Dwarf Planet Ceres in an Ocean world - Nasa finds salty water under the surface

Recently a study published which tells us about a dwarf planet which lies between asteroid belt of Mars and Jupiter that there must have been a ocean of water that there Dawn spacecraft captures high resolution pictures of its surface. 

The Dwarf planet Ceres long believed to be a barren space rock is an ocean world with reservoirs of sea waters beneath its surface , the results of a major exploration mission .

First we will be discuss what are the condition of a Dwarf planet that make it different from other planet.

What is a Dwarf Planet ?

The International Astronomical Union defines a planet as being in orbit around the sun, has enough gravity to pull its mass into a rounded shape , and has cleared its orbit of other, smaller objects. This last criterion is the point at which planets and dwarf planets differ. A planet's gravity either attracts or pushes away the smaller bodies that would otherwise intersect its orbit; the gravity of a dwarf planet is not sufficient to make this happen.

Now you can here see that there are top big dwarf planet in our system and ceres discovered in 1801. Now a team of scientist from the United States and Europe have analysed images relayed from the orbiter , captured around 35 kilometers from the asteroid. They focused on the 20 million year old Occator crater and determined that here is an extensive reservoir of brine beneath its surface.

Several Studies published on Monday in the journals Nature Astronomy , Nature Geo-science and Nature Communications also shed further light on the dwarf planet which was discovered by Italian polymath Giuseppe Piazzi in 1801 as i told above.

Using infrared imaging one team discovered the presence of the compound hydrohalite a material common in sea ice but which until now had never been observed off of Earth - which was clear sign that Ceres used to have a sea in past which is now vanished and left its traces it means there is only sign left not a ocean of full water is present that time. Now it is clear that Ceres is a sort of ocean world as are some of Saturn's and Jupiters moons.

The material found on Ceres is extremely important in terms of astrobiology - team said." We know that these minerals are all essential for the emergence of life".That material is unstable on Ceres surface and hence must have been emplaced very recently. In a separate paper, US based researchers analyzed images of Occator crater and found that its mounds and hills have formed when water ejected by the impact of a meteor frozen on the surface.

Finding showed that such water freezing processed extent beyond Earth and Mars and have been active on Ceres in the geologically recent past.  

We are actually discoveries of Universe and only 10 percent of Universe we are able to study and rest is dark matter which we don't about it. As we know that there are millions of Galaxies and trillions of planet so possibility of Life is infinite and we are still don't know complete about our own Solar System so daily we are discovering something new our Universe.
