AtLAST, a telescope that could reveal the missing half of the universe

A new European-led telescope could map the dusty, hidden half of the universe, all without using fossil fuels. If you have ever seen the Milky Way in the night sky, you probably noticed that it looks cloudy. That is because towards the center of our galaxy, and of most galaxies, there are vast amounts of dust that make it hard to see what is going on.
