It’s been 15 years since Pluto was kicked out of the planet club. Are there any updates? Does Pluto have a chance of regaining planethood again?

Sep 27th: Wave/Particle Duality

by Astronomy Cast | Sep 27, 2021 | Astronomy Cast

Have you ever heard that photons behave like both a particle and a wave and wondered what that meant? It’s true. This week we discuss the experiments that demonstrate this, explain how scientists figured it all out in the first place.

As part of her trip to England, Pamela had a chance to sit down with Oxford astrophysicist Chris Lintott and record an episode of Astronomy Cast. From the first stars to the newest planets, molecules and the chemistry that allows them to form affects all aspects of astronomy. While most astronomers group molecules into three bins of hydrogen, helium and everything else, there are a few who do proper chemistry by studying the sometimes complex molecules that form between the stars.
