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.
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!
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.
The first astronomical object cataloged by Charles Messier, M1 is perhaps better known as the Crab Nebula. It's a supernova remnant; its massive explosion visible to skygazers in the year 1054. At its center is a rapidly rotating pulsar - a neutron star - located about 6,500 light-years from Earth in the constellation Taurus.
Death Star: Eta Carinae, one of the closest stars to Earth is huge and unstable and will likely explode in a supernova in the relatively 'near future' (On an astronomical timeline this could be a million years from now). via NASA #Eta_Carinae #Supernova #NASA
Massive star IRS 4 is beginning to spread its wings. Born about 100,000 years ago, material streaming out from this newborn star has formed the nebula dubbed Sharpless 2-106 Nebula (S106), pictured above. It lies about 2000 light-years away toward the constellation of the Swan (Cygnus).
