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 giant elliptical galaxy. ...
Andromeda Galaxy, great spiral galaxy in the constellation Andromeda, the nearest large galaxy. It is one of the few visible to the unaided eye, appearing as a milky blur. The Andromeda Galaxy is located about 2,480,000 light-years from Earth, and its di
Andromeda is larger than the Milky Way in terms of the distance it extends. However, the two galaxies are roughly comparable in mass, and it's hard to say which one is more massive. Colliding galaxies Andromeda and the Milky Way are slowly drifting towards each other, leading scientists to...
distance is currently estimated as 725 kiloparsecs (2.36 million light years). With a total luminosity roughly double that of our own Galaxy and an overall diameter of approximately 60 kiloparsecs, M31 is the largest of the established members of theLocal Group. It has at least four ...
Data NED database entry, Atlas of the Andromeda Galaxy Description At a distance of 2.5 million light years M31 is the closest major galaxy to the Milky Way, and conversly the most distant object observable with the naked eye - albeit as a small murky patch on the very edge of visibilit...
In the very early days, we hadn’t even measured the sideways (from our perspective) motion of either galaxy, and the assertion that they would most likely collide was based simply on their distance from each other, their speeds relative to each other, and their estimated masses....
However, he was correct in viewing the galaxy as an island universe like the Milky Way, although at such a small distance it would be much smaller in size than our own galaxy. M31 The Andromeda Galaxy (credit:- Adam Evans) In 1887, Isaac Roberts from his private observatory in Sussex, ...
the most distant objects visible to the naked eye (M33, the Triangulum Galaxy, is slightly farther). It is an enormous spiral galaxy much like the Milky Way. To find the galaxy, draw a line between β and μ Andromedae, and extend the line approximately the same distance again from μ....
The distance of the HVS to the Milky Way centre as well as the Sun at t0 is used to select trajectories that pass through the Milky Way and close to the Sun. The selection process is discussed at the beginning of Section \ref{sec:results}. After the first steps of the selection ...
"In fact, if you were to shrink the sun to the size of a sand grain, the distance to the nearest star would be measured in miles. That makes close encounters with other stars extremely unlikely, even during a galaxy merger," Sally Dodson-Robinson, a planetary scientist at the University...
