2. SwRI-Led Team Discovers Lull in Mars’ Giant Impact History
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, May 2
At nightfall, the first-quarter Moon forms part of a gigantic curving arc: To the Moon's lower left is Procyon, to its upper right are Pollux and Castor, and continuing way farther right, you can include Menkalinan and then brilliant Capella. These stars alone, minus the Moon, form the Arch of Spring.
Wednesday, May 3
The waxing gibbous Moon, 1.3 light-seconds away, shines near Regulus, 79 light-years away. Regulus is the bottom star of the Sickle of Leo, marking Leo's forefoot.
Thursday, May 4
The moon now shines under the belly of Leo — with Regulus to its right, Algieba a little farther to its upper right, and Denebola a lot farther to the Moon’s upper left.
Friday, May 5
Now the Moon is under Leo's tail star, Denebola (by about a fist at arm's length). To the Moon's lower left is bright Jupiter, with Spica about half again farther on.
