In 2011 Daniel Holz gave a Heinz R. Pagels Public Lecture at the Aspen Center for Physics on the topic of Gravitational Waves. The talk is one of the better explanations of what this is all about, with a bonus introduction!

LIGO explains

February 11th was a good day. I spent the day at the “Dynamics and accretion at the Galactic Center” Conference at the Aspen Center for Physics, where about 75 physicists have spent the week talking about black holes and stuff. This morning we watched the LIGO press conference, frantically deciphered the papers, and had a…

A New Kepler Orrery

Ethan Kruse has update the Kepler Orrery, just in time for Extreme Solar Systems III now under way. Enjoy

Skrekkur is an annual talent show for Icelandic schools, roughly 9-10th grade, and it has grown to become quite a big deal. The winning act is usually stunning and original and very well executed, and I don’t just say that ’cause my little cousins keep winning… This year the winning performance, from Hagaskóli, was extraordinary,…

The Dance of Neptune

The Kepler 2 mission serendipitously observed Neptune about a year ago. The images were posted on the K2 website, but according to the website stat like nobody shared them, which sucks. The animation was just shown at the Division for Planetary Sciences meeting, #DPS15, in DC so it is time to show it again. Enjoy.…

As of this morning we have discovered over 1,500 exoplanets, planets orbiting stars other than the Sun. In addition to the confirmed discoveries, we have over 3,000 candidate exoplanets, most discovered by the NASA Kepler Mission through transits, where we see the shadow of a planet as it crosses in front of its parent star.…
