LSST, Public Data, and NAM Hack Day 2014

Today is the start of the UK National Meeting in Portsmouth. I’ll be there tomorrow, and running the NAM Hack Day on Wednesday with Arfon Smith - which is going to be awesome. Today at NAM, the nation’s astronomers will discuss the case for UK involvement in the Large Synoptic Survey Telescope project - the LSST. The LSST is a huge telescope, and a massive undertaking. It will change astronomy in a profound way.

With every image it takes, the LSST will be able to record very a large patch of sky (~50 times the size of the full Moon). It will take more than 800 images each night and can image its* entire sky twice a week! Billions of galaxies, stars, and solar system objects will be seen for the first time and monitored over a period of 10 years. Crucially it will use it’s rapid-imaging power to look for moving or ‘transient’ things in the night sky. It will be an excellent tool for detecting supernova, asteroids, exoplanets and more of the things that move from night-to-night or week-to-week. For example, the LSST could be used to detect and track potentially hazardous asteroids that might impact the Earth. It will also help us understand dark energy - the mysterious force that seems to keep our universe expanding - by mapping the precise location of billions of galaxies.

I’ve recently become LSST:UK’s _Public Data Coordinator_ - think ‘chief hacker’ if you prefer. The LSST’s unprecedented archive of data will be a resource we can tap into to create new kinds of public outreach tools, data visualisations, and citizen science. In recent years, we at the Zooniverse have pioneered citizen science investigations of data in astronomy**. The citizen science and amateur astronomy communities around the UK, and the world, will be able to access the amazing data that comes out of the LSST both through structure, Zooniverse-style projects but also in a more freeform manner. The potential for discovery will be on a scale we haven’t seen before. It’s very exciting.

The LSST is a public-private partnership and is led by the United States. The unique scientific opportunities presented by the LSST have led to the formation of a group of astronomers from more than 30 UK universities. We’ll be asking for funding from the Science and Technology Facilities Council to support UK participation in the project.

If you’re at NAM this week, then I’ve love to talk about LSST, hacking on data, and Zooniverse. On Wednesday you’ll find me in the Park Building, at the University of Portsmouth at the GitHub/.Astronomy NAM 2014 Hack Day. I’ll also be at the GitHub drink up on Tuesday night at The White Swan from 7pm - where you can enjoy some of the finest cask ales, draught beers and wines in Portsmouth - and GitHub are paying!
