Universe’s backbone—a black hole?

To escape the Earth’s gravitational influence, you need to have a certain escape velocity (even if you are the Superman), you must fly up towards space with approx. 40,320 km/h, however, a speed of 42.1 km/s is required to escape the Sun’s gravity (and exit the Solar System) from the same position. But what if…

A meeting place – Atmosphere and Space

The atmosphere is just the gases surrounding Earth or any other planet in the form of layers. What keeps these layers intact is the gravity of a planet. When the planets were forming, the gases being released from volcanic activity and the interior of planets led to the formation of the atmosphere of the planets,…

Our Fast and Furious Universe

The title, as it says, is applicable to our Universe. The speeds that we are talking about here are faster than anything on Earth. Can anything on Earth move faster than Earth itself? The speed at which Earth rotates around its own axis is 1670 km/h (at the equator); the speed is slower at the…

Powerhouse of beauty and star formation-The Orion Nebula

Orion Nebula, also known as Messier 42, is a diffuse nebula situated in the Milky Way. A diffuse nebula is a cloud of interstellar material, widespread heaps of gas and dust. If they are massive enough, then they lead to the formation of stars. The Orion Nebula is the nearest “star factory” and is visible…

Importance of the Moon for Earth

The Moon was formed 4.5 billion years ago. It was formed when proto-Earth underwent a catastrophic collision with another planetoid similar in size to Mars, and the debris thus created started to accumulate around Earth. Eventually, the accretion of the debris led to its formation. If the Moon is destroyed in one way or another,…
