When Chris Davis mentioned on the forum that he would be speaking at an event promoting Citizen Science I thought I’d go along and combine a bit of sightseeing with a bit of crowdsourcing. Last Tuesday’s Celestial Skies: Public Eyes evening was billed as an event to discover how people power is shaping modern astronomy. The DANA Centre in London had invited Chris to talk about Solar Stormwatch along with Zookeeper Rob Simpson to give an overview of Zooniverse projects and Stuart Eves from Surrey Satellite Technology Limited to talk about his research into William Herschel and the mystery of Uranus’ 6 moons and ring. Each speaker was given 10 minutes to do their stuff. Ali Boyle, curator of astronomy at the Science Museum made sure things ran to plan.
Rob was up first and talked about the success of Galaxy Zoo and how that led to the creation and expansion of the Zooniverse. He mentioned all the current projects including Old Weather and the upcoming Milky Way Project and Papyrus Zoo. Chris was next and did a great job of telling people about all things Solar Stormwatch and Stereo in his allotted 10 minutes and managed to cover details of the Stereo mission and the twin spacecraft, basics of solar physics, the idea behind Solar Stormwatch and what stormwatchers do. Stuart told the fascinating story of why he thinks William Herschel discovered Uranus’ ring 190 years before its official discovery in 1977 and why Uranus is shown as having 6 Moons on an 18th century orrery (built using Herschel’s observations) at a time when only 2 had been discovered.
Then followed a practical taster session with computers set up to have a go at Hubble Zoo, Moon Zoo and Solar Stormwatch. Lots of people tried out the sites and I saw a couple of groups working their way diligently through the Solar Stormwatch tutorials. Several people said that they would have a go at home when they had more time.
A Q&A session followed with some quality questions from the audience.
The first question concerned Earth’s magnetic field flipping.
Chris answered this one and said that this happens every 100,000 years or so and explained how a record of the magnetic field at the time was trapped in layers of sedimentary rocks.
Is there a link between climate change and solar activity?
Another one for Chris who explained that while a small amount of global warming could be down to solar activity the majority of it is man made. More here.
How did scientists feel about having amateurs involved?
Rob said that although a few professional scientists were naturally sceptical at first the majority welcomed the use of amateurs into the world of data collection. He stressed that while computers can do many things they are not so good at the complicated pattern recognition required for Zooniverse projects and there are only so many undergrads and PhD students around to use as data collectors! Chris said he was rather pleased to suddenly have 10,000 research assistants to help him out.
What is some people deliberately set out to spoil the results?
Rob assured everyone that each image or video is classified several times and that the nice Citizen Scientists by far outnumbered the idiots. (He actually used a slightly more colourful description but the effect is the same!)
Why do people do Citizen Science?
Rob answered this and referred to Jordan Raddick’s motivation study carried out using Galaxy Zoo data where the most popular reasons people gave for taking part were an interest in astronomy and being able to contribute to science.
The evening rounded off a bit of a solar themed day having spent most of the afternoon in the Science Museum where I saw these:
|A quarter size model of SOHO
London Science Museum
|De revolutionibus – Copernicus daring to make the Sun rather than the Earth the centre of the universe
The DANA Centre is a good venue for this type of event. They use the cafe space to host a variety of science themed talks so food and drink is available. If you get the chance I’d recommend going along.
The Natchos are good too.

Tin hats on everyone! Stormwatchers have been tracking a solar storm launched from the Sun on the 14th October. Analysis of your results shows that this storm, travelling at 244 km per second, will cross Earth’s orbit at 14:43 GMT on the 21st October just 37 degrees ahead of our planet. While this is not expected to be a direct hit, we may still suffer a glancing blow so look out for auroral displays around this time. Stormwatchers have enabled this forecast by participating in the ‘Incoming -Trace it’ activity and have been doing such a great job that we can now start to issue warnings ahead of their arrival at Earth. Thanks to everyone for your hard work and patience. The more people we have looking out for and tracking these storms, the better our forecasts will be, so tell your friends!
