How long would it take us to get to the Andromeda Galaxy?
2.5 million yearsHow long would it take to get to the Andromeda Galaxy.
Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years to get there if (and it’s a huge ‘if’) we could travel at the speed of light..
Is the Milky Way visible every night?
You can see the Milky Way all year, no matter where you are in the world. It’s visible just so long as the sky is clear and the light pollution is minimal. However, the Milky Way also appears to move in the sky, as the Earth rotates.
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 old is our universe?
13.8 billion yearsWe now state, with confidence, that the Universe is 13.8 billion years old.

Is Lightspeed travel possible?
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. … So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.
What is the farthest star we can see with our eyes?
IcarusIcarus, whose official name is MACS J1149+2223 Lensed Star 1, is the farthest individual star ever seen. It is only visible because it is being magnified by the gravity of a massive galaxy cluster, located about 5 billion light-years from Earth.
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.
What is the next closest galaxy to the Milky Way?
the Andromeda galaxyAlthough several dozen minor galaxies lie closer to our Milky Way, the Andromeda galaxy is the closest large spiral galaxy to ours. Excluding the Large and Small Magellanic Clouds, which can’t be seen from northerly latitudes, the Andromeda galaxy – also known as M31 – is the brightest galaxy you can see.
What is the most powerful thing in the universe?
Quasars inhabit the centers of active galaxies and are among the most luminous, powerful, and energetic objects known in the universe, emitting up to a thousand times the energy output of the Milky Way, which contains 200–400 billion stars.
What is the oldest thing in the universe?
The search for extremely distant galaxies continues today. 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.
How many galaxies are they?
100 billion galaxiesAll in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com.
Will we ever visit Andromeda?
Will we ever travel to Andromeda? Highly unlikely. Andromeda is 2.5 million light years away. Even if we managed to build a ship that could go 99.9999999999999% the speed of light, it’ll take 2.5 million years to get there.
Where is the clearest sky in the world?
There is an easy way to get above all that air – go to the Atacama Desert in northern Chile. Here, in one of the driest, highest and clearest skies in the world is the small town of San Pedro de Atacama.
Will we ever reach another galaxy?
According to our current understanding of physics, an object within space-time cannot exceed the speed of light, which means an attempt to travel to any other galaxy would be a journey of millions of earth years via conventional flight.
Can you see the Milky Way with your bare eyes?
More than 100,000 light years in diameter, with more than 100 billion stars and at least as many planets, the Milky Way is arguably the most impressive feature of the night sky that you can see with the naked eye.
What 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. Nebulas, or vast clouds of gas, also have impressively large sizes.
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.
