140 Million Suns! Monster Black Hole Weighs In
A heavyweight black hole in the heart of a distant galaxy has the mass of 140 million suns, according to new measurements. A vivid video by the National Radio Astronomy Observatory describes how researchers "weighed" the black hole at the center of the barred spiral galaxy NGC 1097.
Many galaxies have huge black holes in their centers, and these objects affect the galaxies' growth and evolution. The galaxy NGC 1097 is 47 million light-years away from Earth, too far to determine the mass of its central black hole by the movement of the stars around it. But by tracking the movements of two types of molecular gases around the galaxy's center, researchers using the Atacama Large Millimeter/submillimeter Array in Chile (ALMA) were able to work
backward and figure out the black hole's gravitational pull.
The black hole at the center of this galaxy, NGC 1097, is the mass of 140 million suns. The banded galaxy is 47 million light years from Earth, and this photo comes from optical measurements by the Very Large Telescope.

The gases don't interact strongly with environmental conditions within the galaxy, such as ionized gas flowing inward or outward. This means the gases paint an accurate picture of the effects of gravity's pull alone. With just two hours of observational data

Onishi (SOKENDAI), NASA/ESA Hubble Space TelescopeThe mass of a central black hole affects the physical properties of its host galaxy, and recent work has shown that those effects are different for different types of galaxies , study lead author, Kyoko Onishi, a doctoral student at the SOKENDAI (The Graduate University for Advanced Studies) in Japan, said in a statement . To understand those effects, Onishi said it's important to measure the mass of these central black holes in various galaxy types.
Because of the quick precision measurements, "ALMA will enable us to observe a large number of galaxies in a practical length of time," added Onishi, who is doing her research

Now that is a black hole!
140 million suns is a lot of energy!
There is a video at the link for your viewing pleasure
Amazing photos and video RIO...140 million suns, it's darn near impossible to wrap your head around that.

That was exactly the conclusion I cam to as well.
I love space exploration stories and pictures/
