Astronomers have made detailed observations of a very exciting exoplanet, detecting a rugged surface temperature in the region of 200,200 degrees Celsius (792 ફેર degrees Fahrenheit). That temperature – measured by the European Space Agency’s characteristic exoplanet satellite (or CHOPS) – is enough to melt all rocks and metals, and …

Finding a potentially habitable exoplanet is not as easy as you might think. Orbiting at a warm distance from the host star is only the first step. Size and composition also play a role, as does the level of flare activity in the star. And all of that doesn’t mean …

Measurements from NASA’s Transit Exoplanet Study Satellite (TESS) have enabled astronomers to greatly improve their understanding of the strange environment of KELT-9b, one of the hottest known planets. “The rarity factor is high with KELT-9b,” said John Ahlers, an astronomer at the Universities Space Research Association in Columbia, Maryland, and …
