Plot of stars orbiting the center of the galaxy.

Evolution of a stellar mass black hole

Gravity waves are detected and we discover a new class of black hole.

Which came first?

3 Kepler Space Telescope

Kepler space telescope has discovered evidence of about 7,000 planets.

…almost 100 of them near Earth-size.

Our Solar system 12% of the planets in our system have communicating life.

Where’s home?

Mysteries 1.What is making the expansion of the universe accelerate? 2.Which came first, our Super- Massive Black Hole or the disk of stars, gas and dust of our galaxy? 3.Where is ET?
