The Biggest Blackhole in our Universe

--------- #1330 - What is the Biggest Blackhole?

- Attachment: M87 Galaxy

- Our Milky Way Galaxy is one of 5,000 galaxies located in the Virgo Cluster of galaxies. The Virgo Cluster is 53,500,000 lightyears away and at the center of this cluster of galaxies is a massive galaxy called M87. M87 is the largest galaxy in the Virgo Cluster and it has the biggest Blackhole astronomers have found to date.

- Rather than a spiral galaxy of stars M87 is a sphere of stars, up to several trillion stars. Our Milky Way has 1/10^th that number of stars. Adding Dark Matter to his mass of stars makes M87 200 times the mass of our galaxy.

- The Blackhole at M87’s center is 6,000,0000,000 Solar Mass and has a diameter that is about the same as the orbit of Pluto. The Blackhole at the center of our galaxy is 4,000,000 Solar Mass. There are enormous Gamma Ray jets coming from M87’s Blackhole. The jets are deep blue in color that is caused by synchrotron radiation. The visible jets are 5,000 lightyears long and are produced by the strong electromagnetic forces created by matter swirling around the gravity drain of the Blackhole. These forces pull gas and magnetic fields away from the rotating body at its poles. The jets are narrow beams that contain shockwaves. These shockwaves create high energy electrons that spiral around the magnetic field lines. Approaching the speed of light the electrons radiate synchrotron radiation.

- There are also loops and bubbles in the hot, X-ray emitting gas that are the relics of small outbursts coming from the Blackhole. There are also narrow filaments of X-ray emission that are due to hot gas that is trapped by magnetic field lines. One of the filaments extends over 100,000 lightyears and beams in almost a straight line.

- M87 presents quite a picture. Our galaxy’s Blackhole is quiet. There is evidence that it may have been that active in the distant past. See review #1321 Milky Way Gamma Ray Bubbles to learn more about this theory. To see M87 use a backyard telescope aimed at the Constellation Coma Berenices. The Magnitude is 9.59 It is only 53 million light years away. There is little chance you will fall in the biggest Blackhole in our Observable Universe.
