I squinted on the western sky simply after darkish Monday evening and barely caught sight of the misty-looking tail of Comet C/2023 A3 (Tsuchinshan–ATLAS). It makes me want I used to be in a spacecraft with a can’t-miss view of our unusual celestial customer.
The European Space Agency shared a video on Tuesday from its sun-watching SOHO spacecraft that exhibits Comet A3 wanting like a glowing streak of sunshine. You possibly can even see an uncommon “anti-tail” optical phantasm.
The video covers the time interval from Oct. 7 via Oct. 13 and exhibits the solar blocked out within the center. Comet A3 — a cosmic snowball of mud, gases and ice — soars throughout the higher proper of the body.
“The comet’s nucleus is clearly seen, surrounded by a dusty coma and trailing an impressively lengthy tail,” ESA mentioned. “SOHO sees the big mud tail edge-on, curving in on itself as it’s pushed outward by photo voltaic wind.” The brilliant dot off to the left is the planet Mercury.

Watch via to the tip of the video and search for the skinny vivid line that reaches again to the solar. ESA says the “anti-tail” is a uncommon phenomenon.
“This tail is an optical phantasm coming from SOHO getting an edge-on view of the bigger cometary mud particles that accumulate within the comet’s orbital aircraft,” the house company mentioned. It resembles a laser beam capturing via house.
The solar is extremely energetic proper now and is kicking out flares and photo voltaic materials. These outbursts are seen within the video. The solar’s peppy temper has been triggering impressive auroras on Earth. Stay up-to-date on all the celestial events for October.

SOHO stands for Photo voltaic & Heliospheric Observatory. The sun-studying spacecraft is a joint mission from ESA and NASA. It launched in 1995. Comet A3 is the second brightest SOHO has ever witnessed. The highest honor goes to Comet C/2006 P1 (McNaught) in 2007.
Comet A3 will get progressively more durable to identify from Earth, however Northern Hemisphere skywatchers can look to the west after sundown (attempt binoculars). Even should you miss it, you’ll be able to nonetheless benefit from the views from the International Space Station and from the SOHO spacecraft. Comets are a uncommon deal with, so make sure to say hi there to A3 earlier than it strikes on.
