00:03at the heart of the milky way lies a supermassive black hole named sagittarius a around which there
00:09are some mysterious stars they're a bit of an enigma to astronomers as our galactic center
00:14is believed to be too chaotic for star formation now a team of experts believe they may have
00:19discovered where one of those stars named s0-6 came from and they say it's likely an alien over
00:26the last eight years a team from miyagi university of education in japan have been tracking the star
00:30finding that not only is it accelerating but it also orbits sagittarius a extremely closely
00:36only 0.04 light years away during their observations they were also able to determine s0-6's chemical
00:42composition by the light wavelengths it releases finding it's extremely vacant of heavy elements
00:48meaning it's likely 10 billion years old the amounts of those lighter elements are also more
00:52similar to those that exist in dwarf galaxies specifically those that orbit our own meaning
00:57it's more than likely that while the milky way was gobbling those smaller galaxies one of those
01:01stars ended up getting drawn into orbit around sagittarius a with the researchers now calling
01:06s0-6 an extra galactic star
