The Milky Way is 100,000 light years across.

You don’t notice it, but as you read this article, the Milky Way that contains the Earth rotates at 210 km per second.

Although now, a team of scientists from the University of Oxford and University College London (UCL, for its acronym in English), affirm that this speed is diminishing.

According to the research of these astronomers, our galaxy is now rotating 24% slower than it was when it formed, almost 14,000 million years.

You probably don’t notice this change in speed either, but the finding helps us better understand how works and evolves our galaxy.
