Astronomy


 * 1) Does knowing how to use a scale on a map help you understand how to use scale to measure distances in the universe? How are they similar? How are they different? yes becuase then you already know how to use it. both measure using same lengths but there are a special number of feet in a astronomical unit. they are farther away and harder to measure.
 * 2) Vast distances in space are often measured in light-years. A light-year is the distance that light travels in one year, or about 6 trillion miles. Altair, a star in the constellation Aquila, is 16.6 light-years away, which means that the light we see now from that star left its surface 16 years and 219 days ago. Describe what was happening in the world when the light we are seeing from Altair first left that star. How far away is Altair in miles? The time that star started to travel to earth my parents where getting married.
 * 3) Explain why it would be impossible for scientists to measure stellar distances that are accurate to within a few feet. Why is it not critical to attain such accuracy when dealing with astronomical distances? Because if you are measure wrong you might not be able communicate with NASA if you where to go to the moon.
