We can now see Rosetta’s goal, comet 67P/Churyumov-Gerasimenko thanks to researchers from the Max Planck Institute for Solar System Research and the European Southern Observatory. The comet disappeared behind the sun last October and it is just now out of the glare enough to be seen.
They took the image above with ESO’s Very Large Telescope. Actually the image is several exposures stacked together. Think of it is adding all the images together to bring out the features. 67P/Churyumov-Gerasimenko is small, around 3 x 5 km and it is about 740 million km / 460 million miles so it is very faint.
The new image suggests that 67P is beginning to emit gas and dust at a relatively large distance from the Sun – Colin Snodgrass from the MPS
The comet will become more visible to researchers as it gets closer.
