We’ve updated and expanded our “Guide to the Electromagnetic Spectrum”! Read on to learn about all the different flavors of light in the Universe, where this light comes from, and how we can detect it.
A new two-layer model of radar scattering seeks to explain the unique properties of various terrains on Saturn’s largest moon.
Over the past couple of decades the Parkes Radio Telescope in Australia has been picking up two types of mysterious signals, each lasting just a few milliseconds. One kind, the Fast Radio Bursts (FRBs), have come from seemingly random points in the sky at unpredictable times, and are thought to have a (thus far unknown) astronomical origin. The other signal, known as perytons, have been found by this paper to have an origin much close to home.
Anti-reflection coatings aren’t just for your glasses — telescope lenses need them too! Here we look at a new technique for reducing reflections in lenses made of silicon.
