    Magnetic fields may supercharge the sun’s release of heat

    Astronomers have linked flame-like tendrils rising from the sun to changes in its magnetic fields. This may be one step toward understanding why the sun’s corona is so very, very hot.

    A new, nonexplosive source of black holes?

    At least one black hole may have formed from the collapse of a cloud of gas, which is not the usual birthing scheme. This might even be how some of the earliest gargantuan black holes developed.
