According to scientists, galaxies will collide 600 million years later than previously thought
This is what is said in Earth Sky
C & # 39; 39 is the case of the interaction of M31 (Andromeda Nebula) with another large galaxy – M33. Galaxy of the Triangle, visible in the constellation of the same name. It is about 3.5 million light years from Earth, it is the farthest object visible to the naked eye.
M31 is much larger in the Milky Way and the collision of these galaxies in a few billion years will likely result in the demise of ours, which remains to be absorbed. A Neighbor
A group of US astronomers attempted to determine the actual trajectories of two galaxies one with respect to each other and with respect to us. We used data from the European Gaia orbital telescope, which measured the parallax of a number of the brightest objects of both galaxies. The location of the mass centers of galaxies and their movement relative to each other were calculated with it. The results obtained generally correspond to previously obtained data with less precision by the Hubble telescope.
It turned out that M31 and M33 are slowly approaching and stretching one towards the other. This will change the trajectory of the Andromeda nebula, which will cause the collision of our galaxy for 500 to 600 million years later, after 4.5 billion years.
