Looking at Distant Objects Lecture tutorial answers

Q: Do the angles from above tell you anything about the actual distance between the barn and the house or the moon and star?

No. (An angle by itself doesnt tell you distance)---Even though the angle is the same, the house to barn is just a few miles but the Moon to star is trillions of miles. Using Figure 2, determine which star exhibits parallax.

Imagine that you have received six pictures of six different children who live near six of the closest stars to the Sun. Each picture shows a child on his or her 12th birthday. The pictures were each broadcast directly to you (using a satellite) on the day of the child's birthday. Note the abbreviation "ly" is used below to represent a light-year.

How long will it be before we get the light from the supernova event we will see the supernova in million years?

The train of light that is the signal from the star while it was alive is 50 million light years long. We will see the supernova event 40 million years from now. The light signal that comes from the remnant of the star after it blew up stretches over 60 million light years. The star blew up 60 million years ago.

Do the angles from above tell you anything about the actual distance between the barn and the house or the moon and star?

No. (An angle by itself doesn't tell you distance)---Even though the angle is the same, the house to barn is just a few miles but the Moon to star is trillions of miles. Using Figure 2, determine which star exhibits parallax.

How old does the star appear to be to us here on Earth quizlet?

How old does the star appear to us here on Earth? Imagine that you are observing the light from a distant star that was located in a galaxy 100 million ly away from you. By analysis of the starlight received, you are able to tell that the image we see is of a 10 million-year-old star.
