Saturn’s moon Pan:  Here’s Our Best Look Yet at Saturn’s ‘UFO’ Moon


There’s a tiny “flying saucer” orbiting deep within Saturn’s rings, and a NASA probe has just gotten its most impressive look yet at the strange object.

The saucer is actually a little moon called Pan, and NASA’s Cassini spacecraft captured its distinctive shape on March 7 in a stunningly detailed series of images.

Named for the flute-playing Greek god of wild places, 21-mile-wide Pan is what’s called a shepherd moon. It lives within a gap in Saturn’s A ring, which is the farthest loop of icy particles from the planet.

“The shape, as others have also pointed out, is probably because it is always sweeping up fine dust from the rings,” Showalter explains. “The rings are very thin compared to the size of Pan, so the dust accumulates around its equator.”

Pan isn’t alone in its bizarre appearance: Another small moon, Atlas, bears a similar shape for similar reasons.

And on a different scale: Hubble Showcases a Remarkable Galactic Hybrid

A remarkable galactic hybrid

 This NASA/ESA Hubble Space Telescope image showcases the remarkable galaxy UGC 12591. UGC 12591 sits somewhere between a lenticular and a spiral. It lies just under 400 million light-years away from us in the westernmost region of the Pisces–Perseus Supercluster, a long chain of galaxy clusters that stretches out for hundreds of millions of light-years — one of the largest known structures in the cosmos.

The galaxy itself is also extraordinary: it is incredibly massive. The galaxy and its halo together contain several hundred billion times the mass of the sun; four times the mass of the Milky Way. It also whirls round extremely quickly, rotating at speeds of up to 1.8 million kilometers (1.1 million miles) per hour.

Observations with Hubble are helping astronomers to understand the mass of UGC 12591, and to determine whether the galaxy simply formed and grew slowly over time, or whether it might have grown unusually massive by colliding and merging with another large galaxy at some point in its past.

    cool pix.. BUT ‘how bizarre’ 😀

  2. The more we get to see of space the more ‘bizarre’ things look. When you look at how diverse things are just here on Earth it shouldn’t be surprising.

      Pan looks like its spewed out a ring of either: Lava or is it ‘plastic’ ? 😀

        The first one looks as like a photo of a squashed plastic ball.The dog once had one that wasn’t meant for terrier teeth and ended up looking like this, to his great surprise.

          It also looks like the ghastly, naff, many decades out of fashion-where did the school find them ?-fake Panama hats that we had to wear at school, after we’d done what we could to squash and distort the things in the hope that the school would get the message.
