Hubble Spots Giant, Turbulent Planet-Forming Disk 40 Times Wider Than Our Solar System

NASA’s Hubble Space Telescope has captured the largest known protoplanetary disk around the young star IRAS 23077+6707 (nicknamed Dracula’s Chivito), extending about 400 billion miles—roughly 40 times the Solar System’s diameter. Seen nearly edge-on in visible light, the disk is unusually turbulent and asymmetric, with filament-like features on one side and a sharp edge on the other, hinting at dynamic infall of material and environmental interactions. With an estimated mass 10–30 times Jupiter’s, the system may host a large planetary system and provides a valuable laboratory for understanding planet formation in extreme conditions.

JWST traces crystal seeds from a newborn star to its outer disk

NASA’s James Webb Space Telescope mapped where crystalline silicates form around the young star EC 53 in the Serpens Nebula and showed these minerals being carried outward by winds into the outer, planet-forming disk. EC 53 undergos ~18-month bursts lasting about 100 days, forging silicates in hot regions and launching them into cooler outer regions, effectively seeding the outer disk with components that icy comets may carry—providing a direct link between crystal formation and distribution in early planetary systems. The findings, published in Nature, help explain how comets at the solar system’s edge could form.

Webb Discovers Crystalline Silicates Forged in Inner Disk of Young Star, Flung to Disk Edges

NASA’s James Webb Space Telescope observed protostar EC 53 in the Serpens Nebula and confirmed that crystalline silicates form in the hot inner disk, with MIRI spectra identifying minerals like forsterite and enstatite. The star’s strong disk winds and periodic outbursts appear to launch these crystals outward toward the disk’s edges, offering a mechanism for crystalline silicates found in comets and potentially seeding planet formation during the system’s ongoing evolution.

Cosmic Hamburger Disk Reveals Birthplace of Distant Giant Planets

Astronomers using ALMA have imaged Gomez’s Hamburger (GoHam), one of the largest edge-on protoplanetary disks, finding a stratified arrangement of gas and dust and signs of ongoing planet formation, including a potential giant-planet core or clump dubbed GoHam b in the outer disk. The disk’s sheer size and uneven features—such as a bright, lopsided region and a northern wind—make it an ideal laboratory to study how giant planets can form far from their star and how such planets shape their surroundings.

Hubble Unveils the Largest and Most Chaotic Planet Nurseries

Astronomers have captured the first visible-light image of 'Dracula’s Chivito,' the largest and most chaotic planet-forming disk ever observed, located about 1,000 light-years away. This massive, asymmetric disk exhibits unusual features like extended filaments on one side, challenging previous assumptions about the serenity of planet nurseries. It serves as a scaled-up model of early solar system conditions, offering new insights into the complex processes of planet formation.
