2. Hubble Astronomers Assemble Wide View of the Evolving Universe
NASA's InSight Prepares to Take Mars' Temperature
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 Friday, May 3
• Three zero-magnitude stars shine after dark in May: Arcturus high in the southeast, Vega much lower in the northeast, and Capella in the northwest. They appear so bright because each is at least 60 times as luminous as the Sun, and because they're all relatively nearby: 37, 25, and 42 light-years from us, respectively.
Saturday, May 4
• Vega is the brightest star in the northeast late these evenings. Look 14° (about a fist and a half at arm's length) to Vega's upper left for Eltanin, the nose of Draco the Dragon. Closer above and upper left of Eltanin are the three fainter stars of Draco's stick-figure head, also called the Lozenge. Draco always points his nose to Vega no matter in what part of the sky we see them. He seems awfully curious about it. Do dragons eat jewels?
The faintest star of Draco's head, opposite Eltanin, is 4th-magnitude Nu Draconis. It's a lovely, equal-brightness double star for binoculars and small scopes (separation 61 arcseconds).
• New Moon (exact at 6:46 p.m. EDT).
Sunday, May 5
• As night descends, look high in the west for Pollux and Castor lined up almost horizontally (depending on your latitude). These two stars, the heads of the Gemini twins, form the top of the enormous Arch of Spring. To their lower left is Procyon, the left end of the Arch. Farther to their lower right is the other end, formed by Menkalinan (Beta Aurigae) and then brilliant Capella. The whole thing sinks lower through the evening.
• Before the Moon returns to brighten the evening sky, learn to find (once and for all!) the famous galaxies M81 and M82 by using the faint "Mini-Dipper" attached to the Big Dipper's lip. See Matt Wedel's Binocular Highlight column and chart in the May Sky & Telescope, page 43.
Monday, May 6
• As twilight fades, look low in the west-northwest for the thin crescent Moon a few degrees above Aldebaran as shown here.
Sky & Telescope
Tuesday, May 7
•The crescent Moon hangs in the west-northwest at dusk near Mars and Beta Tauri (which is to Mars's left), and very close to or even on top of 3rd-magnitude Zeta Tauri.
Will the Moon occult Zeta for your location? It will if you're in Florida or the deep south (where the Moon will be low in darkness), the mid-south (with the Moon higher in twilight), or much of Mexico and Central America. See map and timetables from IOTA. (The text there consists of three timetables: for the star's disappearance, its reappearance, and the locations of the cities and towns. Watch for the divisions between the tables as you scroll.)
