Question

why are the images of stars from the jwst a glimpse into the past? the stars are extremely ?, so it takes ? for their light to reach the jwst.

Explanation:

To solve the fill - in - the - blanks, we analyze the context:

First blank:

The sentence is about stars and the time it takes for their light to reach JWST. Stars are extremely "far away" (this makes sense as the distance of stars is a key factor in the time light takes to travel).

Second blank:

We know that the time light takes to travel is related to distance. The formula for time $t=\frac{d}{v}$, where $d$ is distance and $v$ is the speed of light ($v = c=3\times10^{8}\ m/s$). Since stars are far away, it takes a "long time" (like years, centuries, etc.) for their light to reach JWST.

Answer:

First blank: far away
Second blank: a long time
