        Messier 17 (M17) or NGC 6618 also known as the Omega Nebula, Swan Nebula, or Horseshoe Nebula, is a bright emission nebula located in the constellation Sagittarius. It lies about 5,000–6,000 light-years from Earth in the Milky Way and is part of a large star-forming region. The nebula spans approximately 15 light-years across and is rich in hydrogen gas, which gives it its characteristic red-pink glow due to ionization from nearby young, massive stars.

        I understand the size of a nano meter (1*10e-9 meters) but have a hard time phantom a billion light years (9*10e+24 meter).
