Wild Card
100
Stars are grouped into patterns called THIS.
What is constellations?
100
This is the number of degrees north or south of the celestrial equator.
What is the declination?
100
How bright a star looks when viewed from the earth.
What is apparent magnitude?
100
THIS kind of telescope uses only lenses to magnify an image. It bends light.
What is a refractor telescope?
100
Our galaxy that includes our sun.
What is the Milky Way?
200
This old device helps determine the position and motion of the heavenly bodies by casting shadows in sunlight.
What is a Gnomon?
200
This is the longitudinal position measured in hours.
What is the right ascension?
200
The true brightness of how bright a star actually is.
What is absolute magnitude?
200
This telescope replaces the refracto's light-gathering objective lens with a mirror.
What is a reflector telescope?
200
This star is spinning rapidly and emitting radio waves at regular intervals.
What is a pulsar?
300
The kind of lens that is light-gathering.
What is an objective lens?
300
The stars real motion across the sky as we see it.
What is Proper motion?
300
These stars have a low actual brightness but are hot stars.
What are white dwarfs?
300
This telescope was launched in April 1990 by the Space Shuttle Discovery and stays above the earth's atmosphere.
What is the Hubble Space Telescope?
300
This is a revolving pair of stars where one passes in front of the other.
What is an Eclipsing variable star.
400
The ability of a telescope to bring out details in an image. The larger the object, the better, clearer image.
What is resolution?
400
The stretching of wavelengths of their own light with increasing distance.
What is a Red Shift?
400
These stars have a brighter absolute magnitude when looking at a white dwarf, a blue giant, and the sun.
What is a blue giant?
400
This breaks down light given off by a star into all its colors.
What is a spectroscope.
400
This is when a star increases its brightness by 20 mignitude and practically destroys the star. It is destructive to the star.
What is supernova?
500
Refractors that have lenses that produce a blurry fringe of color around the image.
What is chomatic aberration?
500
The movement of the star directly toward or away from us.
What is Radial motion?
500
These stars, including our sun, are small and medium-sized.
What is a dwarf?
500
Telescopes can help us know how far away a star or galaxy is measuring the distance in THIS.
What is light years?
500
Icy chunk of frazen gases, water, and dust that orbits around the sun.
What is a comet.
