Astronomers have managed to spot something quite unexpected at the outer rims of our Milky Way galaxy -- new stars forming.

How is this happening? According to Price-Whelan and his colleagues who presented their findings on January 8 at the American Astronomical Society meeting in Honolulu, spectral analysis has shown that these young stars are not of this galaxy and are actually from another. This means that these stars haven't formed from material located in the Milky Way, but have instead come from two close dwarf galaxies called the Magellanic Clouds.

Both of these galaxies are currently on a slow collision course with the Milky Way, and it seems that a stream of gas extending from the galaxies is making its way into the Milky Way and forming new stars. Primary discoverer Adrian Price-Whelan, a research fellow at the Flatiron Institute's Center for Computational Astrophysics in New York City, said "This is a puny cluster of stars-less than a few thousand in total-but it has big implications beyond its local area of the Milky Way". Price-Whelan also named the star cluster - Price-Whelan 1.

Jak's love for technology, and, more specifically, PC gaming, began at 10 years old. It was the day his dad showed him how to play Age of Empires on an old Compaq PC. Ever since that day, Jak fell in love with games and the progression of the technology industry in all its forms. Instead of typical FPS, Jak holds a very special spot in his heart for RTS games.
