Not one, but TWO paroxysmal eruptive episodes at #Etna 's Northeast Crater on 27 December 2025, AND minor activity at the Voragine crater. Though the Northeast Crater has frequently shown minor activity in recent decades, its last paroxysmal episode was on 27-28 March 1998.
Eruption column produced by the first paroxysmal eruptive episode at Etna's Northeast Crater, on the morning of 27 December 2025, recorded by a monitoring camera of the INGV-Osservatorio in Bronte, on the western flank of the volcano. Eruption column produced by the second paroxysmal eruptive episode at Etna's Northeast Crater, in the afternoon of 27 December 2025, recorded by a monitoring camera of the INGV-Osservatorio at the Montagnola, high on the southern flank of the volcano. Minor explosive activity from a vent on the east side of Etna's Voragine crater at sunset on 27 December 2025, recorded by a monitoring camera of the INGV-Osservatorio at the Montagnola, high on the southern flank of the volcano.

2 NEW epic images of Phobos over Mars just released by @esa.int Mars Express

This view is especially striking, with Phobos between the Tharsis volcanoes and Noctis Labyrinthus–Valles Marineris

Full resolution 300MP(!) & info on: flic.kr/p/2rMW4so

A wide view of the planet Mars fills the frame, shown as a curved, rust-colored world against black space. The bottom edge fades into darkness, marking the planet’s night side, while the upper portion is brightly lit by sunlight. Near the right side are three large, round volcanic mountains of the Tharsis region, each with a wide circular base and a darker central caldera, resembling shallow craters pressed into the surface. North of these volcanoes, stretching almost vertically across the upper right half of the planet, lies Noctis Labyrinthus and Valles Marineris: an immense system of deep canyons and fractured terrain that appears as pale, branching scars and cracks, partly softened by hazy, cloud-like atmospheric features. Near the center of the image, positioned between the volcanoes and the canyon system, a small dark oval appears against Mars’s surface. This is Phobos, one of Mars’s satellites. Its tiny size stands out sharply against the vast scale of the planet below.

HUBBLE SAW ASTEROIDS COLLIDING IN A NEARBY PLANETARY SYSTEM FOR THE FIRST TIME!! ☄️🌌
Image labeled Fomalhaut system, Hubble Space Telescope. A grainy orange oval ring tilts slightly from upper right to lower left. At two o’clock, a white box outlines the ring’s edge and white lines extend to a larger pullout at lower right. Two spots are labeled cs1 2013 and cs2 2023. Inside the ring is a black circle with a white star symbol in the middle.

A closer look at the coronal mass ejection produced by last night’s major solar flare. Some models are predicting that the eruption may have a minor Earth-directed component! #spaceweather

Was going through my old laptop and found this animation of comet Kudo-Fujikawa transiting the SOHO/LASCO C2 FOV! The images are from January 2003. Enjoy! ☄️

A look at big sunspot region 4294 as it rotates into view on Saturday. The region is currently producing occasional M-Flares and is likely a threat for an isolated strong X-Flare. SolarHam.com

Ich hatte mal überschlagen, dass eine ca. 2-3 Woche spätere Reaktion in D ca. 60.000 zusätzliche Todesfälle bedeutet hätte. Das scheint wohl mit dieser Schätzung aus UK übereinzustimmen.

Keep an eye on the sky tonight for the peak of Leonid meteors...also, the skies may stream with aurora once again. Massive sunspot region AR 4274 kicked off another X-class flare Friday. Here’s our post on what to expect for @universetoday.com - www.universetoday.com/articles/sun...
Sunday Night Doubleheader: Catch the 2025 Leonid Meteors and an Aurora Encore
Keep an eye on the sky Sunday night and early Monday morning for the Leonid meteors, and a possible second auroral storm. Once every other generation, the Lion roars. If skies are clear Monday morning...

Bei meinem gestrigen Post zu den #Polarlichtern handelt es sich leider um Lichtverschmutzung. Die Werte sahen ja gestern auch nicht so gut aus. Vielleicht auch ein Effekt durch den Saharastaub in der Atmosphäre?

Ich habe den Post deshalb auch mal wieder entfernt. Schön ausgesehen hat es dennoch. 🥲

Photographic red Aurora borealis from last night near Bielefeld (Germany).

Date: 12 November 2025
Time: Around 23:00 (CET)

The SOHO LASCO instrument is drowned in solar energetic particles due to the X5 flare earlier today Nov 11. A bit west of the disk center the particles are magnetically well connected to Earth. A massive #solarstorm was produced which we will model once initial conditions are available.

Resulting in a massive maximum total magnetic field of 63 nT, presumably the #solarstorm from Monday morning arrived 2025 Nov 11 23:38 at L1, and interacted with the previous storm just before it arrived at the L1 point near Earth. Dst reached - 238 nT, which is the 3rd strongest storm of this cycle

We just got an X5 flare from the same active region that launched the 2 #solarstorms earlier this week, at around 20 degrees north and west of disk center. We will again need to see whether a storm was launched with coronagraphs and then evaluate its potential arrival at Earth in the upcoming days.

A #solarstorm with an initial speed of ~730 km/s is on its way toward Earth! It’s associated with an X1.7-class flare that peaked today around 07:35 UTC.
The CME is expected to arrive Tuesday, 11 November, around 20:00 UTC (21:00 CET).
Let’s hope for a better aurora show than on Friday🤞🌌

☀️ Earth is currently experiencing a class G3 geomagnetic storm (likely caused by a #solarstorm flank hit), with Dst values going as low as -136 nT in the last 12 hours. Bz magnetic field component is currently positive, Dst values remain around -110 nT
Three plots showing current space weather conditions at Earth. The left-most plot shows the magentic field conditions, with a currently positive Bz component that was previously negative. The middle plot shows the Dst index, which currently sits at around -110 nT. The right-most plot shows the Newell coupling, which is currently at close to 0, but has peaked around 4.

I was worried for my crew mates when I saw them circling in the eye for over 20 mins. Looks like the very rough ride was confirmed. Plane had to leave early. They reported svr turb and a "sawtooth" eye. Looks like they moved 600-700ft up & down during this stretch in ~1 min.

You might’ve heard the news: SpaceX just passed 10,000 Starlink satellites launched. And that number is already old news, as there’s now a new Starlink batch launched every other day. Here’s what that looks like in a short animation of Comet A6 Lemmon courtesy of Michael Jaeger:

#Comet C/2025 A6 #Lemmon in the constellation Boötes, on the evening of October 24th. Captured from the light polluted outskirts of Munich.

16 minutes integration time with my Fujifilm X-S10 and 135mm f4.5 lens (untracked).

#astrophotography 🔭
A starfield with many small and colorful stars is dominated by comet Lemmon which is oriented diagonally in the frame. The comet has a greenish coma and a diffuse yellowish dust tail is pointing up from the nucleus. Layered with the dust tail is the blueish ion-tail which is much narrower and longer, stretching beyond the top of the image. The ion tail shows some slight undulations from changes in the comets activity over time.
