Hengefinder maps sun- and moon-framed city streets worldwide

Hengefinder is an app that predicts moments when the sun or moon lines up with city streets or buildings, creating a “henge” frame. Using astronomical calculations plus road data, it delivers instant results worldwide, showing sunrise, sunset, moonrise, and moonset for any place. Available on iPhone, Android, and the web, it stems from open-source code by Victoria Ritvo and highlights the real-world complexities of modeling roads, latitude/longitude, and the nuanced definition of “sunset.”

Hawaii's Emerald Sunset: Airglow and Gravity Waves Explain the Green Sky

A mysterious green glow seen over Hawaii at sunset is explained as airglow—faint light from oxygen in the upper atmosphere—amplified and structured by gravity waves, visible mainly through cameras with long exposure rather than to the naked eye; satellites and auroras were ruled out, and scientists call for more public observations to better understand this subtle phenomenon.

Jupiter and a Waxing Moon Put on a Sunset Sky Show

Look east at sunset on March 26 to see Jupiter near a waxing Moon; the Moon–Jupiter close approach occurs at 9:19 PM EDT (1319 GMT), with Jupiter about 5 degrees to the lower-right of the Moon. The pairing is best viewed from the northern hemisphere and remains visible through the evening, with Jupiter staying prominent in the spring sky until solar conjunction in July. A small telescope or binoculars will reveal the Moon’s craters and lunar seas and Jupiter’s cloud bands and moons; for exact rise/set times, check Time and Date for your location.
