This image depicts a hot Jupiter's crescent, being illuminated by a host star located off-screen to the bottom left. The dayside, being overexposed, is pure white, and the atmosphere shows up as a white glow surrounding the dayside. The nightside is dull pinkish, with cooler clouds showing up as darker regions. The two large hemispherical storms appear on the image as well.

A study on drawing a hot Jupiter's nightside.

The dayside is overexposed. The nightside is pinkish from the combination of blackbody radiation and absorption from Na/K/H2O, similar to brown dwarfs.

30 Years After 51 Pegasi b: How the First Exoplanet Changed Astronomy

On Oct. 6 1995 astronomers Michel Mayor and Didier Queloz announced 51 Pegasi b, a hot-Jupiter with a four-day orbit and surface temperatures near 1,830°F. getnews.me/30-years-after-51-pegasi... #exoplanets #hotjupiter #51pegasib

Artist's impression of the exoplanet HD 209458b, a "hot Jupiter" orbiting very close to its star. Its atmosphere is evaporating, and recent observations suggest the presence of water vapor, potentially indicating the possibility of life beyond our solar system.

This #exoplanet transit was recorded by my Unistellar #eVscope last night. The #HotJupiter class planet is a bit larger and lighter than its namesake and resides in a binary star system, where it orbits the sun-like main star in just 2.9 days.
