Amazing picture. Still absolutely no idea what it is. Apparently the press are embargoed from reporting on something until the team release a paper, I'd imagine it's about that.
Hmm the flecks come across as a cryovalcano or geyser, or some sort of exposure of the sub-surface water and ice (perhaps the impact crater is relatively new going by the more pronounced edges?). Looks really shiny in the picture, but that's probably because of the long exposure contrast, Ceres is really really dark.
Here's another image of a different crater from June :
PS : The scale of the craters in rather fascinating. The Occator is thought to be 90kms wide and 4 kms deep.

Apparently it's actually two pictures mixed together, the main terrain is from a longer exposure but they've had to use much shorter ones to get any definition of the white spots as they're so comparatively bright (visible from Earth!)
Found this on /r/space. Utterly fascinating stuff.

Ok new photos of Pluto look stunning here

NASA have called a press conference for Monday concerning Mars, apparently.
So I often find myself in the garden late at night having a smoke and looking up at the milky way. I'm lucky I live in the country with little to no light pollution and can clearly see the full structure although not as spectacular as we see in those long exposure pics.
What I'm wondering is which part of the galaxy's spiral arms am I looking at, which direction, like am I looking inwards towards the centre, or outwards into intergalactic space, and is there any apps I can use on my phone to get long exposures and maybe get a semi decent pic?

Dunno about the camera app, but what you're looking at is the core (picture below to show our relative position):
Never been able to see it from where I am unfortunately
Shame we won't be around to see this :
This is fairly unreal, Pluto in HD - http://www.nasa.gov/sites/default/files/thumbnails/image/crop_p_color2_enhanced_release.png

God, I hope... if there's one thing I want to be able to do before dying, it's seeing earth from space and experiencing zero G/microgravity.
I was watching a video the other day entitled painting or photo, which was interesting to say the least. So I'll post a few in here. What do you think this is? No cheating.

Painting? The atmospheric glow doesn't seem convincing to me... and dead on as we'd see on a map, with the US dead centre? Would take some patience and maneuvering with the space telescope, or what have you. Not sure they'd bother.
Up near Greenland looks a bit suspect too. There looks to be a straight cloud front that crosses through a hurricane. Maybe stuff like that can happen in nature though, I dunno. Beautiful picture though.
paintingNo, that's a photo. How about this one?
earth looks real, but the moon doesn't. I say painting.Correctamundo.
How about this one?
That's (apparently) a still from the Nasa released gif/video of the moon passing earth.
It does look fake, not sure if it is or not. I'd say it was.
No I think that's real, seem to remember Obama tweeting it a couple of months back. Good ol' lunar farside which we never really look at.

Photo? With X-rays and gamma rays and whatnot coloured in within our colour spectrum so we can get a sense of them.
Apparantly this is a painting! Pretty amazing if true.
Tonight's super moon and eclipse - animation and timings for locations that can see it:

Already been burned by the Indo's reporting of Pluto and the findings are far from confirmed but there is apparently an unusual 20% darkening of a star named KIC 8462852 in the Cygnus Constellation.

Yeah that's been sensationalised somewhat 
Came here just to post just that. Apparantly we've just begun trying to listen for signals using the Allen Telescopic Array. http://www.space.com/30855-alien-life-search-kepler-megastructure.html
It's a longshot, but if we pick up anything remotely unusual - it's shit yer pants time.
Yeah, it had been mentioned for more than a week.
Scientists have been saying that the possibility of an alien structure there is incredibly low, though media have been making spectacular titles. Still, interesting to see if we can learn something more.

Yeah, someone mentioned above it's been sensationalised by the media. The article on Space.com points out there are already scientific explanations for the lighting and dimming.
...but I'm going to bite and get excited anyway
Just imagine for a second, if it really is a Dyson Sphere or an Alien structure. It's 1500 light years away, meaning what we're looking at occured 1500 years ago. This would mean that while we were on Earth doing this:
Somebody was already doing this:
...but yeah, it's probably going to be light fluctuation caused by a Pulsar or something.

It seems that the most likely scenario is that there is an another star there, whose gravitational pull brings many comets which make this light effect.
That's a very good point.
Just out of curiosity, are you a believer (like me) that given the scale of the universe and density of stars, that life must almost certainly exist?
Here is a fun little applet that talks you through a study by Kepler: http://exoplanets.newscientistapps.com/ - Every time I see it, my mind is blown!
