Look Up! September 2026

What’s in the night sky this September? Royal Observatory Greenwich astronomers Gideon and Catherine cover this month’s must-see cosmic objects and events in this podcast. We bring on our fellow astronomer Tania de Sales Marques to answer a visitor question. As usual, our hosts also discuss this month’s cosmic news stories, including the story of the discovery of Neptune and where our germs might be able to survive on the Moon. Got a question about space? Send it to us at [email protected] and our team of astronomers will answer it in next month’s podcast.
