IC 1340 is the eastern segment of the Veil Nebula, itself also called the Cygnus Loop. It is the result of a supernova explosion visible from Earth about 10,000 years ago. It is about 1,400 light years away from Earth. IC 1340 is about 12 light-years across.
IC 443 is a supernova remnant known as the Jellyfish Nebula. It is found in the constellation Gemini about 5,000 light years from Earth. The supernova blast itself brightened the night sky about 30,000 years ago. The star to the right of the Jellyfish is Eta Geminorum.
Between the constellations Libra & Serpens is the globular star cluster M5, packing 100,000 stars or more, bound by gravity, into a region about 165 light-years in diameter. It lies some 25,000 light-years away from planet Earth. The stars in M5 are some of the oldest in the Milky Way, some 13 billion years old.
Globular star cluster Messier 9 (M9) has over 300,000 stars within a diameter of about 90 light-years. It is 25,000 light-years from Earth, near the central bulge of our Milky Way galaxy in the constellation of Sagittarius. Imagine the night sky on a planet orbiting one of these stars!
NGC 7635 is known simply as The Bubble Nebula, a 10 light-year diameter bubble blown by intense stellar winds from the O-class star above and right of the Bubble's center. That star is several hundred thousand times more luminous and around 45 times more massive than Earth's sun. The Bubble Nebula is 11,000 light-years away toward the constellation Cassiopeia.
Wispy tendrils of hot dust and gas glow brightly in this ultraviolet image of the Cygnus Loop nebula, taken by NASA’s Galaxy Evolution Explorer. The nebula lies about 1,500 light-years away, and is a supernova remnant, left over from a massive stellar explosion that occurred between 5,000 to 8,000 years ago.
