IC 443 (also known as the Jellyfish Nebula and Sharpless 248 ) is a galactic supernova remnant (SNR) in the constellation Gemini. On the plane of the sky, it is located near the star Eta Geminorum . Its distance is roughly 5,000 light years from Earth.
It was likely formed 30,000 years ago in the supernova that created the supernova remnant IC 443, the "Jellyfish Nebula." [ 2 ] [ 3 ] [ 4 ] It is travelling at approximately 800,000 km/h away from the site.
Messier 30 (also known as M30, NGC 7099, or the Jellyfish Cluster) is a globular cluster of stars in the southeast of the southern constellation of Capricornus, at about the declination of the Sun when the latter is at December solstice.
A jellyfish galaxy is a type of galaxy found in galaxy clusters. They are characterised by ram pressure stripping of gas from the affected galaxy by the intracluster medium , triggering starbursts along a tail of gas.
The mean expansion velocity of the nebula seems to be slow at 20 km/s at the outer layer, [7] while it also reaches a maximum expansion velocity of 60 km/s relative to its central star. [8] Its central star has a magnitude of around 14m [7] and a temperature of around 47,000--59 000 K. [9] The most characteristic feature of IC 4997 is its ...

NGC 3324 is an open cluster in the southern constellation Carina, located northwest of the Carina Nebula (NGC 3372) [3] [4] at a distance of 9,100 ly (2,800 pc) from Earth. [2] It is closely associated with the emission nebula IC 2599 , also known as Gum 31 . [ 5 ]
NGC 2174 (also known as Monkey Head Nebula) is an H II [1] emission nebula located in the constellation Orion and is associated with the open star cluster NGC 2175. [1] It was discovered on 6 February 1877 by French astronomer Édouard Stephan. [2] It is thought to be located about 6,400 light-years away from Earth.
