June’s Annular Solar Eclipse, Starlink, and Urban Deepscapes
In the June 2021 issue of Sky & Telescope, we’re getting ready for the annular solar eclipse over Canada and the North Pole this month. Joe Rao guides us on how and when to see the Moon’s shadow pass over the Sun. And we report how SpaceX is working with astronomers to mitigate the negative impact of their satellites on astronomy. However, individual companies’ amity won’t be enough to forestall the growing light pollution as tens of thousands of satellites hit the skies in the next few years. Also in this issue, Marybeth Kiczenski explains the “deepscape” technique she used to capture the image of Comet NEOWISE (C/2020 F3) over the Mackinac Bridge, featured in the November 2020 issue. While we enjoyed the comet’s show last summer, astronomers were studying comets in other star systems. We discuss their discoveries along with some interesting new information about the Milky Way’s largest satellite. Several discoveries over the past decade have forced scientists to revise our understanding of the history of the Large Magellanic Cloud.
