Space Image of the Week
The Night Sky
Friday, April 26· Around the end of twilight, the Moon rises below Saturn. With binoculars, look closer below Saturn for the wide double star Alpha2 and Alpha1 Librae, magnitudes 2.8 and 5.2 respectively. (They're numbered in order of their westward progression across the sky, not in order of brightness).
Saturday, April 27· Saturn is at opposition tonight: opposite the Sun as seen from Earth. See more under "This Week's Planet Roundup" below.· The waning gibbous Moon rises in the southeast very late this evening, with the red supergiant Antares sparkling to its right. By early dawn Sunday morning Antares is below the Moon in the southwest, as shown above.
The Night Sky
Sunday, April 28· The classic small-scope binary star Gamma Virginis, or Porrima, shines upper right of Spica, 14° from it (about a fist and a half at arm's length) these evenings. Porrima's two equal components were almost unresolvably close together for much of the last decade, but this spring they've widened to 2 arcseconds apart. Use high power. (An orbit diagram is in the May Sky & Telescope, page 51.)
Monday, April 29· It's almost May, yet the winter star Sirius still twinkles low above the west-southwest horizon in late twilight. How much later into the spring can you keep it in view?
