Pamela Gay

Astronomer, Podcaster and CosmoQuest Principal Investigator

Astronomer Pamela Gay is probably best known as co-host of the Astronomy Cast podcast, but she is also Principal Investigator for the CosmoQuest virtual research facility. It offers fun and rewarding citizen science opportunities, including its newest, Image Detective. She tells us how anyone can work with images of Earth taken by astronauts, turning them into terrific scientific resources. Bill Nye the Science Guy says the first observation of two neutron stars colliding is pure science gold. Distant dwarf planet Haumea has rings! Bruce Betts tells us about the Planetary Society’s connection to this story in this week’s What’s Up.
