    astronomy, space, space exploration

    Edward Balaban is a research scientist at NASA Ames and the principal investigator of the Fluidic Telescope Experiment, or FLUTE. The idea is to create a giant lens in space out of a fluid that could maintain its shape in microgravity. The technology was recently tested during the Axiom-1 mission to the International Space Station.

    astronomy, space, space exploration

    In this week's Questions and Answers show, I explain why James Web still can't see the Big Bang, if black holes can "unblack hole" later in life and what is the cutest nebula in the Universe?

  • 815: Unistellar Smart Telescope with Dr. Franck Marchis

    May 3rd, 2022  |  54 mins 35 secs

    My guest today is Dr. Franck Marchis, a senior planetary astronomer and chair of the exoplanet group at the Carl Sagan Center of the SETI Institute and Chief Scientific Officer and Founder at Unistellar. Franck helps develop adaptive optics systems for research observatories and helped develop the fully automated eVscope telescope which helps amateurs do astrophotography and contribute to astronomical research.

  • 816: Collecting Micrometeorites with Scott Peterson

    May 3rd, 2022  |  48 mins 59 secs
    astronomy, space, space exploration

    Every day about 100 tonnes of space dust strikes the Earth's atmosphere. Most of these space rocks vaporize, but some fall to the Earth at meteorites. Did you know that there are particles from space falling on the roof of your house? My guest today is Scott Peterson. Scott collects micrometeorites from his house and takes pictures of them using a microscope. We'll talk about how to find them, identify them and photograph them for yourself.
