10 Facts about the Milky Way
- It’s warped.
- It has an invisible halo.
- It has over 200 billion stars.
- It’s really dusty and gassy.
- It was made from other galaxies.
- We can’t take pictures of it.
- There is a black hole at the center.
- It’s almost as old as the Universe itself.
Is the Milky Way galaxy dying?
Actually, the Milky Way may have died at least once around 7 billion years ago; it revived after a period of 2 billion years, during which a whole bunch of stars died, going supernova and ejecting their outer envelopes into space, filling the galaxy with material for making new stars.
Do we live inside 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. Outside the main spiral are about 200 ball-shaped clusters of stars.
Is the Milky Way eating itself?
In the short term, no. The black hole at the center of the Milky Way is 26,000 light-years away. Even if it turned into a quasar and started eating stars, you wouldn’t even be able to notice it from this distance. If a star gets close, without hitting, it’ll get torn apart, but still, it doesn’t happen very often.
What is the biggest thing in the Milky Way?
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!

- The Milky Way Is Vast.
- Just One Of Many Galaxies.
- Classified As A Barred Spiral Galaxy.

What 2 galaxies are colliding?
The Milky Way and the Andromeda Galaxy are on a collision course. A computer model developed by scientists at the Museum shows that the pair is bound to crash in about three billion years and merge into a single elliptical galaxy.
Do all galaxies have a black hole in the middle?
Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas. This chart shows the relative masses of super-dense cosmic objects.
How many suns are in the Milky Way galaxy?
The Milky Way has a mass of 1.5 trillion suns.
Where is Earth in the Milky Way?
Orion Arm
Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy. Here we are part of the Solar System – a group of eight planets, as well as numerous comets and asteroids and dwarf planets which orbit the Sun.
Will our black hole eat the Milky Way?
NASA said: “No. There is no way a black hole would eat an entire galaxy. “The gravitational reach of supermassive black holes contained in the middle of galaxies is large but not nearly large enough for eating the whole galaxy.”
Do all galaxies have a black hole?
Observational evidence indicates that almost every large galaxy has a supermassive black hole at the galaxy’s center. The Milky Way has a supermassive black hole in its Galactic Center, which corresponds to the location of Sagittarius A*.
