Animation of a flight into a dense cloud of dust within a bright emission nebula. Emission nebulae glow pink due to ionisation of the hydrogen gas they contain by the radiation from hot young stars recently born within them. The densest regions of ga...

Stages in the history of the Universe after the Big Bang. At 300,000 years, matter and radiation decouple, and the Universe becomes transparent for the first time. The first galaxies form at around 300 million years after the Big Bang, but the exact ...
