Observing the elegance of a star's demise, the JWST offers a tantalizing glimpse into the fate of our solar sun
News Article: JWST Reveals Binary Star System at Heart of NGC 6072
NASA's James Webb Space Telescope (JWST) has unveiled a stunning portrait of the dying star NGC 6072, located 3,060 light-years away in the constellation of Scorpius. The telescope's detailed images reveal a complex and chaotic structure, providing evidence for the presence of two stars at the heart of the planetary nebula.
The JWST's Mid-Infrared Instrument (MIRI) has captured a series of concentric rings radiating out from the center of the nebula, which could be evidence for a second star. These rings are believed to be caused by the second star cutting through the material being ejected, or by a series of pulsations within the dying star that take place every few thousand years.
The JWST's images highlight the beauty and unusual nature of dying stars, and foreshadow the future of our own sun in about five billion years. The telescope's Near-Infrared Camera (NIRCam) reveals multiple pairs of outflows coming from the dying star and pointing in various directions within NGC 6072. One outflow is visible from the 11 o'clock to the 5 o'clock position in the image.
The clumps of gas and dust in the image of NGC 6072 are painted dark orange, indicating that the central star has shed up to 80% of its total mass. Relatively empty, dust-free regions in the image appear blue. Dense patches of molecular hydrogen gas in the nebula are shielded from the white dwarf's harsh ultraviolet light by veils of thick dust, causing clumpiness.
Gaia's observations suggest there are not just one but two stars at the heart of NGC 6072. Despite the JWST's high resolution, it cannot resolve the companion star if it is very close to the dying star. The changing direction of outflows in NGC 6072 is a result of gravitational interactions between the dying central star and its companion star.
The more massive of the two stars in NGC 6072 experienced a stutter in its nuclear furnace tens of thousands of years ago. The energy from these reactions allowed the outer layers to eject themselves from the star, forming the nebula. The exposed gas around these clumps is being ionized by the ultraviolet light from the white dwarf.
Another outflow can be seen from 1 o'clock to 7 o'clock, and there's a possible third outflow that appears vertical in the image, from 12 o'clock to 6 o'clock. The evidence for the presence of two stars at the heart of the planetary nebula NGC 6072 primarily comes from detailed observations by the Gaia mission and is strongly supported by new images from the JWST.
These groundbreaking discoveries showcase the power of space telescopes like the JWST in unlocking the mysteries of the universe. As we continue to explore the cosmos, we gain a deeper understanding of the life cycles of stars and the complex interactions that shape the celestial bodies we observe.
The science community is abuzz with news about the discovery of a binary star system at the core of NGC 6072, thanks to NASA's James Webb Space Telescope (JWST). The advancement in technology, embodied by the JWST's Mid-Infrared Instrument (MIRI) and Near-Infrared Camera (NIRCam), have enabled scientists to uncover previously undetected features in space-and-astronomy.
