IC 1101 is the largest galaxy ever discovered in our universe of 100 billion galaxies. IC 1101 is one of hundreds of galaxies in the galaxy cluster ABEL 2029, about 100 million light-years away.
The idea of a galaxy was first proposed by the scientist Thomas Wright in 1750, but no one accepted his idea, as Galileo had been imprisoned for claiming that the earth was round.
IC 1101 was discovered in 1790 by the British astronomer Frederick William Herschel.
At 100 million light-years from Earth, the galaxy has a diameter of 60 million light-years. Our Milky Way is about 1 million light-years in diameter, or 60 Milky Ways. In terms of distance, light traveling at 3 million kilometers per second would take 60 million years to reach from one end to the other.
It is estimated that the galaxy formed about 12 billion years ago. Probably because it swallowed up many other galaxies that day, IC 1101 became such a huge galaxy that it contains about 100 trillion stars and planets.
Anyway IC 1101 is becoming inactive. There are no interstellar materials or nebulae needed to form new stars. If other galaxies were to be swallowed up in the future, the galaxy would probably be active if it received the energy, dust, and other matter needed to form stars.
It is not yet clear whether IC 1101 is a lenticular galaxy or an elliptical galaxy. However, based on the information obtained, it has been determined to be an elliptical galaxy. More than half of the light emitted from the galaxy comes from a supermassive black hole’s outer disk aggregation disk about two light years from the center.
This black hole is about 2,000 astronomical units in diameter. That’s about 50 times the distance from our Sun to Pluto. We have yet to build a system or telescope for direct observation and confirmation. The size of the central black hole is about the size of a normal galaxy. If so, you can guess the size of IC 1101’s super massive black hole
