Unusually-looking Surface Features along the Plutonian Terminator
|
Da "NASA - Picture of the Day" del 16 Luglio 2015.
"An about 50 miles (such as approx. 80 Km) trip across Pluto would cover the distance indicated by the scale bar in this startling image.
The close-up of the icy world's rugged Equatorial Terrain was captured when the New Horizons Spacecraft was about 47.800 miles (approx. 77.000 Km) from the Surface, 1,5 hours (i.e.: 90 minutes) before its closest approach.
Rising to an estimated 11.000 feet (about 3500 meters), the Mountains visible here are likely composed of (mostly - added by Lunexit) Water Ice.
Suggesting surprising geological activity, they are also likely young with an estimated age of about 100 MY (Million Years). This speculation is based on the apparent absence of "fresh" Impact Craters.
The area pictured is near the base of Pluto's broad, bright and heart-shaped Region".

Ma, di certo, una visione simile, non credo che avremmo potuto averla....
Tu hai mai provato a guardare, con un OTTIMO binocolo e stando su un aereo a circa 10 Km di altezza, una città sorvolata dopo il tramonto (dunque quando non é più giorno, ma non é ancora notte)?
Io ho avuto questa fortuna.
I palazzi ed alcune strade si vedono (anche perché sono illuminati); ed anche alcune aree verdi (giardini e parchi). Ma i "dettagli" (che, in questo campo - il Nostro intendo -, sono fondamentali), proprio no. Impossibile.
Almeno per me.
