Light requires some medium to pass through, what's the medium in the space, and How does sunrays enters into the earth.

The sun's energy reaches the Earth's surface through a process called radiation. The sun releases energy in the form of electromagnetic waves, including visible light, infrared radiation, and ultraviolet radiation. These waves travel through the vacuum of space and pass through the Earth's atmosphere.
As the sun's energy passes through the Earth's atmosphere, it interacts with the particles and gases in each layer. Some of the energy is absorbed, some is scattered, and some is reflected back into space. The amount of energy that reaches the Earth's surface depends on factors such as the angle of the sun's rays, the thickness of the atmosphere, and the composition of the atmosphere.
The Earth's atmosphere is divided into five layers: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has unique properties that affect the path of the sun's rays. For example, the troposphere is the layer closest to the Earth's surface and contains most of the Earth's weather. The stratosphere contains the ozone layer, which absorbs harmful ultraviolet radiation from the sun.
The greenhouse effect is a natural process that helps to regulate the Earth's temperature. As the sun's rays pass through the Earth's atmosphere, some of the energy is absorbed by the Earth's surface and then radiated back into the atmosphere. Greenhouse gases, such as carbon dioxide and water vapor, trap some of this energy and prevent it from escaping into space. This helps to keep the Earth's temperature at a habitable level.
The Earth's atmosphere acts as a shield, protecting us from harmful sun rays. The ozone layer in the stratosphere absorbs most of the sun's ultraviolet radiation, which can cause skin damage and other health problems. The Earth's magnetic field also helps to deflect harmful particles from the sun, such as solar winds and cosmic rays. Additionally, the atmosphere's composition and density help to filter out some of the sun's harmful radiation before it reaches the Earth's surface.
