    Explainer: Stars and their families

    Most pinpoints that light the night sky are raging infernos we call stars. As adults, many will create new elements that they later cast off into the cosmos.

    Spotted: Milky Way’s giant gas bubbles in visible light

    The bubbles have different colors, based on how the gas inside them moves. That could give clues to how the bubbles developed.

    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.

    Sun’s nearest stellar neighbor may have Earth-like planet

    A planet roughly the size of Earth orbits within the “Goldilocks” zone of the Proxima Centauri. Only 4.2 light-years away, this star is the one closest to our sun.

    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.
