From the classroom, to the Universe

Clouds, Planets and DIY Spectrometer

We had an overnight stargazing activity at school. Thanks to <insert sarc mark here> the LPA, clouds quickly hid the view of Jupiter, good thing we savored a few minutes observing Venus.   As minutes of hopelessly waiting for skies to move bit, the rain started to pour. We have  to move down stairs and stay for there rest of the night, good thing is that we’re a bit prepared so we just did the DIY Spectrometer. It’s something made from a cd, box and razor blades and works by diffraction grating.

It was around 4am when the skies got a bit clear and we had the chance to enjoy the sights of Saturn in its majestic ring, Mars with polar caps and the crescent Moon.

  1. Nice! If we could compare this with a known spectrograph, we could actually deduce the elements that makeup the light source! 🙂
