If Hipstamatic hangs in and establishes itself as the go-to digital snapshot brand, it could double as a parable of commerce for the flat-world age: an industrial-era end-user experience without benefit of a workforce, a community or a pension plan.

What do the Gutenberg Bible, Tolstoy’s personal library, the Book of Kells—an 8th century illuminated manuscript, created by Celtic monks—and the Landsat Multispectral Scanner System (MSS) data archive have in common? They are all among the 245 international documentary collections that make up the Memory of the World Register. The register is a UNESCO (United Nations Educational, Scientific and Cultural Organization) effort to preserve access to documentary heritage around the world.

"We performed an image search on Yahoo for "Comet Holmes" on 2010 April 1. Thousands of images were returned. We astrometrically calibrated---and therefore vetted---the images using the Astrometry.net system. The calibrated image pointings form a set of data points to which we can fit a test-particle orbit in the Solar System, marginalizing out image dates and catching outliers. The approach is Bayesian and the model is, in essence, a model of how comet astrophotographers point their instruments. We find very strong probabilistic constraints on the orbit, although slightly off the JPL ephemeris, probably because of limitations of the astronomer model. Hyper-parameters of the model constrain the reliability of date meta-data and where in the image astrophotographers place the comet; we find that ~70 percent of the meta-data are correct and that the comet typically appears in the central ~1/e of the image footprint. This project demonstrates that discoveries are possible with data of extreme heterogeneity and unknown provenance; or that the Web is possibly an enormous repository of astronomical information; or that if an object has been given a name and photographed thousands of times by observers who post their images on the Web, we can (re-)discover it and infer its dynamical properties!

"This sudden brightening triggered a huge wave of interest from astrophotographers all over the world, many of whom posted their images on the web. To find out how many, Dustin Lang from Princeton University in New Jersey and David Hogg at the Max-Planck-Institut fur Astronomie in Heidelberg, Germany, searched the web. They found 2476 different shots of Holmes.

That's a significant astronomical database that represents a huge amount of work. But is it any use?

Today, Lang and Hogg use these images to work out an accurate orbit of Comet 17P/Holmes, a significant achievement given that the data is taken from an ordinary web search and its provenance is entirely unknown."

"How thin are the rings of Saturn? Brightness measurements from different angles have shown Saturn's rings to be about one kilometer thick, making them many times thinner, in relative proportion, than a razor blade. This thinness sometimes appears in dramatic fashion during an image taken nearly along the ring plane. The robot Cassini spacecraft now orbiting Saturn has now captured another shot that dramatically highlights the ring's thinness."

"I think these images are fascinating, because they support the experience I’ve made through biography writing, namely how little people actually change over time. They have an identity (from ‘identidem’: repeatedly, continually, constantly). In spite of many attempts in the humanities and social sciences over the last dacades to deconstruct the notion of individual identity, people usually remain the same over decades."
