Nebulae: Crash Course Astronomy #36

Nebulae: Crash Course Astronomy #36 Astronomers study a lot of gorgeous things, but nebulae might be the most breathtakingly beautiful of them all. Nebulae are clouds of gas and dust in space. They can glow on their own or reflect light from nearby stars. When they glow it’s usually predominantly red from hydrogen and green from oxygen, and when they reflect and scatter light it’s from massive hot stars, so they look blue. Stars are born in some nebulae, and create new ones as they die. Some nebulae are small and dense, others can be dozens or hundreds of light years across.

Formation of the Solar System Documentary – The Inner Secrets of Planets and Star

Formation of the Solar System Documentary - The Inner Secrets of Planets and Star In the beginning - before the 1920s, these words had no place in our scientific understanding of the universe. Astronomers believed the cosmos to be eternal and unchanging. We knew of only one galaxy and a few million visible stars, and this was the scope of our observable universe. Then astronomer Edwin Hubble observed, courtesy of redshift, distant galaxies speeding away from each other and formulated Hubble's Law to explain the universe's uniform expansion. Redshift just refers to a distant celestial body's shift toward longer, or redder, wavelengths, compliments of the Doppler effect.

The Search for Life in the Universe Documentary – Voyage To The Planets And Beyond The Solar System

The Search for Life in the Universe Documentary - Voyage To The Planets And Beyond The Solar System How do we find other planets? For life in the universe to be abundant, planets must be abundant. But planets are hard to detect because they are small, and much fainter than the stars they orbit. How does life begin? Scientists do not yet know how the first living things arose on Earth. The geological record shows that life appeared on Earth almost as soon as the young planet was cool and stable enough for living things to survive. This suggests that life may exist wherever conditions allow it.
