Starship Asterisk*

@Owlice, thanks but I don't think that's the problem. The speed of light is an absolute value, that can not be surpassed by moving in opposite directions. I don't understand how this works, but it can be shown by experiment. @Rob and @Chris: I've heard from another source that objects that are very ...

Ok, I guess you guys have had this discussion a million times, but I don't understand that. Please excuse me if I'm boring you. I thought that the movement of a body is always defined as it's movement relative to another body . Otherwise how can it said to be moving at all? In an empty universe with...

Hi, thanks for the quick reply!

But ehm, so it really is true that objects can move faster than light? I thought this was impossible? How is this suddenly possible?

Hi, can someone explain this to me? I hope you don't think this is a stupid question. I've been checking out this APOD post And I made this comic about it. In other words, how is it possible that such ancient light only now reaches us? Shouldn't we have received this way earlier or are we really mov...

I've been looking at it more closely and I think it's just some kind of rock-formation or sand dune now. Although the illusion is quite impressive

Here's a larger view of the second tentacle-region:

Yes I can: here's the feature from a wider perspective:
And here's the picture's observation page which should contain all the information.

I found them on an unnamed ESA-picture in Google Earth (Mars-edition). The coördinates are marked in the lower right corner of the picture.

I don't think they are dust or sand-dunes. They always radiate outwards from hills. I found some more if you want to see them.

More questions: About 40km north of Mawrth Vallis, this smooth feature is lying on the Martian floor. The feature is about 40m in length, it's a bit curved and has a clearly visible shadow to the right. Anyone know what it might be? Is it really a thing lying at the floor or just an optical illusion...

Does anyone know what these strange tentacles emanating from these Martian hills are? I found them on an unnamed ESA-picture near Mawrth Vallis . http://4.bp.blogspot.com/_Z-NfUFZVWy4/TId8LRmxalI/AAAAAAAAAbA/IH_3SscUzGk/s1600/Whale_tentacles2.JPG http://4.bp.blogspot.com/_Z-NfUFZVWy4/TId8GHju4mI/AAA...

Yeah, I think I must agree with that view. Sure seems to be the case. Bummer, I thought I had found tracks of an alien rover on Mars. But it was fun though :) Thanks for all the help! Now that we're busy, I found this in the same area, just a little bit to the south. Looks great doesn't it? :) http:...

Ah ok, I see what you mean... Good that you mention it. I'll have too look more closely at the images to see if your theory might be correct.

Ofcourse you're welcome to investigate too! Hehe, this seems like a detective-game...

I hope I have time to find out more tonight.

To my eye the "trails" follow the hills and only coincidentally intersect craters, further suggesting volcanism as the trail maker. I don't know about that. All the trails seem to go from knob to knob or crater to crater. I've hardly seen trails that are not between two "knobs" ...

Here is a close up of the connecting features in visible light(?). If I'm not mistaken there's a dustdevil to the right. Can they be the cause of the features? Width of this image is about 2 km and it is from a spot about 400 km southeast of the Tyndall Crater. http://4.bp.blogspot.com/_Z-NfUFZVWy4/...

Does anyone know why these knobs and craters around Tyndall Crater on Mars seem to be connected? I found lots and lots of these connecting features around there, but I couldn't find anything about them on the web. Any suggestions? Width of the picture is about 170 km. It is taken from the Themis day...

Thanks for the reply, Mr. Neuendorfer. However, I don't think the catastrophic flows you are talking about are the same thing as my river. As you can see on the image, this river flows from dozens of sources, making it wider and wider while going downstream. So it is not a catastrophic event that fo...

Thanks
Yeah, I found a similar article just now (probably from the same source).

But I still think my river is way cooler and more riverlike

Great! I didn't know rivers existed on Mars. (That last one was indeed what I meant).

I don't know the exact scale of these photographs but it seems a pretty big river to me. Given that a pixel on the mosaic corresponds to 100m, I estimate it to be some 800 km long.

Hi, I was scanning the THEMIS 100 meter global daytime mosaic and I found this. http://2.bp.blogspot.com/_wWvzozlDj-M/TFcIu3HJZdI/AAAAAAAAACU/nwivr2ZYNcM/s320/RivierKlein.JPG It can be found in the mosaic at coordinates LAT -28.081 LNG 319.395 E. Can anyone tell me if this is some kind of Martian ri...
