  Just spotted this too, really interesting!

  Very strange feature. Looks more of a formed shape than anything else I've seen so far.

  A Mars spot/pimple or alien temple? either which way very interesting

  Very strange object, looks too symmetrical to be natural, although the elevated ground looks natural.

  looks like an octagon shaped base with a rounded thimble type shape on top.

  Its the missing third tower of the Landmark Theatre Ilfracombe.

  Another possible plant showing initial root growth

  It looks like a lizard- or chameleon-like eyeball to me. Weird!

  It looks like a small razed cone with a jet of "stuff" coming out of the top #mini-volcano

  Is this a fan eruption in progress? That would be exciting!!!
  I thought I had found it first, but hey ho.....Whatever it is, it's cool.

• by Paul_Johnson

  No one has explained this artefact yet? What is it???

  Posted January 11, 2013 9:48 AM

• by Glynnmay

  The blurred top makes this look like a volcano that is in the midst of erupting? Very exciting

  Posted January 11, 2013 10:08 AM

• by Paul_Johnson

  Yes Glyn! It's the best picture of the lot! No one seems to care only you and me!

  I agree, mini-volcano erupting. This was spotted 2 days ago - look under Science 'space chimney'.

  Posted January 11, 2013 11:14 AM

• by Paul_Johnson

  What do the scientists say? It's by far the most fascinating image.

  Posted January 11, 2013 11:52 AM

• by Paul_Johnson

  I think there is a gas jet coming out of the side, as well as the dark stuff from the top....really interesting.

  What is this?

  Posted January 11, 2013 2:05 PM

• by chpets

  Saw this on the small thumbprint photo initially and the feature looked to be a crater, on the larger pic it looks volcanic.Lighting tricks

  Hey P4 Science dudes! Can you reveal which source image this comes from ? 😃 please...

  Yeah, c'mon Poindexter!

  That is pretty neat link michealaye! Paul, check it out as you can view it as zoomed in on.

  Posted January 11, 2013 10:51 PM

• by roybridge

  Saw this feature 3 days ago after Brian Cox on BBC's Stargazing Live asked viewers to log onto this site. Excellent link from michealaye.

  Posted January 12, 2013 12:27 AM

• by roybridge

  On michealaye's link the zoomed in image certainly does gives the impression that the strange feature is possibly the start of an eruption!

  Posted January 12, 2013 12:34 AM

• by Paul_Johnson

  Found the link and made it work! Thanks to all.
  Is this a cone of gas erupting, I think it is!

  Posted January 12, 2013 9:17 AM

• by Paul_Johnson

  It doesn't look like a boulder at all. It has fuzzy pixels above it which suggest gas. There are black fans in the vicinity....

  Posted January 12, 2013 9:18 AM

• by Paul_Johnson

  It is spewing black material out of the side of it and there is a white 'jet' coming from the same side (right).

  Posted January 12, 2013 9:19 AM

• by Paul_Johnson

  It is located direcly on a gas 'spider' and there seems to be a fresh deposit of white ice, which could suggest it is a new feature...

  #mystery object

  Posted January 12, 2013 9:44 AM

• by Paul_Johnson

  The link picture also has other unusual features....a weird cleft in the ice that is out of place in the top left of the image...

  Posted January 12, 2013 10:56 AM

• by Paul_Johnson

  and maybe a round hole in the ice next to the main anomaly, just to the right. Certainly the light is showing something different...

  Posted January 12, 2013 10:57 AM

• by JellyMonster

  You will see something different if you rotate the image 180 degrees. Ridges become channels, pits become boulders and vice versa.

  Posted January 12, 2013 4:39 PM

• by coolblack492

  OMG this looks amazing, i cant believe that this is the surface of mars. wow

  Posted January 12, 2013 5:24 PM

• by jdt79

  could be a caldera a collapsed volcanic cone with liquid co2 running off it carving out those snake like channels ?

  Posted January 12, 2013 8:00 PM

• by Paul_Johnson

  I think the wind would have eroded any volvanic cone, especially one this small. Vulcanism has been absent for many millions of years...

  Posted January 12, 2013 8:48 PM

• by michaelaye scientist

  the sun comes from the low-low right, therefore we believe this is a negative feature (crater-like). don't understand it yet,definit. weird

  Posted January 12, 2013 9:32 PM

• by Paul_Johnson

  Thanks Michael, I knew it was weird. I know it when I see it! It's a very exciting feature, hence me keep banging on about it. Sorry!

  Posted January 12, 2013 9:39 PM

• by Paul_Johnson

  Do you thing the dark blurring of the image at the top could be venting?

  Posted January 12, 2013 9:40 PM

• by Paul_Johnson

  The boulders in the original image, (thanks for the link!) all seem to have shadows on the right, but the sun is from the right?

  Posted January 12, 2013 9:49 PM

• by Paul_Johnson

  Interesting that the base has a hexagonal feature? I've seen pan ice on the sea adopt this pattern.

