Thanks to a science competition Gadoury had won the previous year, the star pupil already had a relationship with the Canadian Space Agency. So when he asked if they could provide recent satellite imagery of the area that aligned with the constellation, they happily obliged.
According to the BBC:
He also scoured the internet for other satellite images from 2005, when a fire had engulfed the...
