The scandals of life on Earth are abundant, and it seems like the rest of the solar system isn’t any different. Although you might not see their pictures on the front covers of any gossip magazines, Uranus and Neptune may not be what you think. Allegedly, these “ice giant” planets have a piping-hot secret that the authors of today’s paper are exposing.

There’s a puzzling gap in the distribution of exoplanet sizes. Today’s paper explores the role of photoevaporation and core composition on the formation of the radius valley.
How Far Can We See? The Limits of Planet Hunting
There’s a hard physical limit on spotting a planet next to its blinding star. However, it turns out today’s telescopes aren’t hitting it. New work maps out exactly how close in we could still detect the faint, Earth-like worlds we want to find the most.
