Is there anything in between galaxies?
The space between stars is known as interstellar space, and so the space between galaxies is called intergalactic space.
Intergalactic space is as close as you can get to an absolute vacuum.
There’s very little dust and debris, and scientists have calculated that there’s probably only one hydrogen atom per cubic meter..
What is the galaxy with the most stars?
IC 1101The Biggest of the Big Located 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 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 are the 4 types of galaxy?
This classification system is known as the Hubble Sequence. It divides galaxies into three main classes with a few variations. Today, galaxies are divided into four main groups: spiral, barred spiral, elliptical, and irregular.
What is outside 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.
Can a star exist outside a galaxy?
No, not all stars are in a galaxy. They may have once belonged to a galaxy, but they are not a part of it any more. Some of these so-called “stellar outcasts” or “intergalactic stars” have actually been observed by NASA’s Hubble Space Telescope. … In other words, they are truly “intergalactic”, or between galaxies.
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 the oldest galaxy?
GN-z11GN-z11 is currently the oldest and most distant known galaxy in the observable universe.
What is the smallest galaxy in the universe?
the Milky WayAn 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.
What is the relationship between galaxies and stars?
A galaxy is a collection of billions of stars, gas, and dust. Our solar system is one of millions of solar systems found in our galaxy, the Milky Way. Galaxies are held together by gravitational attraction,much like a solar system. Billions of stars make up our galaxy, including our sun.
Which is the biggest galaxy in the universe?
The 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.
Can you see stars outside the Milky Way?
The answer is no – unless you count seeing the combined light of many billions of stars. From the Northern Hemisphere, the only galaxy outside our Milky Way that’s easily visible to the eye is the great galaxy in the constellation Andromeda, also known as M31. … This is the edgewise view into our own Milky Way galaxy.
Can humans travel to another galaxy?
Intergalactic travel for humans is therefore possible, in theory, from the point of view of the traveller. … Traveling to the Andromeda Galaxy, 2 million light years away, would take 28 years on-ship time with a constant acceleration of 1g and a deceleration of 1g after reaching half way, to be able to stop.
What is the largest body in the universe?
The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall. This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across!
