Astronomers have discovered OSCILLATION in the Orion Arm of the Milky Way Galaxy that spans 9000 LIGHT YEARS LONG!!! Plus, 3 newly discovered moons have been designated mythological names, and a new source for cosmic rays has been detected by one of the most HI-TECH OBSERVATORIES IN THE WORLD!!!

Previews to today's articles:

#1: "Astronomers are still discovering strange things in space, and the latest is something they’ve named the Radcliffe Wave. This wave-shaped chain of star-forming clouds is the largest coherent structure ever seen in our galaxy — 9,000 light-years from end to end, stretching across the night sky from Canis Major to Cygnus, with Orion in between. Now it turns out the Radcliffe Wave is actually waving" (Joel Achenbach, The Washington Post).

#2: "The solar system just got three new official residents — a trio of tiny moons, one of which orbits Uranus and two more that circle Neptune. The three moons were all spotted several years ago but were recently confirmed by the International Astronomical Union's (IAU) Minor Planet Center[...]" (Harry Baker, Live Science).

#3: "In a recent study, members of China’s Large High Altitude Air Shower Observatory (LHAASO) Collaboration discovered a massive gamma-ray burst (designated GRB 221009A) in the Cygnus star-forming region that was more powerful than 10 peta-electronvolts (PeV, 1PeV=1015eV), over ten times the average. In addition to being the brightest GRB studied to date, the team was able to precisely measure the energy spectrum of the burst, making this the first time astronomers have traced cosmic rays with this energy level back to their source." (Matt Williams, Universe Today).
