Researchers at the Astronomical Observatory of the University of Warsaw have recently discovered two previously invisible stars deep within the Milky Way. These binary stars (two stars that effectively orbit each other) were found thanks to a star called Gaia16aye that is considerably farther away. A few years ago, astronomers noticed that Gaia16aye would occasionally “flash” for a day or so and then go back to its normal brightness without initiating a supernova. It wasn’t until this past January that it was determined that these flashes were due to gravitational lensing from the aforementioned binary stars that are not bright enough to be seen from Earth. Although dim, these two stars are still massive enough to create multiple pockets of magnification that allow us to get a brighter look at Gaia16aye. Even though they are completely invisible to us, scientists are still able to determine almost everything about them thanks to the effects of gravitational lensing. This is exciting news because if gravitational lensing events like this one can show previously invisible stars, astronomers might be able to uncover even sweeter scores (like black holes) within our very own Milky Way galaxy. Space, baby!
