I hope everyone keeps reading about science when this finishes.

Current JobI’m a Professor of Astronomy
Queen’s University Belfast
Favourite thing to do in my job: I love to use very large telescopes, collecting light from astronomical objects that are usually millions of kilometres away.
My Work: I study comets and asteroids orbiting our Sun, including some that can hit us.
I’m an astronomer studying asteroids and comets orbiting our Sun. Asteroids are mostly made of rock, while comets are mostly made of ice. By measuring what they are like, we get clues to how our Solar system was born and how it has changed over time.
One of our main jobs is finding Near-Earth Objects which could someday hit the Earth. They can be the size of a small mountain, and travelling at 40,000 miles per hour. They don’t often hit us, but when they do the explosion can be hundreds, thousands or millions of times larger than a nuclear bomb.
I use telescopes all over the world. Sometimes I have to go and operate the telescope myself, sometimes I send students, and sometimes the data is taken for me and sent back to me in Belfast.
The telescope I am concentrating on using right now is called Pan-STARRS, and it is on the island of Maui in the Pacific Ocean. It has the largest digital camera in the world, and we use it each night to scan the sky and detect asteroids and comets.
So far we have found over 800 with Pan-STARRS in just 3 years, and none are on a collision course right now! Just in case, I work with another team of European scientists to work out how to stop a collision happening.
My Typical Day: I calculate some physics or measure some data, talk to other scientists, and teach physics and astronomy.
Every morning I check my email and reply to ones that have come in over night from colleagues in the United States. I work at a University so most mornings I will be doing some teaching, sometimes to a class of over 100 physics students. Other times I help students with their projects, like studying gases just above the surface of the Sun, or looking for comets around other stars.
After lunch I generally spend some time doing science. This could be discussing the latest results from students studying for their PhDs with me, or continuing the analysis of all the data we’re getting from the Pan-STARRS telescope. We’ve got over 7 million detections of asteroids and comets so far, so this is taking some time 🙂
All of this is changes if I’m away at an observatory. There the day starts in mid-afternoon when I wake up. I’ll prepare my plans for that night, have dinner before sunset, then be using the telescope all night until it gets light again at sunrise. And all on a mountain top over 9,000 feet high – I love living and working up there!
What I'd do with the prize money: Hold a competition for 11-12 year old school pupils – “What would you like to discover in space?”
I would hold a competition for students in their 1st year of secondary school.
To enter they will write about what they would like to discover in space.
The first prize will be a small telescope, with a pair of binoculars for the runner-up. These will let them see the craters and mountains on the Moon, the way I first saw it when I was their age. Maybe one day they’ll become an astronomer too.
Any money left over will pay for me to travel to the winning school to give a talk on being an scientist.
How would you describe yourself in 3 words?
Cheerful, enthusiastic, thoughtful.
What or who inspired you to follow your career?
My physics teacher, seeing the moon through a small telescope, and watching tv programmes about space.
Were you ever in trouble at school?
Yes, and hopefully my school teachers aren’t reading this.
If you weren't doing this job, what would you choose instead?
I’d try to be a photographer, but I’m not sure I’d be good enough.
Who is your favourite singer or band?
Queen – simply classic!
What's your favourite food?
What is the most fun thing you've done?
Snorkelling in Hawaii.
If you had 3 wishes for yourself what would they be? - be honest!
A much better memory … and I can’t remember the other two.
Tell us a joke.
What do you call a boomerang that doesn’t come back? A stick.
