SYSTEMS IN SPACE

TELESCOPES

• An optical device used to make far away objects look nearer
• Many different types of telescopes.
• Refracting telescope, Newton reflecting telescope, Schmidt-Cassegrain telescope.
• These are the most popular among amuture astronomers.
• Using telescopes scientists have discovered thousands stars and planets.

TELESCOPES

• Deep space telescopes are used in the atmosphere to look into deep space
• and scan the sky looking for new stars and planets.
• Telescopes use mirrors and lens to focus light and produce an image that is visible to you.

SPECTROSCOPES

• Helps us find out what stars are made of.
• We interpret data by looking at the light signals
• Astronomical spectroscopy,electron spectroscopy, roman spectroscopy
• In 1800, William Herschel tested to see which color emitted the
• hottest temperature, it was the red end.

SUNS

• Sun had 3 layers of atmosphere: photosphere, chromospheres, and corona
• It has a visible layer that is composed of penumbral filaments
• It orbits around the center of the Milky Way
• Approximate one million Earths could fit into the sun
• Stars are born into main sequence stars

COMETS

• Comets are composed of ice and dust on the outside.
• They are icy because they go so far from the sun.
• Comets' atmospheres are made up of various gases.
• Comets move in ellipses (oval paths) around the sun.
• When they swing in toward the sun, they accelerate.

COMETS (2)

• When they swing away from the sun, they decelerate.
• Swinging in towards the sun makes the tail of a comet.
• Comets are unique by their chemical makeup and the stars they orbit.
• Comets are categorized by how long it takes them to orbit around the sun.
• Comets are very fascinating because they don't last as long as planets.

RELATIONS

• Everything relates because :
• You use spectroscopes to view stars
• Comets revolve around stars
• Telescopes are used to view comets
• Spectroscopes and telescopes are both technology used to view space and the universe
