Description

From December 25, 2025.

In this week's episode, we look at planets younger than fossils, celebrate relativity repeatedly working as expected, and peer at previously only theorized 1st generation stars using JWST. We celebrate the completion of the construction of the Nancy Grace Roman Space Telescope, and look in on all the recent launches. All this and more is coming to you right here, and right now!
