What is one of the biggest limitations of studying stars?
Time and distance. We see stars years in the past from what is currently happening, and we can't actually travel to the stars to study them, we have to study them from light-years away
not being able to travel to them (not including our sun) and go inside them
Their distance from us. What they're made of, you can't land a rover on the surface.
The universe is constantly expanding. So u will never finish.
don't know maybe sun
