Any of various wading birds of the genera Egretta or Ardea that includes herons, many of which are white or buff, and several of which develop fine plumes during the breeding season
Energetic Gamma-Ray Experiment Telescope on the Compton Gamma-Ray Observatory (CGRO) This instrument has carried out an all-sky survey in many energy bands, along with dedicated pointed observations of particularly interesting or variable objects
Acronym for Energetic Gamma Ray Experiment Telescope on board the Compton Gamma Ray Observatory EGRET has detected photons as energetic as 9 GeV as late as 90 minutes after the onset of a GRB event
Energetic Gamma Ray Experiment Telescope An instrument on the Compton Gamma Ray Observatory (CGRO), launched 1991 EGRET made a complete survey of the sky from 30 MeV to 10 GeV EGRET showed the high-energy gamma-ray sky to be surprisingly dynamic and diverse, with sources ranging from the sun and moon to massive black holes at large redshifts Most of the gamma-ray sources detected by EGRET remain unidentified EGRET will be succeeded by GLAST
a long-legged, long-necked bird in the same family as herons and bitterns; their long sharp bill is good for spearing and capturing fish; common to rivers, shorelines and wetlands
a bird that lives near water and has long legs and long white tail feathers (aigrette). Any of several species (mainly in the genus Egretta) of wading birds in the same family (Ardeidae) as herons and bitterns. Egrets live in marshes, lakes, humid forests, and other wetland environments worldwide. They catch and eat small fishes, amphibians, reptiles, mammals, and crustaceans. They nest in trees and bushes or on the ground. Most are white and develop long plumes for the breeding season. The value of plumes as ornamental objects once drove egrets to near-extinction, but changes in fashion and strict conservation measures have allowed their numbers to increase. The great white egret is about 35 in. (90 cm) long; other common species average 20-24 in. (50-60 cm) long
