Everybody is usually familiar with word ‘Magnet’, magnet is a small piece of rock or metal that can attract many types of metals like iron, cobalt, and nickel. The range of application of magnet is also very wide from compass to electronic devices. The magnet creates some effects in the surrounding space that can affect other magnets and metal, this effect is called magnetic field. Magnet interacts with other material through this magnetic field. Continue reading “Magnetic Home sustaining life”

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?”

‘Life’ is one of the most mysterious words. The planet Earth is the only known place where life exists. Astronomers are too keen to know about the existence of life on other places than Earth. Lots of new techniques and experiments are done daily to observe the evidence of life outside the planet Earth. Let us look at some basic requirements for the existence of life on any planet or moon.
