Ok, let's get started 😊🛰️

Most of You already know me, so there's no need to introductions.

I'll start with a megathread of my favourite satellite pics processed by me in 2024.

Various dates, most of them were taken by Sentinel-2.

W wyniku nocnego ataku na TANTK im. Berijewa w Taganrogu zniszczono 2 samoloty:

-A-60, eksperymentalne latające laboratorium, nośnik broni laserowej
- Il-76 ciężki samolot transportowy

Znaczne uszkodzenia odniosła również fabryka, w szczególności hala końcowego montażu.

Yesterday, an ash plume could be seen rising from the #HayliGubbi 🌋 #Volcano region. The eruption had stopped earlier, but the ash plume had been sent up into the atmosphere and was moving at a speed of 100-120 km/h toward North #India.

Fall Collection from Chandra

Four images that one can imagine connections to fall have been released by Chandra (ALT for images description)

A cornucopia is a horn-shaped basket that traditionally carries fruits and vegetables. There is nothing edible in this pair of galactic cornucopias but there are a bounty of stars, dust, and other ingredients than make up these two spiral galaxies, known as NGC 2207 (right) and IC 2163 (left), that we see face-on. This view of NGC 2207 and IC 2163 takes a James Webb infrared image (white, gray, and red) and adds the X-ray view from Chandra (blue). Together, it is quite an eye-catching result. Credit: X-ray: NASA/CXC/SAO; Infrared: NASA/ESA/CSA/STScI/Webb; Image Processing: NASA/CXC/SAO/L. Frattare Multiple telescopes teamed up to capture an image that looks like a cozy sweater with fuzzy arms. X-rays from Chandra and ESA’s XMM-Newton (purple), optical light data from Hubble and the Very Large Telescope in Chile (orange, red, and violet), and an optical image from astrophotographer Bob Fera (deep blue) combine to reveal R Aquarii. Nestled within the cozy ‘body’ of R Aquarii is a pair of stars where a white dwarf is pulling material from a much larger red giant companion. When enough material accumulates on the surface of the white dwarf, it triggers an outburst that sends a jet out into space. Over time, these jets twist and loop around each other weaving the structure seen today.

Frattare NGC 6334: COSMIC LEAVES BLOWING For many, nothing evokes fall more than fallen leaves. In this view of NGC 6334, glowing pockets of dust and gas in the nebula resemble leaves that have been picked up by a wind gust. This region is actually home to strong winds blowing from the young stars that have formed there. This image contains X-ray data from Chandra (blue, green, and yellow) that shows the effects of these winds, which have been combined with infrared data from the now-retired Spitzer Space Telescope (red, brown), which shows the dust and gas that fuels the growing stars. Credit: X-ray: NASA/SAO/CXC; Infrared: NASA/JPL/CalTech/Spitzer; Image Processing: NASA/CXC/SAO/J. Schmidt Born after a violent explosion of a star, this cosmic gourd is the supernova remnant G272.2-03.2. X-ray observations (orange and magenta) from Chandra provide evidence that G272 is the result of a Type Ia supernova explosion, where a white dwarf star pulls material from a companion star until it triggers a thermonuclear explosion and obliterates the star. The inside of the “pumpkin” is superheated gas that is filling the space cleared out by the explosion as it moves outward.

An explosive #eruption of Hayli Gubbi #volcano, located SE of Erta'Ale in the Afar Rift (Ethiopia), began at ~08:30 UTC on Nov 23. Eruption onset was fortuitously captured by a @planet.com overpass at 08:31 UTC. Hayli Gubbi has no record of Holocene eruptions. Toulouse VAAC reporting ash to ~15 km.

Derived Ash Height product from @eumetsat.int #meteosat10 suggested that parts of the volcanic ash cloud from the eruption of #HayliGubbi in Ethiopia may have reached heights in the 18-20 km range (black).

As far as the weather forecast goes, it looks like I only had one hour to try to get a pictures of interstellar comet 3I/Atlas.
And it worked!
Even the tail is faintly visible.
It looks like typical comet even with small equipment - Olympus E-M1II with 75-300 mm lens and Minitrack LX2 tracker.
Long exposure image composite of interstellat comet 3I/Atlas. The comet is visible like green spot with a faint tail in the center of the image with star trails around it. Total exposure around 50 minutes. The source images for the composite image were taken on November 19, 2025.

Here's a view by #Sentinel-2 of the Rhone river plume within the Gulf of Lion waters. Other the change in water colour, and the strong front between the two water masses, I love how there are more wind-induced whitecaps in the bluer waters, although I do not have a direct explanation about it... 🧐🌊
