Why is it so hard to predict solar eclipses? How did Newton and Halley team up to solve it? What have we learned from solar eclipses since then?
On July 2nd, a total solar eclipse passed over Cerro Tololo Inter-American Observatory in Chile. A team of students from the University of La Serena attemped to recreate the Eddington Experiment that provided the first experimental evidence for Einstein’s General Theory of Relativity.
On July 2, the path of totality of a total solar eclipse will cross the Pacific Ocean, including Oeno Island, and then cross Chile and Argentina. The observations at this minimum phase of the sunspot cycle will provide important information about the solar corona, and will fill in the ordinary gaps between on-disk extreme-ultraviolet imaging and satellite imaging of the outer corona.
To test Albert Einstein’s prediction, with his General Theory of Relativity, with observations from the total solar eclipse of May 29, 1919, observers led by Arthur Eddington went to Principe.
A lunar eclipse, a conjunction between Jupiter and Venus, and two good lineups of planets bookending the month make January a spectacular month to go out stargazing, if you don’t mind the cold.
Mass goes missing in BH collisions? Is a solar eclipse useful for science?
Pamela and Fraser talk about What to do, and (perhaps more importantly) what NOT to do during Solar Eclipse!
