The latest observations show that Ceres might face a few highlights mysterious jet of steam plume into space, suggests the dwarf planet’s geological activity has very active.
New observations to the mysterious highlights Ceres surface material is likely to be combined with ice water vapor plume.
According to foreign media reports, the latest observations show that Ceres may face a few highlights mysterious jet of steam plume into space, suggests the dwarf planet’s geological activity has very active.
NASA’s Dawn spacecraft near Ceres shooting some images, the scientists at the Lunar and Planetary Science meeting that discussed the latest captured image is displayed Ceres highlights may be water ice, will be announced lurking beneath the surface of the planet substance provide important clues .
Max Planck Institute for Solar System Research, Germany Andreas Larson Adams (Andreas Nathues) Dr. said: “This plume among Ceres changing day, during the day, the plume becomes brighter, In the dusk, the plume becomes dark, into the evening, the plume completely disappeared. ”
Initially mysterious highlights Hubble images found again in the near future spacecraft Dawn filming, although scientists speculate these highlights include highly reflective ice substances, but Dawn spacecraft has not been fully observed at close range, the latest data show These bright spots are likely to be ice water.
Currently the brightest highlights scientist called “5 features” from different times during the day and angle shooting photos show will most likely related to the plume material, the area is located at the bottom of a 80 km diameter crater. Larson Adams said: “We think this is some kind of highlights outgassing phenomenon, we need high-resolution image data to confirm.”
Not everyone accepts the initial plume quickly explained University of Washington, Bill McKinnon (Bill McKinnon) said you never saw the plume has highlights, frost and snow in Ceres surface, but we need further observation.
Ceres larger, outer shape is round, rich in a lot of water, is a strange celestial bodies in the asteroid belt, Ceres scientists have speculated the existence of sub-surface layer of the ocean or frozen water, as a dwarf planet, it is more like a planet or ice satellite, instead of before, astronomers understand asteroids.
