Expert Solution & Answer
Explanation of Solution
Astronomy is the study of the universe, and the astronomers are the scientists that work in the field of astronomy, that is, who studies the universe.
Now according to the astronomer, the universe is the collection of each of the thing that exists in the space, or it is the totality of all the space, time, matter, and energy.

Compare the values of the number of grains of sand in all earth’s beaches with the number of stars in the universe – which is greater?
Number of sand grains
Number of stars
They are about the same.
Astronomers frequently say that “there are more stars in the universe than there are grains of sand on all the beaches on the earth”. Given that a typical grain of sand is about 0.5 – 1.0 mm in diameter, estimate the number of grains of sand on all the earth’s beaches. The diameter of the Earth is 12,742 km.

Express that time in scientific notation.arrow_forwardParallaxes are measured in fractions of an arcsecond. One arcsecond equals 1/60 arcmin; an arcminute is, in turn, 1/60th of a degree (°). To get some idea of how big 1° is, go outside at night and find the Big Dipper. The two pointer stars at the ends of the bowl are 5.5° apart. The two stars across the top of the bowl are 10° apart. (Ten degrees is also about the width of your fist when held at arm’s length and projected against the sky.) Mizar, the second star from the end of the Big Dipper’s handle, appears double. The fainter star, Alcor, is about 12 arcmin from Mizar. For comparison, the diameter of the full moon is about 30 arcmin. The belt of Orion is about 3° long. Keeping all this in mind, why did it take until 1838 to make parallax measurements for even the nearest stars?arrow_forward
