The traditional image of the astronomer peering through the eyepiece of a telescope and recording data is badly dated. Modern astronomy makes use, not only of the light our eyes can perceive, but of radiation across the electromagnetic spectrum, from radio waves to gamma radiation. At the end of the 20th century, astronomers learned how to use what amounts to star-quakes to peer inside the sun and deduce its internal structure.  Most amazingly, in the last few years we have learned how to detect gravity in its radiant form, so that we can now see the darkest objects of all: black holes.  In this presentation, Professor Balbus will review these achievements and speculate on what the future will bring.
