Large, all-glass metalens images sun, moon and nebulae
Metalenses have been used to image microscopic features of tissue and resolve details smaller than a wavelength of light. Now they are going bigger......»»
Computer modeling research reveals the changing history of a global ice sheet
Imagine that a massive ice sheet covered Canada and oozed down over a large part of the northern United States, like icing spilling down the side of a cake. That was the situation somewhere between 19,000 and 26,000 years ago. The ice sheet covered l.....»»
Observations detect hundreds of possible supergiant stars in two nearby galaxies
Using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Chinese astronomers have identified nearly 300 candidate supergiant stars in the Andromeda and Triangulum galaxies. The finding was reported in a research paper published O.....»»
