Astrophysicists discover that ultrahot planets have starlike atmospheres

Scattered throughout the cosmos, astronomers are uncovering a strange new class of exoplanets too small to be stars, but too big to be planets. They're called ultra-hot Jupiters. These incredibly hot gas giants sit much closer to their host stars than Mercury does to the sun, which causes tidal locking. That means the same side of the planet always faces its star. Dayside temperatures can exceed 3,500 degrees Fahrenheit (1,900 Celsius). Nightside temperatures hover around 1,800 F (1,000 C
