What is known as astronomical?

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.

What does astronomical do?

Astronomers are involved in the study of galaxies, stars, and planets using telescopes and even space-based equipment. Some astronomers may explore objects in the solar system while others study the origin of the universe, the nature of time, black holes, neutron stars, or other galaxies.

What is an example of astronomical?

Astronomy is the study of objects and phenomena beyond Earth, whereas cosmology is a branch of astronomy that studies the origin of the universe and how it has evolved. For example, the big bang, the origin of the chemical elements, and the cosmic microwave background are all subjects of cosmology.

What is normal adjustment in astronomical telescope?

Hint: Telescope in normal adjustment means the final image is formed at infinity. The magnification in a telescope is given by the ratio of focal length of objective lens to the focal length of eye-piece. Also for a lens, the magnification is the ratio of image distance to object distance.

What is an astronomical telescope Class 12?

The telescope is used to provide angular magnification of distant objects. The objective has a large focal length and a much larger aperture than the eyepiece because object is very far away. Light from a distant object enters the objective and a real and inverted image is formed at its second focal point.

Are astronomers physicists?

Physicists explore the fundamental properties and laws that govern space, time, energy, and matter. They may study theory, design and perform experiments, or apply their knowledge in developing materials or equipment. Astronomers study planets, stars, and other celestial bodies.

How does astronomy help us?
