What is the tool used by ancient Egypt which helped in astronomy?
Astronomy was all done with the naked eye at that time. Perhaps the most notable tool that the Egyptians used was the plumbline, for estabishing a perfect vertical, this enabled the altitude of stars above the horizon to be measured more accurately.
Is astronomy and medicline still used today?
Astronomy, yes; mediciline, no.
A sentence with astronomical in it?
It means1) "of, pertaining to, or connected with astronomy" (the study of stars)2) "large in number or size"The idiomatic meaning of "huge," "having a high numerical value," or "exorbitant" (as in astronomical prices) came about because of the large numbers that are frequently used in astronomy, for the vast distances in space.
What is a word that starts with y and is somehow related to astronomy?
A Yagi antenna, which can be used for radio astronomy.
Why do telescopes used for astronomy not have prisms to make the image the right way up?
Because it's not important. Introducing a prism into the optical path would absorb some of the light, which is important. So the tradeoff is an easy choice for astronomers to make.

How are light and astronomy related?
Studying light is one part of astronomy. Things like the speed of light, how it travels, the spectrum of light are all things that are used in studying astronomy. Studying light emitted from a star can tell us all sorts of things about it, like how far away it is and how bright it really is.
What is an astronomy satellite?
Probably a satellite used for astronomy observations.Probably a satellite used for astronomy observations.Probably a satellite used for astronomy observations.Probably a satellite used for astronomy observations.
What is a measurement of distance based on the speed of light?
A unit that is commonly used in astronomy is the light-year - the distance light travels in a year.
What tool can be used to refract light?
A prism
How light year is measured?
A light year is a unit of length used in Astronomy to define distance. One light year is equal to just under 6 trillion miles.
What is a parasec?
A parasec is a length of distance usually used in astronomy that is equal to 3.26163626 light years.
Tool used to reset engine light dodge neon?
OBD 2 scan tool.
What is a light curve graph?
A light curve graph that displays an object's brightness over time mostly used in variable star astronomy.
What tool is used to brake light into a rainbowlike spectrum?
The prism does this.
Why a light year used in astronomy?
Because of the vast distances in space and a light year is the distance of light travelling at 186,000 miiles per second in one year.
How do scientists measure distances in space light years or CMEs?
Common units used in astronomy include astronomical unit; light-year; parsec.
