2. Massive 400 Ft. Tsunamis on Ancient Mars
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)

Jupiter's moon Europa crosses Jupiter's face tonight from 9:24 p.m. to 12:12 a.m. EDT, followed by its especially tiny black shadow from 11:57 p.m. to 2:40 a.m. EDT. (Subtract 3 hours to get PDT.)

The enormous Arch of Spring is sinking ever lower in the west. As twilight fades, its top pair of stars, Pollux and Castor, still stand high in the west-northwest. Look for the Arch's left end, Procyon, about two fists at arm's length lower left of Pollux. Farther to the lower right of Castor is its right end: little Menkalinan and then brilliant Capella.
Jupiter's Great Red Spot transits Jupiter's central meridian tonight around 12:23 a.m. EDT.

With summer less than a month away (astronomically speaking), the last star of the Summer Triangle rises above the eastern horizon at the end of twilight. That's Altair, the lower-right corner of the Triangle. Its highest and brightest corner is Vega. The third is Deneb, sparkling less far to Vega's lower left.
