Ep. 729: The James Webb Space Telescope

Streamed live on Sep 30, 2024. Let's talk about that giant telescope that's changing everything. We have been waiting our entire careers to make this episode on the James Webb Space Telescope, AKA the JWST. This historic Observatory was launched just a couple of years ago and it's already overturning our understanding of the early Universe star formation and exoplanets!

Streamed live on Sep 23, 2024. Last week, we talked about the Parker Solar Probe. As always, we like to talk about the person who inspired the mission. What makes this amazing and different is that Eugene Parker was there to watch the launch of the mission that shares his name. Why is he so influential on solar astronomy?

Streamed live on Sep 16, 2024. Let's look over the long life of the Parker Solar Probe as it explores the Sun and nearby worlds. The Sun! It’s that ongoing thermonuclear explosion that’s happening right over there! And although the Sun is necessary for life on Earth, we still have questions! So NASA has sent the Parker Solar Probe to visit the Sun up close, to get us some answers.

Streamed live Sep 9, 2024. We made all sorts of predictions, and some of the stuff we didn't know about last July, somehow, we still don't know about as we set up this episode on September 3! Join us for the first episode of Season 18 as we review all the crazy space science that happened during our Summer Hiatus.

Here’s what we’re excited about for the future. Especially for the next couple of months until we return in September.

I also have a favor to ask - I'm working on a research project with my collaborator Sanlyn Buxener on what factors help and hinder people learning and doing science. Can you please take our survey? bit.ly/AstEco THANK YOU! - Pamela

Streamed live on Jun 10, 2024. Astronomers have discovered thousands of exoplanets, revealing entirely new types of worlds that we just don’t have in the solar system. It’s enough to start getting a rough sense of what kinds of planets are out there. What’s the big picture?

Here’s a familiar question: How’s the weather? We’re familiar with the weather on Earth and telescopes and missions are watching the weather on other planets in the Solar System. But for the first time in history, astronomers can now answer that question for exoplanets, located light-years away from us.

Most of the exoplanets we’ve found are around stars, where they belong. But a few have been found free-floating in interstellar space. The evidence is growing that there are a lot of them out there, maybe even more than planets with stars. How do they form and how can we learn more about them?

Streamed live on Apr 30, 2024. Our galaxy series continues with elliptical galaxies. Unlike other types, these are large, smooth with very few distinguishing features. They’re filled with red and dead stars, a clue to their evolution.
