5. The Night Sky Thursday, June 2 · Saturn and Porrima have now closed to 17 arcminutes of each other, practically as close as they will get. Although they look like neighbors, Saturn is only 76 light-minutes from Earth, while Porrima is 39 light-years in the background. That's more than a quarter million times farther away! · Friday, June 3 · Look west in twilight for thin waxing crescent Moon far below Pollux and Castor, as shown here. · Monday, May 30 · Saturn's biggest and brightest satellite, Titan, is about four ring-lengths east of the planet tonight. Tuesday, May 31 · The brightest star in the east these nights is Vega. You can't miss it. Look for the little triangle-and-parallelogram pattern of the constellation Lyra dangling to its lower right. · The galaxies of the great Virgo Cluster are numerous but not that bright as Messier objects go. Nevertheless, if you have a dark sky, even binoculars are enough for you to hunt for ten of them as very faint smudges west of Epsilon Virginis. Use Gary Seronik's Binocular Highlight column and finder chart in the May Sky & Telescope, page 45. · Meanwhile, the dawn planet lineup continues to lengthen in the east, with Jupiter now very plain and easy. Wednesday, June 1 · Saturn (with Porrima next to it) and Spica draw the eye in the south after dusk. But don't forget Corvus, the Crow, below them. Corvus's uppermost bright star, Delta Corvi, is a wide telescopic double: magnitudes 3.0 and 9.2, separation 25 arcseconds. · New Moon (exact at 5:03 p.m. EDT). A partial eclipse of the Sun will be visible from much of the arctic. Parts of Japan, Alaska, and the Canadian Maritimes will also experience a very slight partial eclipse. Maps and details.
