The highest Greenland temperatures in 1000 years

Recent high temperatures on the ice sheet in central and northern Greenland lies are unique, when compared to 1000 years of reconstructed climate conditions on the ice sheet.

New method to map the surface of the moon increases accuracy to unprecedented levels

This new method uses a much more direct and precise calculation, it doesn’t rely on a whole set of parameters to be fed into the computer, and it can even calculate the uncertainties and the accuracy.
