Great documentaries about astronomy :exoplanets, supernova, galaxies, superstars, massive black holes, etc
You know, stars and all stuff…

Black Holes: Universe Mysteries

A black hole is a region of space-time where gravity prevents anything, including light, from escaping.

Nothing can escape, not even lights.

Black holes are the most destructive thing and a doorway to the biggest mysteries in the universe. It’s hard to study something that by nature evades detection and shouldn’t even exist!

So here’s a great documentary about black holes.

Size of the Stars: Giant, Supergiant, Hypergiant!

In the observable Universe, 75% of the stars are smaller and less massive than the Sun.
Most of the others are similar in size and mass to the Sun, or maybe a little larger.

Nope. You are not the center of the universe!


But there are some very rare stars out there that are much larger and more massive than our Sun; these are the giant stars, supergiant stars and more rare: hypergiant stars!

Here we go!

Darwin IV Alien Planet and Extraterrestrial life !

Darwin IV is a fictional planet that was the subject of Wayne Barlowe’s book Expedition and the television special, Alien Planet, based on Expedition.

To infinity and beyond !

The Fourth planet in the darwin system Darwin IV is (in fiction) the only planet known to support life. Darwin IV is somewhat darker in the daytime because its star is higher. It is also one of the only planets in the system to be in the habitable zone. In this documentary you learn that liquid water is the most precious element in the whole universe.

Darwin IV Facts (At time of departure)

• Gravity: 0.6 Earth
• Solar energy at top of atmosphere: 79% that of Earth
• Atmospheric density: 200% that of Earth (est.)
• Microscopic life present: Some indication
• Macroscopic life present: Unknown

Darwin IV was once a planet much like earth and did have oceans. But Darwin’s oceans evaporated millions of years ago leaving nothing but a small blue sea and the ice caps, lakes, ponds and rivers that remained on the planet. Continents became large mountains while the ocean floor became savanna and deserts.

The documentary: last 1H33. Lien Youtube.

Want to leave Earth ? It’s possible now !

Space Travel has always been a dream. Explore and live in other world too.

At least…From now!

Mars One is a private company that aims to land humans on Mars to live there, forever!

If you have too much enemies on Earth, you might be interested…

The plan is to send a communications satellite to the planet by 2016 and after several stages, finally land humans on Mars for permanent settlement in 2023.

Yes, it would be a one way trip! (for the best and the worst)

Pros: You will experiment an unique travel in the whole history, become the first martians colon, leave your name to the posterity.
You will experiment an alien lifestyle and travel in space.

Cons: You may hate life on Mars and/or your new mates.
Miss your friends, family and Earth’s lifestyle.
No Internet on Mars.

The Mars-one Base project

If you have always wanted to live like Star Wars, this maybe the time to move on!

The first 40 astronauts will be selected and will live in a replica of the settlement built for training purposes in 2013!
