🔭 Dione and Rhea Ring Transit

Image Credit & Copyright: Christopher Go

apod.nasa.gov/apod/ap25112...
Seen to the left of Saturn's banded planetary disk, small icy moons Dione and Rhea are caught passing in front of the gas giant's extensive ring system in this sharp telescopic snapshot. The remarkable image was recorded on November 20, when Saturn's rings were nearly edge-on when viewed from planet Earth. In fact, every 13 to 16 years the view from planet Earth aligns with Saturn's ring plane to produce a series of ring plane crossings. During a ring plane crossing, the interplanetary edge-on perspective makes the thin but otherwise bright rings seem to disappear. By November 23rd Saturn's rings will have reached a minimum angle for now, at their narrowest for viewing from planet Earth, but then start to widen again. Of course, Dione and Rhea orbit Saturn near the ring plane once every 2.7 and 4.5 days respectively, while the next series of Saturn ring plane crossings as seen from Earth will begin again in 2038.

Se han recuperado unas imágenes inéditas de Federico García Lorca viajando con su compañía "La Barraca" llevando teatro y cultura a nuestros pueblos... y ¿cómo no? en una de sus representaciones aparece rodeado de constelaciones😀

Interstellar Comet 3I/ATLAS is fragmenting on its way back out from the Sun. 🧪🔭

www.virtualtelescope.eu/2025/11/13/c...
The image of Comet ATLAS comes from the sigma-clipping combination of 15, 60-second unfiltered exposures, remotely taken with the Celestron C14+Paramount ME+SBIG ST-10XME robotic unit available as part of the Virtual Telescope Project in Manciano, Italy. To keep the highest detail, we shortened the exposure time and, looking at the results, we are happy with that choice.

ESA’s Mars and Jupiter missions observe comet 3I/ATLAS

@esa.int is making the most of its interplanetary missions to observe the comet from multiple vantage points. 🧪🔭

Infographic showing the path of comet 3I/ATLAS, the third known interstellar object to enter our Solar System. It displays the orbits of Earth, Mars and the Juice spacecraft around the Sun, along with key dates and events as comet 3I/ATLAS travels through the inner Solar System in 2025. Coloured and numbered dots mark important observation points by telescopes and spacecraft.

Perdonad el offtopic pero me descorazona que ni siquiera dejen ayudar altruistamente.

Fui voluntaria de una ONG muy similar en Madrid, repartiendo bocatas por el centro. Necesitan esa pequeña ayuda, más por socializar con ellos, que por la comida en sí, que también.

The suspicious rock, named "Phippsaksla" by the mission team, was targetted by the SuperCam instrument, revealing that it is high in iron and nickel, suggesting it formed elsewhere in the solar system.

But wait, there's more... ULA is also launching an Atlas V rocket from the Cape in just over an hour, with ViaSat-3 F2: www.youtube.com/watch?v=L5Dy... Should be a good nighttime launch for the Florida Space Coast. Strange to have two Cape launches in one day...and neither was SpaceX.

Lots of folks captioning aurora photos like "for a few minutes we didn't think about politics"

guess I'm built different, every time I'm out trying to see night sky stuff I frequently think about how much light pollution is entirely preventable with just a tiny bit of regulation
Basic light pollution diagram showing four different streetlight set ups ranging from more light pollution on the left to less light pollution on the right. The most pollution option, labelled "very bad" is a street lamp with a round uncovered bulb on top, making a sphere of light in the air. The next option, labelled "bad" has a tiny cap on top, that limits the upward pollution a bit. The "better" option is mostly uncovered on top, limiting pollution above the streetlight. The final option, labelled "best" has a full shroud overtop, limiting the light to only below the streetlight, where it is needed for pedestrians and vehicles.

The Sun just produced an X5.1 class #SolarFlare. This is the largest flare of 2025 so far, and 6th largest of the past two years. It triggered a strong ‘Radio Blackout’ and moderate ‘Solar Radiation Storm’ at Earth, and released what is most likely an Earth-directed coronal mass ejection!
