Question: What Is The Biggest Galaxy?

What does space smell like?

sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’.

Some astronauts have likened the smells of space to walnuts..

What are the three largest galaxies?

The three largest members of the group are our Milky Way (second-biggest), the Andromeda galaxy (biggest) and the Triangulum Galaxy. The other galaxies in the Local Group are dwarf galaxies, and they’re mostly clustered around the three larger galaxies.

What is the most heaviest thing in the universe?

The heaviest object in the universe is a black hole. It is so heavy, that all the known laws of physics break around it. Its gravity, which is directly proportionate to its weight, is so strong, that nothing can escape it, not even light.

Where does Earth sit in our galaxy?

Orion ArmEarth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy. Here we are part of the Solar System – a group of eight planets, as well as numerous comets and asteroids and dwarf planets which orbit the Sun.

How many dead bodies are floating in space?

However, of the roughly 550 people who have so far ventured into space, only three have actually died there. Bringing the universe to your door.

What is the oldest thing in the universe?

Astronomers have confirmed the discovery of one the oldest and most distant objects ever known in the universe — a star-forming galaxy 12.8 billion light-years away that started forming within a billion years of the Big Bang that kickstarted everything.

What is the smallest universe?

The Planck length A Planck length is 1.6 x 10^-35 meters (the number 16 preceded by 34 zeroes and a decimal point) — an incomprehensibly small scale that is implicated in various aspects of physics.

Does the universe have an end?

The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).

What is the hottest thing in the universe?

A CERN experiment at the Large Hadron Collider created the highest recorded temperature ever when it reached 9.9 trillion degrees Fahrenheit. The experiment was meant to make a primordial goop called a quark–gluon plasma behave like a frictionless fluid. That’s more than 366,000 times hotter than the center of the Sun.

Is the Milky Way smaller than most galaxies?

Size and mass The Milky Way is the second-largest galaxy in the Local Group (after the Andromeda Galaxy), with its stellar disk approximately 170,000–200,000 light-years (52–61 kpc) in diameter and, on average, approximately 1,000 ly (0.3 kpc) thick.

Where is heaven located in space?

The area of the upper astral plane of Earth in the upper atmosphere where the various heavens are located is called Summerland (Theosophists believe hell is located in the lower astral plane of Earth which extends downward from the surface of the earth down to its center).

How many galaxies have we named?

But perhaps that isn’t so surprising. With an estimated 100 billion to 200 billion galaxies in the known universe, it’s no wonder that the majority of galaxies that have been identified thus far go by a catalog number: M51, GN-z11, and IOK-1, for example.

Is the Milky Way an elliptical galaxy?

Just as the Earth goes around the Sun, the Sun goes around the center of the Milky Way. … The concentration of stars in a band adds to the evidence that the Milky Way is a spiral galaxy. If we lived in an elliptical galaxy, we would see the stars of our galaxy spread out all around the sky, not in a single band.

What is biggest galaxy or universe?

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 galaxy?

Dwarf galaxy NGC 5477 is one of many irregular dwarf galaxies.

What is beyond outerspace?

If by outer space you mean all that surrounds the Earth and stretches into all directions as far as people can see, then you’re talking about what astrophysicists call the universe. For there to be anything outside of the universe supposes that it has an edge, which is a problematic supposition for physicists.

What universe do we live in?

We 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.
