Episode notes
Panic at the Disks
- Richard Panek discusses the "Panic! at the Disks" paper, claiming early galaxy formation challenged Big Bang theory.
- Follow-up observations and corrections mostly resolved the discrepancies, supporting existing theories.
JWST's Infrared Advantage
- JWST's infrared capabilities allow it to see deeper into the universe than Hubble, revealing earlier galaxy formations.
- This is because infrared light penetrates dust and stretches with the universe's expansion.
Dimethyl Sulfide Discovery
- Panek witnessed the cautious announcement of a potential dimethyl sulfide discovery on K2-18b, hinting at extraterrestrial life.
- Confirmation requires further investigation as the data is currently at a three sigma level.
