Ethan Teng 🏳️‍🌈🏳️‍⚧️🇹🇼C/2022 E3 (ZTF)C/2022 E3 (ZTF) is a long-period comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) on March 2, 2022. The comet has a bright green glow around its nucleus, due to the effect of sunlight on diatomic carbon and cyanogen. It’s closest approach to Earth was on February 1, 2023, at a distance of 0.28 AU (42 million km; 26 million mi).<a href="https://mastodon.lol/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrophotography</a> <a href="https://mastodon.lol/tags/astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astronomy</a> <a href="https://mastodon.lol/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#space</a> <a href="https://mastodon.lol/tags/unistellar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#unistellar</a> <a href="https://mastodon.lol/tags/comet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#comet</a> <a href="https://mastodon.lol/tags/c2022e3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#c2022e3</a> <a href="https://mastodon.lol/tags/ztf" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ztf</a>

AkaSci 🛰️Here is a gorgeous composite image of the departing comet C/2022 E3 (ZTF) along with planet Mars taken two nights ago.The broad white dust tail and the long narrow blue ion tail are clearly visible. The coma shines brightly in green color at 518 nm wavelength, emitted by C2 (dicarbon) atoms.In the foreground is the Matterhorn, a mountain in the Italian Alps with a picturesque peak.Image Credit & Copyright: Donato Lioce Source: <a href="https://apod.nasa.gov/apod/ap230213.html" rel="nofollow noopener noreferrer" target="_blank">https://apod.nasa.gov/apod/ap230213.html</a> <a href="https://fosstodon.org/tags/comet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#comet</a> <a href="https://fosstodon.org/tags/APOD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#APOD</a> <a href="https://fosstodon.org/tags/C2022E3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#C2022E3</a> 1/n

AkaSci 🛰️Where to see comet C/2022 E3 (ZTF) in the night sky from central U.S. tonight. The comet will be visible near the Pleiades cluster. Mars will be visible within 2 degrees of the comet. See map below. Magnitude = 6, hence binoculars or a telescope will be needed.

AkaSci 🛰️Nice shot of Comet C/2022 E3 (ZTF), taken by Michael Jäger yesterday from Austria. Comet C/2022 E3 (ZTF) is still sporting its two tails (dust and ion) as it races away from the Sun to back home in the Oort cloud. <a href="https://twitter.com/Komet123Jager/status/1624157879564484608" rel="nofollow noopener noreferrer" target="_blank">https://twitter.com/Komet123Jager/status/1624157879564484608</a> <a href="https://fosstodon.org/tags/comet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#comet</a> <a href="https://fosstodon.org/tags/C2022E3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#C2022E3</a> <a href="https://fosstodon.org/tags/Astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Astronomy</a> 1/n

Robert SchwebelI've updated the C/2022 E3 blogpost with wednesdays' images, made with f=500 mm 1:3.6.The 30 min. stacking shows the gas tail nicely. It wasn't visible on the short-exposure ultra high ISO snapshots, so the picture orientation could have been better, but anyway.<a href="https://norden.social/tags/C2022e3" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#C2022e3</a> <a href="https://norden.social/tags/SIRIL" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SIRIL</a> <a href="https://norden.social/tags/Astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Astronomy</a><a href="https://schwebel.de/de/blog/2023-02-07-c-2022-e3.html" rel="nofollow noopener noreferrer" target="_blank">https://schwebel.de/de/blog/2023-02-07-c-2022-e3.html</a>

Jake 🇺🇸 🇵🇱This is my best photo of Comet C/2022 E3. This green comet passed Earth for the first time in 50,000 years. It was last visible in the night sky during the Stone Age. 48,000 b.c.e.But we have had gray skies forever (of course right?).Nikon D750, 510mm 80ED OTA on tracking mount.
