Comet 67P

Even though scientists already knew about the existence of ice on Comet 67P/Churyumov-Gerasimenko — the same comet that the Rosetta space probe has been tailing and observing since 2014 — scientists have finally confirmed there is frozen H20 right beneath the celestial object's surface.

Using data sets sent from the Rosetta's Visible and Infrared Thermal Imaging Spectrometer (VIRTIS), which is more or less an infrared detector, a team of scientists based at the National Institute for Astrophysics in Rome was able to determine the presence of grain-sized speckles of water ice on areas of 67P where bits of the comet's outer crust had broken off, leaving the frozen droplets exposed.

While the researchers, who published their results in the scientific journal Nature, determined that "the nucleus can develop an extended and complex coating in which the outer dehydrated crust is superimposed on layers enriched in water ice," it is still unclear as to how the ice actually formed there in the first place.
