If an observer on the Andromeda galaxy looked back at us, how would the Milky Way galaxy look to him? Edge-on, spiral face on, or in between?
The Milky Way and Andromeda Galaxy are two of the largest and most well-known galaxies in the universe. They are spiral-shaped collections of stars, gas, and dust that are held together by gravity.
The Andromeda Galaxy is approximately 2.5 million light years away from the Milky Way. This means that it takes light 2.5 million years to travel from one galaxy to the other.
When viewed from the Andromeda Galaxy, the Milky Way appears to be in-between. This is because we are viewing it from a different angle than we would if we were inside the Milky Way.
Scientists use a variety of methods to determine the shape of the Milky Way from the Andromeda Galaxy. This includes studying the distribution of stars and gas, analyzing the rotation of the Milky Way, and using computer simulations to model its structure.
Yes, the Milky Way and Andromeda Galaxy are on a collision course and are expected to collide in approximately 4 billion years. However, the collision is not expected to cause any major disruptions to either galaxy, as the distance between individual stars is so vast that they are unlikely to collide with each other.
