Sky & Telescope July 2022 Magazine
In the July 2022 issue of Sky & Telescope, we explore a set of lesser-known globular clusters. Then we take a dive into worlds with more than one Sun — once the stuff of science fiction, astronomers now know of hundreds of these potential real-life Tatooines. While some scientists examine planets around far-off stars, other astronomers are still hunting for planets in the distant edges of our solar system. Does a ninth planet exist? The search for Planet X continues as astronomers pluck more and more Kuiper Belt objects out of the murk. Finally, if building a telescope to pick out those distant stars and galaxies isn’t enough of a challenge, it’s time to grab some grit and start grinding: We’re pushing glass to new horizons with a guide to the basics of mirror grinding.
