  Since the beginning people on planet Earth were curious about knowing the hidden secrets of other planets on which they live and other planets of the solar system. Their common questions were what other planets are made of? Do they have water and an atmosphere? Can humans live there? So, I will try to give a comprehensive view of all planets of the solar system and answers to commonly asked questions.             Let’s discuss first what is a planet. Planets are celestial bodies that orbit around a star, such as our Sun. They are large enough to have a nearly spherical shape due to their own gravity. They are classified into 2 main types Terrestrial planets and gas giants. Terrestrial planets are small, rocky planets like Earth. They have solid surfaces and are composed of mostly silicate rocks and metals. Gas giants are large planets made up mostly of gases, such as hydrogen and helium, along with other volatile compounds. G...

       Since the beginning people on Earth were curious to understand the universe. What structures are present in our universe and their details? So in this article, I will try to mention the details of the most mysterious objects called Black holes. Firstly, Einstein in his theory of relativity predicted black holes, and first time in 2019 we captured the first image of a black hole named M-87. I will try my best to explain the concepts very simpler so that one can easily understand it. Let’s start with what is black hole A black hole is a region in space where gravity is so strong that nothing, not even light, can escape its gravitational pull. It is formed when a massive star collapses under its own gravity during a supernova explosion. The collapse causes the star's matter to become extremely dense, creating a gravitational field that is incredibly intense. Now let’s discuss briefly how black holes are actually formed. When a star that is more massive than th...
