What is Astronomy?

Astronomy - the scientific study of the universe

Astronomy, is the study is the scientific study of the universe about many discoveries, such as new planets, stars, black holes, and nebulas. Astronomy is also the study of star shines, and new energy sources on the earth. Astronomers protect catastrophes like collisions between Astroids, and Earth.

Objectives:

1. Describe the Characteristics of the universe in terms of time, distance, and organization.

2. Identify the visible and nonvisible parts of the electromagnetic spectrum.

3. Compare refracting telescopes and reflecting telescopes.

4. Explain how telescopes for nonvisible electromagnetic radiation differ from light telescopes.

Astronomy Vocabulary

Describe the Electromagnetic Spectrum

The Electromagnetic Spectrum is all of the wavelengths of Electromagnetic Radiation. The to different types of Electromagnetic Radiations are, the Invisible, and the Visible. The visible radiation is a form of energy, and can only be seen by the human eye. The invisible radiation can be detected by special instruments, that include: gamma rays, x-rays, microwaves, and inferred waves. Both visible, and invisible radiations come from stars, they both include wavelengths.

Comparing the Refracting and Reflecting Telescope

The difference between, A Refracting Telescope, and A Reflecting Telescope are: A Refracting Telescope uses, Lenses that clears shaped objects to blend light in special ways. When the lights blend through the lenses, that is called Refraction. A Refracting Telescopes have a set on lenses to gather and focus light from distant objects. Both Refracting, and Reflecting Telescopes are Olliptical. A Reflecting Telescope uses, two curved mirrors that reflect light from space. The Reflecting Telescope can also blend more light than the Refraction Telescope.

Invisible Light and Visible Light

The two different types of telescopes are: Invisible light, and Space Based Telescope. The Invisible Telescope detects invisible radiation, such as radio waves, gamma rays, x-rays, and infrared waves. The Space Based is a spacecraft that includes a telescope, and other instruments, to investigate planets, stars , and other distant planets. Here is an example of the Hubble Space Based Spacecraft.
