University researchers looking for 'black hole hunters'
ReutersA university has launched an appeal for "black hole hunters".
University of Southampton is looking for citizen scientists to search through telescope data to help identify black holes.
Volunteers will be trained how to identify the astronomical phenomena, and will only need a smartphone, tablet or computer.
The research is part of joint work into elusive black holes between Southampton and Open University.
Astrophysicists Dr Matt Middleton, Adam McMaster and Dr Hugh Dickinson are leading the joint-project.
Dr Middleton, from the University of Southampton, said: "We know our galaxy is teeming with black holes but we've only found a handful. You could help us change that."
What is a black hole?
- A black hole is a region of space where matter has collapsed in on itself
- The gravitational pull is so strong that nothing, not even light, can escape
- Black holes will emerge from the explosive demise of certain large stars
- But some are truly gargantuan, billions of times the mass of our Sun
- How these monsters - found at galaxy centres - formed is unknown
- Black holes are detected from the way they influence their surroundings

Black holes are invisible, and their gravitational pull is so strong that not even light can escape, making them incredibly hard to see - even with specialist equipment.
But Dr Middleton added that gravitational pull is also "how we can detect them" because it is "so strong that it can bend and focus light, acting like a lens that magnifies light from stars".
"We can detect this magnification and that's how we know a black hole exists," he added.

He continued: "All you really need is an interest in space", adding that people of all ages were encouraged to sign-up with no prior expertise required.
Black Hole Hunters previously analysed data from a ground-based telescope but has relaunched with a new set of data to analyse from a space-based telescope, called TESS.
Dr Dickinson, of The Open University, said: "Using the amazing data from the TESS satellite means that there's a good chance that one or more citizen scientists will be able to spot one of the elusive gravitational lensing events that we're looking for."
