THE EAGLE NEBULA

Located 7000 light-years away, towards the constellation of Serpens (the Snake), this amazing stellar nursery is where ferocious young stars are born. The powerful light and strong winds from these new arrivals are shaping light-year long pillars, seen in images partly silhouetted against the bright background of the nebula.

The nebula itself has a shape vaguely reminiscent of an eagle, with the central pillars representing the talons of the bird. The 'Pillars of Creation' are in the middle of the nebula, with a cluster of young stars called NGC 6611 lying nearby.

Finger-like features protrude from the vast cloud wall of cold gas and dust, not unlike stalagmites rising from the floor of a cave.

Inside the pillars, the gas is dense enough to collapse under its own weight,The agro-ecological suitability of Atriplex nummularia and A. halimus for biomass production in Argentine saline drylands.
The choice of the best species to cultivate in semi-arid and arid climates is of fundamental importance, and is determined by many factors, including temperature and rainfall, soil type, water availability for irrigation and crop purposes. Soil or water salinity represents one of the major causes of crop stress. Species of the genus Atriplex are characterized by high biomass productivity, high tolerance to drought and salinity, and high efficiency in use of solar radiation and water. Based on a search of the international literature, the authors outline an agro-climatic zoning model to determine potential production areas in Argentina for Atriplex halimus and Atriplex numularia. Using the agroclimatic limits presented in this work, this
