The first image of #3IAtlas from ESA's JUICE mission is in!

I reprocessed the image to remove hot pixels (left) and the stars (right) to make the tail easier to see.

EDIT: The starless image was updated with a cleaner version.

The same image, but with the stars removed, showing 3I/Atlas in the center, visible as a bright fuzzy object with a faint tail pointing upward.
With no stars in the image, the tail is easier to make out, it appears to be a little undulated.

The ESA Juice (Jupiter Icy Moons Explorer) spacecraft gravity-assist flyby of Venus was successfully executed at 05:28 UTC earlier this morning. No pics are expected.

Juice’s next planetary flybys will be at Earth in Sept 2026 and Jan 2029.

Congratulations to the team.
👏

Flyby success! ESA's Juice spacecraft passed Venus at 07:28 CEST on 31 August.

This photo shows our deep-space antenna in Spain in communication with Juice during the flyby.

Juice’s current location, Venus, and its destination, Jupiter, are both visible in the sky ❤️

Congratulations to the Juice operations team at ESA mission control in Germany for the smooth gravity assist that helped Juice pick up the speed required to get to Jupiter. 👏

Juice’s next planetary flyby will be at Earth in September 2026.

On, on, onwards, up the gravity well!

FYI - during this Venus flyby, Juice is using its steerable medium-gain antenna for communication with earth. The larger high-gain antenna will remain pointed towards the Sun to act as a heat shield.

This also implies that the imaging systems of Juice will not take any pictures during this flyby.
