What We See in the Oldest Light: Exploring the Cosmic Microwave Background
If we look as far out as possible, we would see a uniform glow of low level radiation in all directions. This is called the cosmic microwave background, or CMB. It is the oldest light in the universe. And it...

3 Biggest James Webb Space Telescope Discoveries
James Webb captures infrared light, which allows us to see billions of light years away. Some galaxies would not be visible otherwise, because their light has redshifted beyond visible light spectrum due to the...

How the First Molecules Formed in the Universe
SUMMARY:
To make most complex structures in the universe like trees, and us, you need more than atoms. You need molecules. How do you go from atoms formed in the core of stars, to molecules that can lead to living...

Five Science "Facts" that Are Widely Believed but Wrong
SUMMARY
"Facts" that are not quite correct: 1) There is no gravity in space 2) Nothing can go faster than the speed of light. 3) Bees shouldn’t be able to fly according to physics. I will explain this using Physics 4)...
