'The Green Blob', it's different to see a space object known as a name rather than a number or something like that, although I am sure it has been issued a number correspoding with the name of the person who discovered it.
I have come across a picture as well of 'The Green Blob' with a little snippet of info and the link:
"The collection of gases is roughly the size of our Milky Way galaxy and its bright green colour comes from oxygen".
