Any fan of Time Team will know that a lot of actually archaeology* is down to the final trowel work. The geo-pys and all the other work is pure guess work it's not until you actually unearth something that you know what it really is, indeed on Time Team how often over the three day excavation does what is being looked at change in the eyes of the experts.
Well we now have taken archaeology to whole new heights. Infra-red images taken from space have revealed more than 1,000 tombs and 3,000 ancient settlements. Early excavations have shown that some of these finds are precisely what the archaeologists believe them to be.
So as this is Towel Day it seems appropriate that NASA is getting archaeologists all excited about knowing where their trowel is.
* Like the famous British Telecom advert from the 80s I too got one Ology (related to this story), though I did pass rather a lot of others unlike Anthony.
