O’Bryan walked me slowly down the steep side of the mesa, to the desert floor, so I could see Star Axis in its entirety. The work’s centrepiece is a 10-storey staircase that lets you walk up through the rock of the mesa, your eyes fixed on a small circular opening that cuts through the top of the pyramid. The first section of the staircase is roofless and open to the sky, but the end of it has a stone overhang that makes it look and feel like a tunnel. This ‘star tunnel’, as Ross calls it, is precisely aligned with Earth’s axis. If you bored a tunnel straight through the Earth’s core, from the South Pole to North Pole, and climbed up it, you’d see the same circle of sky that you do when you walk through Ross’ tunnel. Gazing up through it in the afternoon glare, I saw a patch of blue, the size and shape of a dime held at arm’s length. But if the sun had blinked for a moment, fading the heavens to black, I’d have seen Polaris, glittering at the end of the tunnel, like a solitary diamond in the void.

Radio Free Earth
"Radio Free Earth finds the #1 song according to the Billboard Charts on a random (or determined) date, measures how long ago that date was, finds a named star that distance away, and then outputs which star that #1 song is just reaching at this moment." [more inside]

"Voyager's main transmitter shines at a feeble 22 watts, which is comparable to a car-mounted police radio or -- in visible light -- a refrigerator light bulb. Though incredibly weak by the standards of modern wireless communications, Voyager's signal is astoundingly bright when compared to most natural objects studied by radio telescopes." -- Even as Voyager 1 has left the Solar System (again), it can still be easily detected by telescopes on Earth

is a nifty online app that lets you input a geolocation and a date, and then uses google maps to graphically display the azimuth for the sunrise, sunset, and current time, for that particular date. Example: the sunset for the May 28 Manhattanhenge

An intriguing essay
on how young women in Georgian England were able to do science by hiding in the pursuits of the domestic arts.
"Women didn’t find it easy to participate in late eighteenth century science. Experimentation and discovery were not easily compatible with the ideals of domestic femininity – but there were women who rejected these social expectations and became active and renowned."

In the telling it has the contours of a creation myth: At a time of great evil and great terror, a small group of scientists, among the world’s greatest minds, secluded themselves in the desert. In secrecy and silence they toiled at their Promethean task. They sought the ultimate weapon, one of such great power as to end not just their war, but all war. They hoped their work would salvage the future. They feared it could end everything.
