How many galaxies are like the Milky Way?
The Milky Way galaxy has satellite galaxies such as the Large and Small Magellanic Clouds. There are around fifty galaxies in the Milky Way, the largest of which is the Large Magellanic Cloud. This satellite galaxy has a diameter of only 14,000 light-years.
How are other galaxies similar to the Milky Way?
Designated SPT0418-47, this recently discovered galaxy has at least two major similarities to our own: a rotating disk structure and a bulge, a central, tightly packed group of stars around the core. It’s the most distant of the galaxies that resemble our Milky Way.
Which of the following galaxies is most like our own Milky Way?
The Andromeda Galaxy
The Andromeda Galaxy (M31) is the closest large galaxy to our Milky Way. It’s seen here with two satellite galaxies: M32 is the compact fuzzy object located to the right of the Andromeda Galaxy’s center, and M110 is the more extended nebulous object at the top left of the central galaxy’s nucleus.
Is Andromeda galaxy similar to Milky Way?
The Andromeda Galaxy, or M31, is the nearest large neighbor of our Milky Way, though it sits some 2.5 million light-years away. By some estimates, the Andromeda Galaxy contains roughly one trillion stars. And it stretches more than 200,000 light-years in diameter.
Which is biggest galaxy?
IC 1101
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.
Is Comet a galaxy?
The Comet Galaxy, a spiral galaxy located 3.2 billion light-years from Earth, in the galaxy cluster Abell 2667, was found with the Hubble Space Telescope. This galaxy has slightly more mass than our Milky Way….
| Comet Galaxy | |
|---|---|
| Distance | 3.2 billion light-years |
| Apparent magnitude (V) | 18.7 |

| Type | dIrr |
What does the Milky Way look like in the sky?
We’re in the Milky Way Galaxy, on an outer arm, and what we see in the sky is our view toward the center of the Milky Way. If you could fly up into space and get above our galaxy and look down, you’d see a giant spiral, kind of like a pinwheel. Early astronomers thought the Milky Way was a spiral galaxy much like the nearby Andromeda Galaxy.
Is this spiral galaxy a twin of the Milky Way?
(Image credit: ESO) Almost like a postcard from across the universe, astronomers have photographed a spiral galaxy that could be a twin of our own Milky Way. The distant galaxy, called NGC 6744, was imaged by the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the European Southern Observatory’s La Silla Observatory in Chile.
What is the Milky Way galaxy made of?
The Milky Way Galaxy is organized into spiral arms of giant stars that illuminate interstellar gas and dust. The sun is in a finger called the Orion Spur. (Image credit: NASA/Adler/U. Chicago/Wesleyan/JPL-Caltech )
How far away is the Milky Way galaxy?
The galaxy is now 2.5 million light-years away, but it is inexorably falling toward the Milky Way under the mutual pull of gravity between the two galaxies and the invisible dark matter that surrounds them both. If playback doesn’t begin shortly, try restarting your device.
