Among the wealth of exoplanets we’ve discovered beyond our solar system, some are temperate, some less so. New observations have now revealed what may be a particularly inhospitable environment: a planet literally disintegrating as it orbits its host.
Large observatories will require precise timing info to measure as many exoplanet atmospheres as possible. Backyard astronomers have the power to keep that intel fresh.
Astronomers have calculated the loss of planets around stars in globular clusters, and New Horizons returns observations of worlds in the outer solar system.
Astronomers have announced the discovery of Proxima Centauri c, an inhospitable super-Earth just 4.3 light-years away.
NASA's TESS mission announces the results from its first year of exoplanet-hunting in the southern sky, introducing us to some of our planetary neighbors.
A team of astronomers propose screening exoplanets by their temperatures to determine whether they host an atmosphere — and are worth following up.
Follow-up observations of an amateur-discovered exoplanet show that the planet orbits its star at the snow line, where ice giants may form.
Two independent teams of astronomers have discovered the signature of water vapor in the atmosphere of super-Earth K2-18b.
A mere 3 million years from now — a cosmic eye-blink away — the star WASP 12 might consume its exoplanet WASP-12b.
Astronomers announce another planet around Beta Pictoris, simulations explain Jupiter's large and fuzzy core, and observations reveal an ancient star.
