Saturn

The 366 exoplanets were found by an algorithm that searched 800 million images of stars taken by NASA's Kepler Space Telescope in its K2 mission.

Stargazers are also being treated to the sight of the moon approaching and then bypassing each of the three planets this week.

The ringed gas giant put on a show for Earth this week, in a treat for astrophotographers who took to social media to share their images.

Saturn experiences seasons just like the Earth, although they last for significantly longer than those on our planet.

The event follows the conjunction of Jupiter and Mercury, which aligned on the morning of Friday March 5.

This type of moon marks the start of the winter astronomical calendar.

The gas giants appeared to come closer than they had done for almost 400 years on Monday, days before Christmas.

Jupiter and Saturn are set to appear close together in the sky in a major celestial event known as the Great Conjunction.

This year's December solstice will coincide with the bright planets forming what has been dubbed a "Christmas star."

Saturn and Jupiter will be at their closest for 400 years on December 21.

Great conjunctions of Jupiter and Saturn are rare, occurring once every two decades or so.

In the Northern Hemisphere, the September equinox marks the beginning of what's set to be quite an eventful astronomical fall.

Two of Saturn's many moons, Mimas and Enceladus, can be seen in the Hubble image.

If you want to see the spectacle, you will need to head outside around an hour before sunrise on Sunday.

The finding could shed light on the long-debated issue of when Saturn's rings and moons formed.

Meteor showers are celestial events in which several shooting stars appear to originate from a single point in the sky.

Data from the Cassini mission have revealed molecules in ice grains emanating from the icy, water-rich world.

Titan, Saturn's largest moon, is covered in lakes filled with liquid hydrocarbons, such as methane and ethane.

Before its mission ended in September 2017, NASA's Cassini probe conducted a series of dives between Saturn's cloud tops and its rings.

NASA's James Webb Telescope will open up an entirely new avenue for searching for extraterrestrial life.

Data from Cassini's "death dive" reveals Saturn's rings could be just 10 million years old.

Planet is losing mass from its rings at the maximum rate predicted, the space agency finds.

Full alignment will be easier to see from the Southern Hemisphere—but people at Northern latitudes should still be able to spot Mars, Saturn and Jupiter.

These ancient rocks are relics of the early solar system.

Here's the real thing.

Binoculars or a telescope might be necessary to see some of the planets.

The hexagon is essentially a swirling system of air currents and turbulent weather that has lasted for decades.

The moon will come within four-moon diameters of Saturn in the night sky.

Some of the most stunning photos of the planets and moons in our solar system, including our own.

The distinctive shape may have been the natural result of head-on collisions between smaller moonlets.
