New Metamaterial Tiles Improve Sensitivity of Telescopes Written by AZoOpticsJan 27 2021 New metamaterial tiles designed by a multi-institutional research team will help enhance the sensitivity of telescopes that are being constructed at the distinguished Simons Observatory in Chile. Researchers developed new metamaterial tiles that will improve the sensitivity of telescopes at the Simons Observatory by absorbing stray light. The top left photo shows one tile, with its anti-reflective surface shown in the insert. The bottom left photos show the back of the tile, and the right photo shows the ...

And is there anything more extreme than peering back on the infancy of the universe? Dr. Nicholas Galitzki has spent much of the past four years at more than 17,000 feet in Atacama, Chile. Highly specialized radio telescopes there have been gathering some of the earliest free-floating photons to have escaped the ultra-dense, opaque pudding that had coalesced some 400,000 years after the big bang — the cold, faint echo of creation first identified about 50 years ago and dubbed the cosmic microwave background. Say what? Don’t worry: Dr. Nick will explain all of that and more at the Ja...

Date Time Metamaterial Tiles Boost Sensitivity of Large Telescopes Low-cost, mass producible technology poised to help Simons Observatory yield new insights into how the universe began WASHINGTON – A multi-institutional group of researchers has developed new metamaterial tiles that will help improve the sensitivity of telescopes being built at the preeminent Simons Observatory in Chile. The tiles have been incorporated into receivers that will be deployed at the observatory by 2022. The Simons Observatory is the center of an ambitious effort to measure the cosmic microwave background – el...

January 12, 2021 New work agrees with older research suggesting the oldest light in the universe – from the most distant galaxy yet known – started its journey toward us 13.77 billion years ago. View larger. | In 2013, the Planck space telescope released the most detailed map to date of the cosmic microwave background, the relic radiation from the Big Bang. It was the mission’s first all-sky picture of the oldest light in our universe, imprinted on the sky when it was just 380,000 years old. Now a new, independent study agrees with Planck’s results. That’s good news for astronomers...

Ideas, Inventions And Innovations New View of Nature’s Oldest Light Suggest Universe Is 13.77 Billion Years Old From an observatory high above Chile’s Atacama Desert, astronomers have taken a new look at the oldest light in the universe. Their observations, plus a bit of cosmic geometry, suggest that the universe is 13.77 billion years old – give or take 40 million years. A Cornell researcher co-authored one of two papers about the findings, which add a fresh twist to an ongoing debate in the astrophysics community. The new estimate, using data gathered at the National Science Founda...
