ceres planet

Ceres is a relatively small object in the solar system, as the smallest and the closest dwarf planet to Earth, Nola Taylor Redd wrote for Space in 2018. This conclusion depended on scientists making a key discovery: salt compounds — sodium chloride chemically bound with water and ammonium chloride — concentrated in Cerealia Facula.On Ceres’ surface, salts bearing water quickly dehydrate. This is evidence both for the presence of liquid below the region of Occator and for the ongoing transfer of material from the deep interior to the surface.Some of the evidence for recent liquids in Occator comes from the bright deposits, but other clues come from an assortment of unusual conical hills. PASADENA, Calif. - The dwarf planet Ceres was long believed to be a barren rock, but new images from NASA’s Dawn mission proves otherwise. Results from NASA's second extended Dawn mission have … These deposits appear to have erupted within the last 2 million years, far too recent to have come from the melt generated by the initial impact.The brines may still be percolating up to the surface today.This false-color mosaic image highlights the recently exposed brine, or salty liquids (red), that were pushed up from a deep reservoir under Ceres’ crust. “The impact heat subsided after a few million years. Ceres is the largest object in the asteroid belt and the only dwarf planet in the inner solar system. However, it is possible to characterize the total mass deficiency created by the low-density reservoir.“This paper provides the first coherent story for the connection between the surface evaporates and the deep brine for the region of Occator and leaves the question about whether the brine layer is global open to future investigation,” he said.The research not only confirmed that the bright regions are young — some less than 2 million years old — but also found that the geologic activity driving these deposits could be ongoing. Scientists are attributing the mysterious bright spots on Ceres, the largest object in the main asteroid belt, to a gigantic reservoir of salty water beneath the dwarf planet’s crust.
The largest object in the asteroid belt, a dwarf planet named Ceres, might contain reservoirs of briny liquid, Michael Greshko reports for “We’ve provided strong evidence that Ceres is geologically active in the present, [or] at least in the very recent past,” Dawn’s lead investigatorCeres is a relatively small object in the solar system, as the smallest and the closest dwarf planet to Earth, Nola Taylor Redd wrote for Much of the new research focuses on Occator crater, Meghan Bartels reports for Some of the patches seem to be pools that followed the impact that made the crater and melted Ceres’ icy material. It is the only dwarf planet located in the inner solar system.

Her work has also appeared in National Geographic and SciShow.

The researchers calculated that after the ice reaches Ceres’ surface, the water inside should disappear within a century, leaving behind salt crystals that would be undetectable by Dawn’s instruments. And now we know it may be an ocean … Post was not sent - check your email addresses! However, the scientists recognized that the impact could have fractured rock deep enough to reach the reservoir inferred from the observed low gravity. A crater named Occator is to the left of the blue area This composite image shows gravity anomalies (red is high, blue is low) on the right side and Ceres’ real colors on the left. Measurements of Dawn’s velocity as it passed over the Occator crater also suggest that there is lower-density material underneath the surface, which could be liquid.NASA planetary scientist Lindy Elkins-Tanton, who wasn’t involved with the Ceres studies, tells The liquid in Ceres’ reservoirs would be more like mud than water as we know it. But Dawn’s measurements show they still have water, so the fluids must have reached the surface very recently. Such combined analysis led to the most likely scenario that the low-density region could be a reservoir of briny water.The team proposed that initially, the impact melted ice underground in a small reservoir that mostly froze again within a few million years.

Ceres was the first object discovered in the main asteroid belt, a vast region containing planet building blocks encircling the Sun — leftovers from the formation of the Solar System — between the orbits of Mars and Jupiter.

Because Dawn detected the presence of hydrohalite, the researchers say that brine from inside of Ceres must still be bubbling up to the surface.“I remain pretty skeptical about a subsurface ocean on Ceres,” geologist There may be a chance for NASA to gather that evidence. A team led by planetary scientist Julie Castillo-Rogez, who co-authored some of the new research, is proposing a sample-return mission from Ceres, reports Theresa Machemer is a freelance writer based in Washington DC.

The bright spots are near the center of Occator. It’s full of salts and other fine minerals that help keep it from freezing, the same way that salt prevents ice slicks from forming on roads, according to But with enough heat from impacts, the dwarf planet may have once been habitable, although it may not have actually been inhabited.“We’ve got this recent, warm, wet geologic system that has all the ingredients that we think you need for life,” Johns Hopkins University planetary geologist Kirby Runyon, who wasn’t involved with the research, tells Some of the ice that the team spotted on Ceres’ surface, called hydrohalite, is made of sodium chloride—table salt—crystals with water molecules trapped inside. Ceres is the only dwarf planet in the inner solar system.

While ice on the icy moons in the outer Solar System — Saturn’s Enceladus and Jupiter’s Europa, for example — is warmed and melted by gravitational tidal interactions with the planets, it now seems likely that dwarf planets and asteroids may also preserve reservoirs of liquid water, despite the fact that they do not benefit from the same tidal heating.And as NASA often states, to find life on other planets, follow the water.The findings are presented in a special collection of papers published today (Aug. 10) in the journals Ceres was the first object discovered in the main asteroid belt, a vast region containing planet building blocks encircling the Sun — leftovers from the formation of the Solar System — between the orbits of Mars and Jupiter.
