Astronomy "Tools of Astronomy"
The bending of light.
A telescope that uses convex lenses to gather and focus light.
A telescope that uses a curved mirror to collect and focus light.
The maximum clarity or distinctness of an image made by an optical system.
A device built to observe distant objects by making them appear closer.
The Hubble Telescope
A reflecting telescope that orbits above Earth’s atmospere.
An instrument that collects and records radio waves traveling through space and can be used day or night under most weather conditions.
An instrument that can split light into different wavelengths. Is used to find the composition, temperatures, and speed of distant stars.
The unbroken band of colors showing the types of light.
The unevenly spaced series of colored wavelengths that show the elements present.
A continuous spectrum with dark lines where light waves are absorbed in order to determine a planets atmospheric composition.
A form of energy that travels in waves. These waves can travel through solid objects in order to show what lies beneath.
Electromagnetic radiation with wavelengths longer than visible light but shorter than radio waves.
The apparent change in frequency of electromagnetic or sound waves caused by the relative motions of the source and the observer.
The change in the wavelength of light due to an object moving away from you.
When motion causes a shift in light wavelength due to a object moving closer to you.
