What galaxy do we live in?
the Milky Way
We 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. 100 000 years to cross from one side to the other.
Are we in a galaxy or a universe?
In the vast, expanding space known as the universe, humans reside on a small, rocky planet called Earth. Our planet is part of a discrete solar system in an arm of the spiral shaped Milky Way Galaxy. Our galaxy is only one of billions of other galaxies that exist within the universe.
Where are we in the Milky Way galaxy right now?
We’re about 26,000 light-years from the center of the galaxy, on the inner edge of the Orion-Cygnus Arm. It’s sandwiched by two primary spiral arms, the Sagittarius and Perseus Arms.
What kind of galaxy is in the Milky Way?
spiral galaxy
The Milky Way is a huge collection of stars, dust and gas. It’s called a spiral galaxy because if you could view it from the top or bottom, it would look like a spinning pinwheel. The Sun is located on one of the spiral arms, about 25,000 light-years away from the center of the galaxy.
How many Suns are in our galaxy?
The Milky Way has a mass of 1.5 trillion suns.
What is the difference between the universe and the Milky Way?
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! NASA’s telescopes allow us to study galaxies beyond our own in exquisite detail, and to explore the most distant reaches of the observable universe.
What is larger than the universe?
No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.
What is the closest galaxy to the Milky Way?
Although 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, visible from Earth’s Southern Hemisphere, the Andromeda galaxy is the brightest external galaxy you can see.
Is our galaxy moving?
The Milky Way itself is moving through the vastness of intergalactic space. Our galaxy belongs to a cluster of nearby galaxies, the Local Group, and together we are easing toward the center of our cluster at a leisurely 25 miles a second.
Could we ever travel to another galaxy?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
How many black holes are in the Milky Way?
Astronomers estimate that the Milky Way has anywhere from 10 million to 1 billion stellar black holes, with masses roughly three times that of the sun.
Why is our galaxy called the ‘Milky Way’?
Well, even though i still can’t see it, it did look like milk to ancient civilizations. Our galaxy is named Milky Way because of its milky appearance as it spreads all over the sky. The name dates back to ancient Greece as the Greek word for galaxy derives from the word “milk” (gala).

Thus we call it “The Milky Way” instead of “the galaxy” or “our galaxy”. So that name refers to both that river of light across the sky, which is part of our galaxy, and the galaxy as a whole. When…
Is our galaxy located 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…
