The views you get when you're closer to the Sun! 😎 Here's @MissionSoho looking at the now famous Comet C/2023 A3 (Tsuchinshan–ATLAS), the second brightest comet the mission has ever seen 👇 youtube.com/watch?v=OTrvT5oz…

Comet C/2023 A3’s brightness is ‘off the charts’ today, partially saturating @MissionSoho’s detectors! 😎 ✨Those sparkles in the image are solar energetic particles, as the Sun is still bursting with activity 📷ESA/NASA SOHO

Aaaand.. Action! ☀️ In the last 24 hours, the Sun sent out two X-class solar flares and @MissionSoho witnessed the two associated coronal mass ejections – those big white “puffs” seen here. And that big white streak on the right? That’s Comet A3 entering the scene ☄️ 🎥ESA/NASA SOHO

☄️Comet alert! For the next few days, @MissionSoho will be watching Comet C/2023 A3 (Tsuchinshan-ATLAS), expected to be one of the brightest comets it's ever seen. Teaser first image below, check the right edge! 📷ESA/NASA SOHO (☀️centre, Mercury on the left)

Además de investigar cómo funciona el Sol, @MissionSoho es el descubridor de cometas más prolífico de la historia de la astronomía ☄️ Ha seguido el destino de miles de estos minimundos helados en sus ardientes encuentros con el Sol. 👇

In addition to investigating how the Sun works, @MissionSoho is the most prolific discoverer of comets in astronomical history ☄️ It has tracked the destinies of thousands of these icy mini-worlds as they endured fiery encounters with the Sun. Here's SOHO's 4000th comet. Its 5000th is just around the corner... 📽️ ESA/NASA/SOHO/K. Battams

It's official – @MissionSoho has hit 5000 comets! ☄️ Spotted on 25 March by citizen scientist and seasoned comet hunter Hanjie Tan, this rare 'Marsden group' comet is extremely small and faint. See the comet next to the Sun 👉 esa.int/ESA_Multimedia/Image…

Avvistata il 25 marzo da Hanjie Tan, 'citizen scientist' ed esperto cacciatore di comete, questa rara cometa del "gruppo Marsden" è estremamente piccola e debole. Nell'animazione video, la troviamo tra le due linee verticali nel riquadro in altro a sinistra. @MissionSoho

La missione @MissionSoho è stata progettata per l'osservazione del Sole 🌞. L’abilità del telescopio come 'cacciatore di comete' ☄️ è un successo inaspettato. Rivediamo con @esascience le comete 4.000, 3.000, 1.500 e 750 di SOHO. ⬇️

Replying to @esascience
During its three decades in space, SOHO has become the most prolific discoverer of comets in astronomical history. Designed to observe the Sun, the telescope’s prowess as a comet-hunter is an unexpected success. (Pictured: SOHO's 4000th, 3000th, 1500th and 750th comets)

🌞 🌚 🌎 The ESA/NASA SOHO mission observed its 5000th comet ☄️ - found by a member of the public through the @SungrazerComets project! The instrument used was LASCO, which creates an artificial eclipse in space! Dr. Karl Battams leads the project. 🥳 👏 go.nasa.gov/4cwGWmu

“Sungrazer has been with me my entire career, so to see it get SOHO to this milestone is beyond thrilling. I'm delighted for all the project volunteers who, over the past 20 years, have made Sungrazer so engaging, inspiring, and rich with science.”
