With the moon reaching its last quarter phase on Saturday, May 9, it begins to rise around midnight, then later each night. The effect is that the night sky as seen from mid-northern latitudes enters one of its final truly dark periods before summer\u2019s short nights take over. It\u2019s a gateway to spring\u2019s deep-sky season, when galaxies dominate the night sky, but also the perfect time to see some of the night sky\u2019s most famous constellations \u2014 even from light-polluted cities. Here are five things to see in the night sky this week. <\/p>\n The Leo Triplet is a small group of galaxies about 35 million light-years away in the constellation Leo. This galaxy group consists of the spiral galaxies M65, M66, and NGC 3628.<\/span><\/p>\n getty<\/small><\/div>\n<\/div>\n<\/figure>\n A last-quarter moon rises on Saturday, May 9. Half-lit as seen from Earth, it occurs week after May 1\u2019s full Flower Moon. As it rises around midnight, the evening skies are dark, revealing far more stars than in recent weeks.<\/p>\n<\/div>\n May is being dominated by two very bright points of light after dark. Look west 45 minutes after sunset to see Jupiter (highest) and Venus (lowest) in the western sky. They\u2019re getting closer to each other as they approach a close conjunction on June 9.<\/p>\n<\/div>\n This month is \u201cgalaxy season,\u201d with constellations like Leo and Virgo to the south, a window on the universe beyond the Milky Way. Any telescope will reveal a plethora of galaxies.<\/p>\n<\/div>\n<\/div>\n Look straight overhead, and you\u2019ll find the Big Dipper at its highest point of the year. For stargazers, it\u2019s an incredibly useful tool. The two stars at the end of its bowl point directly to Polaris, the North Star. Follow the curve of its handle, and you\u2019ll \u201carc to Arcturus,\u201d one of the brightest stars in the spring sky.<\/p>\n Follow that curve from the Big Dipper, and you\u2019ll land on Arcturus, glowing orange in the southeast. This is not just another bright star \u2014 it\u2019s a red giant about 37 light-years away, nearing the later stages of its life. Its warm color is easy to detect with the naked eye, especially from darker locations. Just beneath is the crescent-shaped constellation of seven stars called Corona Borealis, meaning northern crown. <\/p>\n A sky chart indicating how to locate the constellation Corona Borealis between the bright stars Arcturus and Vega.

High in the south, in the constellation Leo, lies one of the most rewarding galaxy groupings visible to amateur observers. The Leo Triplet (M65, M66 and NGC 3628) appears as three faint patches of light \u2014 each one a vast island of billions of stars. Under dark skies, binoculars can hint at them, while a small telescope reveals their elongated shapes.<\/p>\n Over the next week, conditions improve even further. The moon continues to wane toward the new moon on May 17, creating a dark-sky window that\u2019s one of the best opportunities of the entire spring for observing faint galaxies and star clusters. Later in the month, the cycle shifts. The Blue Moon \u2014 May\u2019s second full moon \u2014 on May 31 will brighten the sky for about a week before. June will bring summer constellations, such as the famous stars of the Summer Triangle, with August delivering a total solar eclipse on Aug. 12, followed by the peak of the Perseid meteor shower under dark skies.<\/p>\nKey Facts<\/h2>\n
