What can an extremely hot Neptune-sized exoplanet teach scientists about exoplanetary weather? This is what a recent study published Nature Astronomy hopes to address as an international team of ...

Officially named Cuancoá, this Neptune-sized exoplanet was discovered in 2020 and orbits its sun-like star every 19 hours. With a mass about 29 times that of Earth, LTT 9779 b lies within the ...

Illustration of LTT 9779 b, the only known ultra-hot Neptune. This planet orbits so close to its star that its atmosphere is scorching hot, glowing from its own heat while also reflecting starlight.

LTT 9779 b, nearly 30 times Earth's mass, is certainly extreme. It's tidally locked to its star — like the moon is locked to Earth — meaning that one side of it incessantly seared by its star ...

LTT 9779 b's reflective clouds and high metallicity may shed light on how atmospheres evolve in extreme environments, too. LTT 9779 b is a remarkable laboratory for exploring these questions, ...

Planet LTT 9779 b is being dubbed a "ultra-hot Neptune" because it is so unusually close. "It's a planet that shouldn't exist," study co-author Vivien Parmentier, ...

LTT 9779 b, an exoplanet 262 light years from Earth, always stares directly at the sun. With a surface of nearly 2000 degrees Celsius (about 3632 degrees Fahrenheit), the planet glows bright red while ...

A new extremely hot exoplanet, LTT 9779 b, the shiniest exoplanet ever discovered, is covered in metallic clouds. The exoplanet, which was first noticed by NASA’s Transiting Exoplanet Survey ...
