The sub-mm sky is a unique window for probing the architecture of the Universe and structures within it. From the discovery of dusty sub-mm galaxies, to the ringed nature of protostellar disks, our ...

As the largest optical telescope in the world, the ELT will allow scientists to dive further into our universe than ever before. The ELT’s 39-metre ‘eye on the sky’ will capture some of the clearest ...

One of the biggest questions humanity ever dared ask is "are we alone?" Decades (perhaps centuries) after it was first asked, and despite the incredible advancements our species has made with space ...

The Large Aperture Telescope optical system they characterized is now on its way to Chile for installation. The Simons Observatory will include the Large Aperture Telescope as well as three Small ...
