Presentation Transcript


Constellations we see all year round are called;

  • Circumpolar constellations

    Example of a circumpolar constellation is

  • Little Dipper or Big Dipper


The star that is (almost) locate over our North Pole is

  • POLARIS

    The constellation that includes POLARIS is the

  • Little Dipper (Ursa Minor)


What cultures are most noted for our stories of how the constellations came to be?

  • Ancient Greeks and Romans


What do astronomers use to measure distance to the stars?

  • Parallax

    What do we call the amount of light a star ACTUALLY GIVES OFF?

  • ABSOLUTE MAGNITUDE


This is the measure of light received from a star here on Earth.

  • APPARENT MAGNITUDE

    This is the distance light travels in one year

    Light year


How fast can light travel?

  • A. 25,000 km per hr.

  • B. 100,000 mi per hr

  • C. 300,000 km per hr

  • D. 300,000 km per sec

  • D


Which of these is true? Light can travel…

  • A. 9.5 x 10 12 km per sec

  • B. 9.5 x 10 12 km per year

  • C. 300,000 km per year

  • D. 3 x 107 km per year

  • B


In a star, what does color tell us?

  • The temperature of the star

    Color blue or white means

  • HOT

    Color red or orange means

  • COOL


What do we use to identify what elements make up a star?

  • Spectroscope to see the star’s Spectrum

    What part of the stars spectrum are we able to see?

  • Visible light-color


About the Sun;

Hottest and inner most layer, where the energy is produced, is the

  • CORE

    Layer of Sun’s atmosphere that gives off light is

  • PHOTOSPHERE

    Areas on the surface of the sun that are COOLER than the areas around them:

  • SUNSPOTS

Tell me about the Sun


How long for light to travel from Sun to Earth?

Next closest star (in distance)

List 2 examples of how energy from the Sun arrives here at Earth

1. 8 minutes

2. 4.2 light years (Proxima Centauri) it is 270,000 times farther from Earth than the Sun

3. visible light, infrared and ultraviolet radiation,

Tell me MORE about the Sun:

VOCABULARY


4. Fictional stories of how constellations came to be.

5. Measure of the amount of light a star really gives off.

This is used to indicate what elements a star is made of

4. Mythology

5. Absolute magnitude

6. spectrum


7. Used to graph stars using temperature and absolute magnitude.

Large cloud of gas and dust that BEGINS a new star.

Measure of the amount of star’s light as seen from Earth.

9. Apparent magnitude


The Earth spinning on it’s axis

The Earth moving in an ellipse around the sun.

Areas cooler than those around them on the Sun.

Huge stars that are very cool.

A place in the galaxy with a gravitational pull so strong even light cannot escape!

A large collection of stars, gas and dust held by gravity.

Light shifts as it moves towards or away from an object, what is that shift called?

15. Black hole

16. Galaxy
