Question 8 is asking us about resolution and why improved resolution is helpful to astronomers.
00:08
If you remember what resolution is, it's how close together two points of light can be before they become indistinguishable.
00:18
So let's say that what i'm drawing here is the view through a low resolution telescope.
00:25
What it's supposed to be showing you here is a telescopic view of two distinct stars.
00:36
In low resolution view we can't tell that both two distinct stars because a resolution is not high enough to make them both separate.
00:54
But with a high resolution telescope we can distinguish the two different objects more clearly.
01:00
In a high resolution view, we would be able to see the two separate stars.
01:09
So because they're so distant, without high resolution, they would look pretty close together, whereas with a telescope that has high resolution, we can distinguish them as two individual objects.
01:21
It also allows us to distinguish more detail in these objects that are at such far distances...
