- Utbildning
These podcasts are my discussion of NASA's Astronomy Picture of the Day. These are brief (3-5 minute) audio summaries of the picture posted on NASA's Picture of the Day website: APOD. Video versions of these are available on YouTube. I use these as the introduction to each of my introductory astronomy classes. Students will be able to access them here to review what was discussed in class. I appreciate any comments or suggestions which can be sent to: wagnerastronomy@gmail.com.

2024 June 24 - JADES-GS-z14-0: A New Farthest Object
In today's image, we see the galaxy known as JADES-GS-z14-0. This galaxy, recent imaged by the James Webb Space telescope is now known to be the most distant galaxy ever observed. The galaxy is seen about 300 million years after the Big Bang, just a fraction of the age of the universe.My podcasts are available in video form through this YouTube Channel (https://www.youtube.com/channel/UCWksELVw1LfYg6TiLQyjByw).This Podcast is an authorized New Media Mirror Site for APOD.
