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?
Who would have expected the Hubble Space Telescope (often referred to as HST or Hubble) to still be in operation after being launched into low Earth orbit in 1990? So, NASA/ESA kickstarted its 30th anniversary with some majestic galactic photos.
