Hubble's planetary portrait captures new changes in Jupiter's Great Red Spot

NASA/Goddard Space Flight Center

Scientists using NASA’s Hubble Space Telescope have produced new maps of Jupiter – the first in a series of annual portraits of the solar system’s outer planets. Already, the Jupiter images have revealed a rare wave just north of the planet’s equator and a unique filamentary feature in the core of the Great Red Spot not seen previously. The new images confirm that the Great Red Spot continues to shrink and become more circular, as it has been doing for years. Hubble will dedicate time each year to this special set of observations, called the Outer Planet Atmospheres Legacy program. The long-term value of the Outer Planet Atmospheres Legacy program is really exciting, said co-author Michael H. Wong of the University of California, Berkeley.
