Imaging from NASA 's Shuttle Radar Topography Mission STS-99 reveals part of the 180 kilometre (112 mi) diameter ring of the crater; clustered around the crater's trough are numerous sinkholes , suggesting a prehistoric oceanic basin in the depression left by the impact. [ 1 ]

Images of the aurora australis and aurora borealis from around the world, including those with rarer blue and red lights An aurora (plural: aurorae or auroras; from the Latin word aurora , "sunrise") is a natural light display in the sky particularly in the high latitude ( Arctic and Antarctic ) regions, caused by the collision of energetic charged particles with atoms in the high altitude atmosphere ( thermosphere ).

The Svalbard Global Seed Vault ( Norwegian : Svalbard globale frøhvelv ) is a secure seedbank located on the Norwegian island of Spitsbergen near the town of Longyearbyen in the remote Arctic Svalbard archipelago , about 1,300 kilometres (810 mi) from the North Pole . [ 4 ] It was started by conservationist Cary Fowler in association with the Consultative Group on International Agricultural Research (CGIAR), [ 5 ] and functions to preserve a wide variety of plant seeds in an underground cavern. The seeds are duplicate samples, or "spare" copies, of seeds held in gene banks worldwide. The seed vault is an attempt to provide insurance against the loss of seeds in genebanks, as well as a refuge for seeds in the case of large-scale regional or global crises .
Möbius strip
A Möbius strip made with a piece of paper and tape. If an ant were to crawl along the length of this strip, it would return to its starting point having traversed the entire length of the strip (on both sides of the original paper) without ever crossing an edge.

Cosmic Latte is a name assigned to the average color of the universe , given by a team of astronomers from Johns Hopkins University . [ edit ] Discovery of the color In 2001, Karl Glazebrook and Ivan Baldry determined that the color of the universe was a greenish white, but they soon corrected their analysis in a 2002 paper, [ 1 ] in which they reported that their survey of the color of all light in the universe added up to a slightly beigeish white .
