Hubble Spots Largest Planet-Forming Disk Ever Seen

Scientists just discovered a cosmic sandwich that could reshape our understanding of how planets are born.

The Hubble Space Telescope captured stunning images of IRAS 23077+6707, the largest planet-forming disk ever observed around a young star. Located 978 light-years away in the constellation Cepheus, this massive structure spans nearly 400 billion miles, more than 100 times the diameter of our inner solar system.

Astronomers nicknamed it "Dracula's Chivito" as a playful nod to both its layered, sandwich-like appearance and its discovery team. The researchers hail from Transylvania, Romania (fictional home of Dracula) and Uruguay, where the national dish is the chivito, a stacked sandwich that mirrors the disk's layers of gas and dust.

These protoplanetary disks are where magic happens in space. Rich in gas and dust, they're the cosmic nurseries where both rocky planets like Earth and gas giants like Jupiter take shape around young stars.

What makes this discovery especially exciting is how wild and unpredictable the disk appears. Bright wisps of material shoot far above and below the main disk, defying the neat, orderly structures scientists expected to see.

"The level of detail we're seeing is rare in protoplanetary disk imaging," said Kristina Monsch, an astronomer at the Harvard and Smithsonian Center for Astrophysics who led the research. The system shows bright, vertically stretched filaments of gas on only one side, while the opposite side has a sharp edge, creating a lopsided structure that puzzles researchers.

Why This Inspires

This discovery reminds us that the universe still holds countless surprises waiting to be found. Every time we point our telescopes skyward, we learn that nature is far more creative and complex than our theories predict.

The chaotic beauty of this planet-forming disk suggests that solar systems might develop in many more ways than we imagined. That means the potential for diverse planetary systems, and perhaps life itself, could be even greater than we dared to hope.

"Hubble has given us a front row seat to the chaotic processes that are shaping disks as they build new planets," said co-investigator Joshua Bennett Lovell. These processes remain mysterious, but now scientists can study them in unprecedented detail.

This massive cosmic sandwich could theoretically contain a vast planetary system in the making. Somewhere in those swirling layers of gas and dust, worlds may be taking their first steps toward existence.
