The top right asterism in the #comet sequence shared below can be used for comparison with my today's 8 min. images with #S50. The bar in the 2nd image is 20 arcmin wide, indicating the telescope field of the animation. Details & update @es.theconversation.com theconversation.com/el-cometa-20...

A lo largo de las próximas semanas, se mostrará moviéndose noche tras noche prácticamente paralelo al horizonte. @joseptrigo.bsky.social (@ice-csic.bsky.social @ieec.cat) nos cuenta más: 

El #cometa #PANSTARRS cada matí més espectacular i ja accessible a ull nu. La imatge que porto avui és de 7 min. d'exposició i mostra detalls a la cua iònica.

A 15 min. image of #C2025R3 #PANSTARRS on Apr. 10th, 4h15-30 UTC from #MontsenyObservatory. The plasma tail here extended for about 1.5° (longer than 5° using binoculars from Bortle 4-5). Already showing an amazing coma structure. Enjoy them at carillon-dahlia-r2by.squarespace.com/gallery/comets

#COMETA 2025 R3 #PANSTARRS AMB LA SEVA CUA IÒNICA des de Breda, Girona, #Catalonia la matinada d'ahir, 10 d'abril. Una altra fotassa de Pau Montplet i Sanz @AstroBreda in X. Just 25 min. d'exp. en fotos de 60 s amb ASKAR FRA400 (F3.8), Player One Ares-C PRO, filtre Optolong L-PRO👌👇 🤩☄️ His 3rd #apod?

Today image of #comet 2025 R3 #PANSTARRS, from #MontsenyObservatory with its coma in magn. +5, and several degrees of tail. Just in one week we will be amazed without Moon and approaching! theconversation.com/el-cometa-20...

Crescent Moon and Crescent Earth from Artemis II. 🔭 🧪 #astrophotography #ArtemisII

#PPOD: A red-green-blue image of 3I/ATLAS taken by Juice’s high-resolution science camera, JANUS, from more than 180 million km away. The comet seems to glow green because gases in the halo around the nucleus emit light at green wavelengths. 🧪 🔭

It's been a bad week for a lot of people, but also a bad week for Flat Earthers and Moon Landing Truthers. #science #astronomy #conspiracy

Holy sh*t. A solar eclipse, seen for the first time by human eyes during a lunar flyby. The Earthlight illuminating the crescent of the moon and part of the spacecraft, the stars and planets in the background…I’m in tears 🤯 📸: NASA 🔭🧪

Probably an early stage of an ongoing outburst in comet #29P tonight (image on left), noticed using #S50 and looking at the bright false nucleus compared with its fully diffuse appearance on April 3th on right. #MontsenyObservatory carillon-dahlia-r2by.squarespace.com

El cap de la constel•lació d'Orió conté un cúmul obert de 40 estels, amb el més lluminós dit Meissa. Aquests estels blaus van formar-se d'un mateix núvol fa 5 milions d'anys i són a 1300 anys de llum de nosaltres. Foto de 20 min feta avui🤩 #MontsenyObservatory carillon-dahlia-r2by.squarespace.com

C/2025 R3 TAIL DISCONNECTION imaged today from #MontsenyObservatory. Such events are produced when the ion tail is severed from its coma (now in +6 magnitude), caused by interaction with gusty solar wind or coronal mass ejections. To find it, please visit: theconversation.com/el-cometa-20...
