Two enormous gamma-ray bubbles, stretching 50,000 light-years, have been discovered above and below the Milky Way. Their distinct high-energy emissions and sharp edges suggest a powerful, sudden event in our galaxy's past, possibly linked to its central supermassive black hole.
Scientists have long debated the origin of the giant gamma-ray-emitting Fermi bubbles above and below the Milky Way. While a supermassive black hole was the leading suspect, new simulations suggest supernovae activity alone might be responsible, reopening the mystery.
Astronomers are exploring the possibility of building Dyson spheres around compact white dwarf stars, which offer a long-lasting and stable energy source. Meanwhile, the Vera Rubin Observatory promises near real-time astronomical discovery, and new data challenges models of supermassive black hole formation in the early universe.
