Astronomers observed a gamma-ray flare from a quasar — the ultra-bright core of a galaxy with a black hole inside. The light traveled for 7 billion years. Unexpectedly, it turned out to have originated not from the hole itself, but from the dust ring surrounding it. This helps us understand how blac

Earth's internal structure is traditionally studied using seismic methods and gravimetry. But neutrinos—particles that barely interact with matter—offer a fundamentally different, gentle probe. The IceCube collaboration analyzed 10.7 years of muon neutrino observations with energies from 500 GeV to
