  1. Astronomy By: Shannon Allen

  2. Vocabulary • Calendar - a system for organizing time • Year – the time required for the earth to orbit the sun once • Month – roughly the amount of time required for the moon to orbit the earth once • Day- the time required for the earth to rotate on its axis • Leap Year – a year in which an extra day is added to the calendar

  3. Vocabulary • Leap Year – a year in which an extra day is added to the calendar • Constellations – sections of the sky that contain recognizable star pattern • Altitude – the angle between the object and the horizon • Right Ascension – a measure of how far east an object is from the point at which the sun appears on the first day of spring • Declination – a measure of how far north or south an object is from the celestial equator • Celestial Equator – an imaginary circle created by extending earth’s equator into space

  4. Vocabulary • Light-Year – a unit of length equal to the distance that light travels through space in 1 year • Telescope – an instrument that collects electromagnetic radiation • Refracting Telescope – a telescope that uses a set of lenses to gather and focus light • Reflecting Telescope – a telescope that uses curved mirrors to gather and focus light • Electromagnetic Spectrum – made of all of the wavelength of electromagnetic radiation
