ESA wraps up 300-million-kilometre optical communication campaign
Over the summer, the European Space Agency ran an optical communication demonstration campaign using two observatories on Earth and NASA’s Psyche mission. All four optical links were successful.

The @vrubinobs.bsky.social has a seismometer inside the pier which is supporting the telescope. Out of curiosity I had a look at the data after the mag 8.8 earthquake that occurred in Kamchatka on July 29th and to my surprise I got the following !

This test of the rotator is an important milestone for the @vrubinobs.bsky.social
We also see that the 3.2 GigaPixel camera is now attached to the piece of hardware (the blueish part at 00:10) that will connect it to the telescope.

Our summit team recently tested the function that the camera rotator is named for and all went well!
The remaining steps to complete before we install the largest camera in the world on our telescope are rapidly shrinking...stay tuned! 👀

Today I needed the coordinates of the Abell 360 galaxy cluster, so for fun, I decided to ask ChatGPT and DeepSeek.
ChatGPT (free version) just said that it doesn't know this cluster !
DeepSeek said that the cluster is in the Volans galaxy (wrong) and gives me totally wrong coordinates.
