A large number of space probes and robots are exploring mars in search of life. Water is the main requirement for the existence of life on any place. The key role of water in existence of life has caused the scientific explorations to look for water on Mars Planet. You may have heard earlier that the water was present in the form of oceans in the ancient Mars and in the form of ice on Continue reading “NASA Confirms the Evidence of Liquid Water on Mars Planet”

NASA Research Suggests Water on Mars Planet was more than Earth’s Arctic Ocean

NASA research suggest that a primitive ocean on Mars held more water than Earth’s Arctic ocean. A six year analysis of water on Mars planet suggests that the Red Planet has lost the equivalent of an ocean’s worth of water over the past four billion years. However a debate has started raising the question of wheather the planet Mars was hot enough to host such an ocean. Continue reading “NASA Research Suggests Water on Mars Planet was more than Earth’s Arctic Ocean”

How does Venus protect its atmosphere from solar wind in the absence of Magnetosphere?

The solar wind is composed of high energy charged particle which when interact with planetary atmosphere causes degradation to the atmosphere. The Magnetosphere of planet protects the atmosphere of the¬†planet from these solar winds by deflecting charged particles. For example, the planet Mars has no planetary magnetic field to protect its atmosphere from the solar wind which results in continuous loss of atmosphere to space. The planet Venus is much closer to the Sun Continue reading “How does Venus protect its atmosphere from solar wind in the absence of Magnetosphere?”
