WHAT WAS THAT DARK SHADOW ON SATURN? A rare event just wrapped up on Saturn. Earlier today, the black shadow of Titan drifted across the ringed planet’s cloudtops. Many backyard astronomers in the Americas oberved the beautiful transit. Titan shadow transits occur only every 15 years during Saturn’s equinoxes. The next transit in the current series is Aug. 3rd. Mark your calendar!

MOTHS FOLLOW THE MILKY WAY: Astronomers come in all shapes and sizes–even invertebrates. A new study published in Nature reveals that Australian moths can see and decipher the night sky. They pay particular attention to the Milky Way and seem capable of navigating using the Carina nebula as a visual landmark.

POLAR VORTEX

THE POLAR VORTEX WOBBLED IN DECEMBER: Last month, sky watchers in Europe saw something rare and beautiful. A giant bank of polar stratospheric clouds (PSCs) escaped the Arctic Circle, and for more than a week they filled skies with rainbow color as far south as Italy. In the Italian comune of Sanfrè (latitude +45N), Pablo Javier Lucero was able to photograph the clouds at all hours of the day:

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
