Description
Astronomers have new evidence of the gaseous remnants of the supernova of a population III star from just 700 million years after the big bang. Speaking of big bangs, DART smacked Dimorphos and produced a long trail of debris from the tiny asteroid, and Mercury reveals a surprisingling dynamic surface. Tune in for space news near and far and Nobel prize trivia with your astroquarks.

Foucault pendulum
Proving the rotation of the earth since 1851, Leon Foucault's bob on a wire is also a handy demonstration that the earth is a sphere. With its latitude dependent rotation period, take a Foucault pendulum with you on your planetary explorations to determine your location, and it doubles as a handy timekeeping device. Available in lengths from 10 to 30 meters, the Foucault pendulum provides a laid back focus for your next party or event, giving you plenty of time to ponder the connection of a simple pendulum, to geometric phases and parallel transport. Custom periods are available for an additional charge. The Foucault pendulum, exact time for life (Omega).
