If you don't own an Apple device, you can still use our Saturn satellites predictor to create a map of all of Saturn's moons that are visible in amateur telescopes at any date and time. The reason for their differences is unknown. $fancy.scrolling = "none"; 0000001576 00000 n The Voyager and Pioneer flybys of the 1970s and 1980s provided rough sketches of Saturn’s moons.

P.K. This site is maintained by the Planetary Science Communications team at. On the moon Tethys, Cassini observed mysterious red arcs, though they weren’t easy to see. Cassini looked, listened, sniffed and even tasted Saturn’s moons, and what it learned about them is nothing less than extraordinary. Didymos B is getting an official name of its own: Dimorphos. Fun — and even educational — NASA activities to do at home. A team has found 20 new moons orbiting Saturn. 0 ��[ if(isFancyboxOpen) { Cassini also found thin atmospheres around the moons Dione and Rhea—but we’re talking thin, around 5 trillion times less dense than at Earth’s surface. 0000037920 00000 n } In the infrared, the red arcs are obvious, as if someone dragged a giant red crayon across the surface of a golf ball. %%EOF J.

Cassini also solved the centuries-old puzzle about why the moon Iapetus has one snow-white hemisphere while its other hemisphere is nearly as dark as charcoal.

0000012537 00000 n Hyperion can’t boast any sort of atmosphere, but the tumbling, sponge-looking moon does build up a static charge, which scientists realized when Cassini passed through a beam of electrons coming up from the moon’s surface. 0000000016 00000 n 0000010715 00000 n This image of Saturn was taken by NASA's Hubble Space Telescope on July 4, 2020, when the planet was 839 million miles from Earth.

Some small moons are trapped in the same orbits as Tethys or Dione. 0000021727 00000 n Titan is the only known world other than Earth where any sort of liquid collects on its surface. x�b``�a``sb`d`X�����X�X8/`Xπ% Whether you're doing it for the nerd cred or the pie, this week on #10Things, we've got all the ways you can celebrate #PiDay with NASA. Now more and more Cassini data indicates that Enceladus is home to a global (not just regional) ocean, and the jets near the south polar region are powered by hotspots, where heat from the interior ocean escapes. The evidence is beginning to pile up that Enceladus might have hydrothermal vents too. 0000002515 00000 n Doing so bought Cassini time—more than a decade—to linger and watch Saturn’s exotic zoo of 60-plus moons like no spacecraft before. One object observed in the rings (and unofficially called Peggy) may be a moon forming or disintegrating, or it might not truly be a moon at all.

Made of a pair of two-wheeled vehicles, DuAxel is designed to descend craters and near-vertical cliffs on the Moon, Mars, and beyond. The next full Moon will be early Sunday morning, July 5, 2020. the opposite way to the other moons. But during its many years in Saturn orbit, NASA’s Cassini spacecraft discovered previously unknown moons, solved mysteries about known ones, studied their interactions with the rings and uncovered new mysteries—including the discovery on an ocean moon with potential ingredients for life—that will engage a whole new generation of space scientists. Seidelmann. The next full Moon will be midday on Monday, August 3, 2020. 0000002654 00000 n 147 0 obj<>stream startxref It turns out that dark material falls on Iapetus’s leading side. Phillips Davis Mimas and Enceladus are the same size,” Spilker said, but Enceladus has water jets while Mimas appears not to.

Even if Enceladus isn’t home to even simple organisms, the presence of the necessary conditions is itself a remarkable finding.
