Which is bigger Andromeda or Milky Way?

Which is bigger Andromeda or Milky Way?

By some estimates, the Andromeda Galaxy contains roughly one trillion stars. That’s significantly bigger than the Milky Way, which more recent estimates suggest is 150,000 light-years across (though the exact boundary of where either of these galaxies “end” is a bit nebulous).

What will happen if Milky Way and Andromeda collide?

Based on current calculations they predict a 50% chance that in a merged galaxy, the Solar System will be swept out three times farther from the galactic core than its current distance. They also predict a 12% chance that the Solar System will be ejected from the new galaxy sometime during the collision.

Is the Milky Way older than Andromeda?

For comparison, the diameter of the Milky Way’s disk has long been thought to be only about half that: around 100,000 light-years. And in terms of the stars present, the Andromeda galaxy’s stars are much older, and its star-formation rate is much lower: only about 20-30% that of the Milky Way.

Are the planets in the Milky Way?

It is located at only 12.20 light-years away from us, and it hosts four confirmed exoplanets. Scientists estimate that there are at least six billion planets that are similar to our Earth, present within our Milky Way galaxy alone.

Can the earth survive Andromeda collision?

Astronomers estimate that 3.75 billion years from now, Earth will be caught up amid the largest galactic event in our planet’s history, when these two giant galaxies collide. Luckily, experts think that Earth will survive, but it won’t be entirely unaffected.

Is anything bigger than a galaxy?

From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid.

Does space have a bottom?

The Bottom of the Universe. The universe has a bottom. That bottom extends infinitely outward and has an infinite sky above it, with an infinite number of stars and galaxies. The bottom is remarkably terrestrial, with gravity, mountains, lakes, forests, and sunshine, each of which deserves additional discussion.

What is the distance between Milky Way and Andromeda Galaxy?

Currently, Andromeda is about 2.5 million light-years away from the Milky Way. That’s about 25 times as far away as the Milky Way is wide. This is, obviously quite a distance, but is quite small considering the scale of the universe.

What are facts about Andromeda Galaxy?

Andromeda Galaxy Facts. The Andromeda Galaxy (M31) is the closest large galaxy to the Milky Way and is one of a few galaxies that can be seen unaided from the Earth. In approximately 4.5 billion years the Andromeda Galaxy and the Milky Way are expected to collide and the result will be a giant elliptical galaxy.

Are there aliens in the Andromeda Galaxy?

The Andromedans are a sapient alien species hailing from a terrestrial planet nicknamed Androm, in the Andromeda Galaxy. 1 Biology 2 Homeworld 3 Culture and society 4 History 5 Appearances Andromedans have been consistently described as beautiful and exotic creatures. Their bodies are iridescent and conical in shape, and somewhat resemble a mollusk’s shell. They also have three tentacle-like

How far is the Andromeda Galaxy from Earth in miles?

So the Andromeda Galaxy is about 15 quintillion (15,000,000,000,000,000,000) miles from Earth. Believe it or not, that’s not very far–at least, as galaxies go. Andromeda is so close that it is part of the Local Group of galaxies.
