This week's sky highlights include the Big Dipper, which hangs in the northwest, with Mizar and Alcor visible near Vega. Titan casts its shadow on Saturn, an event that occurs every 15 years and is visible primarily from western North America. Watch the crescent Moon approach Mars and then Regulus, creating beautiful alignments. Cassiopeia is visible low on the northern horizon, while Alpha Centauri appears briefly for southern observers. Venus remains brilliant before dawn, with Saturn nearby. Mars and Regulus move closer for a conjunction in mid-June. The nearly full Moon will be near Antares by June 8. https://skyandtelescope.org/astronomy-news/observing-news/this-weeks-sky-at-a-glance-may-30-june-8/
