    Quantum Physics

    Quantum mechanics means some black hole orbits are impossible to predict

    Computer simulations reveal that foreseeing the paths of three orbiting objects sometimes requires precision better than the quantum limit.

    Quasar winds with record energy levels were seen fleeing a distant galaxy

    The Hubble Space Telescope has seen the most energetic quasar winds yet, showing these active black holes can blow star-forming gas out of galaxies.

    A controversial X-ray glow didn’t show up in the Milky Way’s dark matter halo

    A new look at old data suggests that an odd X-ray glow that emanates from some galaxies cannot come from decaying dark matter.

    The star Betelgeuse might just be dusty, not about to explode

    A new study suggests that dust recently expelled by Betelgeuse is why the star dimmed suddenly in late 2019 before brightening again.

    A black hole eruption marks the most powerful explosion ever spotted

    Hundreds of millions of years ago, a black hole blasted out roughly 100 billion times as much energy as the sun is expected to emit in its lifetime.

    50 years ago, scientists were studying why the sun’s corona is so hot

    In 1970, scientists were hoping to learn why the sun’s corona is so hot during an eclipse. Fifty years later, the corona’s magnetic field may hold some answers.
