A team led by an astronomer from the University of Kansas has crunched data from NASA’s TESS and Spitzer space telescopes to portray for the first time the atmosphere of a highly unusual kind of ...

New NASA Hubble Space Telescope images of the distant planet Neptune show a dynamic atmosphere and capture the fleeting orbits of its satellites. The images have been assembled into a time-lapse movie ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new ...

But Webb's observations didn't just provide new pretty pictures of the ice giant planet's greenish-blue splotches. It revealed how odd Neptune's auroras are compared to other planets', glowing over ...

There aren't a lot of Hot Neptunes in the galaxy, and it's not entirely clear why. A Hot Neptune is, as the name implies, a Neptune-sized planet orbiting within 1 AU of its host star. While we've ...

Of all the potential super-Earths—terrestrial exoplanets more massive than Earth—out there, an exoplanet orbiting a star only 40 light-years away from us in the constellation Cetus might be the most ...
