2. Titan Experiences Dramatic Seasonal Changes
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, October 25
Draw a line from Altair, the brightest star high in the southwest after dark, to Vega, the brightest high in the west. Continue the line half as far onward and you hit the Lozenge: the pointy-nosed head of Draco, the Dragon.
The Great Square of Pegasus is now quite high in the east-southeast just after dark — still, for now, balancing on one corner (as seen from the world's mid-northern latitudes).
Wednesday, October 26
Low in the southwest in twilight, Saturn, bright Venus, and Antares form a nearly vertical curve, in that order from top to bottom. It's 7° tall.
Thursday, October 27
Now Saturn, bright Venus, and Antares straighten out into a nearly vertical line, as shown at right.
Friday, October 28
The low twilight lineup of Saturn, Venus, and Antares in the southwest now begins to bend the other way, as Venus moves east.
Around the same time, look for Arcturus low in the west-northwest.
