The search is on for an elusive particle that could shine a light on the "dark sector"—the vast majority of the universe that we cannot see.
Particle accelerators speed up elementary bits of matter to probe fundamental questions in physics, however, current facilities require huge amounts of space.
The finding shines new light on our understanding of the cosmos.
As one astronomer put it: "Wow!"
NASA's 2019 budget proposal calls for the telescope to be canceled "due to its significant cost and higher priorities within NASA."
A new theoretical model of dark matter suggests it contains two distinct varieties of charged particles, which would allow it to form compact objects.
