NASA’s James Webb Space Telescope has imaged the Lion’s Head Nebula, a planetary nebula formed by the remnant of a Sun-like star.
Key facts
- •The Lion’s Head Nebula is cataloged as NGC 2392.
- •The image was created using the JWST's NIRCam and MIRI instruments.
- •The nebula is the result of a star that could no longer maintain nuclear fusion.
- •A white dwarf star remains at the center of the nebula.
- •The nebula's structure is shaped by ionizing radiation from the central white dwarf.
The James Webb Space Telescope (JWST) has captured a new composite image of the Lion’s Head Nebula, also known as NGC 2392. Using its NIRCam and MIRI instruments, the telescope provided a detailed view of the nebula, which is the remnant of a star similar to the Sun.
Formation of the Nebula
The nebula formed after a Sun-like star could no longer sustain the nuclear fusion required to remain stable. As a result, the star began shedding layers of gas and dust into space, creating the planetary nebula observed today. At the center of the structure, located within the 'lion's nose,' lies a hot stellar core known as a white dwarf.
Structure and Scientific Value
The nebula's irregular bubble-like appearance is caused by intense radiation from the white dwarf, which ionizes the expanding gas. The 'lion's mane' is composed of a cloud of ionized gas and dust clumps that have resisted the radiation. This detailed imagery is expected to assist researchers in understanding the interactions between gas, dust, and white dwarf radiation.
