That's not lightning, and it did not strike between those mountains. The diagonal band is actually the central band of our Milky Way Galaxy, while the twin peaks are actually called the Spanish Peaks -- but located in Colorado, USA. Although each Spanish peak is composed of a slightly different type of rock, both are approximately 25 million years old. This serene yet spirited image composite was meticulously created by merging a series of images all taken from the same location on one night and early last month. In the first series of exposures, the background sky was built up, with great detail being revealed in the Milky Way dust lanes as well as the large colorful region surrounding the star Rho Ophiuchus just right of center. One sky image, though, was taken using a fogging filter so that brighter stars would appear more spread out and so more prominent. As a bonus, the planets Mars and Saturn are placed right above peaks and make an orange triangle with the bright star Antares. Later that night, after the moonrise, the Moon itself naturally illuminated the snow covered mountain tops.
The story of Dippy goes back more than 100 years. When fossilised bones were discovered by railroad workers in Wyoming in 1898, newspapers billed the find the 'most colossal animal ever'. After the specimen (later in the possession of Scottish-born millionaire Andrew Carnegie) was admired by King Edward VII, a 292-bone replica was produced and shipped to London.
When first unveiled on Fri 12 May, 1905, Dippy was housed in the Reptile Gallery, as it was too big for the Fossil Reptile Gallery. Since then, Dippy has undergone several moves and changes. Find out more about Dippy's history here: http://bit.ly/NHM_Diplodocus-This-Is-Your-Life
Early next year, the skeleton leaves Hintze Hall ready to embark on a new adventure, which will see it travel on a tour of the UK and allow more people than ever to see this iconic exhibit: http://bit.ly/NHM_DippyonTour
Chemical Formula: (Co,Fe)AsS
Locality: In Sweden, at Hakansbo, Vastmanland, as large twinned and untwinned crystals.

Glaucodot is a cobalt iron arsenic sulfide mineral with formula: (Co,Fe)AsS. The cobalt:iron(II) ratio is typically 3:1 with minor nickel substituting. It forms a series with arsenopyrite (FeAsS). It is an opaque grey to tin-white typically found as massive forms without external crystal form.

“She sells seashells on the seashore / The shells she sells are seashells, I'm sure” quipped Terry Sullivan quite tongue twistingly in remembrance of Mary Anning. And she did sell them and they were usually several tens of millions of years old, along with the ichthyosaurus she had found on the Jurassic Coast, the plesiosaur and what not. And her discoveries became a milestone in the evolution of modern palaeobiology and palaeontology and the way we see the Earth’s past. But read more on:
Depicted below is Geologist and palaeontologist Henry de la Beche’s (1796 – 1855) idea of life in ancient Dorset based on fossils found by Mary Anning (1830)
"To laugh often and much;
to win the respect of intelligent people and the affection of children;
to earn the appreciation of honest critics and
to endure the betrayal of false friends.
To appreciate beauty;
to find the best in others;
to leave the world a bit better whether by a healthy child, a garden patch, or a redeemed social condition;
to know that even one life has breathed easier because you have lived.
This is to have succeeded."
R. W. Emerson
