Which of the following best describes why radio telescopes are generally much larger in size than telescopes designed to collect visible light?.
What is the point in the sky directly overhead called?
The point on the celestial sphere directly overhead for an observer is the zenith.
An imaginary arc passing through the celestial poles and through the zenith is called the observer's meridian..
Which part of the Sun has the greatest density?
Being a star, the sun's density varies considerably between its outer layers and its core.
On average, it has a density of 1.408 g/cm³, which is roughly one-quarter that of Earth.
However, models of the sun estimate that it has a density of 162.2 g/cm³ closer to the core, which is 12.4 times that of Earth..
Why is Mars red quizlet?
Why is Mars red? The iron within the dust reacted with oxygen, producing a red rust colour, while the sky appears red as storms carried the dust into the atmospher..

People around the world gave them names (like Orion the hunter or Leo the lion) and told stories about them.
Refraction refers to the bending of light rays as they pass from one medium to another.
Reflection is the bouncing light off of a reflecting surface.
By curving the glass surfaces to form lenses and mirrors, the refracted or reflected light can be made to pass through a point of focus.
The Great Red Spot is a long-lasting area of high pressure on Jupiter creating a persistent storm.
Located in Jupiter's Southern Hemisphere, it is the largest storm in our solar system, appearing as a giant red spot on Jupiter's surface.
It has existed for the last 150 years, possibly even longer according to NASA.
