New observations by the James Webb Space Telescope suggest that an icy moon around Uranus may have an underground liquid ocean. Ariel is one of 27 moons around Uranus, the seventh planet from the sun and the third largest planet in the solar system. It’s one of four moons that scientists have long been interested in as part of a search for water across the solar system, the others being Umbriel, Titania and Oberon.

The object that smashed into Earth and kick-started the extinction that wiped out almost all dinosaurs 66 million years ago was an asteroid that originally formed beyond the orbit of Jupiter, according to geochemical evidence from the impact site in Chicxulub, Mexico. The findings, published on 15 August in Science, suggest that the mass extinction was the result of a train of events that began during the birth of the Solar System. Scientists had long suspected that the Chicxulub impactor, as it is known, was an asteroid from the outer Solar System, and these observations bolster the case.
