They discover a “ghostly” phenomenon in Saturn's rings

Clear images from the Hubble Space Telescope show that the frequency of radio appearances on Saturn is seasonal.

Data from the Hubble Space Telescope captured an image of Saturn when the planet was about 1,365 million kilometers from Earth. Very sharp vision reveals a A “ghostly” phenomenon in the rings Known as radios.

The snapshot, released by NASA and the European Space Agency (ESA) on December 21, 2023, is dated October 22.

Saturn's magnifiers are fleeting features that orbit with the rings and have only a “ghostly appearance.” It continues for two or three cycles About Saturn, report separate data from the European Space Agency and NASA.

In 1981, NASA's Voyager 2 spacecraft took photos First time speaker of the rings The Cassini spacecraft also observed them during its 13-year mission that ended in 2017.

Hubble continues to observe Saturn annually as radios come and go. This cycle was captured by Hubble's OPAL program, which began nearly a decade ago to observe the planets annually Climate changes on planets Offshore gas giants.

Their clear photos show that frequency Radio appearances are seasonal.

Long-term observation shows that both the number of rays and their contrast They vary with Saturn's seasons. The planet is tilted on its axis like Earth, and it has seasons that last about seven years.

“We are heading towards the Saturnian equinox, where maximum radio activity is expected, in the coming years The radii will appear darker “And more frequently,” explains OPAL principal scientist Amy Simon of NASA's Goddard Space Flight Center in Greenbelt, Maryland.

This year, these ephemeral structures appear on both sides of the planet simultaneously as they orbit the giant globe. Although it appears small compared to Saturn, its length and width can extend More than the diameter of the Earth.

There are many theories – the main one being that the speaker is connected to the interactions between The strong magnetic field of Saturn and the SunBut after several decades, no one fully predicted this phenomenon.

Ongoing observations by Hubble, a NASA/ESA project, may help solve the mystery.
