Tycho's supernova remnant seem to suddenly appear in the sky's around 1572. The remnant is found in the constellation of Cassiopeia, 9,000 light years away from earth and is no longer visible to the naked eye. Tycho was born as a white dwarf star but later in its life became tied up in a binary system with another star. When both stars came close enough to one another, Tycho began to draw out all of the Hydrogen from the companion star, brightening and increasing in size . Tycho had accreted so much matter from its companion star that the white dwarf reached its maximum mass and literally exploded. The supernova remnant is named after the Danish astronomer Tycho Brahe due to his work and observations of the star. His extensive work was said to help astronomers gain a deeper understanding to our Universe , helping to speed up a new revolution of astronomy.
The Calabash Nebula, Also known as the Rotten Egg Nebula found in the constellation of Puppis 5,000 light years away from earth. The Nebula is around 1.5 light years is the aftermath of a dying star. The shape of the nebula is formed due the the dying star releasing violent gas eruptions and supersonic shock waves. The Calabash Nebula gets its name "The Rotten Egg" due to the nebula containing very high amounts of sulfur gas. Ionized Hydrogen and Nitrogen gases can be seen in the image above shown by the bright yellow / orange colours whilst the shock waves giving off by the star can be seen in blue.
IC2118, Also known as The Witch Head Nebula due to the nebula's particular appearance. IC 2118 is found in the constellation of Eridanus, roughly about 900 light years away from Earth. The nebula is said to be the remains of a supernova remnant which is simply the result of a exploding star. The gas cloud is thought to be the home to thousands of newly forming stars whilst old, ancient stars have been found lurking deep within the nebula. IC 2118 sits nearby a bright star named Rigel which can clearly be seen in the image above and can be found in the constellation of Orion. Rigel of Orion is one of the more easier stars to spot in the night sky and is said to be one of the brightest stars visible to the naked eye. The super-giant blue star illuminates IC 2118, 40 light years away shining 40,000 times brighter than our sun. The clouds of interstellar dust particles which make up the nebula are mostly made up of carbon compounds which are slightly polarized by light reflected from Rigel, which in turn causes the nebula to glow blue.
