Not all stars are bound so neatly like our Sun.
00:06
Some are soaring through the universe, more transient than even asteroids or comets,
00:10
which are still bound to the systems in which they orbit.
00:13
So where do these wandering stars come from?
00:15
Well, scientists have had many theories,
00:17
one of which involves massive galactic gravitational interactions,
00:20
which force stars out of their galaxies and into the cosmos.
00:23
But after tracking the light from these homeless stars back 10 billion years,
00:26
they found they've been on their own for at least that long.
00:29
Meaning it must be something else.
00:30
James G., one of the astronomers from the University of South Korea,
00:33
who is working on figuring out where they come from,
00:35
had this to say about it.
00:36
We don't exactly know what made the stars homeless.
00:39
Current theories could not explain our results,
00:41
but somehow they were produced in large quantities in the early universe.
00:44
Adding that in the early days of the universe,
00:46
smaller galaxies that formed likely didn't have strong enough gravitational pull,
00:50
leading to more stars being lost to intracluster space,
00:53
resulting in more light between galactic clusters still today.
00:59
Totally.

Thank you,
01:01
and that's it for now.
01:02
Anyway,
01:03
please give us a question.
01:05
Join us,
01:07
please.
01:08
We'll see you next time.
01:09
Please,
