Tools That Help Us See Celestial Objects SPACE

Learning Goals To be able to describe the tools available to explore space

Astronomers cannot conduct experiments on celestial objects They can only observe them at a distance Today’s technology allows us to see farther into space than ever before

Telescopes Allows us to see objects that are very far away

Refracting Telescope Uses lenses to magnify images

Reflecting Telescope Uses a series of mirrors

Telescopes in Space Earth’s atmosphere prevents images from being as clear as they could be Telescopes are often placed on high mountains or in space to get a clearer view of the sky In 1990, the Hubble Space Telescope (HST) was launched into orbit around Earth

Light Pollution Excess light produced by cities and towns at night

Success Criteria I CAN describe the tools we can use to explore space
