Learn about the formation and origin of the Solar System and go beyond our neighborhood to investigate exoplanets (planets around other stars) in this video of class 11 of Bruce Betts' Introduction to Planetary Science and Astronomy class.
Cosmos returns in fine form in its penultimate episode. Sagan explores the historical and scientific precedents for the search for extraterrestrial life (SETI) and our human desires to not be alone in the universe.
The astronomy world is all a-twitter this morning over the discovery of a new supernova in M82, a galaxy that's in our astronomical backyard, "only" 12 million light-years away. And early word is that it appears to be a Type Ia supernova, the kind that's used as a standard candle to measure the expansion of the universe.
CosmoAcademy — a project from the CosmoQuest educational and citizen-science group — is offering three new online classes: Introduction to Dark Matter, Introduction to Astronomy via Color Imaging, and Life Beyond Earth: Introduction to Astrobiology.
This episode highlights the other big idea in Cosmos: that we are profoundly connected with the universe around us. Our constituent parts are forged in the bellies of massive stars; we exist through their deaths.
