Hubble only took the most detailed picture of the eerie and mysterious Ghost Nebula.
Some 550 light years from our humble little planet live IC 63 – Ghost Nebula. The nebulary is found in the constellation Cassiopeia, because it is classified as both a reflection nebula and an emission bubble. It reflects the light of its giant neighbor, the star Gamma Cassiopeiaea – and it also releases hydrogen-algae radiation.
Named after the Greek mythology’s vanity queen, Cassiopeia was known as Cassiopeia’s Chair. In the 1930s, the International Astronomical Union gave this constellation the official name Cassiopeia Queen. Cassiopeiae forms an “easy-to-see, extended” W “shape in the sky, with the central point of W holding the magnificent Gamma Cassiopeiae.
Gamma Cassiopeiae is seriously a superstar among the stars ̵
1; a blue-white subgiant surrounded by a According to the European Space Agency (ESA), the star is 19 times more massive and 65,000 times brighter than our Sun. “It also rotates at an incredible speed of 1.6 million kilometers per hour – more than 200 times faster than our parent star, “notes ESA.” This frantic rotation gives it a cluttered look. The rapid rotation causes outbreaks of mass from the star to an surrounding disc. This mass loss is related to the observed lightness variations. “Drama much?
As for our little Ghost Nebula, its hydrogen is bombarded by ultraviolet radiation from Gamma Cassiopeiae, which causes its electrons to get energy that they later release as hydrogen alfa radiation, explains ESA. These emissions stand for the red in the picture, the blue is light from Gamma Cassiopeiae, which is reflected by dust particles in the nebula. Is she not extraordinary?
The image above was taken from above Earth’s atmosphere of the Hubble space telescope – probably the most detailed picture ever taken of IC 63.
While this wonderful nebula ultimately spreads thanks to ultraviolet radiation from Gamma Cassiopeiae, there is still a lot of other activity going on (well at least 550 years ago) in the much larger nebulous region around Gamma Cassiopeiae.
“This region is best seen from the northern hemisphere during a fall and winter,” ESA writes. “Although it is high in the sky and sight it’s very dim, so observe it requires a rather big telescope and darken the sky. “
Or you can just watch this video, starting here at home with the night sky and flying you through space, right wing in the middle of Cassiopeia’s ghost. The world is really a wonder …
