Two strange black spots gliding across Saturn’s rings have entered the field of view of NASA’s Hubble Telescope. The string is a sign that the planet is about to enter a new season.

Like Earth, Saturn is tilted on its axis and therefore has four seasons. Because Saturn’s orbit is much larger, each season on this gas giant lasts about 7 years. During the equinoxes, when the rings are tilted toward the Sun, mysterious dark (or light depending on the position of the observing device) spots often appear and appear to move along the rings, a phenomenon that astronomers cannot always tell. not explain with certainty.
NASA recently shared images and videos from the Hubble Space Telescope showing two blurry black dots sliding across Saturn’s B ring when this planet is about to approach autumnal equinox in the northern hemispherescheduled for May 6, 2025, CNN reported on February 13.
Saturn’s last equinox occurred in 2009, while NASA’s Cassini space probe was still orbiting the planet for close reconnaissance. As the Cassini mission ends in 2017, Hubble continues to monitor changes on Saturn and in worlds beyond Earth.

Ƭheo NASA, The dark spots become more visible as the autumnal equinox approaches and disappear as the summer or winter solstices approach Saturn.the time when the Sun reaches its highest or lowest latitude in the northern or southern hemisphere of the planet.
Although it is not clearly understood, astronomers suspect that these spots are caused by Saturn’s changing magnetic field. When the planet’s magnetic field interacts with the solar wind, it creates an electrically charged environment. Scientists believe that even the smallest ice particles (the size of a grain of dust) could be electrically charged, causing them to rise above the rest of the larger ice particles and rocks in the belt, thus creating obvious bulges.
Perhaps other ringed planets experience similar phenomena, but so far they have only been observed on Saturn’s dense, very prominent rings, according to Amy Simon, a senior planetary scientist at NASA.
