With a groundbreaking technique, astronomers have used a galaxy as a gravitational lens to backlight two hydrogen clouds, peering back 11 billion light-years at our early universe. Plus, volcano water on the Moon, a quadruple star system, and this week’s What’s Up takes a careful look at the Sun.

From January 11, 2020.

With Adam Frank.

At the American Astronomical Society's meeting Honolulu I got a chance to talk with Adam Frank about new research he's worked with Caleb Scharf, Jonathan Carroll-Nellenback and Jason Wright about the Fermi Paradox. They calculated how difficult it would be for aliens traveling at 10% the speed of light to settle the entire Milky Way, and it turns out, it's not as simple as you might think.

Using a first-principles approach, researchers have discovered that the differences in the rotational rate of the solar system are due to the inward and outward flow of cations and electrons. Plus, JWST’s first list of observations, a Starlink launch, dinosaurs, raining sand, and a review of episode two of this season’s “For All Mankind.”

From March 5, 2008.

Hopefully you’ve all recovered from part 1 of this set, where we make you sad about the future of the humanity, the Earth, the Sun and the Solar System. But hang on, we’re really going to bring you down. Today we’ll look far, far forward into the distant future of the Universe, at timescales that we can barely comprehend.

This week we feature some rising stars in African Astronomy! We're joined by high school learners Indiphile Madletyana and Thabo Maliea who both show great promise as aspiring astronomers, as well as Masters students Sumari Hattingh and Reikantseone Diretse who discuss studies of galaxy clusters using the Hubble Space Telescope. Check out the show notes at www.thecosmicsavannah.com for related links, pics, info and the full transcript.
