What is observational astrophysics?
Observational astronomy is a division of the astronomical science that is concerned with recording and interpreting data, in contrast with theoretical astrophysics, which is mainly concerned with finding out the measurable implications of physical models.
What is meant by observational astronomy?
Observational astronomy is a division of astronomy that is concerned with recording data about the observable universe, in contrast with theoretical astronomy, which is mainly concerned with calculating the measurable implications of physical models.

- Observatory.
- Metallicity.
- Gravitational Waves.

- Novae.
- Neutron Stars.
Who is known for observational astronomy?
Galileo Galilei The astronomer (also mathematician, physicist and philosopher) turned the new observational tool toward the heavens, where he discovered the four primary moons of Jupiter (now known as the Galilean moons), as well as the rings of Saturn.
Who is the father of astrophysics?
Angelo Secchi, S.J.
Angelo Secchi, S.J. was born in Reggio, Italy and died in Rome. He was a physicist and mathematician with remarkable ability and passion for astronomy.
Who is considered the father of observational astronomy?
Galileo Galilei
Galileo Galilei pioneered the experimental scientific method and was the first to use a refracting telescope to make important astronomical discoveries. He is often referred to as the “father of modern astronomy” and the “father of modern physics”.
Which instrument is used to observe planets?
telescope
A telescope is an optical instrument designed to make distant objects like stars, planets, appear nearer, containing an arrangement of lenses, or of curved mirrors and lenses, by which rays of light are collected and focused and the resulting image magnified.
Why is Galileo called father of observational astronomy?
He was inspired by the design of Dutch spectacles, which had already used lenses to see objects nearer. However, Galileo was indeed the first person to observe the sky with a telescope and come up with astronomical discoveries. He is, hence, called the father of observational astronomy.
Who was the first astrophysicist?
It began with Isaac Newton. While astronomy is one of the oldest sciences, theoretical astrophysics began with Isaac Newton. Prior to Newton, astronomers described the motions of “heavenly bodies,” as they were then called, using complex mathematical models without a physical basis.
What other tools help with observation?
The sense of sight probably has the most tools to help us observe and discover new objects. Telescopes help us see the rest of the Universe, that we cannot feel, smell or taste….VOCABULARY:
- binoculars.
- camera.
- discovery.
- eyeglasses.
- hand lens.
- microscope.
- telescope.
