2. Hubble’s New Portrait of Jupiter
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
Friday, August 9
• The waxing gibbous Moon shines near Jupiter this evening, as shown here. But Jupiter, 40 times larger than the Moon, is currently 1,830 times farther away.
Jupiter's own four big moons, roughly as big as ours, are pinpoints in a small telescope or good, steadily braced binoculars. They're lined up east and west of the planet. This evening you'll find Europa to Jupiter's east and Io, Callisto, and Ganymede to its west, counting outward.
Saturday, August 10
• Narrow windows for good Perseid viewing. The annual Perseid meteor shower is predicted peak late on the night of August 12-13, but the waxing gibbous Moon won't set that night until just before the beginning of dawn.
You may do better a day before that, on the morning of the 12th, if you catch the hour or so of dark sky between moonset and the start of dawn (for North America). And, there's a possibility this year of a second peak in the meteor rates due right around then for North America (around 10h UT August 12th).
A day earlier on the morning of the 11th — late tonight, in other words — we get twodark hours before dawn, but the meteor rates will probably be low. However, there are indications that this year's Perseid shower is bringing some unusual early fireballs.
Not sure when dawn begins? At this time of year it's about 1 hour 45 minutes before your local sunrise time if you're in the world's midnorthern latitudes (near 40° N.)
Here's the International Meteor Organization's near-real-time graph of Perseid activitythis year, based on scientific, standardized-method meteor counts coming in from visual observers around the globe.
Sunday, August 11
• The Moon shines with Saturn tonight, 3° or 4° to Saturn's right as seen during evening in North America.
Physically Saturn is 35 times as large as the Moon (not counting the rings), and tonight it's 3,500 times farther away.
Saturn's own largest satellite, Titan, is 1.5 times as large as our Moon. A small or medium-size telescope shows it tonight as an 8.5-magnitude orange pinpoint, about four ring-lengths to Saturn's west.
Monday, August 12
• It's supposed to be peak Perseid night, but you'll have the bright light of the waxing gibbous Moon washing the sky, so only the brightest meteors will show through. Best time: the later in the night the better, right up to the beginning of Tuesday's dawn.
Not sure when dawn begins? It's about 1 hour 45 minutes before your local sunrise time if you're in the world's mid-northern latitudes (near 40° N.)
Tuesday, August 13
• The nights around full Moon, such as now, are traditionally considered the worst for lunar observing. But not if your interest is crater rays! These show best under high, shadowless illumination.
