2. NASA Releases Kepler Survey Catalog with Hundreds of New Planet Candidates
In this computer graphic, NASA's Voyager 1 probe, moving toward upper left, nears the edge of the sun's influence, flying through a region of space dominated by a "magnetic highway" that helps mediate the flow of particles into and out of the solar system. The region includes particles from the sun's southern hemisphere that have been forced northward by the pressure of the interstellar wind. Voyager 1 is expected to cross the boundary into interstellar space sometime within the next few years if not sooner. (Credit: NASA)

5. The Night Sky Sky & Telescope Tuesday, June 20
This is "Midsummer's Night," the shortest night of the year in the Northern Hemisphere. Astronomical summer begins at the solstice, 12:24 a.m. EDT (4:24 UT) on the 21st; that's 9:24 p.m. on the 20th PDT.
The term "Midsummer's Night" is left over from when the seasons were commonly defined as beginning and ending around the cross-quarter days. Be like your ancestors — build a bonfire tonight and organize some all-night revelry while magic is afoot. Dawn will come soon enough — when you'll see Venus over the crescent Moon, as shown above.

Do you know about the dark Propeller in the M13 star cluster in Hercules? With no Moon in the sky, take advantage of the dark to visit Sue French's six favorite summer deep-sky objects, which she features in the July Sky & Telescope, page 54.

Leo the Lion is a constellation of late winter and spring. But he's not gone yet. As twilight ends, look due west, rather low, for Regulus, his brightest and now lowest star: the forefoot of the Lion stick figure. The Sickle of Leo extends upper right from Regulus. The rest of the Lion's constellation figure extends for almost three fist-widths to the upper left, to end with his tail star, Denebola, the highest. He's walking down to the western horizon.

This is the time of year when, after dark, the dim Little Dipper floats straight upward from Polaris (the end of its handle) — like a helium balloon on a string escaped from some summer evening party. Through light pollution, however, all you may see of the Little Dipper are Polaris at its bottom and Kochab, the lip of the Little Dipper's bowl, at the top.
The waning crescent Moon leapfrogs past Venus between the mornings of the 20th and 21st for North America
