"On moonless evenings this month, see if you can spot the zodiacal light. This dim glow, aligned with the ecliptic, extends steeply above the western horizon well after the low arc of the twilight glow has diminished.

From completely dark locations, the zodiacal light is almost as bright as the Milky Way. The cone extends upward through Aquarius, Pisces, and Aries. A line connecting Mercury and Saturn shows the way. Scan your eyes left and right and your peripheral vision will pick up the cone-shaped glow. SOURCE: astronomy.com"

The Moon reaches perigee today 🌕
What’s that? The Moon’s orbit isn’t a perfect circle, so today it’s at its closest point to Earth—227,341 miles away (just over 1 light-second!). This happens at 4:00pm, marking the 2nd perigee this month.
