5. The Night Sky
Friday, March 1 · Around 11 p.m. this evening (depending on where you live), the waning Moon rises with Saturn glowing a few degrees to its left, as shown above. The pair remain close for the rest of the night.
Saturday, March 2 · Now that March has begun, it's Sirius's turn to stand at its highest in the south soon after nightfall. 
Sunday, March 3 · Jupiter's moon Europa disappears into eclipse by Jupiter's shadow around 7:10 p.m. EST, after reappearing from behind Jupiter's eastern limb just 14 minutes earlier. Io disappears behind Jupiter's other side 10 minutes later. Europa then reappears out of eclipse at 9:38 p.m. EST, followed by Io at 10:50 p.m. EST.

Monday, March 4 · With Sirius on the meridian after dinnertime, so is the Winter Triangle — since Sirius is its bottom corner. The other two are Procyon to its upper left and Betelgeuse to its upper right. The Winter Triangle is almost perfectly equilateral: all three stars are 26° from each other within about 1° accuracy.
· Last-quarter Moon (exact at 4:53 p.m. EST).

The propeller-shaped white dashes near the bottom of this Cassini spacecraft image reveal the location of a small moonlet embedded in Saturn's A ring. The gravity of this tiny moonlet affects the orbits of nearby ring particles and creates the propeller feature, nicknamed Bleriot by imaging scientists, that Cassini sees.
