Giant 'Cosmic Burger' Disk Challenges How Planets Form in Chaos

Astronomers have spotted a vast, turbulent disk where planets may be forming around a distant star—or possibly a pair of stars. Located roughly 1,000 light-years away, the structure is unlike any planetary system observed before. Its chaotic shape and sheer size have left researchers intrigued about how such systems evolve over time.

The disk, named IRAS 23077+6707, stretches nearly 400 billion miles across—about 40 times wider than our solar system. NASA's Hubble Space Telescope captured it almost perfectly edge-on, revealing a striking side profile. Seen this way, the disk resembles a giant cosmic 'burger' or 'macaron cookie', with a dark central band flanked by bright, glowing layers above and below.

What makes this disk unusual is its uneven, off-balance structure. Smoky wisps of material rise high above its surface, while long, thread-like filaments extend outward on one side. The disk's mass is estimated at 10 to 30 times that of Jupiter, suggesting enough raw material to form multiple gas giants. Its brightness and shape shift depending on the wavelength of light used to observe it. This variation hints at different types of dust scattered at varying heights within the disk. Despite its apparent maturity—no jets of material are shooting away from the system—it remains active and unstable. Scientists are uncertain whether it will eventually settle into a more orderly state. No other known planetary systems share these exact features. Telescopes like Hubble have yet to document anything quite like it, making IRAS 23077+6707 a unique case for studying how planets emerge from such chaotic environments.

The discovery offers a rare laboratory for understanding planet formation, particularly in extreme and turbulent conditions. Future observations will help determine whether the disk stabilises or continues its erratic behaviour. For now, its sheer scale and unusual structure provide astronomers with a new puzzle to explore.
