Rumpelstiltskin can spin straw into gold, but how do stars do it?

Find out at the planetarium show “Spinning Stars into Gold,” coming to the Edwin E. Ritchie Observatory at 7:30 p.m. Saturday, Dec. 9.

Astronomer Dave Fong will reveal how gravitational waves and gamma ray bursts can tell us how neutron stars can make gold in a galaxy far, far away.

BPAstro Kids will create take-home holiday cards with Dr. Erica in “LED Cards” at 4 and 5 p.m.

If the sky is clear, astronomers will be on hand with telescopes for public stargazing afterward.

Admission to the show is free to BPAA members; $2 donation suggested for nonmembers, $5 for families.
