#Contrail #Shadow X
#Astronomy #Picture of the Day
Not really anything to do with astronomy. Have they run out of relevant material?
A little after #sunset and the #NewMoon at #dusk is approaching the #western #horizon, with #Earthshine illuminating the "dark" side. There's also #Venus there and, if you look very closely, you can also see #Saturn to the bottom right of the #planet. Add in a wisp of #cloud, an #aeroplane and its #contrail in the mid distance, #trees and a #house nearby and finish it off with a #sky turning from smoothly from deep #orange to a dark #blue and you end up with rather a nice collage. I used a #tripod to get a good #photograph here.
It has been a fine #winter #day today and the #Sun has been out for almost all of it. As it came to set, I took some #photographs of it but in the first one, I think the #Gull steals the scene.
In this second one, I think the #aeroplane and its short #contrail draw one's attention.

Looking #south-east, this #morning's #sunrise was filtered through #clouds which were illuminated #pink and #orange by the #Sun. The framing of this #photograph has a mix of natural and human-made features. There are some mysterious shapes silhouetted in the foreground and an #aeroplane leaves a #contrail in a clear portion of the #sky.
Two #photographs taken at #dusk. The first is just before #sunset with a #house and #trees in the #foreground in #silhouette. I like the #LensFlare in this #image.
The next was taken about a quarter of an hour later when the #Sun had passed over the #horizon. This illuminates to #clouds nicely. You can also see an #aeroplane and its short #contrail too.
Three non-conspiracies in one #photograph during today's #sunset. There is a #WaxingCrescent #NewMoon, to which humans have been in my lifetime. The #contrail that a passing #aeroplane is illuminated by the setting #Sun and is made up of water droplets condenses out of hot exhaust #gases of the #JetEngines. Oh, and the #Earth is round, as is evidenced by the fact that the Sun sets at different bearings on the #horizon at different times of year and the angle at which it sets is dependent on the latitude at which you happen to live.
loin des théories complotistes #chemtrail, le réel danger des #contrail, ces traînées blanches (de #condensation donc) que laissent les #avion à leur passage dans le ciel : un accélérateur de #changement-climatique
