Lindholm Høje

"Lindholm Høje (Lindholm Hills, from the word for hill or mound) is a major Viking burial site and former settlement situated to the north of and overlooking the city of Aalborg in Denmark. The southern (lower) part of Lindholm Høje dates to 1000 – 1050 AD, the Viking Age, while the northern (higher) part is significantly earlier, dating back to the 5th century AD.[1] An unknown number of rocks were removed from the site over the centuries, many, for example, being broken up in the 19th century for use in building roads..."

Anundshög

Anundshög is a tumulus in Sweden. It has a diameter of 60 metres (200 ft) and is about 9 metres (30 ft) high, dated between the Bronze Age and the late Iron Age. A fireplace under it has been dated by radiocarbon dating to sometime between AD 210 and 540. Some historians have associated the mound with the legendary King Anund. http://en.wikipedia.org/wiki/Anundsh%C3%B6g

At the foot of the mound are 2 large stone ships placed end to end, 51 metres (167 ft) and 54 metres (177 ft) long. Two other stone ships are visible. The site was a thing-place and the ship settings may be associated with this function, according to Wikipedia.

Astrophile: Saturn's egg moon Methone is made of fluff - space - 17 May 2013 - New Scientist

"Out among Saturn's menagerie of moons, a shiny white egg rests in a nest of ice crystals.
Named Methone, this small, oval moon was seen in close-up for the first time last year by NASA's Cassini spacecraft. Methone is utterly unlike the other small balls of ice and rock that dot the solar system, which are deeply scarred by impacts. Instead it is smooth, with not a hill or pockmark in sight. Now astronomers may have a clue as to why: Methone is made of lightweight fluff."Astrophile: Saturn's egg moon Methone is made of fluff - space - 17 May 2013 - New Scientist

Assembly line

"The assembly line was invented 100 years ago. It’s time to invent the disassembly line", Steven Cherry is telling at http://spectrum.ieee.org/podcast/at-work/innovation/the-future-of-the-assembly-line

Deep Space Beacon

Pulsed gamma rays from the Vela pulsar from photons detected by Fermi's Large Area Telescope. The Vela pulsar is the brightest persistent source of gamma rays in the sky. The bluer colour in the latter part of the pulse indicates the presence of gamma rays with energies exceeding a billion electron volts (1 GeV). For comparison, visible light has energies between two and three electron volts. Red indicates gamma rays with energies less than 300 million electron volts (MeV); green, gamma rays between 300 MeV and 1 GeV; and blue shows gamma rays greater than 1 GeV. The image frame is 30 degrees across. The background, which shows diffuse gamma-ray emission from the Milky Way, is about 15 times brighter here than it actually is.

Caesar and Arles

Image processing of the Arles bust 

It was probably between 49 and 46 BC, when Caesar had close relationships with Arles that, according to the French archaeologist Luc Long, who found it in 2007 after struggling with poor visibility, strong currents and the catfishes of Rhone, the famous marble bust of Arles had been carved. This beautiful portrait, discovered in the depths of the right bank of the river near Arles, has been undoubtedly attributed by Long to Julius Caesar. Here we compare the Arles bust with some others and propose the application of image processing and multimodal biometric systems to the ancient artifact. ... More at SSRN
