The image shown here was taken on 22 August 2014 at a distance of 63.4 km from the comet centre. It shows the comet’s small lobe to the left, with the striking cliffs of Hathor clearly visible. In the foreground on the far right, the smooth Imhotep region can be seen on the large lobe. The image scale is 5.4 m/pixel and it measures 5.5 km across.

how did rosetta get this odd shape? the answer can be found with details at

So when two objects in space travelling at over 50, 000 km/hr, going in opposing directions smash into one another - they simply fuse together, Wow that's fascinating stuff. They must be right to , cause they got charts with arrows and numbers, this space science is very technical.

I guess you're assuming the word "opposing" would suggest 180 degrees, when it's actually any range of possibilities that would suggest enough of an angle to achieve asynchronous orbit with each other. Whether it's 1 degree or 180 degrees, it's just an assumption and that's the flaw in your comment and those desperate to prove how planets "evolved".

rosetta made a large loop around the comet to avoid damage and do some distance observation
a picture from close to the furthest point:

Comet on 30 September 2015 – NavCam



Copyright ESA/Rosetta/NavCam – CC BY-SA IGO 3.0

This single frame Rosetta navigation camera image of Comet 67P/Churyumov-Gerasimenko was taken on 30 September 2015 from a distance of 1488 km from the comet centre. The image has a resolution of 127 m/pixel and measures 130 km across. It has been contrast enhanced to better reveal the nature of the comet's activity.

and one day later it looked like:

Comet jet in 3D



Released 09/10/2015 12:00 pm
Copyright ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA

A 3D anaglyph view of Comet 67P/Churyumov–Gerasimenko based on two images from Rosetta’s OSIRIS camera on 12 August 2015, capturing a spectacular jet. The two images are separated by 2 minutes 28 seconds, which corresponds to a stereo angle of 1.2º. The image scale is 3.9 m per pixel. In this orientation the Babi and Aker regions are visible on the large lobe to the left, while Ma’at and the circular Hatmehit depression are seen on the small lobe to the right. Diffuse dust emission and other jets are visible all around the nucleus.
The image is best enjoyed with red–blue/green 3D anaglyph glasses.

Comet on 9 October 2015 – NavCam



Single frame enhanced NAVCAM image of Comet 67P/C-G taken on 9 October 2015.
Credits: ESA/Rosetta/NAVCAM – CC BY-SA IGO 3.0

This image of Comet 67P/Churyumov-Gerasimenko was taken by Rosetta’s NAVCAM on 9 October from a distance of 579 km.
The image scale is 49.4 m/pixel and the image measures 50.5 km across. The contrast is increased to better see the comet’s activity, with several distinct active regions clearly visible.
