Mikey Way made headlines not too long ago involving a strange discovery that’s been made near its center.
Experts have known the fact that the edges of our galaxy Milky Way are warping, but it seems that no one knows why.
Futurism reveals new data that’s been collected by the European space agency’s star-mapping satellite Gaia.
According to the latest information, the Milky Way’s disc, made up of hundreds of billions of stars, is warping while it’s slowly colliding with a smaller galaxy nearby.
In order to be able to reach this conclusion, a team of experts at the Italian National Institute for Astrophysicists in Turin studied the way 12 million giant stars move in our galaxy, as observed by ESA’s Gaia space telescope.
The research has been detailed in a paper that’s been published the other day in the journal Nature Astronomy, and it’s suggesting that the unique way in which the edges of our galaxy are warping is reportedly caused by “a recent or ongoing encounter with a satellite galaxy.”
Measuring the speed of the warping process
“We measured the speed of the warp by comparing the data with our models,” according to the lead author Eloisa Poggio of the Turin Astrophysical Observatory.
Her statement continued and detailed, saying that “Based on the obtained velocity, the warp would complete one rotation around the center of the Milky Way in 600 to 700 million years.”
Futurism highlights the fact that this is much slower than how long stars, including the Sun, take to make it all the way around the center of the Milky Way.
Some previous theories tried to explain warping by suggesting that the inner disk of the galaxy is spinning like an inclined spinning top, and this leaves ripples.
Anyway, all in all, experts did not reach a final conclusion yet, and the reason for the warping of Milky Way’s edges is still unknown.
