Forms of the estimator tailored for the Milky Way Galaxy and for M31 are given. Monte Carlo simulations are used to quantify the uncertainty as a function of sample size.For the Milky Way Galaxy, the satellite sample consists of 26 galaxies with line-of-sight velocities. We find that the ...
After a spectacular series of close passes lasting billions of years – and which will distort the structure of both galaxies – a final merger of the Andromeda Galaxy and the Milky Way galaxy will occur about 10 billion years from now. 6 beautiful galaxy collisions seen by the Hubble Space ...

New analyses of the x-ray and gamma-ray emissions from the center of the Milky Way galaxy, the Andromeda galaxy, and the Perseus galaxy cluster have detected significant signs of two possible dark matter particles. One is likely a 7.1 keV sterile neutrino, and the other appears to be a 35...
Andromeda Galaxy Facts The Andromeda Galaxy (M31) is the closest large galaxy to theMilky Wayand 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 ...
In about 5 billion years time, nearby massive galaxy Andromeda will merge with our own galaxy, the Milky Way. There haven't been any large mergers with our galaxy recently, but we can see the remnants of galaxies that have previously been snacked on by t
从仙女座星系向东看(Looking east from the Andromeda Galaxy) 仙女座星系与银河系(Andromeda and Milky Way Galaxies) 越过南北线到达仙女座星系(Over the North-South Line to Andromeda Galaxy) 来自超星系团的银河系和仙女座星系(Milky Way and Andromeda galaxies from the Supercluster) ...
The Milky Way's nearest neighbor is headed directly towards our galaxy, sooner than astronomers thought
The Andromeda galaxy was previously thought to be two or three times the mass of the Milky Way, but a new tool for measuring the mass of galaxies reveals that our nearest neighbor is just about the same size as our own galaxy.
The Andromeda Galaxy is the largest in the local group of galaxies to which the Milky Way belongs, and twice its size. It is a spiral galaxy 2.3 million light-years away, and it is the most distant object visible to the naked eye. ...
