Astronomers report the discovery of a new warm Jupiter exoplanet orbiting a distant star in the open cluster Messier 67. The newfound extrasolar world, designated S1429 b, is almost twice as massive as Jupiter. The finding ...
Astronomers from the Harvard–Smithsonian Center for Astrophysics (CfA) and elsewhere, report the discovery of a new 'warm Jupiter' exoplanet orbiting a rapidly rotating F-type star. The newfound alien world, designated ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered two new "hot Jupiter" exoplanets. The newfound alien worlds, designated TOI-4377 b and TOI-4551 b, both orbit ...
Using NASA's Kepler and ESA's Gaia spacecraft, an international team of astronomers has conducted an astroseismic investigation of six giant stars in the open cluster NGC 6866. The study, presented August 24 on the pre-print ...
When our sun reaches the end of its life, it will expand to 100 times its current size, enveloping the Earth. Many planets in other solar systems face a similar doom as their host stars grow old. But not all hope is lost, ...
