Black Hole
What happens to radio waves, time, and light in and near a black hole? Young scientists explore what is known about observing frequency and time at various distances from a black hole. They control the size of the black hole and the...
Curated OER
How Far... How Powerfu
Students work with a real optical spectrum of a gamma ray burst afterglow taken at the Keck Observatory. They measure the shifts of spectral lines, deduce the velocity of the astronomical object, and then use Hubble's Law to get its...
