2. New U.S. weather satellite with improved camera sends back first images
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, January 24
• As dawn brightens on Wednesday morning the 25th, look very low in the southeast for the thin waning crescent Moon, as shown here. Saturn is about 14° to the upper right of it (for North America). Little Mercury is about 6° below the Moon. Binoculars will help, especially as dawn grows brighter.
Wednesday, January 25
• Sirius twinkles brightly after dinnertime below Orion in the southeast. Around 8 p.m., depending on your location, Sirius shines precisely below Betelgeuse in Orion's shoulder. How accurately can you time this event for your location, perhaps using a plumb bob or the vertical edge of a building? Of the two, Sirius leads early in the evening; Betelgeuse leads later.

• Right after dark this week, face east and look very high, almost overhead. The bright star there is Capella, the Goat Star. To the right of it, by a couple of finger-widths at arm's length, is a small, narrow triangle of 3rd and 4th magnitude stars known as "the Kids." Although they're not exactly eye-grabbing, they form a never-forgotten asterism with Capella.
Friday, January 27
• The sky's biggest asterism (informal star pattern) — at least the biggest that's widely recognized — is the Winter Hexagon. It now fills the sky toward the east and south after dinnertime. Start with brilliant Sirius at its bottom. Going clockwise from there, march through Procyon, Pollux and Castor, Menkalinan and Capella very high, Aldebaran over to Capella's lower right, down to Rigel in Orion's foot, and back to Sirius.
Betelgeuse shines inside the Hexagon, off center.
• New Moon (exact at 7:07 p.m. EST).
