Cerenkov light detectors for gamma ray astronomy

Gamma ray astronomy. Cerenkov telescope at the High Energy Gamma Ray Astronomy (HEGRA) site at the Roque de los Muchachos Observatory on La Palma in the Canary Islands. Cerenkov radiation is the pulses of blue light given off by electrons creat- ed when a high-energy gamma ray from space strikes the atmosphere. These gamma rays have up to 10 thousand billion electron volts of energy. This instrument is one of the world's most sensitive Cerenkov detectors, using an array of small mirrors to focus the incoming light flashes onto a detector at upper left. HEGRA has many in- struments, of several types, spread out over hund- reds of square metres. Photographed in early 1997

Nile delta & Sinai peninsula as seen from Shuttle

Shuttle Columbia image (mission STS-52) centred on the Sinai peninsula. It has a triangular shape and extends from centre with its tip at bottom right, forming the Gulf of Suez (lower centre to bottom right) and the Gulf of Aqaba (bottom right) both in the Red Sea. Cyprus is visible, partly covered by clouds, at centre left in the Mediterranean Sea. The fertile valley and delta of the Nile are seen (dark) at bottom left silhouetted against the surrounding desert. The border between Egypt and Israel is found in the Sinai peninsula (centre frame) corresponding to the area marked by a sudden colour variation between the light desert and the darker brushland
