Ask An Astronomer
Ever wondered why the Moon looks black during a solar eclipse? Or why they don’t happen every year? Well, we have your answer. Ask our resident astronomer, astrophysicist, and eclipse chaser Alex Filippenko, professor of astronomy at University of California, Berkeley.
An elected member of both the National Academy of Sciences and the American Academy of Arts & Sciences, Mr. Filippenko is one of the world’s most highly cited astronomers. We are thrilled he is part of our project, and
he will be answering questions leading up to and after the
eclipse so submit your question to Alex now.
Please be patient! On eclipse day, we may not answer questions immediately (because we are outside watching the eclipse and you should be too!) But we promise to get back to you soon, and we will be
archiving the answers to your questions here.
