mesmerizing Species

A graduate student found these mesmerizing structures attached to tree trunks in the Peruvian Amazon. He snapped a few images, shared with entomologists worldwide and hoped to find the name of the species responsible for such elaborate picket structure. So far no one has been able to verify what type of creature built it. Some believe it could be a relative of the ribbed-cocoon maker moth, which also builds a protective structure.

The rare image showing both day and night on earth

The image was taken by the crew on board the Columbia during its last mission, on a cloudless day. The photo is of Europe and Africa when the sun is setting. Half of the image is in night. The bright dots you see are the cities lights. The top part of Africa is the Sahara Desert. Note that the lights are already on in.Holland, Paris, and Barcelona, and that's it's still daylight in Dublin, London, Lisbon, and Madrid. The sun is still shining on the Strait of Gibraltar. The Mediterranean Sea is already in darkness. In the middle of the Atlantic Ocean you can see the Azores Islands; below them to the right are the Madeira Islands; a bit below are the Canary Islands; and further South, close to the farthest western point of Africa, are the Cape Verde islands. Note that the Sahara is huge and can be seen clearly both during Daytime and night time. To the left, on top, is Greenland, totally frozen.
