Mercury is the planet closest to the sun and it is also the planet to receive maximum temperature from the Sun making the existence of water surprising and what’s more surprising is that NASA’s recent images show the existence of water ice on Mercury.

The surface temperatures in Mercury is a minimum of 430 degreeds every day and a Mercury day is calculated as 58 Earth days. This planet, a permanent oven, has craters on the poles that are shadowed from the sun and these poles give the shade and coolness required to retain water.

Scientists have been thinking since the mid 1990s when images of mercury were obtained, that there may actually be ice on this planet and their theory has now been proved true and the radio telescopes scanning the planet have found areas where the radar signals are strongly reflected that shows there is presence of ice and the images that NASA managed to take are optical proof that the planet has ice.

Following this, scientists have examined the presence of impact craters around the north pole of the planet and the largest crater Prokofiev which is roughly 70 miles wide has been found to be holding boundaries of ice and the crater itself has sharp edges and they sharp edges still remain sharp and ice has not melted over time and become smooth.

The study’s authors wrote that the sharp boundaries indicate that the volatile deposits at the planet are geologically young and they are restored at the surface or they are delivered to the planet very recently. If the latter is true, it shows that there exists an unidentified way in the solar system to deliver water other than the known methods. It also shows that there might be changes in our moon and it is generally believed that the moon has areas of water and ice.
