What are the 4 types of galaxies?
“The smallest of galaxies contain a “mere” few hundred million stars while the largest galaxies contain up to one hundred trillion stars! Scientists have been able to segment galaxies into 4 main types: spiral, elliptical, peculiar, and irregular.”
Is the Milky Way a barred spiral galaxy?
“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 are the 3 types of galaxies in the universe?
“What Kinds of Galaxies Are There? Astronomers classify galaxies into three major categories: elliptical, spiral and irregular. These galaxies span a wide range of sizes, from dwarf galaxies containing as few as 100 million stars to giant galaxies with more than a trillion stars.”

Which is the largest known galaxy?
“The biggest known galaxy, first described in a 1990 study from the journal Science (opens in new tab), is IC 1101, which stretches as wide as 4 million light-years across, according to NASA (opens in new tab). Galaxies are often bound to each other gravitationally in groups that are called galaxy clusters.”

How many galaxies are there in universe?
“By multiplying this number by the number of times this tiny patch of sky would fit into the entire sky, astronomers came up with an estimate of between about 100 and 200 billion galaxies.”
Which galaxy is the closest to Earth?
“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.”
How many stars in a galaxy?
“Using the Milky Way as our model, we can multiply the number of stars in a typical galaxy (100 billion) by the number of galaxies in the universe (2 trillion).”
What happens if 3 galaxies collide?
“In the case of three colliding galaxies, “the likeliest scenario is that two of them will find each other and form a binary system,” she said, and when the third arrives and starts interacting with the others, “the least massive one gets kicked out, and could actually be completely kicked out of the galaxy.” “You could …”
What’s larger than a galaxy?
“Superclusters form massive structures of galaxies, called “filaments”, “supercluster complexes”, “walls” or “sheets”, that may span between several hundred million light-years to 10 billion light-years, covering more than 5% of the observable universe. These are the largest structures known to date.”
What is our universe name?
“Our universe is also called the cosmos. It is originally a greek word. In early days it was thought that our Galaxy constituted the entire universe.”
How many universes are in space?
“While estimates among different experts vary, an acceptable range is between 100 billion and 200 billion galaxies, said Mario Livio, an astrophysicist at the Space Telescope Science Institute in Baltimore, Maryland.”

What is bigger than universe?
“No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.”
Is galaxies bigger than black hole?
“And while those black holes truly are massive — weighing millions, or even billions, of solar masses — they are tiny compared with their home galaxies, reaching less than 1% of the mass of a typical galaxy and a volume a billion times smaller.”

How many galaxies does the earth have?
“If we made the most straightforward estimate using today’s best technology, we’d state there are 170 billion galaxies in our Universe. But we know more than that, and our modern estimate is even grander: two trillion galaxies.”
