Astronomy Picture of the Day: Tiny Planet Timelapse .
“You can pack a lot of sky watching into 30 seconds on this tiny planet. Of course, the full spherical image timelapse video was recorded on planet Earth, from Grande Pines Observatory outside Pinehurst, North Carolina. It was shot in early September with a single camera and circular fisheye lens, digitally combining one 24-hour period with camera and lens pointed up with one taken with camera and lens pointed down. The resulting image data is processed and projected onto a flat frame centered on the nadir, the point directly below the camera. Watch as clouds pass, shadows creep, and the sky cycles from day to night when stars swirl around the horizon. Keep watching, though. In a second sequence the projected center is the south celestial pole, planet Earth’s axis of rotation below the tiny planet horizon. Holding the stars fixed, the horizon itself rotates as the tiny planet swings around the frame, hiding half the sky through day and night.”
NPR all tech considered: Super Sensitive Sensor Sees What You Can’t.
“A team of engineers at Dartmouth College has invented a semiconductor chip that could someday give the camera in your phone the kind of vision even a superhero would envy. […] Fossum calls his new technology QIS, for Quanta Image Sensor. Instead of pixels, QIS chips have what Fossum and his colleagues call “jots.” Each jot can detect a single particle of light, called a photon.”

What it says on the tin, the eclipse as seen from Wyoming, with a bonus appearance of the International Space Station. The ISS transit across the sun is fast, much faster than I thought it would be even though I’ve watched the ISS cross the sky many times.

On December 28, 2016 President Obama declared the Bears Ears National Monument in Utah. There’s no website for it yet on NPS.gov, but some info is available at Wikipedia.
Boston Globe Big Picture: Bear Ears Buttes in Utah.
“Known as Bear Ears for the pair of purple buttes at the region’s center, the newly proclaimed 1.9 million-acre National Mounument will preserve a photographer’s checklist of high-desert drama: spires, bridges, canyons. Yet the region’s true distinction is not its topography, but its cultural significance; perhaps no place in America is as rich with ancient Native American sites as Bear Ears. In October 2015, a coalition of five Indian nations, including the Hopi, Ute, and Navajo, formally proposed the monument, attempting to preserve the parcel’s 100,000 archeological sites from ongoing looting and grave robbing. Last June, in a letter to President Obama, more than 700 archeologists endorsed the proposal, saying that looting of the area’s many ancient kivas and dwellings was continuing “at an alarming pace” and calling Bear Ears “America’s most significant unprotected cultural landscape.””
(No typos added by me; the Boston Globe calls it Bear Ears instead of Bears Ears.)
The Guardian: Astronomy Photographer of the Year 2016 shortlist – in pictures.
“Gorgeous galaxies and stunning stars make up this selection of pictures from the shortlisted entries for this year’s Insight Astronomy Photographer of the Year award. The winners will be announced on 15 September, and an exhibition of the winning images will be will be displayed in a free exhibition at the Royal Observatory Greenwich’s Astronomy Centre from 17 September”.
