Cassini has sent back images from its second stunning dive through Saturn's rings. And they're even more beautiful and eerie than before.

The dive was one of 22 journeys the spacecraft is making through the rings as part of its "Grand Finale". That will end in September when engineers fly the craft into Saturn's atmosphere and destroy it — necessary to ensure that any life that attached itself to Cassini doesn't populate other worlds.

But before its fiery end, Cassini is going to send back some of the best pictures we have ever seen of Saturn and its stunning rings. And the new images more than fulfil that brief.

The false-color image of the storm resembles a red rose surrounded by green foliage which was made by using a combination of spectral filters sensitive to wavelengths of near-infrared light at a distance of approximately 261,000 miles from Saturn NASA via Getty Images Cassini's mission to Saturn The planet Saturn is seen in the first color composite made of images taken by NASA's Cassini spacecraft on its approach to the ringed planet, October 21, 2002. The probe's arrival is still 20 months away. The planet was 285 million kilometers (177 million miles) away from the spacecraft, nearly twice the distance between the Sun and Earth, when Cassini took images of it using various filters NASA/Getty Images Cassini's mission to Saturn Nasa's Cassini spacecraft is shown diving through the plume of Saturn's moon Enceladus in 2015 Nasa/JPL-Caltech/Reuters Cassini's mission to Saturn NASA's Cassini spacecraft captured this view of planet Earth as a point of light between the icy rings of Saturn NASA/JPL-Caltech/Space Science Institute Cassini's mission to Saturn The giant plumes of ice on Enceladus seen by the Cassini spacecraft in 2009 Nasa Cassini's mission to Saturn The image of Titan is actually a composite of a number of pictures taken by Cassini during the flyby Cassini's mission to Saturn The unique six-sided jet stream at Saturn's north pole known as "the hexagon" taken by NASA's Cassini mission is seen in this still handout image from a movie released December 4, 2013. The movie, made from images obtained by Cassini's imaging cameras, is the first to show the hexagon in color filters, and the first movie to show a complete view from the north pole down to about 70 degrees north latitude.

The glint off a mirror-like surface is known as a specular reflection. It confirmed the presence of liquid in the moon's northern hemisphere, where lakes are more numerous and larger than those in the southern hemisphere.

They show the stunning, streaking rings that surround Saturn in unprecedented detail.

The images were taken when Cassini dived into the mysteriously and shockingly empty space between Saturn and its rings, during a flyby on 2 May. The ship has been sending back the raw images from that journey since.

Nasa expects the images will get better over time, as engineers learn more about how best to use the cameras that are mounted onto Cassini.

"The images from the first pass were great, but we were conservative with the camera settings. We plan to make updates to our observations for a similar opportunity on June 29 that we think will result in even better views," said Andrew Ingersoll, a member of the Cassini imaging team based at Caltech in Pasadena, California.

Nasa also released a video made up of the images that were taken on Cassini's first big dive.
