Warm Neptune-size exoplanets are not nearly as common as super-Earths or hot Jupiters — and we are now closer to finding out why. Our galaxy apparently has a dearth of Neptune-size worlds that orbit ...
A Neptune-sized planet closely orbiting its host star has just been discovered, making it only the fourth object of its kind ever identified. Scientists detected the planet, designated TOI-3261 b, ...
The James Webb Space Telescope has detected water vapor and thick clouds on LTT 9779 b, an ultra-hot Neptune locked in a blistering 19-hour orbit. When you purchase through links on our site, we may ...
A strange puzzle has been taxing astronomers for many years: where are the hot Neptunes? For unknown reasons, there is an notable absence of planets the size of Neptune which lie close to their ...
A team of astronomers has used data gathered from TESS and the Spitzer space telescope to investigate the atmosphere of a distant planet known as LTT 9779b. The planet is described as a "hot Neptune," ...
According to simulations and models, exoplanet sizes should be spread out relatively evenly. But with the exoplanet tally approaching 4,000, that hasn't really been the case. A type of world dubbed a ...
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 ...
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 ...
