Science History

On Friday morning I leave home early and meet some guys for breakfast. I have been doing this for essentially my entire career. It coincides exactly with the broadcast of the weekly Storycorps project on the radio. Most days I would rather hear the news. But every now and again these are gems.

I teach in a school that does not yet celebrate Martin Luther King Jr. Day. If you, like me, would like to somehow celebrate the day while you teach science, the story of Ronald McNair offers a great opportunity. 

UDF SkyWalker V1.0

The Ultra Deep Field obtained by the Hubble Space Telescope is the deepest view into the sky by humankind to date. This image combines 800 frames with a total exposure time of 1 million seconds. The 10.000 galaxies that are visible have distances out to times where the universe was just 800 million years old, one seventeenth of its current age. For more info check the UDF press release at

For a wider but less deep view visit the GEMS Skywalker.


Awesome Hubble Ultra Deep Field tool. Great for opening devotions.

Poster and Handout

During next week’s Moonwatch event at Cardiff University, I’ll be manning a stand showing people how to use Twitter, Google Earth and the Internet to find satellites in the night sky. As well as showing them how to use Heaven’s Above, I’ll also be outlining my own projects OverTwitter, LookUp and Satellite KML.

I’ll also be talking about .Astronomy, Galaxy Zoo and how to view interesting and alternative wavelengths on Google Sky. I’m going to be busy!

Since most of my readers are in the US and Canada, you can download my poster about my own projects rather than fly all the way to Cardiff next week. You can also download this handout explaining these projects and providing links.

If you you are in the Cardiff area, then you’ll need to register to attend our Moonwatch event because it is full up! However, if you have a telescope of your own, I would suggest holding your own smaller Moonwatch event locally. Invite the neighbours round and have some drinks while you show them the Moon!
