Skywatch: Four of Jupiter's Galilean moons with binoculars visible on Sunday night | Metro & region



Sunday: Tonight Jupiter's four Galilean moons are visible on the eastern side of the planet. The moons are well separated so you can see all four with binoculars. As you watch the moons, they are in a different position every night. On Friday, only a few hours are visible on the east side for three moons. On Saturday, this number will be reduced to two moons for a few hours.

Monday: The last quarter moon appeared yesterday, but it will not be visible until this morning. When the moon is out today, it will be in the center of a bull, the bull horns.

Tuesday: A bright iridium flare appears in the eastern sky tonight. The torch occurs about eight degrees north of the bright star Altair 60 degrees above the eastern horizon. If the flair occurs at 8:52 pm, it will be the brightest object in the sky, twice as bright as Venus in the west.

Wednesday: The constellation of Scorpius is low tonight in south-southwest and contains several interesting star clusters. It is found by starting at the top of Scorpio's sting and moving 5 degrees to the top left to find the butterfly cluster. It is barely visible to the naked eye even from a dark place. Binoculars will resolve some stars in this cluster. With a small telescope and a little imagination, this cluster resembles the shape of a butterfly.

Thursday: The gap between Venus and Earth is shrinking as the two planets move closer together in their orbits. This will cause Venus to appear a little brighter, but it will seem more significant through binoculars. Every device aimed at the planet shows a broad crescent shape. In fact, Venus now appears about the size of Jupiter, and Venus will continue to grow in size over the next six weeks.

Friday: Neptune reaches the resistance today; Without the moon in the sky you can see it with a visual aid. Neptune is visible with binoculars or a telescope, but unlike most planets through a telescope, Neptune will only show a small slice. To discover Neptune, look for the constellation Aquarius in the southeast. Aquarius is not a bright constellation, but lies to the east of Capricornus. The planet is about halfway between the stars Gamma Aquarii and Phi Aquarii.

Saturday: Deep in the eastern sky this morning are the crescent moon and the star Regulus. The pair are separated by less than 2 degrees, but Regulus does not appear bright in the growing light of dawn. If your horizon is flat and clear enough, you can even spot Mercury about 3 degrees below the pair.
