List of heavenly bodies in solar system7/30/2023 ![]() ![]() Still, it speaks to the abundance in our solar system, and the ways our views have changed from a dry solar system with a pale blue dot in its midst to one of abundant water and rife with possibilities for life. And water is also embedded in Saturn’s dazzling rings. Trace amounts of water vapor have been detected on Venus’, Jupiter’s, and Saturn’s atmospheres. There are hundreds more places in the solar system where water can be found, whether tiny, ice-packed moonlets never given official mythological names or just areas with a moderate accumulation of ice. Trace amounts of water vapor have been detected here. The Mariner 10 spacecraft captured this view of Venus’ clouds, enhanced. The other chief possibility is that Mimas has a football-shaped core giving it the unusual tilt.Īt around the size of Enceladus, the moon is too small to retain the heat from its formation, so any ocean on Mimas would have to have an outside force acting on it-possibly radioactive decay. The Cassini team says that it could be an ocean. The moon wobbles as it orbits Saturn, which indicates something unusual going on beneath the surface. Yet a few unusual features hint at something weird on Mimas. ![]() There doesn’t seem to be much more to it than water ice. ![]() Mimas, the “Death Star moon,” is pretty much one big snowball. NASA/JPL-Caltech/Space Science Institute/Lunar and Planetary Institute The colors shown are enhanced, or broader, relative to human vision, extending into the ultraviolet and infrared range. This photo of Saturn’s moon Mimas was created using a color mosaic produced from images taken by NASA’s Cassini spacecraft during its first ten years exploring the Saturn system. NASA’s Europa Clipper will reach this ocean moon in 2030 to conduct a long awaited investigation. Europa could provide the possibility not just for life, but, if the conditions were just right, even complex life. There has been some evidence of ice geysers shooting from the surface of Europa, as well as evidence that the ocean could have Hadley cells-warm water radiating from the moon’s equator. Thanks to the tidal effects from Jupiter (friction inside the moon created by the pull of the planet’s gravity), the water would be kept liquid and possibly even warm below the icy crust, helped by possible hydrothermal vents. NASA/JPL-Caltech/SETI InstituteĮuropa has been the biggest contender for life for years now, with a craggy, icy crust hinting in almost every way at an ocean below. Beyond Earth, Europa is considered one of the most promising currently habitable environments in our solar system. NASA targets some of these bodies with spacecraft loaded with instrumentation that help tease out the secrets lurking in these icy bodies.Jupiter’s moon Europa shows strong evidence for an ocean of liquid water beneath its icy crust. Recent spacecraft encounters with comets seem to raise more questions then they answer and some finds are quite unexpected. Short period comets are thought to come from the Kuiper Belt on the outskirts of Neptune’s orbit and further, and longer period comets are thought to come from the Oort cloud, a vast spherical shell that surrounds the solar system at a huge distance. Comets can sprout tails extending many tens of millions of miles, during their closest approach to the sun. ![]() They travel around the sun in elliptical orbits and can be inclined to the plane of the solar system at any angle. This region beyond Neptune is also the most probable birthplace of the short-period comets.Ĭomets are pristine remnants from the formation of the solar system that are comprised of minerals, rock and mostly ice, much like a dirty snowball. The Kuiper Belt is a region extending from Neptune’s orbit out to the far and distant reaches of the solar system and possibly holds the best available record of the original interstellar materials that formed the solar nebula. The Oort Cloud is a spherical shell of millions of icy bodies which surrounds the solar system at vast distances and is thought to be the birth place of long-period comets. This spectacular image of comet Tempel 1 was taken 67 seconds after it obliterated Deep Impact's impactor spacecraft. ![]()
