Which universe do we live in?
the Milky Way GalaxyWe live on a planet called Earth that is part of our solar system.
But where is our solar system.
It’s a small part of the Milky Way Galaxy.
A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems..
How does galaxy look like?
What Does the Milky Way Galaxy Look Like? 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. … 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.
Which is the most beautiful galaxy?
The Andromeda galaxy is 2.537 million light-years away from Earth in the constellation Andromeda. Its ‘closeness’ to our planet makes it the most distant object visible to the naked eye on Earth.
What is the oldest type of galaxy?
Elliptical galaxiesElliptical galaxies. The oldest galaxy yet discovered is EGSY8p7. An elliptical Galaxy that is 13.13 billion light years distant! 6.7 million years after the Big bang.
Where is the sun in our galaxy?
The Sun, and everything that orbits it, is located in the Milky Way galaxy. More specifically, our Sun is in a spiral arm called the Orion Spur that extends outward from the Sagittarius arm.
What is biggest star in our galaxy?
VY Canis MajorisVY Canis Majoris This red hypergiant is among the largest known stars in our galaxy. It has an estimated radius between 1,800 and 2,100 times that of the Sun. At this size, if placed in our solar system, it would reach nearly to the orbit of Saturn.
How many different types of galaxies are there?
fourThere 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 largest known star?
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.
What is the youngest galaxy?
Dubbed Abell2744_Y1, the galaxy is so far away that it takes about 13 billion years for light from the galaxy to reach our neighborhood. That means it appears as it was just 650 million years after the Big Bang, scientists say. The universe is estimated to be about 13.8 billion years old.
What is the biggest galaxy in the universe?
IC 1101Located almost a billion light-years away, IC 1101 is the single largest galaxy that has ever been found in the observable universe. Just how large is it? At its largest point, this galaxy extends about 2 million light-years from its core, and it has a mass of about 100 trillion stars.
What galaxy do we live in?
the Milky WayWe live in one of the arms of a large spiral galaxy called the Milky Way. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre.
How many stars die each day?
We estimate at about 100 billion the number of galaxies in the observable Universe, therefore there are about 100 billion stars being born and dying each year, which corresponds to about 275 million per day, in the whole observable Universe.
What’s bigger than a galaxy?
Obviously Universe. Universe is way bigger than galaxies. There are more than 2×10^11 galaxies in the observable universe.
What is our galaxy called?
The Milky WayThe 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.
Which color star is the coolest?
redThe hottest stars tend to appear blue or blue-white, whereas the coolest stars are red.
What are the 3 main galaxies?
Galaxies are divided into three basic types: spirals, ellipticals and irregulars. Spiral galaxies get their name from the shape of their disks, in which stars, gas and dust are concentrated in spiral arms that extend outward from the central nucleus of the galaxies.
What are the most common galaxies?
What Are Elliptical Galaxies? Elliptical galaxies are the most abundant type of galaxies found in the universe but because of their age and dim qualities, they’re frequently outshone by younger, brighter collections of stars. Elliptical galaxies lack the swirling arms of their more well-known siblings, spiral galaxies.
