Happy Monday, Beagle fans! Today's Airy Monday post includes news from space -- Hayley's comet, GRACE satellite shows water cycles, building blocks of life in a distant galaxy -- plus an academic Pagan conference calls for papers and a scholarly collection of sources on witchhunting history.

First up: news from SPACE! (How much more Airy can you get?) October's skies will light up with some extra excitement 10 days before Samhain, courtesy of Hayley's Comet. Get the details here.

This time-lapse slideshow using data from Nasa's GRACE satellite shows the seasonal water cycle in the U.S. for the past decade.

More evidence that we may not be alone in the universe: In a paper published in the journal Science on September 26, astronomers reported discovering a complex molecule needed for life in the gaseous star-forming region Sagittarius B2. The finding suggests that the building blocks of life may have their origins in interstellar space.

In news of Pagan interest in academia:

The publication of the Penguin Book of Witches makes a large number of source materials on the Great European Witch Hunt available to the general public. NPR's review suggests that there's a wider implication about oppression of the disadvantaged in the book.

The Conference on Current Pagan Studies has extended its call for papers on its upcoming topic: "Fecundity and the Richness of the Dark."
