Short loop showing the development of AR 4290 (right) and 4291 (left) over the past few days. I absolutely love watching how these things progress and grow, they're mesmerizing!

Found a visual of the lake-effect lightning in Buffalo this evening! Flash can be seen toward the left side of the screen. Video from @BTPMPBS #nywx @NWSBUFFALO ❄️⚡️

Quite the impressive loop of lake-effect lightning this evening in the #Buffalo area. Mixed-phase region well into these clouds with graupel observed #nywx #onstorm

Bouncing with the blast wave! Check this high detail (denoised) view of a massive filament stretching like a solar skyscraper high above the Sun's surface. A farsided solar storm launch causes this springy structure to bob up and down in the wake of the blast. Some material even

The far side of the Sun looks pretty busy (in JSOC Time-Distance Helioseismic Far-Side Imaging data). Active region 4274 is still there, as are at least 3 more active regions, including 4281. They will rotate into view in about 4-5 days. AR 4274 is certainly quite long lived, if

アトラス彗星 C/2025 K1(ATLAS) 2025年11月13日～23日(UT)の頭部変化GIF 主核の小バースト→C核の分離→B核の減衰が捉えられました。 スタック精度の点から、核の形状に曖昧さが生じていると思います。

Impresionante Meteoro diurno a las 6:15pm Un brillante meteoro se apreció este domingo desde toda la Isla mirando en dirección al Este, indicó la Sociedad de Astronomía del Caribe (SAC). Varios de los testigos aseguran que percibieron un sonido o estruendo varios segundos después

2025年11月24日18時50分50.1秒の閃光を別のカメラで撮影した様子です(270fps,0.03倍速再生)。この時、月の高さはわずか5度しかありませんでした。

昨夜は月面衝突閃光が出現しました。2025年11月24日18時50分50.1秒の閃光です(100fps,0.1倍速再生)。月は大気がないため流星や火球が見られず、クレーターができる瞬間に光ります。落下場所は、アリスタルコスクレーターの北西のスキャパレリCクレーターの近傍で、おうし座流星群の衝突領域内でした。

Terminal Doppler out of IAH has captured the life cycle of potentially two tornadoes from this cyclic supercell moving through the NW Houston Metro. Impressive, high-res, low level data with high frequency updates! #txwx

This time-lapse uses almost 20 years of images from ESO’s Very Large Telescope in Chile to track real stars orbiting the supermassive black hole at the centre of the Milky Way. Gravity written as motion.

Here is a 40 minute time lapse of interstellar comet 3I/ATLAS from yesterday morning's webcast, along with a stacked image!

Another polar prominence lifted off from behind the Sun’s north pole.

Meteors from last night/this morning. I really like the ones that leave green trains.

Earth just got hit by one of the strongest solar flares in over a year 🌞⚡️ On Nov 11, an X5.1-class flare erupted from the Sun — the biggest of 2025 so far — launching a coronal mass ejection that slammed into Earth on Nov 12 and kicked off a severe geomagnetic storm. The
