'Blood Moons' Explained: What Causes a Lunar Eclipse Tetrad?

The Night Sky Tuesday, April 15 After dark, look east for the lineup of Mars, Spica, and the just-past- full Moon, in that order from top down. Wednesday, April 16 The waning gibbous Moon rises soon after dark with Saturn hanging right close by. Watch them cross the sky together for the rest of the night. The Moon occults (covers) Saturn for southern South America; map and timetable. Thursday, April 17 Ganymede, the largest satellite of Jupiter, emerges from behind Jupiter's eastern limb around 10:18 p.m. Eastern Daylight Time. It disappears into eclipse by Jupiter's shadow around 12:06 a.m. EDT, then reappears around 3:29 a.m. EDT. Friday, April 18 Jupiter shines right under the big Arch of Spring this year. The Arch spans much of the western sky. Pollux and Castor form its top (as seen from mid-northern latitudes). To their lower left is one end of the Arch, Procyon, and farther to their lower right is the other end, Capella. Saturday, April 19 Have you said hello to Vega yet this year? The "Summer Star" is now sparkling low in the northeast at nightfall. By dawn it's high overhead. Sky & Telescope
