Martian robot spinning her turret!

A video sequence captured by the Perseverance rover using her Right Mastcam-Z science Camera on Jan. 27, 2024 (Sol 1044). The full sequence, accelerated here, actually took 3 minutes.

From @noirlabastro.bsky.social: Comet C/2024 G3 (ATLAS) gleams against the January sky above three NOIRLab-supported telescopes in this image. The last time it was visible from Earth was about 600,000 years ago. #astronomy

45 years ago today we got our first closeup of the Solar System’s very own “Death Star!” Captured by Voyager 1 on November 12, 1980 as it passed Saturn, this image (PIA01968) shows the moon Mimas with its 139 km wide, 5 km deep Herschel crater making it resemble the Empire’s infamous space station.

🔭 Très sympa cette galaxie du Triangle (M33) 🤩 Plein de nébulosités et plein de groupes d'étoiles dont certains un peu détachés de la galaxie. Mais pas simple à capturer et à traiter 😅

🔭 Encore un record pour le JWST : le 5e cycle de demande d'observations en compte 2935, contre 2377 pour le cycle 4 😅 Comme toujours, il n'y aura pas assez de temps disponible pour tout le monde. Lors du dernier cycle, seulement 274 programmes avaient été retenus 🥲

Dissecting the Perseus-Pisces supercluster observed with CFHT-MegaCam: Investigating environmental effects on galaxy morphology

by Maëlie Mondelin and co-authors
arxiv.org/abs/2511.05925 🧪🔭
This is Figure 2 of paper, featuring a sky-projected distribution of galaxies in the PPSC (Perseus-Pisces Supercluster) catalog. Grey dots represent galaxies from the PPSC catalog. Group and cluster centres identified are shown as gold points: from the left to the right in the region A, A 426, AWM7, a group with UGC 1841, and A 347. The projected skeleton, extracted from the final 3D structure, is represented by dark lines and traces the projected filamentary network. The boundaries of the region A and the region B are shown in purple and blue, respectively. A cyan contour indicates the footprint of the Euclid ERO Perseus field, overlaid for reference.

❄️ Earth isn’t the only planet to go through ice ages. The Red Planet experiences them too – as revealed in this new image from our #MarsExpress mission 🔴

Zoom in and explore the image in more detail 👉 www.esa.int/Science_Expl...
A section of Mars’s surface in shades of light brown and tan. It features several large circular craters scattered across the terrain, along with long, parallel ridges running diagonally from the lower left to the upper right. The ridges appear raised and rugged, while the craters are deep and round. The overall texture looks rough and uneven, suggesting erosion and ancient geological activity.

Mort de Tatsuya Nakadai, immense acteur du cinéma Japonais ! Il aura eu une filmographie sublime : Hara-Kiri, Kagemusha, Ran, Goyokin, Yojinbo, Sanjuro, La Condition de L’homme, Le Sabre du Mal, Rébellion, Après La Pluie. Un monstre équivalent à Toshiro Mifune et Takashi Shimura. RIP

#CometInterceptor will be the first mission to visit a comet coming directly from the outer reaches of the Sun's realm, carrying material untouched since the dawn of the Solar System.

Part of #CosmicVision, Comet Interceptor is an ESA-led mission in collaboration with JAXA.
