Quick Answer: What Are The 4 Types Of Galaxy?

What type of galaxies do we live in?

They come in a variety of shapes and sizes.

The Milky Way is a large barred spiral galaxy.

All the stars we see in the night sky are in our own Milky Way Galaxy.

Our galaxy is called the Milky Way because it appears as a milky band of light in the sky when you see it in a really dark area..

What is the closest galaxy to our galaxy?

Canis Major Dwarf GalaxyThe 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 is the rarest galaxy?

Astronomers just discovered a rare monster galaxy that grew rapidly in the universe’s early days — and then went quiet surprisingly fast. The newfound giant, known as XMM-2599, lies about 12 billion light-years from Earth, meaning that scientists are seeing the galaxy as it existed when the universe was quite young.

What type of galaxy is the Milky Way?

spiral galaxyThe Milky Way is a huge collection of stars, dust and gas. It’s called a spiral galaxy because if you could view it from the top or bottom, it would look like a spinning pinwheel. The Sun is located on one of the spiral arms, about 25,000 light-years away from the center of the galaxy.

What is the nickname of our galaxy?

The term “Milky Way”, a term which emerged in Classical Antiquity to describe the band of light in the night sky, has since gone on to become the name for our galaxy. Like many others in the known Universe, the Milky Way is a barred, spiral galaxy that is part of the Local Group – a collection of 54 galaxies.

How many galaxies are they?

100 billion galaxiesAll in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com.

Why is the Galaxy flat?

Solar Systems/Galaxies are flat because of the rotation of the central mass (star in case of solar system, while a supermassive black hole in case of a galaxy) around its own axis. … Because the sun rotates in a plane, the accretion disc was formed in the same plane, and the resultant planets formed in the same plane.

What is the oldest type of galaxy?

What is the biggest galaxy in the world?

IC 1101The 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.

How do galaxies die?

The process repeats: Gravity condenses gas into galaxies and stars, stars blow up and kick the gas out, gravity cycles the gas back in and makes new stars. … Without gas, it can’t form new stars; the old stars live out their lives and die, and eventually the galaxy dies too.

How old is our galaxy?

13.51 billion yearsMilky Way/Age

What are the 5 types of galaxies?

There are four main categories of galaxies: elliptical, spiral, barred spiral, and irregular. These types of galaxies are further divided into subcategories while at the same time other types of galaxies exist based on their size and other unique features.

What is the most common type of galaxy?

Dwarf galaxiesDwarf galaxies are the most common type in the universe. However, because they are relatively small and dim, we don’t see as many dwarf galaxies from Earth. Most dwarf galaxies are irregular in shape. However, there are also dwarf elliptical galaxies and dwarf spiral galaxies.

Can humans travel to another galaxy?

Intergalactic travel for humans is therefore possible, in theory, from the point of view of the traveler. … Traveling to the Andromeda Galaxy, 2.54 million light years away, would take 28 years on-ship time with a constant acceleration of 1g and a deceleration of 1g after reaching half way, to be able to stop.

What is the closest star to our sun?

Alpha Centauri AOf the three stars in the system, the dimmest – called Proxima Centauri – is actually the nearest star to the Sun. The two bright stars, called Alpha Centauri A and B form a close binary system; they are separated by only 23 times the Earth – Sun distance.
