Which Is The Smallest Galaxy In The Universe?

What is the biggest star in the universe?

Answer: The largest known star (in terms of mass and brightness) is called the Pistol Star.

It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright.

In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy..

What are the 4 types of galaxy?

In 1936, Hubble debuted a way to classify galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies. More than two-thirds of all observed galaxies are spiral galaxies.

How old is the youngest galaxy?

Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old. The newest galaxy we know of formed only about 500 million years ago.

What is beyond the end of the universe?

So, in some ways, infinity makes sense. But “infinity” means that, beyond the observable universe, you won’t just find more planets and stars and other forms of material…you will eventually find every possible thing.

What is bigger than a galaxy?

A supercluster is a large group of smaller galaxy clusters or galaxy groups; it is among the largest known structures of the universe.

How big is the smallest galaxy?

It is inside one of the densest galaxies known to date — the M60-UCD1 dwarf galaxy that crams 140 million stars within a diameter of about 300 light-years, which is only 1/500th of our galaxy’s diameter.

What is the heaviest thing in existence?

In terms of actual weight, the heaviest object ever directly weighed, according to Guinness World Records, is the revolving service structure of the launch pad at the Kennedy Space Center in Florida, clocking in at 4.86 million pounds.

Can you go infinitely small?

In physical reality – no. Anything infinitely small does not exist although some objects act as if they are point-like. In mathematical Real numbers – no. The set of Real numbers , , is defined to have the Archimedean property .

How old is our galaxy?

What are the smallest galaxies?

A dwarf galaxy is a small galaxy composed of about 1000 up to several billion stars, as compared to the Milky Way’s 200–400 billion stars.

Which is smaller galaxy or universe?

Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them!

What is the smallest thing in the universe?

As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.

What galaxy do we live in?

Milky Way GalaxyAll 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 fastest thing in the universe?

Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.

How small can a galaxy be?

about 80 light yearsThe smallest known galaxy is M60-UCD1, whose radius is about 80 light years [1]. It belongs to a class called ultra-compact dwarf galaxies.

Which is the largest galaxy in the universe?

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.

Which is the oldest galaxy?

GN-z11GN-z11 is currently the oldest and most distant known galaxy in the observable universe. GN-z11 has a spectroscopic redshift of z = 11.09, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).

What will happen to our galaxy in 4 billion years?

Four billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda. The galaxies as we know them will not survive. In fact, our solar system is going to outlive our galaxy. … Fueled by gravity, the two galaxies are hurtling toward one another at 402,000 kilometers per hour.
