Nearly all the sky is covered by Lyman-α emission around high-redshift galaxies.

Galaxies are surrounded by large reservoirs of gas, mostly hydrogen, that are fed by inflows from the intergalactic medium and by outflows from galactic winds. Absorption-line measurements along the lines of sight to bright and rare background quasars indicate that this circumgalactic medium extends far beyond the starlight seen in galaxies, but very little is known about its spatial distribution.

An NGO approach for addressing the nutrition dilemma: Pohnpei focuses on awareness, food analysis, conservation, and food processing.

The establishment of the Island Food Community of Pohnpei, a non-governmental organization (NGO) based in Pohnpei, Federated States of Micronesia, presents a new approach for promoting Pacific Island food for its health and many other benefits. Its vision is holistic, stressing the importance of island food for sustainable development, economic benefits, self-reliance, improved health, cultural preservation, and human dignity, at the same time protecting the natural resources. A major reason for the establishment of this NGO is the emergence of an epidemic of nutrition-related health problems, including diabetes, heart disease, cancer, vitamin A deficiency, and anemia.
