<h2>
Answer: C) stars in these regions are hidden by interstellar dust grains.</h2>
Explanation:
Some areas of the Milky Way seem dark because those are areas of the galaxy that are hidden by huge columns of interstellar dust that we cannot see through the visible range of the electromagnetic spectrum (which is the range in which our eyes see).
However, to solve this problem, astronomers use telescopes that work in the range of infrared and radio waves, to observe a little more through this intersetelar dust.
The best answer is C.
Mercator projection is a type of map projection invented and introduced by Gerardus Mercator in the year 1569. The meridians are equally spaced, parallel vertical lines and the parallels of latitude are parallel horizontal lines spaced farther apart as their distance from the equator increases.
This projection is widely used for navigation charts because any straight line on a Mercator- projection map is a line of constant true bearing that enables a navigator to plot a straight-line course.
It is often described as a cylindrical projection but it must be derived mathematically.
The model were the sun is in the center of the solar system is called heliocentric.
Have a nice day! :)
