WASP-76

WASP-76

system

WASP-76 — a hot F-type star ~634 light-years away in Pisces, host to WASP-76 b, where it RAINS IRON. Its dayside is so hot (~2,400°C) that iron vaporises; winds carry the iron vapour to the cooler nightside, where models indicate it condenses and falls as molten iron rain. Descend to explore this bloated, blistering world.

How we know

Note
A real star system, shown at its measured position in the galaxy. Its star and confirmed planets — their measured sizes and how each was found — are on the cards inside; descend to explore them. Distances follow Gaia parallax; planet data follow the NASA Exoplanet Archive.

Discovery & history

Name
A designation from the Wide Angle Search for Planets (WASP) survey.

Discovered transiting in 2016, WASP-76 b is a puffed-up ultra-hot Jupiter. In 2020 the ESPRESSO spectrograph detected iron vapour on the hot dayside disappearing at the nightside edge — the signature of iron condensing and raining out, one of the most vivid pictures of alien weather yet obtained.
