In the quiet, cold expanse of space, a remarkable and deliciously shaped cosmic object is challenging our understanding of how planetary systems come to be. Astronomers have turned their gaze toward IRAS 23077+6707, a young star system viewed edge-on from Earth, and what they see is a colossal, messy, and awe-inspiring protoplanetary disk—the birthplace of planets—that bears an uncanny resemblance to a hamburger.
Owing to its unique structure, it has earned a playful, if ominous, nickname: “Dracula’s Chivito.” For the uninitiated, a chivito is the national sandwich of Uruguay, a hearty stack of ingredients. In this case, the "buns" are the bright, scattered light from the disk's surfaces, and the "patty" is the dark, dense lane of dust and gas blocking the central star from view. It’s a fitting name for a object that is both fascinating and a little monstrous in scale.
A Colossal Planetary Nursery
Located roughly 1,000 light-years away, this celestial deli sandwich is anything but bite-sized. The disk spans a staggering 400 billion miles—about 40 times the diameter of our solar system out to the Kuiper Belt. Within this vast swirling cloud of material, astronomers estimate there is enough mass to forge 10 to 30 Jupiter-sized planets. It’s a veritable factory for potential gas giants.
The discovery, detailed in a recent study in The Astrophysical Journal, is turning heads not just for its shape, but for its surprising and chaotic structure.

Chaos in the Cradle
What truly sets Dracula’s Chivito apart is its striking asymmetry. One side of the disk exhibits long, filament-like features streaming away from the central lane, while the other side appears comparatively smooth and clean. This lopsidedness hints at a dynamic and turbulent environment.
Researchers suggest this imbalance could be caused by new material, like dust and gas, still falling into the disk from its surrounding molecular cloud. Alternatively, the external environment of space itself—perhaps the gentle pressure of interstellar winds or the gravitational influence of a distant passing object—could be sculpting one side of the disk.
Adding to the chaotic scene are wispy, layered structures within the disk itself. These features suggest this is not a calm, orderly rotating platter of dust, but an active and violent construction zone. As one of the researchers noted, this is "the largest chaotic birthplace of planets we've ever witnessed."
NASA’s Hubble Space Telescope has previously revealed the chaotic nature of such massive disks. To see how this discovery fits into a larger picture of turbulent planet formation, explore this related feature from NASA: NASA’s Hubble Reveals Largest Found Chaotic Birthplace of Planets.
More Questions Than Answers
“We have simply never seen anything quite like this in other, similar systems,” explained the lead author of the study. The peculiar asymmetry and complex layers have left astronomers with more questions than definitive answers. Is this how all massive planetary systems begin? Or is IRAS 23077+6707 a unique cosmic oddity?
Further observations, particularly with powerful instruments like the James Webb Space Telescope, will be crucial. By peering through the dust in infrared light, scientists hope to understand the chemistry and dynamics at play. This data could unlock profound insights into how planets form over time and how the process differs in various stellar environments.
Witnessing Cosmic History
The study of objects like Dracula’s Chivito is more than cataloging celestial curiosities; it’s a direct look into our own origins. Our solar system began in a similar, though perhaps less chaotic, disk of gas and dust over 4.5 billion years ago. By observing these distant, young systems, we are effectively watching the history of our own cosmic neighborhood play out in real-time.
For astronomy enthusiasts eager to explore the cosmos from their backyard, having the right equipment is key. A good starter telescope can bring the wonders of star and planet formation into clearer view. You can find excellent options for beginning this journey here: Beginner Telescopes on Amazon.
The discovery of IRAS 23077+6707 reminds us that the universe is both wonderfully familiar—shaping something as simple as a sandwich—and profoundly mysterious, holding chaotic secrets about the birth of worlds. As astronomers continue to study this cosmic hamburger, we await the next chapter in understanding where planets, and ultimately, we, come from.
