On the left is an image reconstruction of our ‘best guess’ at what comet 67P/Churyumov-Gerasimenko looked like in 2003. This was created using images from the Hubble Space Telescope in preparation for ESA’s Rosetta Spacecraft mission to travel there and take a closer look.
This closer look happened more than 10 years later, and just last week the Philae Lander was released and performed the very first soft landing ever on a comet. But even before this landing, we knew a lot more about comet 67P than we had in 2003. Images from Rosetta as it approached and began orbiting the comet showed us a completely unexpected shape, shown on the right, leading it to be nicknamed the ‘rubber duck’ comet.
The soft landing (or more strictly, bouncing) of Philae has been all over the news for the last week or so, but it was this article in Universe Today that drew my attention to the huge increase in knowledge about 67P over the last decade. We can easily get caught up in particular events and achievements but it isn’t often that we really sit back and appreciate how far we’ve come over a longer period of time. Continue reading
