According to the Jerusalem Post, new study published on Wednesday suggests that certain star clusters do not appear to be obeying current understandings of Isaac Newtons principles of gravity. (Most notably open star clusters, which develop when thousands of stars are born in a relatively short amount of time amid a cloud of gas.) Data from the European Space Agencys Gaia project provided the first accurate count of stars, and this allowed astronomers to analyse the speed, direction, and age of each star. What are the findings? When star clusters disperse, the stars that survive end up on two tidal tails, one that is dragged behind the cluster and another that is propelled ahead of it.
