I'm a host of the 3rd season of Known Universe on the National Geographic Channel. All episodes have now aired in the US. Here's the trailer. I've written a series of articles on Ain't It Cool News about each episode:
301: Surviving Space
302: Treasure Hunt
303: Most Powerful Stars
304: Extreme Space Tech
305: Biggest Cosmic Blasts
306: Construction Zone
307: Escaping Earth
308: Beginning of the End
And here's an article about my participation in the series in the Santa Barbara Independent.
Another show I was on, Inside the Milky Way, is now on DVD.
I also write about movies -- I cover film festivals, but I also write about the science of movies:
Star Trek Into Darkness
Star Trek (2009) [And follow-up chat with writers]
Conversation with James Cameron on Avatar
Review article on Type Ia Supernovae as Stellar Endpoints and Cosmological Tools for Nature Communications [PDF].
I recently wrote a Nature News and Views [pdf] (for scientists, but written generally) on a simulation that smashed two white dwarfs together to produce a supernova. And together with much of my field, I wrote this white paper about the future prospects for research in thermonuclear (Type Ia) supernovae.
Help us to find supernovae using Galaxy Zoo: The Hunt for Supernovae! With our new project, the Palomar Transient Factory, we are taking data at such a high rate that we can't keep up with the discoveries. So we need your help!
I was the co-chair of the scientific organizing committee for a June, 2011 conference in Sydney, Austrialia, called Supernovae and their Host Galaxies. I was also recently on the SOC for a conference in the Netherlands called Observational Signatures of Type Ia Supernova Progenitors.
Video of two talks I've given at KITP (for scientists): 2009: What the hell is this?, and 2007: Is the brightest SN Ia really super-Chandra?
I wrote the supernova spectrum fitting program superfit. Contact me if you want to use it.
Sky & Telescope article I co-wrote: Nov. 2002, Anatomy of a Supernova: pdf
I'm a member of the Supernova Legacy Survey, which discovers and follows supernovae to probe the history of the expansion of the universe and determine the nature of Dark Energy. We've discovered almost 2000 likely supernovae: list. I'm also a member of Pan-STARRS1, which is also finding and following thousands of explosive and transient events in the universe.

Super-Chandra: In the Sept. 21, 2006 issue of Nature, I led a paper showing that the Type Ia supernova SNLS-03D3bb was the explosion of a white dwarf that exceeded the Chandrasekhar mass. Type Ia supernovae are thought to be the thermonuclear explosion of a white dwarf star in a binary system with another star. The white dwarf steals matter from the secondary star until it gets near the Chandrasekhar mass and explodes. But somehow this white dwarf exceeded the limit. Download the News & Views[pdf].

Evolving supernova demographics: In a recent ApJ Letter we showed that Type Ia supernovae in the early universe were on average 12% brighter than modern supernovae. This is because there was more star formation early on, and SNe Ia from young, massive stars are brighter.

Dark Energy: Our first-year cosmology results, published in Astier et al. 2006 show that the Dark Energy is consistent with Einstein's Cosmological Constant to within 9% statistical error. Our new results, released in 2011, provide a 5-6% constraint. If the Dark Energy is a cosmological constant, it has some pretty remarkable properties. That means it is a property of the vacuum of space itself. As the universe expands, the Dark Energy does not get diluted like normal matter.
I most recently taught Astro 1 at UCSB in spring 2011.
