NASA JPL “GAMMA RAY GHOULS” EXOPLANET EXPLORATION SPACE PATCH- 3.5”:
With Halloween just around the corner, NASA has released its latest Galaxy of Horrors posters. Presented in the style of vintage horror movie advertisements, the new posters feature a dead galaxy, an explosive gamma ray burst caused by colliding stellar corpses, and ever-elusive dark matter.
As fun and creative as all three posters are, they're based on real phenomena. In a dead galaxy, new star birth has ceased and most remaining stars are the long-lived variety, which are small and red, giving the galaxy a crimson glow. Likewise, when dead stars collide, they sometimes create a gamma ray burst, one of the most energetic explosions in the universe. And while dark matter may sound like it's right out of a Halloween tale, its gravity keeps stars inside galaxies and holds groups of galaxies together in clusters – yet scientists don't know what this invisible stuff is made - JPL NASA Patch. Condition is New. Shipped with USPS.
