The European Space Agency’s latest astrophysics mission, Euclid, lifted off on a Space X Falcon 9 from Cape Canaveral in Florida, USA, at 17:12 CEST on 1 July 2023. Euclid has now started its month-long journey to Sun-Earth Lagrange point L2, located 1.5 million kilometers from Earth, in the opposite direction from the Sun.

The Devlin lab are working on creating an extremely cold environment (nearly -460 degrees Fahrenheit) so that the new Simons Observatory can detect cosmic microwave background (CMB), the residual radiation left behind by the Big Bang. Work done at the High Bay is essential for keeping the project from falling further behind after shutdown delays.

Where did the cosmos come from? This question has long been part of human speculation, says Vijay Balasubramanian. Today, thanks to scientists like Ralph Alpher and George Gamow, we have a rough picture: Some 13 billion years ago, the universe was a hot, dense state that cooled as it expanded.

A view inside the SNO detector when filled with water. In the background, there are 9,000 photomultiplier tubes that detect photons and the acrylic vessel that (now) holds liquid scintillator. The ropes that crisscross on the outside hold it down when the scintillator is added to prevent it from floating upwards. The acrylic vessel is 12 m wide, about half the width of an Olympic-sized swimming pool. The detector is located in SNOLAB, a research facility located 2km underground near Sudbury, Canada.
