New Horizons - one of the most exciting space probes of this decade in my opinion has surpassed the orbit of Neptune. Still almost a year to go until the flyby, but within a short while, it will be beaming back the best photos we've ever had of pluto.

Now only 46days to closest approach of Pluto. This is quite a landmark in Astronomy - I think it's the first new world to be revealed for several decades and the last of the classic 9 planets to be revealed, a century after it's existence was predicted.

Latest pictures (taken mid-may, released a week or so ago), show a fair bit of surface detail now - so it looks like we're going to get some exciting photos over the next couple of months.

This is more like it:





Still ~5million miles away, with the flyby occuring in 4days time, at which point, the resolution will be 500 times better than this image.

I really can't get my head around how fast this tiny spacecraft is travelling. 27,000 mph now and it was doing 51,000 mph when it went past Jupiter.

But, of course, the Earth is moving at an even faster speed around the Sun - 67,000 mph. Better nail everything down.

& that's just the speed within the Solar System (i.e. rotation around the sun). The Solar System is whizzing around in our galaxy even faster, & that's moving relative to...

It's all relative, as they say!

Oh exactly - I was just referring to a frame that is relevant for New Horizons.

I think the Sun is moving at 450,000 mph around the Milky Way and that is moving at 1.3 million mph relative to the cosmic microwave background, or 2.2 million mph relative to other galaxies. (There are varying figures depending on where you look.)

It's getting more and more difficult not to fall off the sofa.
