They have used NASA's Transiting Exoplanet Survey Satellite (TESS) to make this discovery. The newly discovered alien world is estimated to be nearly three times the mass of Jupiter. The exoplanet orbits...

James Webb Space Telescope reveals an exoplanet atmosphere as never seen before

NASA's space telescope has created a molecular and chemical portrait of exoplanet WASP-39 b's atmospheric constituents. It is a Saturn-sized giant orbiting a star 700 light-years away. The observations include atoms and molecules, as well as evidence of active chemistry and clouds. The discoveries...

ESA demonstrates the first tests of exoplanet hunter Plato in space-like conditions

The European Space Agency is developing a new exoplanet hunter mission named Plato, which will launch in 2026. Plato's ability to identify smaller planets in larger orbits than current telescopes is expected to lead to the discovery of Earth-sized planets within the habitable zone,...

New Jupiter-sized exoplanet discovered with TESS

Pennsylvania State University (PSU) astronomers detected a new Jupiter-sized extrasolar world. They have used NASA's Transiting Exoplanet Survey Satellite (TESS). The new found exoplanet is designated as TOI-3757 b. It is slightly larger than Jupiter but more than three times less massive than the...

Water vapor detected in new found exoplanet

TOI-674 b is a recently discovered planet. It is a bit bigger than Neptune and it orbits a red-dwarf star about 150 light-years away. It is an exoplanet. It has water vapor in its atmosphere. The question is how much water vapor its atmosphere...

Scientists iron out the interiors of exoplanets

Lawrence Livermore National Laboratory scientists have used lasers to determine the high-pressure melting curve and structural properties of pure iron up to 1,000 GPa. This is three times the pressure of Earth's inner core. It is also four times greater pressure than any previous...
