Cornell astronomers have improved a model to gauge the temperatures of exoplanets
Atmospheric gases recede from a “hot Jupiter,” which is a Jupiter-size, egg-shaped planet that orbits close to its own sun, in this artistic rendering. Cornell astronomers have developed a new mathematical model for determining temperatures on different parts of...

Yale’s EXPRES looks to the skies of a scorching, distant planet
The planet MASCARA-2 b, a Jupiter-like gas giant roughly 2.68 quadrillion miles from Earth. CREDIT: Sam Cabot. Take a look at the planet Kelt 20-b, a hot Jupiter located 450 ly away and orbiting a hot A type star. This world orbits every 3.5 days at a distance just 5%...
New results from ALPINE reveal what appear to be spiral galaxies in the infant universe
