Re: APOD: Teide Sky Trails (2010 Feb 12)

This is the first image of this type (the long exposure one) in which I've seen such clear differentiation of the colours of the stars ... does this require some kind of special camera or setup/post processing?

I don't use digg, but I think any excuse to expose the content of APOD to the masses is worthwhile. What sort of vote numbers are needed to get on the front page? Thousands?

Haha! I never thought I would actually see someone complaining about the use of international standard units !!

Re: Earth Images 'Live'

Hello - does anyone out there know of a source for up to the moment imagery of the planet? - I guess i'm hoping to find that there is an equivalent to 'google earth' but essentially in real time ie. 'Live' ?? Any suggestions?? Hi satoron. Unfortunately, there are no where near enough satellites up ...

Wow! I was actually joking when I brought up EU theory but... well what can I say.... But if we observe barionic matter via it's EM wavelength, doesn"t this mean that there is something to the EU theory? I even got excited when I first heard of the EU theory, then I went a checked some of the w...

Victoria Crater on Mars (APOD 22 Oct 2007)

http://antwrp.gsfc.nasa.gov/apod/astropix.html

The three parallel curving lines in the bottom left of the image struck me, any thoughts as to what they might be ?

Sorta reminds me of the lines left from successively lowering high tides :)

It looks like (at least, the 'holes' do) there is a region of local sink in those areas, so the dew point altitude (the height at which the cloud forms) is reduced in that location by the downward traveling cold air... I imagine this would happen more on calm days when thermal convection can get its...

In this case, the error is seriously compounded by describing the artist as a "scientific artist". Codswallop! There's sod all science in this picture.
It's almost as bad as the "science" they claimed to have in that abysmal movie Sunshine!

APOD 2007 June 19 - Eris

I understand that this is just an artist's impression... but the picture is flawed in just about every way it is possible for such a picture to be flawed. The sun seems very big at two pluto orbits distance, Dysnomia is practically grazing the surface of Eris it is so close, the shadow on Dysnomia i...

Two events this year that have got me all excited! The hexagon on Saturn and this! I have no doubt that the feature is real - these holes pop up in many photos so they are not errors in the photograph. What troubles me is that there appears to be no resolution of the interior at all, despite the fac...

So if the net magnetic field lines in the center are vertical, the travel path of the charged particles has a greater tendency to be vertical. If they're curved, the greater tendency is to follow the curved path. But can we really tell if their trajectories are less vertical near the edge of the sp...
