The Waterfall Nebula – also called HH-222 – is located approximately 1,500 light years away from Earth in the Orion Molecular Cloud. The process of it’s formation remains a mystery. One theory is that the nebula is the result of stellar winds blowing from a young star which is hidden nearby.
2) The Necklace Nebula
This is a planetary nebula which is located 15,000 light-years away in the northern constellation Sagitta. The nebula is over 12-trillion-mile-wide! It is believed that it was created when a giant star crashed into it’s close companion binary star.
3) V838 Monoceros
V838 Monoceros is located 20,000 light years away from Earth in the constellation Monoceros. It is approximately 13.7 light years in width. In January 2002 for a short time it’s brightness increased by an incredible 4,000 times and it became the brightest star in the Milky Way!
4) The Hand of God
Otherwise known as PSR B1509-58, this is a pulsar which is located 17,000 light years away in the constellation of Circinus. The pulsar was created when a star exploded here approximately 18,7000 years ago! This pulsar is estimated to have a spin rate of 7 times per second!
