Back in 2005, we developed a video podcast for NASA’s Sun-Earth Education Forum (see Traditions of the Sun). Soon after we were invited to became part of listserv which included everyone who podcasts at NASA. A master list of all NASA podcasts has been compiled and floating around the group for sometime now but it has ever been published. I asked Bryan Walls who administers the group if we could publish it, knowing it would be of interest to some of you.

Here’s what should be a complete list of all NASA sponsored public podcasts.

We’ve just finished developing version 1.0 of the Solar Viewer widget this time as a Dashboard Widget for Mac OS X. Earlier in the year we developed a Yahoo! widget version that works with both Mac and Windows, although you’ll need the Yahoo! Widget Engine to make it go.
Both versions (Yahoo! and Mac Dashboard) show the latest images of the sun from NASA satellites and ground-based observatories. More information about the images and links to larger images are provided. We first collected all of the amazing solar images for the Sun Earth Viewer, a Flash-based interactive that we developed with NASA back in 2004.

If you’re interested we posted a how-to for Yahoo! Widgets when we developed the first version of the Solar Viewer. We hope to have some time in the next couple of weeks to do something similar for the Mac version.

The Dashboard widget should be available on the Apple site soon. In the meantime, you can download it from Solar Viewer Widget page in the Ideum portfolio.

This Sunday the third Mayan World Alive! event will be held, this time in San Rafael, California at the Pickleweed Community Center. The event is free. (The previous two openings were held at the Mexican Consulate in San Francisco and the Governor’s palace in Merida, Mexico). This cultural event and exhibit will feature activities, music, dancing and a photographic exhibit showing some of the photographs we took for the Traditions of the Sun project last year. NASA’s website has more on the traveling photo exhibit.

Sunrise at Dzibilchaltun in the northen Yucatan. The building is known as the Sun Temple or the House of the Seven Dolls. This Late Classic building functioned as an observatory by marking the equinoxes, as well as the summer and winter solstices.

The Caracol, or Observatory at Chichen Itza served as an observatory for gathering astronomical data about the sun, moon, and planet Venus. Having the opportunity to shoot aerial photos was one of the highlights of the project. There is a slideshow with more aerial photograhs.

The Great Palace of Sayil is a beautiful and often overlooked struture. Sayil is located just a few kilometers from the more famous site of Uxmal.

El Castillo, or Castle, is the central pyramid of Chichen Itza. Notice the shadow on the right side of the pyramid. This appears as a great serpent which descends the staircase throughout the afternoon hours during the equinox. This photograph was taken in Spring of 2005. As you can see, huge crowds come to witness the event.
