Behold: the story of how our solar system began, in one chart. This is the second installment in a series of planetary scientists' favorite plots. Today's #FaveAstroPlot was suggested by spectroscopist Michael Bramble.
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.
How did planets originate? This is a question that has puzzled scientists for centuries, but one which they have been able to tackle directly only in the last few decades, thanks to two major developments: breakthroughs in telescope technology and ever-increasing computing power.
2012 VP113 is a new world that has been discovered on a Sedna-like orbit. What does that mean? It could imply the existence of a planet X, but doesn't prove it. It does suggest that a lot more Sednas are waiting to be discovered.
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.
