What is the largest galaxy ever discovered?
Alcyoneus
A newly discovered radio feature originating from the same galaxy has been measured to span an unprecedented 16 million light-years across, making Alcyoneus the largest known galaxy of all.
Is there a galaxy bigger than IC 1101?
At 16.3 million light-years wide, the Alcyoneus galaxy has a diameter 160 times wider than the Milky Way and four times that of the previous title holder, IC 1101, which spans 3.9 million light-years, researchers reported in a new study.
How big is IC 1101 compared to Milky Way?
IC 1101 spans 4 million light years – some estimates even give the galaxy a diameter of 6 million light years – while the Milky Way has a visible diameter of 150,000 to 200,000 light years.
How many times IC 1101 is bigger than the Milky Way?
The galaxy, which is named Alcyoneus, after the son of the primordial Greek god of the sky, Ouranos, is four times the size of IC 1101 and spans across 16.3 million light-years. A galaxy, a whopping 160 times the size of the Milky Way galaxy, has been found and tagged as the largest galaxy ever discovered.

How old is TON 618?
10.8 billion years old
As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc. The light originating from the quasar is estimated to be 10.8 billion years old.
Is IC 1101 visible from Earth?
Its Visual (Apparent) Brightness is 13.22 Magnitude. Anything with a magnitude of less than 6.5 can be seen with visual aids. The lower the number, the brighter the object is to see. The object can not be seen by the naked eye from Earth, you need a telescope to see it.
Is TON 618 a quasar or a black hole?
How big is the UY Scuti star?
738.35 million miUY Scuti / Radius
How big is our black hole?
about 23.6 billion miles
The gigantic black hole, not counting the giant rings of trapped light orbiting it, is about 23.6 billion miles (38 billion kilometers) across, according to Science News. Meanwhile, the Earth is just 7,917 miles in diameter — meaning our planet wouldn’t even be a drop in the bucket of the giant, black void.
What type of galaxy is IC 1101?
From Wikipedia, the free encyclopedia IC 1101 is a supergiant elliptical galaxy at the center of the Abell 2029 galaxy cluster and is one of the largest known galaxies. Its halo extends about 600 kiloparsecs (2 million light-years) from its core, and it has a total of about 100 trillion stars.
What is the biggest galaxy in the universe?
The Biggest of the Big. This brings us to the main point of this article – IC 1101. Located almost a billion light-years away, IC 1101 is the single largest galaxy that has ever been found in the observable universe.
How many stars are there in IC 1101?
For comparison, the Milky Way is believed to contain a mere 100 billion stars (that’s a lot, but not compared to a trillion). This brings us to the main point of this article – IC 1101. Located almost a billion light-years away, IC 1101 is the single largest galaxy that has ever been found in the observable universe.
Is IC 1101 the largest known supermassive black hole?
IC 1101 and other ellipticals contain at its center, a supermassive black hole. It is commonly understood that the mass of a galaxy’s central black hole is tightly linked to the size of the galaxy, making the one at the center of IC 1101 the largest known supermassive black hole. This galaxy is dying a slow death.
