Good Red Friday evening, Rallypoint, and welcome to the February 4th Astronomy Picture of the Day (APOD): "Moons at Twilight." Moons, you say? Yes, Moons...our own is seen on the left as a slight crescent bathed in earthshine. In the upper right corner, however, is the planet Jupiter. That almost perpendicular line of stars arranged around Jupiter are in fact the Jovian moons Ganymede, [Jupiter], Io, Europa, and Callisto. Moons at Twilight. Now for some beach music...

Thank you my space-exploration advocate friend Maj William W. 'Bill' Price for posting the February 4th Astronomy Picture of the Day (APOD): "Moons at Twilight
Image: Moons at Twilight.
Explanation: Even though Jupiter was the only planet visible in the evening sky on February 2, it shared the twilight above the western horizon with the Solar System's brightest moons. In a single exposure made just after sunset, the Solar System's ruling gas giant is at the upper right in this telephoto field-of-view from Cancun, Mexico. The snapshot also captures our fair planet's own natural satellite in its young crescent phase. The Moon's disk looms large, its familiar face illuminated mostly by earthshine. But the four points of light lined-up with Jupiter are Jupiter's own large Galilean moons. Top to bottom are Ganymede, [Jupiter], Io, Europa, and Callisto. Ganymede, Io, and Callisto are physically larger than Earth's Moon while water world Europa is only slightly smaller.
