The tiny microquasar Cygnus X-3 — like a blacksmith's forge — accelerates protons to energies billions of times greater than the Large Hadron Collider can achieve. These particles, escaping into space, form a gigantic gamma-ray halo comparable in size to an entire constellation. Someday, by learning to read such traces, we will be able to map the invisible "hearts" of the Galaxy — and perhaps come closer to unraveling the origin of the most energetic cosmic rays.
🎯 The energy of a single 10 PeV proton is comparable to that of a flying mosquito, but squeezed into a subatomic volume. And Cygnus X-3 itself is so bright in radio waves that it's sometimes called a "mini-quasar" — like a real quasar, only in our own Galaxy.
🎬 The idea that microquasars can serve as natural accelerators echoes the concept of "wormholes" or sci-fi engines that use relativistic jets for interstellar travel — except here the jets aren't carrying a ship; they're birthing particles that pierce the Galaxy.
