We all know what stars look like, right?
00:06
But what if I told you this wild image of reds and purples, greens and yellows is actually
00:10
an image captured by a telescope looking at one of them.
00:13
This image was captured by one of Gemini South Telescope's newest bits of tech, the Gemini
00:17
High Resolution Optical Spectrograph, or GHOST.
00:20
The telescope was pointed at a star with the very catchy name HD 222925, and the image
00:26
is a high resolution capture of the light being emitted by it.
00:29
In every optical spectrum of light known to man, astronomers say while this is the
00:33
instrument's first outing, in the future it will likely be a quote, essential component
00:37
of the astronomer's toolbox.
00:38
That's because the light tells us more about a star than just its composition.
00:42
Science Alert reports that it can reveal the star's movement, and how it's spinning
00:45
or oscillating, and the content of the light can also tell astronomers how old it is and
00:49
where it came from.
00:50
This star is around 1,460 light years away, and a spectral analysis has already shown
00:56
that it has the most complex composition ever discovered in a star, made up of some 65 different
01:01
elements, which experts say it likely formed when neutron stars collided, or after a catastrophic
01:06
supernova.
