A galactic nuclei or supermassive black hole has seen its light emission decrease.
AGNs or Active Galactic Nuclei are supermassive black holes that emit vast amounts of energy. One, in particular, has seen a dramatic transformation to the amount of light it emits over that past 30 years. Mrk1018 is the name given to this particular super massive black hole which has the mass of approximately 100 million suns.
The black hole is surrounded by a ring of gas that it gorges on to feed its enormous appetite. As a result, the gas that is consumed emits a bright light when the energy is transformed.

In an article, published by the Institute of Astrophysicist in Andalusia, Mrk1018: the black hole that returns to the shadows (IAA, 2016) it has been disclosed that the Hubble Telescope (NASA) and the Chandra Telescope (NASA) have been observing these changes to the galactic nuclei.
Perez Torres from the IAA has advised that the observations have suggested that the black hole’s appetite or access to food, in the form of gas, has recently decreased. This means that it previously consumed five hundredths of a solar mass worth of gas per year, but is now only consuming five thousandths of a solar mass of gas in one year – lessening the light emissions coming from the black hole.
It has been posited by Torres and the IAA that this shortage of gas could be due to the interaction with a second supermassive black hole within the vicinity. Plans are in place to continue to observe the material surrounding Mrk1018 to identify changes in light emissions coming from this gigantic galactic nuclei.
