Milk Road and Andromeda will collapse in 4.5 billion years, notes the study

The Andromeda Galaxy is the nearest large galactic neighbor. The picture was taken by Hubble and consisted of 7,398 exposures that were recorded on all 411 telescopes. ( NASA, ESA, J. Dalcanton, B.F. Williams and L.C. Johnson (University of Washington), PHAT Group and R. Gendler )

The new study notes that it may take a little longer before the Milky Way meets Andromeda. Based on the observations of ESA Gaia spacecraft, the collision is likely to occur 4.5 billion years from now.

Neighboring galaxies

Previous estimates suggest that the collision between the Roman road and Andromeda will probably take place in 3.9 billion years. The analysis of the data collected by Gaia spacecraft shows that this will happen in 4.5 billion years.

In a new study, published in 2006. T Astrophysical diary, researchers followed the stars in the Roman Road, in Andromeda, as well as in the Spiral Triangle. In their view, two adjacent galaxies are located about 2.5 to 3 million light-years away from the Roman road and are close enough to each other to interact.

Milky Way and Andromeda collision

By tracing individual stars in galaxies, researchers were able to follow the levels of rotation of Andromeda and the Spiral triangle and to show how the galaxies in the past have moved and how they will probably move in the next billions of years. This gave them an appraisal that the crash will most probably happen in 4.5 billion years, and that it is likely to happen as a side cross, not a collision in the head.

When this happens, it is unlikely that our solar system will be disturbed by the distance between the stars.


Messier 31, better known as the Andromeda Galaxy, is our closest galactic neighbor. This is best seen in November and can be seen with the naked eye even in moderate light pollution.

Because it's so visible, it's hard to say who exactly discovered the galaxy. This was first recorded in the book of 964 A book of fixed stars Persian astronomer Abd al-Rahman al-Sufi.
