While invisible themselves, these cosmic behemoths reveal their presence by bending the light of nearby objects, and the Black Hole Hunters project is searching for one specific manifestation of this effect.<\/p><p>It happens thanks to the fact that massive stars often <a href=\"https:\/\/www.space.com\/22509-binary-stars.html\"><u>form in pairs<\/u><\/a>, and a star can sometimes survive the violent <a href=\"https:\/\/www.space.com\/6638-supernova.html\"><u>supernova<\/u><\/a> explosion that turns its companion into a black hole. When that happens, the two bodies continue to orbit each other. If such a duo aligns just right with Earth, the black hole will periodically pass directly between its companion <a href=\"https:\/\/www.space.com\/57-stars-formation-classification-and-constellations.html\"><u>star<\/u><\/a> and our planet. And when it does, the black hole's gravity acts <a href=\"https:\/\/www.space.com\/gravitational-lensing-explained\"><u>like a cosmic magnifying glass<\/u><\/a>, bending and magnifying the star's light, causing it to briefly appear brighter to watchful telescopes. <\/p><p>To find these hidden giants, the project relies on data from NASA's Transiting Exoplanet Survey Satellite, or <a href=\"https:\/\/www.space.com\/39939-tess-satellite-exoplanet-hunter.html\"><u>TESS<\/u><\/a>. Although the satellite's primary mission is to hunt for <a href=\"https:\/\/www.space.com\/astronomy\/exoplanets\"><u>planets beyond our solar system<\/u><\/a>, its method of data collection \u2014 tracking tiny, continuous changes in a star's brightness over time \u2014 is ideally suited for identifying black hole magnification events, the <a href=\"https:\/\/www.zooniverse.org\/projects\/cobalt-lensing\/black-hole-hunters\/about\/research\"><u>project description<\/u><\/a> notes.<\/p><p>\"It's a simple task with no expertise required,\" McMaster said in the statement. \"We will show volunteers examples of what to look for so all they have to do is recognise the right patterns.\"<\/p><p>Automated algorithms conduct a preliminary sweep of the TESS data, screening millions of potential stars for the most obvious black hole candidate locations, according to the project description.

Those measurements take time and are expensive, so a good shortlist helps researchers spend scarce telescope time wisely, the team says.<\/p><p>Since launching on the <a href=\"https:\/\/www.zooniverse.org\/projects\/cobalt-lensing\/black-hole-hunters\" ><u>Zooniverse platform<\/u><\/a> in October 2021, the project has attracted nearly 23,000 volunteers, who have completed more than 12 million classifications, according to its website.<\/p><p>Before turning to TESS, the team ran a similar search using data from SuperWASP, a ground-based survey that, like TESS, monitored stars for signs of planets from 2004 to 2016.
