2. Mars’ Oceans Formed Early, Possibly Aided by Massive Volcanic Eruptions
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, March 27
Look lower left of the Moon this evening for Regulus, the brightest star of Leo and the bottom of Leo's Sickle: a backward question mark about a fist at arm's length tall.
Wednesday, March 28
Now Regulus shines to the Moon's upper right after dark.
Thursday, March 29
Before the first hint of dawn tomorrow morning, meaning at least 90 minutes before your local sunrise time, spot Mars and Saturn glowing just 2° apart in the south-southeast. They're above the Sagittarius Teapot. Just below the two planets, almost forming an equilateral triangle with them, binoculars will show the big globular cluster M22, "the M13 of the south."
Friday, March 30
After nightfall, Orion is still well up in the southwest in his spring orientation: striding down to the right, with his belt horizontal. The belt points left toward bright Sirius and right toward orange Aldebaran and, farther on, the Pleiades.
