How far from Earth is the Milky Way?
about 27,000 light-yearsThe Milky Way is a spiral galaxy comprised of a bar-shaped core region surrounded by a flat disk of gas, dust and stars about 120,000 light-years wide.
Our solar system is located about 27,000 light-years from the galactic center within one of the disk’s four spiral arms..

What is the closest galaxy to us?
The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
How fast is the Milky Way moving?
1.3 million miles per hourThe motion that’s left must be the particular motion of our Galaxy through the universe! And how fast is the Milky Way Galaxy moving? The speed turns out to be an astounding 1.3 million miles per hour (2.1 million km/hr)!
Why can’t we see the center of the Milky Way?
Dust and gas are necessary to form stars, and most stars are formed within the spiral arms. Note that we can’t really see the center of the galaxy with our eyes because there is dust in the way! Annotated image of the Milky Way. The Galactic Center is unfortunately hidden by dark dust in visible light!
Where is the best place to see the Milky Way?

Where is Earth in the Milky Way?
The Solar System (and Earth) is located about 25,000 light-years to the galactic center and 25,000 light-years away from the rim. So basically, if you were to think of the Milky Way as a big record, we would be the spot that’s roughly halfway between the center and the edge.
Can you see the edge of the Milky Way?
We live in the Milky Way Galaxy, this means that every time we gaze at the night sky we are looking at the Milky Way Galaxy. More exactly the spiral arm closer to the galactic center one part of the year and in the other part we see the near edge of the spiral arm farther from the galactic center.
Can you see the Milky Way every night?
The Milky Way: How to See It in the Summer Night Sky. … The Milky Way used to be visible on every clear, moonless night, everywhere in the world. Today, however, most people live in places where it’s impossible to see the Milky Way because of widespread light pollution caused by lights left on all night long.

If you are in a particularly dark location and if the moonlight is not too bright, you may also see a faint band of light that stretches from horizon to horizon …
How far is Earth from the edge of the universe?
46.5 billion light-yearsThe comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction.
How many black holes are in the Milky Way?
Judging from the number of stars large enough to produce such black holes, however, scientists estimate that there are as many as ten million to a billion such black holes in the Milky Way alone.
