The Cosmic Web, Comet Highway, and First Deep-Sky Atlas

In the January 2022 issue of Sky & Telescope, we discuss what to look for when purchasing a lens for astrophotography. Unfortunately, we can’t take images sharp enough to spot the hidden filaments that connect galaxies using our new lenses. But professional telescopes are gradually revealing hints of these intriguing structures. While, astronomers have known about the cosmic web for years, they haven’t been able to observe it until now. If you’re up for a celestial challenge within range of amateur scopes, this issue has an observing scavenger hunt to test your deep-sky knowledge. We’re also diving into deep-sky history, specifically atlases. We sifted through antique star atlases to find the oldest one that can still help observers find deep-sky objects today.
