The case of the missing Jupiters: Gas giant planets are a no-show around small red stars

Astronomers have revealed that the smallest and most common kinds of stars in the universe, called red dwarfs, very rarely host big, Jupiter-like planets. This absence of Jupiter analogs could have major impacts on the development ...

NIRISS instrument on Webb maps an ultra-hot Jupiter-like exoplanet's atmosphere

400 light-years out there is something that is so tantalizing that astronomers have been studying it since its discovery in 2009. One orbit for WASP-18 b around its star that is slightly larger than our sun takes just 23 ...

One-third of galaxy's most common planets could be in habitable zone

Our familiar, warm, yellow sun is a relative rarity in the Milky Way. By far the most common stars are considerably smaller and cooler, sporting just half the mass of our sun at most. Billions of planets orbit these common ...

One in ten stars ate a Jupiter-sized planet, suggests paper

In space, cataclysmic events happen to stars all the time. Some explode as supernovae, some get torn apart by black holes, and some suffer other fates. But when it comes to planets, stars turn the tables. Then it's the stars ...
