Scientists build a model of Saturn’s interior: thick helium rain layer may affect the planet’s magnetic field
On the evening of November 19th, the night sky showed Jupiter and Saturn”double stars with the moon” astronomical phenomenon. Because Jupiter and Saturn revolve around the sun in a relatively different cycle, about every 20 years, there is a chance to appreciate the”wood-earth conjunction” scene.

Jupiter and Saturn will participate in this double moon companion moon. Hurry up and set the alarm clock and go to the western night sky to take a look! In Kunming, when the evening sky fades, the Jupiter moon will be in the southwest sky at around 18:35. Appears at 37° elevation angle.
