APOD: Opposite the Setting Sun (2018 May 03)

Post by APOD Robot » Thu May 03, 2018 4:08 am

Image Opposite the Setting Sun

Explanation: On April 30, a Full Moon rose opposite the setting Sun. Its yellowish moonglow silhouettes a low tree-lined ridge along Lewis Mountain in this northeastern Alabama skyscape. Sharing the telephoto field-of-view opposite the Sun are Earth's grey shadow, the pinkish Belt of Venus, and bright planet Jupiter. Nearing its own 2018 opposition on May 8, Jupiter is flanked by tiny pinpricks of light, three of its large Galilean moons. Europa lies just below Jupiter, and Ganymede and Callisto are just above. Closer and brighter, our own natural satellite appears to loom large but the Moon is physically a little smaller than Ganymede and Callisto, and slightly larger than water world Europa. Sharp eyes will also spot the trails of two jets across the clear evening sky.

Digital imaging is convenience but looking at the raw image with the awful digital artifacts makes me long for the gas-hypered Kodak Technical Pan days...

For me, looking at the resolution and fidelity of a digital image makes me mighty glad that we don't use film anymore, with its artifacts, grain, poor color, horrible dynamic range, and lousy resolution.

Love this shot as it shows just how wide an angle the jovian system spans in the sky. Too bad the glare from Jupiter makes it almost impossible to spot the moons with the naked eye.
I would love to see the RAW image of this, asit is I can make out one of the jets as a Southwest 737!

Thats not the raw image, it's just a higher resolution jpeg.

I see three pin pricks above and right of Jupiter, not just two. What is the third? An artifact? A random star. Io?

Because Venus is in the western sky, behind the camera. What we see here in the east is the Belt of Venus, the transition between light and dark created by the shadow of Earth's horizon being cast through the atmosphere.

<<The painting evokes Cupid's blind power as his mother, the cosmic divinity, blindfolds him. His brother is intent on observing the large number of arrows or fatal darts of love (a metaphor for amorous glances) the nymph is carrying. This entire painting is covered by a unified golden red shade that is particularly apparent in the colour of the sky. The colour scheme is completed by an economical use of blues and greens. Titian decided not to use the powerful, impasto highlights that are such a frequent feature of his works during the 1550s. The painting, in spite of the potentially joyous mythological subject and similarly to other works executed in this period, is pervaded with a degree of tension which is clearly evident in the sad and pensive expressions and in the intense colours of the fiery sky.>>
