Hubble Reveals 400-Billion-Mile Planet-Forming Disk With One-Sided Filaments

IRAS 23077+6707, about 1,000 light-years away, is the largest known protoplanetary disk, and Hubble’s visible-light images show it is unusually chaotic and lopsided.
400 billion miles across—about 40 times wider than the solar system out to the Kuiper Belt—the disk shows huge wisps of gas and dust above and below it, with the longest filaments visible on only one side.
Researchers say the asymmetry may reflect fresh material falling into the disk or interactions with its surroundings, offering a rare view of active processes in planet formation.
The system holds an estimated 10 to 30 Jupiter masses of material, enough to potentially build several giant planets and making it a new laboratory for studying how planetary systems form in extreme environments.

What cosmic forces are sculpting the bizarre, lopsided structure of the universe's largest known planet nursery?
Unveiling "Dracula's Chivito": How the Largest Known Planet-Forming Disk Is Rewriting the Rules of Planetary Birth
Overview
The astronomical community has made a groundbreaking discovery with IRAS 23077+6707, known as "Dracula's Chivito." This vast, swirling disk of dust and gas is the largest planet-forming disk ever observed, with a young star deeply hidden inside thick clouds. Scientists are intrigued by the mystery at its center, which could be a single massive star or a binary system. Its unusual size and strange features set it apart from other celestial objects, offering new insights into how stars and planets form in the universe.
