IC 1101

IC 1101 Elliptical Galaxy in Virgo

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.

The Elliptical Galaxy's location is 15h 10m 56.1s (R.A.) and +05:44:41 (Dec.). .

The location of the galaxy is sometimes given as being in the constellation of Virgo and some sites have the constellation as being located in the constellation of Serpens.

It gets its name from the being the 1101st item in the Index Catalogue of nebulae and star clusters. It was first discovered by William Herschel, of Uranus fame on 19th June 1790. ref:Wiki

Largest Galaxy in the Universe

IC 1101 is the largest know elliptical or any galaxy type for that matter that we have so far discovered in the Universe. 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 at the centres of most galaxies that are many many trillions time the size and power of stars that orbit it.

Size Comparison of IC 1101 and Milky Way

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).

To give you some idea of how big the galaxy is, our own galaxy has a diameter of about 100,000 light years. Andromeda's Galaxy has a diameter of 210,000 light years across but the IC 1101 has a diameter of about 4 million light years or 2 million light years across for as its radius.

It would take a space ship travelling at the speed of light the same number of years to light years across to cross the galaxy. Therefore it would take 4 Million Years to get from one side of the galaxy to the other.

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

Dying Galaxy

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 untill our galaxy and that galaxy cross paths if ever. 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.
