Nearby Planetary System Seen in Breathtaking Detail A new Webb Space Telescope image of the bright, nearby star Fomalhaut reveals its planetary system with details never seen before, including nested concentric rings of dust. These belts most likely are carved by the gravitational forces produced b
This artist’s illustration depicts a collision of two icy, dusty bodies orbiting the bright star Fomalhaut, located 25 light-years away. This may have caused an expanding cloud of very fine dust particles. Astronomers using NASA’s James Webb Space Telescope have now discovered three nested debris belts surrounding the young star. These belts, which could be carved by the gravitational forces of unseen planets, provide insights into the structure of exoplanetary systems. Credit: ESA, NASA and M.
The belts encircle the young hot star, which can be seen with the naked eye as the brightest star in the southern constellation Piscis Austrinus. The dusty belts are the debris from collisions of larger bodies, analogous to asteroids and comets, and are frequently described as ‘debris disks.
The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky is flipped relative to direction arrows on a map of the ground . Fomalhaut’s dust ring was discovered in 1983 in observations made by NASA’s Infrared Astronomical Satellite . The existence of the ring has also been inferred from previous and longer-wavelength observations using submillimeter telescopes on Mauna Kea, Hawaii, NASA’s Spitzer Space Telescope, and Caltech’s Submillimeter Observatory.
