PULSARS CREATE ANTIMATTER? GEMINGA REVEALS THE TRUTH

Ajouté : 2026-05-01

[00:00:00]A mysterious glow in space may explain antimatter near Earth. It comes from a [music] pulsar, a rapidly spinning neutron star, the dense remnant of an exploded star. One of them is called Geminga. NASA's Fermi telescope has studied it for over a decade. Now, the data reveals something new, a vast halo of gamma rays surrounding the pulsar, faint but enormous. When scientists remove background noise, this halo becomes visible and it tells a story, a story about positrons, the antimatter version of electrons. These particles exist near [music] Earth, but their origin was unknown until now. The halo around Geminga matches computer models, models that explain how positrons are created. This confirms a long-held idea.

[00:00:54]Pulsars are a major source of antimatter. In fact, Geminga alone may produce a significant portion, up to 20% of high-energy positrons detected near Earth. This changes how we see pulsars.

[00:01:10]They don't just emit extreme radiation, they also generate antimatter, invisible yet measurable, a hidden connection between distant stars and our own planet, and another step closer to understanding the universe.
