How many galaxies are in the universe?
Research released in 2016 revised the number of galaxies in the observable universe from a previous estimate of 200 billion (2×1011) to a suggested two trillion (2×1012) or more and, overall, as many as an estimated 1×1024 stars (more stars than all the grains of sand on planet Earth)..
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.
What are the 4 types of galaxies?
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.
Are there any human bodies in space?
In the last half-century, about 30 astronauts and cosmonauts have died while training for or attempting dangerous space missions. … 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 thinnest thing in the world?
GrapheneGraphene is a sheet-like substance made of carbon atoms bonded together in a repeating hexagonal pattern. It is the first essentially two-dimensional material ever made. Being the thinnest piece of matter in the world is just one of many superlatives that can be applied to graphene.
What is beyond the universe?
Astronomers think space outside of the observable universe might be an infinite expanse of what we see in the cosmos around us, distributed pretty much the same as it is in the observable universe.
What 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).
Which is the smallest galaxy in the world?
An ultra-faint collection of 1,000 stars orbiting the Milky Way is the most lightweight galaxy ever discovered, scientists say. The dwarf galaxy known as Segue 2 is bound together by a tiny clump of dark matter.
How big is our galaxy compared to the universe?
Today we are fairly confident that the Milky Way is probably between 100,000 and 150,000 light years across. The observable Universe is, of course, much larger. According to current thinking it is about 93 billion light years in diameter.
Which is the biggest 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.

What is the heaviest thing in the universe?
black holeThe 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.
What is bigger 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 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 does space smell like?
“Space,” astronaut Tony Antonelli has said, “definitely has a smell that’s different than anything else.” Space, three-time spacewalker Thomas Jones has put it, “carries a distinct odor of ozone, a faint acrid smell.” Space, Jones elaborated, smells a little like gunpowder. It is “sulfurous.”
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).
What is the largest animal that ever lived?
Blue whalesBlue whales are the largest animals ever to have lived.
How many Earths are in the universe?
There are a billion Earths in this galaxy, roughly speaking.
Will the universe last forever?
As long as the amount of stuff doesn’t go over a critical threshold, the universe will continue to expand forever, and eventually suffer heat death, freezing out. But if there’s too much stuff, the expansion of the universe will slow down and stop. Then the universe will begin to contract.
Does space ever end?
In theory, space goes on and on… Our part of space, or the observable universe, has a special shape: it is flat. That means if you and a friend each had your own rocket ship and you both took off and travelled in a straight line, for ever and ever, you would never meet.
How old is our universe?
13.8 billion yearsOur universe is 13.8 billion years old, a timescale much longer than the more relatable spans of hundreds or thousands of years that impact our lived experiences.
