The geyser on Enceladus.
The small moon is spewing water directly into space. This cryovolcanism is likely responsible for Saturn's icy E-ring. Encelandus has the highest albedo of any body in the solar system because it is composed mainly of ice. Scientists are excited about the prospect of life of Enceladus because it possesses liquid water, an atmosphere, and tectonism.
It's recently become a hot topic in the news. But alas, it is not new news.
Still, it's extremely interesting.