  Posted January 12, 2013 10:04 PM

• by michaelaye scientist

  yes, sun is from the low right, which makes this thing pretty certainly a cavity, a negative feature, not a dome.

  Posted January 13, 2013 8:55 AM

• by JellyMonster

  I am convinced all the photographs from this mission are upside down. Rotate through 180 degrees to see what these images should look like.

  Posted January 13, 2013 9:32 AM

• by Milkywaystars

  That spot is definitely a snail or an alien life form.

  Posted January 13, 2013 11:24 AM

• by Rockykrys

  I've rotated this image 180 degrees several times. Now convinced light IS from bottom right, shining into "crater" & north-south valleys.

  Posted January 13, 2013 12:16 PM

• by Rockykrys

  Might not be a crater, but certainly a hollow rather than a bump. Viewed up-side-down, the valleys are less convincing as "ridges".

  Posted January 13, 2013 12:22 PM

• by pocketmoon

  depends on the direction the sun light is coming from . Human brain assumed light is from upper left.

  Posted January 13, 2013 2:54 PM

• by Rockykrys

  The light appears to be from upper left when brain assumes that you are seeing ridges. Right-click and "view image" - it looks like valleys.

  Posted January 13, 2013 3:41 PM

• by Rockykrys

  i.e the bright bits are inside valleys, reflecting light that is actually received from bottom right. Hope this helps.

  Posted January 13, 2013 3:44 PM

• by Paul_Johnson

  It's taken me a long time for my brain to see this as a negative feature, but yes, it's probably a deep circukar shaft.....

  Posted January 13, 2013 6:48 PM

• by Paul_Johnson

  circular shaft....I should say, but has a hexagonal rim. Extraordinary! There's nothing like it on any other pic....

  Posted January 13, 2013 6:49 PM

• by Paul_Johnson

  Meteorite impact ? But why a hexagonal rim? That doesn't fit really.....an open vent-but still, there are thousands of fans, none with....

  Posted January 13, 2013 6:50 PM

• by Paul_Johnson

  ...this kind of opening through the ice into the Mars below. If it is a shaft, then probably gas made it, but why only one such feature...

  Posted January 13, 2013 6:52 PM

• by Paul_Johnson

  on all of the other pics.....and why hexagonals! This is still an amazing feature, and it has really captured my imagination...

  Posted January 13, 2013 6:54 PM

• by Paul_Johnson

  What a fantastic experiment this has been!

  Posted January 13, 2013 6:54 PM

• by Paul_Johnson

  Is it hexagonal all the way down? The darker material on the side suggest it could be.....

  Posted January 13, 2013 6:57 PM

• by Paul_Johnson

  The more I look the more I think impact crater from a small meteorite...though I cant explain the hexagonal feature. Anyone?

  Posted January 13, 2013 7:19 PM

• by Paul_Johnson

  If it is a meteor impact crater (a small one) then it must be very fresh, maybe? The ice around is shattered like a bullet hole in glass.

  Posted January 13, 2013 7:32 PM

• by Paul_Johnson

  I'm slightly embarrassed about the whole chiney thing now.....its a negative feature, but wow it looks like it's sticking up!

  Posted January 13, 2013 8:24 PM

• by Paul_Johnson

  I still think it represents something very unusual and important. It's a hole in the ice!

  Posted January 13, 2013 8:27 PM

• by DannyU

  I don't see it that way, and after a hard look I've decided it's probably a #dalek

  Posted January 13, 2013 8:43 PM

• by samuelchap

  yep definitely a dalek!

  Posted January 13, 2013 9:10 PM

• by Paul_Johnson

  It could be a soup dragon hole, I suppose, but no-there would be Clangers all over the place...

  Posted January 13, 2013 9:42 PM

• by Rockykrys

  I think the clangers' holes had lids? I'm still thinking a rock under the ice might play a part in the formation of this hole - see science

  Posted January 13, 2013 10:18 PM

• by BlueMoon58

  ESA Beagle 2 Perhaps?

  Posted January 14, 2013 12:50 PM

• by Paul_Johnson

  That would be cool! Crunch!

  Posted January 15, 2013 6:55 PM

• by itsanty

  looks a like a geyser just on the brink of erupting to me.

  Posted January 15, 2013 11:50 PM

  could this be an active vent? #sno-cone

  Do I see an 'ice ball' penetrating the surface?

  Posted October 31, 2013 3:12 AM

• by Kitharode moderator

  It's a hole. Nick-named 'Space Chimney'. More details here: http://blog.planetfour.org/2013/04/03/space-chimney-re-imaged/

  Posted October 31, 2013 2:54 PM

• by dfaxon

  Are there any other 'chimneys' around? If there are enough of the smooth craters around, maybe that's a good tag.

  Posted November 16, 2016 2:56 AM

• by Kitharode moderator

  Hi dfaxon. Far as I know, this is the only example of a 'space chimney' that's been caught on camera. Might be others, so keep looking. 😃
