Astronomers using ESO’s Very Large Telescope found something they’d never seen before: a white dwarf, J1328−1450, wrapped in two rings of debris from planets that got torn apart when the star died, with a clean gap between them. The team thinks two surviving bodies, one maybe as big as Pluto, are herding that rubble into shape. The study is out this week in Nature Astronomy.
Why it matters
A white dwarf is what’s left when a Sun-like star burns out. That’s the long-range forecast for our own Sun, so this system is basically a preview of how a solar system ends. The researchers call it “a rare glimpse of the violent, chaotic process by which a planetary system meets its end.”
My take
Reading this, I couldn’t help thinking of Isaiah 51:6: “the heavens will vanish like smoke… But my salvation will last forever.” Stars die. Planets break. God doesn’t. “The heavens declare the glory of God” (Psalm 19:1), even when what they’re declaring is that this creation isn’t the last word. Peter says we’re looking forward to “a new heaven and a new earth” (2 Peter 3:13). That’s not a scary ending. That’s a promise.
God Bless, and May the Source Be with You!
