Comets Lemmon and SWAN are making their closest approach to Earth in a rare cosmic treat. Can you see it in NJ? Here's timing, tips, more.

Skywatchers can catch a rare glimpse of Comet Lemmon this month, and it won't be back until around the year 3175. Here's how and when to spot the sparkly green comet.

Comet C/2025 A6 (Lemmon) is this year’s brightest comet visible from Earth—an icy relic from the solar system’s origins that won’t return until the next millennium.

Chicago-area residents could be treated to a wonderful nighttime display as Comet Lemmon makes its closest approach to Earth in coming days.

It will be a while before you can see it for yourself, however. Halley’s comet was last visible from Earth in 1986, meaning we won’t have a chance to see it again until 2061. The comet is expected to appear in our skies around mid-June that year, Space.com reports, and remain visible into August.

Comet C/2025 A6 Lemmon is getting brighter and whether you have a telescope, binoculars or just your eyes, here’s how you can catch a glimpse.

C/2025 A6 (Lemmon) is the brightest of the three and was discovered on Jan. 3, 2025 by astronomers using the Mount Lemmon telescope near Tucson, Ariz. Initially, it wasn't expected to become particularly bright, but it began to intensify rapidly in August.

Comet C/2025 R2 (SWAN) is a new visitor from our outer solar system. It may be easier to see as it approaches Earth next week.

Harvard researcher Avi Loeb says comet 3I/ATLAS weighs 33 billion tons and spans 3.1 miles, making it far larger than previous interstellar visitors.
