Little Telescope Spies Gigantic Galaxy Clusters

  • Categoría Astronomía
  • Our solar system, with its colorful collection of planets, asteroids and comets, is a fleck in the grander cosmos. Hundreds of billions of solar systems are thought to reside in our Milky Way galaxy, which is itself just a drop in a sea of galaxies.

    The rarest and largest of galaxy groupings, called galaxy clusters, can be the hardest to find. That's where NASA's Wide-field Infrared Survey Explorer (WISE) can help. The mission's all-sky infrared maps have revealed one distant galaxy cluster and are expected to uncover thousands more.
