Astronomers have found a ' Peter Pan' disk around a low-mass star that has a life span of 30 million years .
The disk is rich in hydrocarbons, with chemical signatures never seen before in such a dated disk.
This extended lifetime could have important implications for planet formation.
The presence of argon and neon atomic lines suggest soft X-rays and extreme ultraviolet rays may be responsible for ionizing the disk.
Giant planets are thought to form within the first few million years because they require a large amount of gas.
But if the gas sticks around for longer timescales, that may allow more time for giant planets to be built.
Carbon-rich disks may be a signature of long-lived disks around low-mass stars.
