<u>Alpha radiation</u> is a type of airborne particle that rapidly loses energy as it moves through the atmosphere, has weak penetrating strength, and can be prevented by clothing or a piece of paper.
<h3><u>Why does alpha radiation exist?</u></h3>
Two protons and two neutrons are bonded together to form an object resembling a helium-4 nucleus, which is what is known as an alpha particle, also known as an alpha ray, or alpha radiation. Although there are additional possibilities, they are often created during the alpha decay process.
The Greek letter, which begins the alphabet, is where the name "alpha particle" originates. Alpha is represented by the sign 2+. Net spin is zero for alpha particles. Alpha particles typically have a kinetic energy of around 5 MeV and a velocity in the area of 4% of the speed of light because of the mechanism of their generation in ordinary alpha radioactive decay.

When the Sun reaches the highest or lowest regions in the sky, Solstices happens.
Explanation
A solstice is characterized by the poles of the planet whose inclination is away from or towards the star where the planet orbits.

One in June and the other in December which will be the Northern hemisphere's longest day and southern hemisphere's shortest day.
The Persian Empire is the name given to a series of dynasties centered in modern-day Iran that spanned several centuries—from the sixth century B.C. to the twentieth century A.D. The first Persian Empire, founded by Cyrus the Great around 550 B.C., became one of the largest empires in history, stretching from Europe’s Balkan Peninsula in the West to India’s Indus Valley in the East. This Iron Age dynasty, sometimes called the Achaemenid Empire, was a global hub of culture, religion, science, art and technology for more than 200 years before it fell to the invading armies of Alexander the Great.
