Green Cosmic Blob and Gas Bubble Tells Story of Supermassive Black Hole
In space, most bodies are linked to each other and understanding the behavior and attitude of one can lead to the further knowledge about the universe. Good examples are the green cosmic blob and a gas bubble that are helping researchers and scientists understand the history of a supermassive black hole. Experts believe that this methodology can pave the way for a more in-depth probe about the changes and evolution of supermassive black holes.
In 2003, Hanny van Arkel discovered the Green Blob also known as the "Hanny's Voorwerp" or "Hanny's Object" named after its discoverer. The Green blob is located about 200,000 light-years away from Earth populating the galaxy IC 2497. The object owes its green glow to the radiation emitted by a nearby black hole; the radiation exited the oxygen atom resulting in the mystifying green glow. However, the black hole in IC 2497 is still expanding moderately and not as powerful to turn the whole blob green, according to Space Daily.
In the research and study conduct by experts and will also soon be published in the journal Monthly Notices of the Royal Astronomical Society, it is stated that the blobs green glow reflects the behavior of its neighboring black hole.
Although far enough, the Green blob may offer a glimpse of the nearby black hole's past. If proven true, the black hole may provide evidence on how the black hole began its life as a quasar, one of the biggest black holes in te universe. But based on the observations, the green blob has been a quieter and slower promoting scientist to say that it may soon appear less bright as it is today.
The Green blob also has a hole in the middle composed of a hot gas bubble that is considered a cooler gas.
