Witch's Broom Nebula: The Witch's Broom Nebula is also part of the famous Veil Nebula complex, this being the western portion. The entire complex is the remnant of a powerful supernova explosion which occurred thousands of years ago, sending elements forged in the destroyed stars core into space. The bright star is 52 Cygni.
Star Cluster Pismis 24/Nebula NGC 6357: Pismis 24 hangs over NGC 6357, a nebula about 8000 ly away in the constellation Scorpius. This picture showed that the brightest star in the cluster is in fact two stars in a tight binary orbit. Each star is about 100 times the Sun's mass. Hubble
NGC 6302 (also called the Bug Nebula, Butterfly Nebula, or Caldwell 69) is a bipolar planetary nebula in the constellation Scorpius. The structure in the nebula is among the most complex ever observed in planetary nebulae. The spectrum of NGC 6302 shows that its central star is one of the hottest stars in the galaxy, with a surface temperature in excess of 200,000 K, implying that the star from which it formed must have been very large.
BLUE NEBULA. A nebula from Latin: "cloud"is an interstellar cloud of dust, hydrogen, helium and other ionized gases. Originally, nebula was a name for any diffuse astronomical object, including galaxies beyond the Milky Way.
