IC 1101 is an elliptical galaxy object of interest in space. It lies at a distance of 1.04 Billion light years away in the constellation of Virgo. It is also referred to as IC1101 which is short for Index Catalogue number 1101. The Index Catalogue is an update to the earlier NGC catalogue. IC 1101 was discovered in 1790 by William Herschel. The Elliptical Galaxy's location is 15h 10m 56.1s (R.A.) and +05:44:41 (Dec.). .
The IC 1101 galaxy is the largest elliptical or any type galaxy for that matter to have yet discovered. It is classed as a dying galaxy as it doesn't have many new stars being born unlike our own galaxy, the milky way. Some stars are being born but at a very slow rate. Our own galaxy continues to produce new stars, not at the same rate as which it once did but it continues to do so unlike IC 1101. The only way this galaxy will survive is to consume other galaxies like it has done in its past. Just because the galaxy is a dead galaxy, it doesn't mean that there aren't alien life forms in that part of the universe, its just refers to the birth rate of new stars. The galaxy grows by cannibalising smaller galaxies that get too close to it. It is so far away, you will not be able to see it without using an observational aid. It will be a long long time till when our galaxy and their galaxy paths meet. Before the collision of our galaxies occur, we'll have merged with other galaxies such as Andromeda's which that won't be for another five billion years. The video at Hubble Site has a brief video about galaxies and how its grown over the years with scale.
We know its a dying galaxy by the colour that the galaxy gives off. A blue coloured galaxy is one that is full of activity of young stars but a yellowy galaxy such as IC 1101 is docile, dying. IC1101 is an elliptical galaxy which older galaxies tend to be whereas our galaxy is believed to be a spiral galaxy. Its believed to be so because its been calculated as being an spiral galaxy, no one has ever and will probably ever see it.
Our galaxy is estimated to have about 200-400 billion stars (400,000,000,000) which might seem a lot but then IC 1101 has an estimate 100 trillion stars (100,000,000,000,000).
In addition to it being the largest galaxy, it also has the largest supermassive black hole in any galaxy so far spotted. Supermassive black holes are the centres of galaxies that are many many trillions time the size and power of stars that orbit it.
To give you some idea of how big the galaxy is, our own galaxy is a mere 100,000 light years across. Andromeda is 210,000 light years across but the IC 1101 is about 2 million light years from its core to the outside edge. If the IC1101 was in the same position our galaxy was in, it would not only consume the Milky Way but it would also consume the Triangulum galaxy, Magellanic clouds, both Large and Small and also the Andromeda Galaxy . ref:futurism
