00:00The Sun is massive, however, it looks tiny compared to the central star in a system 180
00:09light years away.
00:11Its red giant star called Ardoratus is around 350 times the width of the Sun and it is in
00:16its final stages of life.
00:18However, what's even wilder is that the surface of that star is bubbling and astronomers have
00:23recently calculated that those bubbles are gargantuan as well.
00:27Researchers say the boiling bubbles of Ardoratus are some 75 times the size of our Sun.
00:31So why are there bubbles?
00:33A star's heat is generated inside at its core with that heat then moving outward to its
00:37surface via convection.
00:39Our Sun does this too, but its bubbles are much smaller, only around 620 miles across
00:44or just smaller than the state of Texas.
00:47Astronomers say simply observing these bubbles is something that is blowing their minds as
00:50well with one of the researchers saying about it, we had never expected the data to be such
00:54high quality that we could see so many details of the convection of the stellar surface.
