@AkaSci It lets me feel quite old but I hope that my body will work also enough time. 🤭 I remember well the start and Carl Sagan's idea how to communicate with alien civilisations: https://en.wikipedia.org/wiki/Voyager_Golden_Record
Voyager1 and @voyager2 were a milestone!

Welcome to a Comet, from Lander on Surface
The Philae lander of the European Space Agency Rosetta mission is safely on the surface of Comet 67P/Churyumov-Gerasimenko, as these first two images from the lander CIVA camera confirm. One of the lander three feet can be seen in the foreground.

Angling Saturn
The Cassini spacecraft takes an angled view toward Saturn, showing the southern reaches of the planet with the rings on a dramatic diagonal. The moon Enceladus appears as a small, bright speck in the lower left of the image.

A digest gets finished only if it is narrow.
Newest on the shelf: mean-motion resonances, first half of 2026. One question, one window, one curator going through what came out and rating it.
Not "everything important this month" — that is a promise we could not honestly make. AI finds and summarises; the verdict on each paper is a person's.

Rosetta Mission Selfie at 30 Miles
The Philae lander of the European Space Agency Rosetta mission took this self-portrait of the spacecraft on Sept. 7, 2014, at a distance of about 30 miles 50 kilometers from comet 67P/Churyumov-Gerasimenko.

Circles and Hexagons
Saturn's cloud belts generally move around the planet in a circular path, but one feature is slightly different. The planet's wandering, hexagon-shaped polar jet stream breaks the mold -- a reminder that surprises lurk everywhere in the solar system. This atmospheric feature was first observed by the ...

Dione Deception
At top of this image, Saturn moon Dione may appear closer to the spacecraft because it is larger than the moon Enceladus in the lower left. However, Enceladus was actually closer to the spacecraft in this image captured by NASA Cassini spacecraft.

The first light of MOONS!
Mounted on our VLT in #Chile, the scientific instrument Multi-Object Optical and Near-infrared Spectrograph (MOONS) has successfully made its first observations.
During its ten-year design lifetime, it is expected to observe up to ten million objects.

Ammonia Clouds on Jupiter
In this movie, put together from false-color images taken by the New Horizons Ralph instrument as the spacecraft flew past Jupiter in early 2007, show ammonia clouds appearing as bright blue areas as they form and disperse.

Saturn and 4 Icy Moons in Natural Color
This approximate natural-color image shows Saturn, its rings, and four of its icy satellites. Three satellites (Tethys, Dione, and Rhea) are visible against the darkness of space, and another smaller satellite (Mimas) is visible against Saturn's cloud tops very near the left horizon and just below the rings. The dark shadows o...

Early Voyager 1 Images of Jupiter
These Jupiter photographs are part of a set taken by NASA Voyager 1 on December 10 and 11, 1978 from a distance of 83 million km 52 million miles or more than half the distance from the Earth to the sun. At this range, Voyager 1 is able to record more detail on the giant planet than the very best ground-based telescopes. The highest re...

Natürlich habe auch ich gestern die (partielle) Sonnenfinsternis beobachtet und fotografiert.
Ihr habt aber heute sicher schon tausende Bilder davon gesehen, daher verschone ich euch mit meinen Fotos.
Dafür gibt es von mir ein Bild aus der letzten Nacht, dem Höhepunkt der Persien. Da habe ich ein paar Sternschnuppen eingefangen, hier besonders schön direkt neben der Milchstrasse.

There's every chance the Gas Giant has moons as well... -
