  1. 💁🏻‍♀️ TIL: ☀️🌍 For decades, scientists assumed #Earth would spiral into the #Sun when it swells into a red giant billions of years from now.

    A new study flips that prediction. Better modeling of tidal dissipation inside dying #stars finds that the Sun’s mass loss from stellar wind may push Earth outward, potentially saving it from incineration.

  3. Beautiful new cover at Nature Astronomy's

    Concentric shells of highly ionized calcium and sulfur in the ejecta of a type Ia supernova provide evidence of the double-detonation scenario for exploding sub-Chandrasekhar-mass white dwarfs.
