Caltech Astro

The California Institute of Technology (Caltech) is one of the premier scientific research institutions in the world, featuring researchers working on a variety of topics throughout the sciences. We are the scientists from the Department of Astronomy, happy to answer questions about astrophysics and space science.

​

Caltech Astro hosts an activity to build a mini-comet using household materials, and demonstrates a solar telescope to enable people to safely view the sun. Another demonstration will ignite marshmallows with solar radiation!
