Hello, Everyone!
An enigmatic nebula called the Gum Nebula has been spotted with an intriguing object referred to as God's hand elongated in the cosmos.
In this blog post, we will delve into the insights of the Gum Nebula and the fascinating features of the Gum Nebula-CG4{Cometary Globule 4}. So let's get started.
THE GUM NEBULA:
The Gum Nebula (Gum 12) is a massive emission nebula-glowing cloud of dust and hydrogen gas spotted in the sky, extending 36 degrees in the Vela and Puppis constellations. The Gum Nebula is a very mild radiating nebula to be observed with the naked eye. The Gum Nebula is approximately 1000 light years distant from our Earth, with its furthest point being 1500 light years from Earth. According to astronomers, the Gum Nebula is a remnant of the supernova explosion and not the hydrogen cloud -called the HII region
VELA CONSTELLATION:
The Vela constellation is observed in the southern hemisphere within the latitudinal range of +30 degrees and -90 degrees.
The Vela constellation has been named after the ship called Argo Navis. A renowned France-based astronomer -Nicolas Louis has bifurcated the Vela constellation into three constellations-Vela(the sails),Carina-(the keel), and the Puppis -(the stern) which was earlier believed to be a part of a bigger constellation Argo Navis.
The Vela constellation consists of comic entities such as the Gum Nebula,Ring Nebula(NGC 3132), and Vela Supernova remnant-which is believed to be a remnant of the collapsed star that was once in the same location as the remnant. and many more cosmic entities.
COMETARY GLOBULE 4:
A cometary globule 4-CG4 has been situated in the Gum Nebula appearing like a hand elongated in the cosmos.
A cometary globule is a faded dust and gas cloud which are smaller in size and appears like a comet with the heads having a head and a tail similar to the comet.
CG4 is a site where stars originate and the dimensions with the heads- having a diameter of 1.5 Light Years and a tail -extending to 8 light years. The head is much denser and is light-blocking and glows due to the star in proximity to it.
The Cometary globule 4 is a dark nebula that consists of hydrogen clouds along with helium and other elements too that block light passing through it, that's why they seem dark. The tail is pointing away from the source of radiation e.g. a heated colossal star or a supernova remnant. It is believed that the shape of CG4 might be due to a supernova explosion which has extended a spherical nebula to a comet-looking shape. Another belief is that the radiation pressure emerging from the nearby stars might have exerted the dust and gas in the CG4, thereby extending its tail.
Conclusively, CG4 is an intriguing cosmic entity featuring mind-blowing properties of cometary globules, a sort of dark nebula that has a unique shape and plays a pivotal role in stellar birth.
In essence, CG4 showcases the fascinating properties of cometary globules, a type of dark nebula known for their unique shape and role in stellar birth.
