Pluto has a 'moon'?

That's no Moon.

I want ice cream...

What flavour?

Doesn't matter, I'm putting it on my ass

Nice image of the earth and moon. Interesting to see just how dark the moon actually is - it's about the same colour and brightness as sunlit freshly-laid tarmac. Only appears as bright as it does as the sky is usually so dark by comparison!

Pluto flyby

Mega.

They both look fake to me.
Background would shirley have stars showing (unless they have been blacked out?) and the Moon/Earth size ratio looks all wrong to me.
I'm an expert now having watched a program about the Hubble Telescope the other night.

probes don't have 'normal' cameras on them, they have multiple different systems that take visual data from different wavelengths and whatnot, the data is then assembled back home to get your image, so yes they'll always look a bit artificial but they're fairly on the money as to what it would look like to be there. No you won't ever see stars as the aperture on the lens is turned down to stop the image being saturated.

Stars would not show. The camera will be set to expose the earth and moon correctly - and so would massively underexpose the stars.

Look at any photograph of the full moon taken from earth - you will won't see stars in the sky too.

The full moon (as viewed from earth) would have an apparent magnitude of -13. The brightest star (sirius) has an apparent magnitude of -1. That means the moon is around 60,000 times brighter than the brightest star.

A typical digital camera has a dynamic range of around 13EV. In other words it can expose difference in brightness of around 16,000 times - which is far too low to expose the moon and stars together.

As for the moon/earth size. It looks about right to me. The moon is around 27% the size of the earth - and looking at the animation, it looks like the disc of moon would fit just over three times across the face of the earth.

Pfft. I reported a 72MB one the other day - feck all happened.

That's not how it works. Their apparent relative size all depends on the field of view and distance from the moon. For example, there is a point somewhere nearer to the Moon (than the probe's position when it took those shots) that the Moon would have a similar apparent size to the Earth and occlude it from view altogether. There's no easy way to get an accurate single image that shows their relative size because the Earth will always be about a quarter of a million miles further from the camera. You'd have to position the camera perpendicular to the orbital radius at its mid point and have a wide enough field of view to cover the 225,000 to 248,000 miles between them into the picture.

why does it matter, who's on a dialup where it would be slow to load?
