Galaxies
How galaxies formed and evolved to become the beautiful objects we see today is a very hot topic in current astrophysics. This question is deeply connected to cosmology and the origin of the universe. Research in this area extends from the center of our own galaxy, to the end of the "dark age", when the first stars and galaxies in the universe were formed.

Supernovae
Most massive stars and some less massive stars in close binary systems end their lives in giant explosions, so-called supernovae. A supernova is seen as a new star in a distant galaxy, which first becomes brighter for a few weeks and then slowly fades. Remnants of previous supernovae can be seen in the Milky Way and nearby galaxies.
