Without a spacesuit, there is no chance of surviving in the scary cosmic void. In science fiction movies, we often see people’s heads exploding or being frozen by the apparent pressure differential or lack of heat, respectively. As long...

From the ancient beliefs of Earth being the center of the solar system to the discovery of other planets orbiting the Sun, we delve into the history and classification of these celestial bodies. A planet is an astronomical or celestial...

This is a story about how humans in 1054 AD witnessed the supernova that created the crab nebula.

Learn the basics about Atomic Mass Units. The atomic mass is used to find the average mass of elements and molecules and to solve stoichiometry problems. Find out more in this video!

Helium is so great...and we are running out of it, but also we are not running out of it.

The video explains two processes involving atomic nuclei that release large amounts of energy - nuclear fission and nuclear fusion. The video explains how uranium 235 can be made to undergo nuclear fission and also discusses the concept...

The video explains the fundamental concepts of mass number, atomic number, and isotopes. It begins by presenting a diagram of an atom and the three particles contained within it - neutrons, protons, and electrons - and their charges. The...
