How does JWST use Infrared to View the Universe YouTube link

We will introduce you to discoveries of ancient times and cosmological marvels, as well as up-to-date current research. Check out Alan explaining how the James Webb Space Telescope images the cosmos with infrared light.


Kepler on Planetary Motion YouTube video link

Astronomy faculty and staff, and an occasional “historical figure,” introduce SMAP sessions with the background and tools relevant to the topic in question – what is significant, what science is involved, what questions exist, what methods are used, and what do our findings tell us?



Curious to know more?

Check out some of our recent SMAP sessions and experiments.

It's a Black Hole YouTube video link.

Black holes are admittedly one of the most fascinating and mysterious object in the Cosmos. How do the affect light? How do they affect space and time? If you passed the event horizon, is there ever a return? What would you see and feel?

Hunting for Exoplanets YouTube link.

How do we search for unknown planets outside our solar system? Analyze your own data with the transit method and learn how astronomers tackle the issues. Could there really be life?

Turtles all the way down YouTube link.

Ancient observers of the night sky only had their eyes, their curiosity and their imagination. Learn about successive attempts to understand the workings of our solar system in the science we call Cosmology.

Coloring the Cosmos YouTube link.

Take a fascinating journey try for yourself using your own color scheme to bring out the details of actual JWST images.

Impact Cratering YouTube link.

Use common materials available at home to measure crater diameter and depth. Use these data to graph potential energy based on the mass of the impactor and its height above the surface.

How far apart for a total eclipse YouTube link.

Here’s one for the teachers out there. A giant balloon, your eyeball and a pearl head pin is all you need to demonstrate a total solar eclipse to scale. Pretty cool!
