A spacecraft mission to Saturn’s moon Enceladus found unexpectedly high methane in its ice plumes, fueling speculation about life in its hidden ocean. A new Nature Astronomy sutdy shows current models can’t reliably distinguish that methane from purely non-biological sources. The one signal that could tell life apart from chemistry, a molecular “handedness” pattern, would likely be destroyed before we could ever detect it.
You’re probably used to seeing tabloids in the checkout aisle of the grocery store claiming all sorts of wild things. 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.

For today’s bite guest author, Savaria Parrish, explores the prospects for habitability on planets around a class of stellar remnants known as white dwarfs!
Today we interview UCLA planetary scientist David Jewitt, who helped discover the Kuiper Belt and is now studying some of the Solar System’s strangest visitors!
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.
