May as well put this here too.Went to the Mt Wilson Observatory, saw a few things through the 60" telescope. Saw Jupiter, Mars, Saturn, the entire Sombrero galaxy (M104), a globular cluster (M3), and the Cat's Eye nebula.
Only Saturn seemed like it would turn out well on my point-and-shoot, so it's the only one I attempted (camera held right up to the eyepiece). It looked much more distinct in person, I could see streaks on its surface and a black band separating the sections of the rings. Seeing Sombrero was the most impressive - an entire galaxy in the view of my puny eye.

Mysterious 'magic island' appears on Saturn's moon Titan
Now you don't see it. Now, you do. And now you don't see it again. Astronomers have discovered a bright, mysterious geologic object -- where one never existed -- on Cassini mission radar images of Ligeia Mare, the second-largest sea on Saturn's moon Titan. Scientifically speaking, this spot is considered a "transient feature," but the astronomers have playfully dubbed it "Magic Island."Reporting in the journal Nature Geoscience June 22, the scientists say this may be the first observation of dynamic, geological processes in Titan's northern hemisphere. "This discovery tells us that the liquids in Titan's northern hemisphere are not simply stagnant and unchanging, but rather that changes do occur," said Jason Hofgartner, a Cornell University graduate student in the field of planetary sciences, and the paper's lead author. "We don't know precisely what caused this 'magic island' to appear, but we'd like to study it further."

Swirling Cloud at Titan's Pole is Cold and Toxic
Scientists analyzing data from NASA's Cassini mission have discovered that a giant, toxic cloud is hovering over the south pole of Saturn's largest moon, Titan, after the atmosphere there cooled dramatically.The scientists found that this giant polar vortex contains frozen particles of the toxic compound hydrogen cyanide, or HCN.

Cassini Caught in Hyperion's Particle Beam
Static electricity is known to play an important role on Earth's airless, dusty moon, but evidence of static charge building up on other objects in the solar system has been elusive until now. A new analysis of data from NASA's Cassini mission has revealed that, during a 2005 flyby of Saturn's moon Hyperion, the spacecraft was briefly bathed in a beam of electrons coming from the moon's electrostatically charged surface.The finding represents the first confirmed detection of a charged surface on an object other than our moon, although it is predicted to occur on many different bodies, including asteroids and comets.

"...picture taken of a comet from the Rosetta probe." As shared by an fb friend. I didn't know the probe was going to land on Rosetta (iow, not sure what I'm looking at here).

that's the "neck" of the comet, seen at a distance of something like 7km. rosetta is orbiting increasingly closer and will deploy the landing probe (a separate craft) in a few weeks.
― sleepingsignal, Saturday, 25 October 2014 01:40 (nine years ago) link
I was wondering about that object in the distance, I couldn't tell if that was just a longer view of the same shot, superimposed on the close-up, or a separate entity.
― nickn, Saturday, 25 October 2014 03:01 (nine years ago) link
that's the "head", attached to the part in the foreground. there are plenty of images of the comet in its entirety showing the odd shape.
― sleepingsignal, Saturday, 25 October 2014 04:16 (nine years ago) link
OK, I see it now, it looked like a separate object. I posted pictures Aug 7, and I think I can tell the angle this latest shot was taken from in it (upper right looking down).

xp I have that one saved and sometimes I just break it out and stare at it. In the words of Nigel Tufnel, "too much fuckin' perspective".Cassini has been one of the greatest scientific triumphs I can remember. I often recall reading about Carolyn Porco back in 1980 when she was a mission specialist on Voyager, and here she is 36 years later heading up my favourite solar system mission of all (well, I guess Voyager rules them all, but Cassini has been the most engaging and involving). I remember saturating our dialup connection watching the live feed from Huygens' descent, now THAT has to be one of the most incredible pieces of engineering and execution we have ever achieved.I'm sad(ish) for the end but I CANNOT WAIT to see the science from the ring dive orbits.

Cassini-Huygens: Preventing Biological Contamination
The Huygens probe which landed on Titan was not sterilized as the chances of finding life were considered insignificant. From further investigations it is evident that chances for life on Titan are higher than initially thought. Although forward contamination in this case is still considered unlikely, it reinforces the need to ensure we protect extra-terrestrial chances of life.
