What are some examples of elliptical galaxies?
Examples. M87 (NGC 4486), whose supermassive black hole is the first black hole to be imaged by the Event Horizon Telescope. IC 1101, one of the largest galaxies in the observable universe. Maffei 1, the closest giant elliptical galaxy.
What is the largest elliptical galaxy?
IC 1101 is a supergiant elliptical galaxy at the center of the Abell 2029 galaxy cluster and is one of the largest known galaxies….

|Apparent magnitude (V)||14.73|
What is in an elliptical galaxy?
Elliptical galaxies are made up of mostly old stars, and do not have much gas and dust. There is very little new star formation in these galaxies. Elliptical galaxies also come in many sizes. The largest galaxies we see are ellipticals, but, elliptical galaxies can also be small.
What is the closest elliptical galaxy?
Sagittarius Dwarf Elliptical Galaxy
The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
What are 3 facts about elliptical galaxies?
Elliptical galaxies have a large range of sizes. The largest elliptical galaxies can be over a million light-years in diameter. The smallest “dwarf elliptical” galaxies are less than one-tenth the size of the Milky Way! Elliptical galaxies have very little gas and dust.
Which is biggest galaxy in universe?
The biggest known galaxy is IC 1101, which is 50 times the Milky Way’s size and about 2,000 times more massive. It is about 5.5 million light-years across. Nebulas, or vast clouds of gas, also have impressively large sizes.
What is elliptical galaxy simple?
Definition of elliptical galaxy : a galaxy that has a generally elliptical shape and that has no apparent internal structure or spiral arms. — called also elliptical. — compare spiral galaxy.
Which galaxy is nearest to our galaxy Milky Way?
the Andromeda galaxy
Although several dozen minor galaxies lie closer to our Milky Way, the Andromeda galaxy is the closest large spiral galaxy to ours. Excluding the Large and Small Magellanic Clouds, visible from Earth’s Southern Hemisphere, the Andromeda galaxy is the brightest external galaxy you can see.
Are most elliptical galaxies cigar shaped?
As it turns out, the biggest and most luminous galaxies come in one of two basic shapes: either they are flatter and have spiral arms, like our own Galaxy, or they appear to be elliptical (blimp- or cigar-shaped). Many smaller galaxies, in contrast, have an irregular shape.
Some of the most popular examples of elliptical galaxies are Messier 32, Messier 60, IC 1101, NGC 50, Maffei 1, etc. On the other hand, some of the best examples of spiral galaxies―other than the Milky Way ―are Messier 31, Messier 101 , Messier 33 , Messier 51a, NGC 253 , etc.
What are the types of elliptical galaxies?
There are three main types of galaxies: Elliptical, Spiral, and Irregular. Two of these three types are further divided and classified into a system that is now known the tuning fork diagram. When Hubble first created this diagram, he believed that this was an evolutionary sequence as well as a classification.
What percent of galaxies are elliptical?
Elliptical galaxies probably comprise about 60 percent of the galaxies in the universe. They show wide variation in size — most are small (about 1 percent the diameter of the Milky Way), but some are about five times larger than the diameter of the Milky Way.
What are facts about elliptical galaxies?
Elliptical galaxies are found in compact galaxies. This of elliptical galaxies paints them as galaxies where star formation has finished after the initial burst, leaving them to shine with only their aging stars. Very little star formation is thought to occur, because of the lack of gas, dust, and space.
