The Kepler Space Telescope multiplies the galactic real estate available for study. Others are learning to read the atmospheres for traces of water. How long before we confirm an alien earth? Astronomy keeps getting more exciting. Waiting for the James Web Telescope coming down the pike.
Enjoy the wonder.
