Gravitational Waves, Distorted Galaxies, and Drawing in the Dark
In the June 2022 issue of Sky & Telescope, astronomers are using gravitational waves to stretch our understanding of black holes. From colliding black holes to merging galaxies, we zoom out a bit to look at some captivating, distorted galaxies. We have also selected stunning images of geological formations that are a little closer to home: Can you guess which solar system body hosts each one? Plus, Howard Banich and Ron Brecher might have different ways of capturing their favorite observing targets, but they’re both more than happy to share their skills with you. Banich reveals the techniques behind the incredible sketches he has shared with us over the years, while Brecher covers the ins and outs of color in deep-sky astrophotography.
