Textbook Question
Chapter 1, Problem 25EAP
The star Betelgeuse s about 600 light-years away. If it explodes tonight, (a) we’ll know because it will be brighter than the full Moon in the sky. (b) we’ll know because debris from the explosion will rain down on us from space. (c) we won’t know about it until about 600 years from now.

Suppose we find an Earth-like planet around one of our nearest stellar neighbors, Alpha Centauri (located only 4.4 light-years away). If we launched a "generation ship" at a constant speed of 1500.00 km/s from Earth with a group of people whose descendants will explore and colonize this planet, how many years before the generation ship reached Alpha Centauri? (Note there are 9.46 ××1012 km in a light-year and 31.6 million seconds in a year.
When we look at a particular star, we are seeing it as it was 371 years ago. How far away from us (in meters) is the star? Take a year to be 365.25 days.

- A friend of yours who did not do well in her astronomy class tells you that she believes all stars are old and none could possibly be born today. What arguments would you use to persuade her that stars are being born somewhere in the Galaxy during your lifetime?arrow_forwardWhen was your star discovered? Who discovered it (scientists? Or well-known to ancient cultures?)arrow_forwardThe closest star to Earth, after the Sun, is Proxima Centauri, which is just over 4 light years away from us. A light year is the distance traveled in one year by light, which travels at about 300,000 kilometers per second. What is the order of magnitude of the number of kilometers that separate us from Proxima Centauriarrow_forward

You will get a very large number of km as your answer. To get a better feeling for how the distances compare, try calculating the time it takes light at a speed of 299,338 km/s to travel from the Sun to Earth and from Alpha Centauri to Earth. For Alpha Centauri, figure out how long the trip will take in years as well as in seconds.arrow_forwardIf the speed of light is 3.0 × 105 km/s, how many kilometers are in a light-year?

Star A is moving across (i.e., perpendicular to) our line of sight, Star B is moving directly away from Earth, and Star C is moving away from Earth, but at a 30° angle to the line of sight. From which star will you observe the greatest Doppler shift?
