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.
Observations of the youngest confirmed planet, CI Tau b, suggest it's still hot from its birth — a point in favor of a quick-start model of formation.
Two teams of astronomers have announced the discovery of a Neptune-size planet in an unexpected orbit and three exocomets whizzing around nearby star Beta Pictoris.
Astronomers have found a third planet circling a pair of stars in the Kepler 47 system.
New studies are challenging the core accretion theory, the primary model astronomers use to understand how worlds form in our solar system and beyond.
