On Discovering a Planet and the Art of Writing a Press Release

tran_snapOne notable aspect of research into extra-solar planets is that both the media and the wider public are very interested. The first press release that I ever wrote, on the discovery of the first planets by our Wide Angle Search for Planets collaboration, back in 2007, ended up in TIME magazine as number 6 in their “Top 10 Scientific Discoveries” of the year. But the days of easy publicity for merely discovering a planet have passed. With astronomers worldwide having now found over 1000 exoplanets, it is getting harder to find a new angle when writing a press release.

Exoplanet transit

Our WASP project uses arrays of cameras to monitor millions of stars in order to look for tiny dips in their light caused by a planet orbiting in front of them. This requires a huge data-processing operation and the need for sophisticated search algorithms to look for the transit events.

The big problem is that the data, being obtained looking through Earth’s atmosphere, are hugely noisy. In the end, we need a human to help out the computer algorithms and make a judgement about what is likely to be an actual transit event. And that requires looking at lots and lots of light-curves of lots and lots of stars.

When I got an email from a 15-yr-old schoolboy — Tom Wagg — saying that he was keen on science and asking if he could join my research group for a week of work-experience, I figured that a bright 15-yr-old would be as good at that sort of pattern-recognition task as the best computer algorithms. So, I trained him up by showing him all the planet-transit dips that we’d already found, and set him the task of finding more of the same in our extensive data archive. Continue reading
