It indeed appears the Andromeda galaxy (M31) and The Milky Way (MW) are en route to a collision. This will lead to a merger of the two galaxies forming an elliptical galaxy. The flattened disc structure of M31 and MW comes about because their gas dissipated energy but conserved momentum: a disc is the minimum energy state at given angular momentum. The gas ...

In a few billion years, the Milky Way and Andromeda will collide. About 5 billion years, but it will take more than a thousand years for the galaxies to overlap. Chances are, there won't be any spectacular stellar collisions If the cores of the 2 galaxies collide, I would think it to be very likely that star systems will be effected and the ...

First of all: your coordinate system (as I understand it) is not "well defined". You only provide a line (Earth --> Mily way centre) and define that as the North-South axis. You don't give a reference for the east-west axis or the up-down axis. So, I'll assume that the East-West axis lies along the plane of the Milky way and up is where the Bo├Âtes Dwarf ...

The Kepler space telescope had a field of view along the so called Orion arm, or spur, of the galaxy. The same structure which we ourselves are inside. It basically looks along a line where the star density is the greatest within the distance that it could detect transiting planets. Less than 3% of the galactic diameter, I think. Note that the illustration ...

Flamsteed designations are assigned by John Flamsteed. He was an English Astronomer. Flamsteed Designations (Flamsteed Numbers) are numbers assigned to the stars for the purpose of identification and cataloguing. Flamsteed designation contained 2554 stars. Flamsteed designations for stars are similar to Bayer designations, except that they use numbers ...
