00:13was captured by one of gemini south telescope's newest bits of tech the gemini high resolution
00:18optical spectrograph or ghost the telescope was pointed at a star with the very catchy name hd
00:23222925 and the image is a high resolution capture of the light being emitted by it in every
00:29optical spectrum of light known to man astronomers say while this is the instrument's first outing
00:34in the future it will likely be a quote essential component of the astronomers toolbox that's because
00:39the light tells us more about a star than just its composition science alert reports that it can
00:43reveal the star's movement and how it's spinning or oscillating and the content of the light can also
00:47tell astronomers how old it is and where it came from this star is around 1460 light years away
00:53and a spectral analysis has already shown that it has the most complex composition ever discovered
00:58in a star made up of some 65 different elements which experts say it likely formed when neutron stars
01:04collided or after a catastrophic supernova
