John Frere, Account of flint weapons discovered at Hoxne in Suffolk, 1800. published in Archaeologia, England. Via Linda Hall Library

In 1797 Frere found a number of what looked to him like stone tools, “weapons of war, made by a people who had not the use of metals.” He was right, but no one would pay further attention to his discovery for the next 59 years. bladeandbone

Images of Jupiter’s moon Europa: Left is a Voyager mosaic, right is a new Gemini Planet Imager image. Caption:

 Comparison of Europa observed with Gemini Planet Imager in K1 band on the right and visible albedo visualization based on a composite map made from Galileo SSI and Voyager 1 and 2 data (from USGS) on the left. While GPI is not designed for ‘extended’ objects like this, its observations could help in following surface alterations on icy satellites of Jupiter or atmospheric phenomena (e.g. clouds, haze) on Saturn’s moon Titan. The GPI near-infrared color image is a combination of 3 wavelength channels.
