Who invented the reflecting telescope?

Newton
A group of TWO stars held together by gravitational attraction is called a?

Binary System
Supergiant star that collapses and disappears from space is called?
Black Hole
The scientific study of the stars

Astronomy
Small and medium-sized star, our Sun
Dwarf Star
this instrument REFLECTS light off mirrors to make objects appear bigger.
Reflecting telescope
Define:
Blue Star & Red Star
Blue star: Color of the brightest star
Red Star: Color of the coolest star
Huge star system that cover many light-years of space is called?
Galaxy
The practice of finding guidance from stars
Astrology
constellations that revolve around the North Star
Circumpolar
This instrument collects RADIO waves using concave-shaped disk.
Radio Telescope
What is the difference in Absolute magnitude and Apparent magnitude?
Absolute: true brightness of a star
Apparent: how bright a star appears to be
A GALAXY shaped like a round or flattened ball, generally containing only old stars is called?
Elliptical Galaxy
Made of irregular shaped pieces of rock, metal, and dust
Asteroids
An existing star flares and becomes brighter is called?
Nova
This instrument bends light through lenses to make objects look bigger; uses convex and concave lenses.
Refracting Telescope
Contains three or four stars held together by gravitational attraction.
Multiple Star groups
Stars which go through periods of swelling and brightening, then shrinking and dimming; the absolute magnitude changes.
Pulsating Variable Stars
A cloud of dust, gases, and debris
Nebula
The apparent movement or change in position of one star in relationship to other stars is called?
Parallax

This instrument breaks down light given off by a star into all of its colors.
Spectroscope
Pairs of stars that orbit each other. When one star moves in front of the other, it eclipes the other stat.
Eclipsing Variable Stars
The wavelengths on a spectroscope demonstrate this when an object is moving away from the Earth.

Red Shift
What is the difference between:
Meteorite, Meteoroid, and Meteor
Meteorite: Chunk of metal or stone that come through Earth's atmosphere and has landed on earth
Meteoroid: Chunk of metal or stone moving towards Earth's atmosphere
Meteor: Chunk of metal or stone that has entered Earth's atmosphere and light up due to friction as it passes through
Explain the difference between:
Global Cluster and Open Star Cluster

Globular Cluster: A group of several thousand to a million stars that form a ball
Open Star Cluster: A group of several hundred to a few thousand stars in NO arrangement
