Starship Asterisk*

Truly an iconic photo.
Probably has been for many, but it's now my screen background. The download from APOD comes up on the desktop without the moon and with the Earth in the right half of the screen - perfect unless you like lots of icons (sic!).

All, The history of criticism and cynicism about shadows in space exploration pics is shameful - eg Apollo - and I enjoy this simulated pic of a Mars Rover on its ground, but ...... The shadow of the Rover is shown as diffuse. Shadows in real pics are sharp. Is this supposed to be during a dust stor...

All, The other similar star, V838 Mon has appeared again on APOD - 26th November 2005. In 2003, the Hubble site published a 'video' of this star, http://hubblesite.org/newscenter/newsdesk/archive/releases/2003/10/video/a, in fact a short series of stills that dissolved, one into the next. Has anyone...

Craterchains, The original image on APOD is only 156K - how can your superduper monitor show any more detail on that than an ordinary one? So please show us where the craters are, using one line as an example. I enclose a reduced image with arrows that show one 'streak', taken at random, that I can ...

craterchains, Here's the list of Google hits: 1/ http://www.craterchains.com/ (Your's?) Quote from FIRST paragraph:" After exhausting all other ideas and the given theories surrounding crater chain formations we settle on weapons as the most likely cause." 2/ http://www.sciforums.com/showt...

Thank you, craterchains, I had almost forgotten this thread! However, I'm worried by your attribution of these markings to "CS crater chains" as Googling for that gets loony "extraterrestrial strafing runs" sites and abusive message boards. I am reassured that "crater chains...

All, This object's appearance most reminded me of a barnacle covered rock, from which part of the colony has been ripped. Please note, I am NOT suggesting that Hyperion is animate, just suggesting an anologue. In good conditions, and over a long (biological!) period of time, colonies of barnacles wi...

All, Serge Brunier has kindly replied to my query, as follows; __________________________________________ :-((((((((((( Dear John, I'm frustrated by your mail : I think to this picture nearly one year before to go to Chile to take it... My intention was to SHOW OUR MILKY WAY AS IT WAS SEEN FROM OUTS...

Sorry to be pedantic, but no one has answered my question. Which is, what is the galaxy shown in that APOD? It looks to be taken from outside the galaxy shown, so it can't be the Milky Way, as we're in it! It could easily be a view of a distant galaxy seen edge on. Or, as I think Empeda implies, thi...

Today's APOD purports to be the Milky Way, but is it? Or another galaxy (far, far away?) that happens to be of the same sort and seen edge on from here?

Makc, Thank you for that advice! This is a gif composite of four images, two of Rhea and two of Dione; in each pair one is from Cassini and one from Voyager. The features in question are marked by arrows. http://img99.echo.cx/img99/9489/linesonrheaanddione9lg.gif The composite has been compressed to...

Makc,
A composite is ready, but how can I upload it?
John

My previous post in this thread has been studiously ignored. If I were a conspiracy theorist....... Now the lastest APOD is of Rhea again, but from an angle that doesn't include any features that I can pick out from the previous view. So nothing new about the Line. But it is there! See previous post...

All, The APOD for the 15th February showed a new view of Rhea from Cassini, and commented on the wispy white lines on that moon and on Dione. It did not comment on the extraordinary straight line feature that cuts across the globe from 8 o'clock to 5 o'clock in this view. This line is real, not an a...
