The Universe’s Darkest Secrets Revealed!

[00:00:00]Did you know scientists [music] discovered planets with weather more extreme than anything on Earth? On some worlds, temperatures become so intense [music] that metals can vaporize into the atmosphere and fall back as rain.

[00:00:11]You might not realize how powerful stars truly are, but some stars release so much energy that they temporarily outshine billions of other stars combined. Did you know scientists believe most of the universe is invisible? Massive unseen structures may stretch across space holding entire galaxies together. You might think every orbits a star, but scientists discovered rogue planets drifting alone through space completely isolated in endless darkness. Did you know black holes are so powerful that they can bend light and warp space itself? Near them, the normal rules of reality begin to break down.

[00:00:49]You might not believe this, but water exists throughout the universe.
