Black holes, supernovae, neutron stars, pulsars, oh gee,… radio beasts in a gravitational sea … Radio telescopes have been the workhorses of cosmic sky surveys for a long time. Yet, often eclipsed in public media by the Hubble and Webb space telescopes (using visible and infrared light waves). But radio wave imaging will get more… Continue reading Cosmic ‘bumps in the night’ – DSA advances radio astronomy
Epic events catch our attention. Spectacular stellar events have attracted attention since ancient times. Some events, however, cannot be observed with our eyes (visible light). Radio sources. And massive spikes in radio energy are telling astronomers something interesting. • NASA > “Hubble Tracks Down Fast Radio Bursts to Galaxies’ Spiral Arms” (May 20,2021) [Includes YouTube… Continue reading FRBs – whence galactic epic flashes of energy?
So, it’s that time of year again: lots of recaps, lists of top this-and-that. Even milestones, discoveries, or breakthroughs in science. Here’s a YouTube video highlighting some progress in physics: • YouTube > Quanta Magazine > “The Year’s Biggest Breakthroughs in Physics” (Dec 23, 2020) YouTube description: This year, two teams of physicists made profound… Continue reading 2020 highlights
