239 years ago, William Herschel discovered Oberon & Titania, the largest Uranian moons. All but a few of Uranus' moons are named after characters from Shakespearean plays. Oberon and Titania pay homage to the fairy king and queen in "A Midsummer Night's Dream"

On 7 January 1610, Galileo Galilei discovered three of Jupiter's four largest moons, known as Galilean moons (named Io, Europa, Ganymede and Callisto by the German astronomer Simon Marius in 1614).

Open up this picture fully.

Then look at the surface of Mars.

Then look up to the top right.

Spot Mars' moon Phobos high in the sky.

Then notice the bright spot beside Phobos.

That's Earth.

Superb video included in today's JPL update for #PerseveranceRover (www.jpl.nasa.gov/news/nasas-p...). With synthetic frames and obviously, the rover doesn't move that fast, but the final result is impressive.

This is an incredible image of comet 3I/ATLAS, taken by Satoru Murata ICQ Comet Observations group on 16 November 2025 from western New Mexico.

Structure within the major dust tail from the comet is clearly visible, together with two smaller jets trailing the nucleus and maybe even an anti-tail.

Plus sérieusement, si vous ne voyez pas le problème avec Twitter, vous faites partie du problème.
Grok n'est pas une source d'information. Que faut-il de plus – après une semaine de désinformation par Grok concernant les attentats du 13 novembre – voyez ce cas gravissime de #négationnisme et d' #antisémitisme.

En France, c'est un délit. Pourquoi puis-je voir ce post alors ?

Here’s an annotated version of our comet image.

We also want to thank our downlink and uplink teams who spent a huge amount of time working on this. Our camera was not designed to image interstellar objects 19 million miles away, but their hard work and planning paid off.
