An Interactive Space Simulator
"Smash planets together, introduce rogue stars, and build new worlds from spinning discs of debris. Fire a moon into a planet or destroy everything you've created with a super massive black hole. You can simulate and interact with our solar system: the 8 planets,160+ moons, and hundereds of asteroids, the nearest 1000 stars to our Sun, and our local group of galaxies."

A computer aided simulation builds a spiral galaxy from its beginning
. In all, 390,000 particles were placed in an arrangement similar to a newborn galaxy. The end result after three months is an event that is believed to take billions of years to occur. (animation)

It ain't so dark anymore.
Dark matter seems poised to assume its place among those astronomical phenomena that were predicted to exist before being observed. The planet Neptune
and black holes
to mention two of them. The last 100 years have really been a boom time for astronomy, and they're not slowing down.
