Saturn is a planet that, like Earth, has an equinox. And this phenomenon recently occurred on the gas giant, accompanied by a unique event that offered a breathtaking spectacle.
It is important to note that Saturn has 274 known natural satellites, all of which vary in size. These satellites are also located at different distances from the planet, and some are even of interest to scientists because they could harbor some form of life.
However, our attention turns to Titan, which is none other than the largest of Saturn's natural satellites. It makes various transits, causing a gigantic shadow to appear on the surface of the planet.
And on Saturday, September 20, many amateur and professional astronomers around the world had the opportunity to observe a unique spectacle. Titan made its transit while the equinox took place on Saturn. In other words, it was possible to see a huge dark spot on the surface of this planet, while its rings were almost invisible from Earth.
This is a unique spectacle that only occurs once every fifteen years and could be observed around the world. And if you missed this opportunity, you will have to wait until 2040, even though Titan will make its last transit, which will be incomplete, on October 6. But be careful, because unpleasant surprises may occur between now and then and could spoil this event.
