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.
The TESS mission announces eight confirmed planets along with hundreds of exoplanet candidates.
Infant worlds might gobble up dust quickly, the interstellar environment might feed protoplanetary disks, or planet-building dust could be hiding in plain sight. Although disks of gas and dust around young stars are a necessary precursor to planet formation, an expanded survey of stars in our Galaxy confirms earlier doubts…
