Life in the Universe
The Earth gives us a ringside seat on the physical, chemical, geological, and biological evolution of a dynamic terrestrial planet. The abundance of terrestrial planets in remote solar systems motivates the search for life and technology elsewhere in the universe.
Astronomy: Exploring Time and Space
Welcome to Astronomy: Exploring Space and Time! The course is designed for anyone who is curious about the latest insights into the universe. The subject is progressing at a breathtaking pace, with discoveries being announced almost daily. Moving outward, here is a partial list: growing evidence that Mars was warm and wet in the past, the first soft landing on a comet, our first close-up look at the surprising dwarf planet Pluto, new insights into how stars form, the prospect of probing the event horizon of the black hole at the center of our galaxy, a census of twenty billion habitable worlds in the Milky Way, better constraints on dark matter and hints at the nature of dark energy, and the detection of a starburst galaxy within 5% of the age back to the big bang.
This course will acquaint you with the tools of the scientific method, and the innovations in optics that are leading to a new generation of huge telescopes. You’ll learn about the prospects for life in the Solar System, the future of space travel, the exotic end states of stars, the large-scale architecture of the universe.
