You’ll Only Have One Chance to See This Celestial Event in Maine, New Hampshire, & Massachusetts

Even though they do not happen every day, or night, celestial events are a pretty common occurrence.

There is at least one full moon per month, we get several meteor showers per year, and, if you're willing to travel, you can witness a solar eclipse once every few years.

Sometimes, however, we have the chance to witness a once-in-a-lifetime solar event.

That's the case with C/2025 A6, a comet making a pass by Earth this month.

Where Can I See Comet Lemmon?

According to an article on the Vice website, Comet Lemmon (AKA C/2025 A6) was first spotted back in January by Arizona’s Mount Lemmon Survey, and now it’s getting ready for its big moment.

Around October 21, the same night as the new moon, it’s expected to reach peak brightness. That means you should be able to see it without any binoculars or a telescope.

Just step outside and look for a soft green glow in the sky.  That unique color comes from carbon molecules in the comet’s coma reacting to sunlight.

You'll see the comet near the constellation Ursa Major.  Right now, it is visible in the pre-dawn skies, but it will soon start being visible in the evening skies.

Seeing this comet is truly a once-in-a-lifetime event because the comet will not pass through our piece of space again until 3,175 AD.

Comet Lemmon is not the only comet in our area this month, though.
