NASA's Dawn Spacecraft Discovers Salty Water Reservoir At 25 Mile Depth Of Ceres Dwarf Planet

The dwarf planet Ceres is a barren space rock which located in Kuiper belt. Kuiper belt is an asteroid belt which located between Jupiter and Mars. This dwarf planet Ceres total radius is about 940 km long and also it is the largest asteroid of Kuiper belt.

NASA's Dawn spacecraft have captured new high resolution images of Ceres from mars orbiter and this image captured from 35 km long of Ceres dwarf planet. After released this image US scientists and European scientists started to analyse this dwarf planet.Generally these images revealed that mysterious brighter region on Ceres.

Scientists have focused on the 20 million year old Occator crater. Occator crater is most brightest area on Ceres which total area is about 92 square km. By using infrared imaging system scientists have figured out that brightest area sodium carbonate rich region. Sodium carbonate is an organic compound which found at mass amount in sea water and it also highly reflective which determines that there is an ice reservoir beneath the Ceres's surface and may be this ice formed from ocean water.

The Ceres dwarf planet have also own gravitational force which is less than 3% of earth gravity. After many research scientist have started to study the gravity of Ceres and they confirmed that salt enriched water reservoir is located about 40 km deep form it's surface and this brine's area is about 100 square miles.

Scientists have discovered sodium carbonate on Ceres which made from the mixture of sodium, carbon and oxygen. These sodium, carbon and oxygen materials are most needed elements for life existing and developing. 

Dawn principal investigator Carol Raymond said that we have found two main hole where liquids come to the surface. This is the evidence of presence of liquid water beneath the Occator crater region but after water reach to the surface it quickly dehydrated and stay only salt rocks.
