In case you haven’t heard … Comet C/2023 A3 (Tsuchinshan-ATLAS) – aka Comet A3 – is in the evening sky! And it’s the brightest comet in 27 years, the brightest since Hale-Bopp in 1997. Look to the upper right of the bright planet Venus for Comet A3 and its long wispy tail. Our charts are mostly set for the northern half of Earth. To see a precise v...
Comet A3 has an anti-tail! Can you see it? An ordinary comet tail always points away from the sun. That’s because comet tails are created by the pressure of solar radiation and by the solar wind streaming from our star. But – during the period around October 13 to October 15, as we cross the plane of the comet’s orbit – Comet A3 is exhibiting a rar...
Stay tuned, because we might have another bright comettoward the end of October. EarthSky’s Deborah Byrd, Dave Adalian and Marcy Curran have more in the video below. Here’s the lowdown on not one comet – but two comets – possibly visible in Earth’s skies in October and early November 2024. EarthSky’s Deborah Byrd, Marcy Curran and Dave Adalian have...
In September and early October – for Southern Hemisphere observers with dark skies and good optical aid – Comet C/2023 A3 (Tsuchinshan–ATLAS) put on a fantastic show in the morning sky. Amazing images of A3 in the morning here. Then A3 was lost in the sun’s glare for a few days. Now it’s back, quite low along the western horizon as soon as the sun ...
The comet was closest to Earth in its orbit on October 12, 2024. At that time, it was between us and the sun, putting on a heck of a show in solar telescopes. And some people even managed to catch it near the sun. See images below.
Comets are unpredictable. And Comet A3 isn’t going to be a Comet of the Century. But if it continues to perform well, it might be the brightest comet of the year … except for one other possibility. There is a second comet in Earth’s skies that might become bright, if it’s not disintegrating. The ATLAS telescope also discovered Comet C/2024 S1 (ATLA...
1. Be sure you’re looking at the correct direction and time.Comet A3 will be visible low in the west after sunset beginning around October 14.

4 days ago · Two bright comets visited the inner Solar System in October 2024: one of them (C/2023 A3) has become visible to the naked eye, while another one (C/2024 S1) didn’t survive its encounter with the Sun. The next promising comet is C/2024 G3 (ATLAS), which may become visible even in the daytime sky by mid-January 2025!
2 days ago · The brightest comet in over a decade is still visible in the night sky! C/2023 A3 (Tsuchinshan-ATLAS) is fading away, leaving the inner Solar System, but if you grab a pair of binoculars, you can still catch it in the evening over the western horizon.
