Going to watch the fireworks? As you're waiting while dusk deepens, show someone the brightest sky sights. Big Jupiter is rising low in the southeast. The orange-red supergiant Antares sparkles higher in the south. Blue-white Vega is very high in the east, and yellowish Arcturus is very high in the southwest. And of course there's the ongoing Saturn-Mars-Regulus drama low in the western twilight.

Earth is at its furthest point from the Sun for the year. We are more than one million miles farther from the Sun than the average distance of about 93 million miles.
