When their end comes, the stars will explode in a blast making them around 200,000 times brighter than Jupiter does now.

In recent years, one of the most troubling puzzles in astrophysics has grown more urgent. Scientists have realized that the ...

If dark matter is creating positrons in the CMZ, those particles will eventually slow down and eventually annihilate with electrons in the environment, producing gamma-rays at exactly 511keV energy.
