2. Chasing the Total Solar Eclipse from NASA’s WB-57F Jets
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)

Tuesday, August 1
The waxing gibbous Moon this evening forms a triangle with Antares to its lower left and brighter Saturn more directly to its left.
Wednesday, August 2
Now the Moon poses with Saturn. Although they look close together, Saturn tonight is is 3,500 times farther away: 81 light-minutes distant, compared to the Moon's 1.3 light-seconds.
Thursday, August 3
Saturn shines right of the Moon at dusk, and lower right of it as night grows late.
Friday, August 4
As soon as it's dark, look lower right of the bright Moon for the Teapot of Sagittarius. It's about the size of your fist at arm's length, tilting to pour to the right from its spout.
Saturday, August 5
The Moon shines low in the southeast as the stars come out. How early can you spot Altair, three fists at arm's length to the Moon's upper left? How about brighter Vega, nearing the zenith from the east?
