EVERYDAY SCIENCE

Detailed explanation-1: -Astronomy is the study of everything in the universe beyond Earth’s atmosphere. That includes objects we can see with our naked eyes, like the Sun, the Moon, the planets, and the stars . It also includes objects we can only see with telescopes or other instruments, like faraway galaxies and tiny particles.

Detailed explanation-2: -Use of terms “astronomy” and “astrophysics" However, since most modern astronomical research deals with subjects related to physics, modern astronomy could actually be called astrophysics. Some fields, such as astrometry, are purely astronomy rather than also astrophysics.

Detailed explanation-3: -the “gases surrounding the Earth or any astronomical body” are called an atmosphere. Being outside in the day light to look upward when the Sun is off to the East or West, you may see that the sky is blue depending on the weather.

Detailed explanation-4: -In the past century or so, astronomy has been broadly split into two camps-observational astronomy (using telescopes and cameras to collect data about the night sky) and theoretical astronomy (using that data to analyze, model and theorize about how objects and phenomena work).

Detailed explanation-5: -ASTROPHYSICS: Applying the laws of physics in space. ASTROMETRY: Mapping celestial bodies. ASTROGEOLOGY: Examining rocks, terrain, and material in space. ASTROBIOLOGY: Searching for life outside Earth. 12-May-2022
