Thanks to an epic effort by the Chile site team and by students and staff at JHU and Villanova, we have repaired our modulator and recovered from a brief down time! https://t.co/4218zTfylL

Beautiful new reflective half-wave plate being made here. The copper sheen is about a kilometer's worth of 100 µm wire. Though admittedly with the handles and the color it looks like paella 🥘!

🚀 Science Fair day in San Pedro de Atacama, the main local community close to the telescopes 🇨🇱🫶 The CLASS site team Deniz and Jullianna created and hosted an interactive display about the telescopes and cosmology for students and other residents! 💫

We have achieved 🌟 First Light 🌟 with the second CLASS 90 GHz telescope. 🤩 The detector performance is looking good. A few things to clean up 🧹 before cosmological observations, but we are almost there!

Johns Hopkins researchers are part of an international team that has installed a new dark matter detector about two kilometers beneath the French Alps. The technology is designed to search for lighter dark matter particles that previous experiments could not detect.

Not a bad commute! A view from the drive home from the observing site.

🐝🐝🐝 The CLASS site team has been busy! 🐝🐝🐝 Here is a video of them assembling the new receiver, which comes together as nested layers. When operating, all layers are under vacuum, and outer layers thermally shield colder layers underneath. The innermost is at 0.05 Kelvin!
