PARIS: Cleo Loi is only 23 years old, but the University of Sydney student of astrophysics–undergrad, even—has just proven something that scientists couldn’t for the past 60 years.
The theory was that there might be enormous bodies of plasma moving about Earth in a series of rings aligned with our magnetic poles, though none could prove it.
Ms. Loi, however, had the ingenious idea of splitting the actions of a radio telescope array in half. By using the left half to look slightly to the right, and the right half to look slightly to the left, she was able to essentially mimic the triangulation that human eyes use to determine depth and see in three dimensions. The result: She and her research team found the plasma rings.
