APOD: Martian Chiaroscuro (2018 Apr 14)

Post by APOD Robot » Sat Apr 14, 2018 4:05 am

Image Martian Chiaroscuro

Explanation: Deep shadows create dramatic contrasts between light and dark in this high-resolution close-up of the martian surface. Recorded on January 24, 2014 by the HiRISE camera onboard the Mars Reconnaissance Orbiter, the scene spans about 1.5 kilometers. From 250 kilometers above the Red Planet the camera is looking down at a sand dune field in a southern highlands crater. Captured when the Sun was about 5 degrees above the local horizon, only the dune crests were caught in full sunlight. A long, cold winter is coming to the southern hemisphere and bright ridges of seasonal frost line the martian dunes.

So what's hiding under the black dot on the top left corner?

Looks like leftover Martian fingerprints. I'm hoping that older tech may lift some prints in 2020 with their own chiarosuro. :clap:

For Grumpy
The black point that you mention and enlarged to 500x, is seen as an image failure (missing pixel)

  • Perhaps because yesterday was Friday the 13th.

<<Phobos (Greek Φόβος) is the innermost and larger of the two natural satellites of Mars. Phobos is named after the Greek god Phobos, a son of Ares (Mars) and Aphrodite (Venus), and the personification of horror (cf. phobia).>>

Triskaidekaphobia (from Greek triskaideka = “thirteen” (tris = “three” + kai = “and” + deka = “ten”) + phobos = “fear”) is fear or avoidance of the number 13. It is also a reason for the fear of Friday the 13th, called paraskevidekatriaphobia (from Παρασκευή Paraskevi, Greek for Friday) or friggatriskaidekaphobia (after Frigg, the Norse goddess after whom Friday is named in English).
https://en.wiktionary.org/wiki/sesquipedalian#English wrote:
Sesquipedaliophobia : Fear of long words.

Latin sesquipedalis (literally “a foot and a half long”), from sesqui-, from Latin sesqui (“one and a half”); + pedal, from Latin pedis, form of pes (“foot”), + adjective suffix -alis; + adjective suffix -ian. Cognate to French sesquipédal. First used by the Latin poet Horace in his Ars Poetica, line 97 "sesquipedalia verba", "words a foot and a half long", referring to poets using excessively long words.

sesquipedalian (plural sesquipedalians)
  • A long word.
    A person who uses long words.
...................................................................
Hippopotomonstrosesquippedaliophobia (common misspelling, perhaps on purpose, to make the word even longer)

From hippopotomonstrosesquipedalian, an extension of sesquipedalian with monstrum (“monster”) and a truncated, misspelled form of hippopotamus (intended to exaggerate the length of the word itself and the idea of the size of the words being feared), +‎ -phobia.>>
