The best time to catch a glimpse of Neowise was in early July, just after it made its closest approach to the sun and reached peak brightness. The comet has grown noticeably dimmer over the past few days as it moves away from the sun, but if you haven’t had a chance to check it out yet, it’s not too late. Neowise makes its closest approach to the Earth on Thursday, and if you live in the northern hemisphere you’ll still be able to see it with your naked eye for a few more days. We asked amateur astronomers for their best tips on how to go comet-spotting.

There’s no telling how quickly it will fade from view so get out and see it as soon as you can.
