Hubble Reveals Origins of Hippocamp — The Tiny Moon of Neptune that Shouldn’t Be There

Hippocamp is one of the smallest, and darkest, moons of Neptune. Known to astronomers as “The Moon that Shouldn’t be There,” it orbits the giant planet at a distance so close to the larger moon of Proteus that it should have already been destroyed. Researchers using the Hubble Space Telescope have now concluded that this tiny satellite, just 20 miles in diameter, broke off of its larger neighbor billions of years ago, following an impact with a comet. When Voyager 2 visited Neptune in 1989, it photographed a massive impact crater on Proteus, which is likely evidence of this ancient collision.

NASA Readies Europa Clipper for First In-Depth Study of Jupiter’s Water Moon Europa

NASA is readying a new spacecraft, the Europa Clipper, for a journey to explore the giant water moon of Jupiter. Europa is believed to have oceans of liquid water deeper than any found on Earth, which are heated by bending and flexing as it orbits its massive companion. The spacecraft, due for launch in 2023, will carry instruments to measure the composition and condition of the oceans of Europa, as well as that world’s atmosphere, surface, and magnetic field. Astronomers believe that Europs may be one of the most likely places in the solar system to find alien life,

Rain on Saturn’s Moon Titan Could Make this World the Life of the Party

Evidence of rain has been spotted near the north pole of Titan, the largest moon of Saturn, for the first time ever, Since the arrival of the Cassini spacecraft at Saturn in 2004, astronomers have been expecting to see this phenomenon, which they expected to occur in 2016 or 2017. Titan is the second-largest moon in the Solar System, and is the only one known to possess a thick atmosphere, along with vast lakes and seas of liquid methane and ethane. These conditions make it one of the most-likely places to find life in our solar system. Currently, NASA is considering sending a drone, called Dragonfly, to the moon, to be launched in the year 2025.
