The Atacama Large Aperture Submillimeter Telescope (AtLAST) is a concept for a 50m class single-dish telescope that will provide high sensitivity, fast mapping of the (sub-)millimeter sky. Expected to ...

The Simons Observatory (SO), a most advanced network of telescopes aimed at mapping the Cosmic Microwave Background (CMB) with unprecedented precision, has reached a major milestone: the Large ...

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 ...

Robert Zubrin has proposed using rotating membranes to create Enormous Space Telescopes (ESTs) that can scale to over 1000 meter diameter or match current space telescopes for thousands of time lower ...

For nearly as long as we've walked the Earth, humans have tried to make sense of the stars. Now, three new sky-gazing tools are poised to tell us even more. Each will play a unique role in deciphering ...

An extremely large telescope (ELT) is a class of telescope with an aperture of more than 20 m diameter when discussing reflecting telescopes of optical wavelengths including UV, Visible, and Near ...

One hundred years ago, the largest telescope in the world was the historic 100-inch-diameter (2.5 meter) John D. Hooker reflecting telescope at Mt. Wilson Observatory, just north of the greater Los ...
