Black holes, white holes and worm holes are all consistent with Einstein's theory of General Relativity. Of the three, actual evidence exists only for black holes. Their behavior is explained. Scientists speculate on on whether white holes and worm holes exist and how they would behave.

Scientists hunt for dark matter in the strangest of places. They know where it is, what it does and can sort of see it if they look in the right way. They just can't quite figure out what it is or how to get their hands on it even though it's everywhere. But it is well understood compared to dark energy which is an even bigger mystery.

Although supernovas are associated with the death of stars they also seed the universe with heavy elements that comprise rocky planets like Earth and living creatures. Due to their extraordinary brightness supernovas have a recorded history dating back 2,000 years. Although closely studied for decades their infrequency has permitted only a general understanding of their behavior until very recently. New computer models can model the major details of the explosion while new exploratory techniques reveal many more events including some truly super supernovas.

They are the crown jewels of the galaxy. Neither stars, planets, moons or asteroids, they are the mysterious clouds of gas we call NEBULAS. Nearly invisible to the naked eye, astronomers use the most sophisticated techniques to tease images of these fascinating phenomena from the dark sky. When revealed in their full glory, they glow, reflect or obscure the galaxy's light.
