A telescope is a true...

When you look out into space, you look back in time. You see the Universe as it WAS, not as it is. That's because it takes TIME for light to travel from its source to your eyes. Light from the Sun takes about 8 minutes to reach you. Light from the next nearest star takes several YEARS to get here! |

CHALLENGE #9: HOW FAR BACK IN TIME CAN YOU SEE? | |
|
Using the telescope, capture ANCIENT LIGHT. How far back in time can you see?
To find out how far away (and therefore how old) an object is that you're imaging, you'll have to do some outside research. We'll give you hints from time to time. Send us your images and we'll publish them on this page. (To contact us, just e-mail us and send your image as an ATTACHMENT.) Good luck! |
 Teacher John Everhart and his class at N. Davidson HS in N. Carolina took this image of the galaxy called NGC253. The light that made this image left the stars in this galaxy 8 million years ago... so you're literally looking back in time 8 million years! |
