Very faint planetary nebula Abell 7 is some 1,800 light-years distant, just south of Orion in planet Earth's skies in the constellation Lepus, The Hare. Surrounded by Milky Way stars and near the line-of-sight to distant background galaxies, its generally simple spherical shape, about 8 light-years in diameter, is outlined in this deep telescopic image. Within its confines are beautiful, more complex details enhanced by the use of narrowband filters. Emission from hydrogen and nitrogen is shown in reddish hues with oxygen emission mapped to a bluish-green color, giving Abell 7 a more natural appearance that would otherwise be much too faint to be appreciated by eye. A planetary nebula represents a very brief final phase in stellar evolution that our own Sun will experience 5 billion years hence, as the nebula's central, once sun-like star shrugs off its outer layers. Abell 7 itself is estimated to be 20,000 years old. Its central star is seen here as a fading white dwarf some 10 billion years old.
"We may be witnessing the confluence of two inherent components of the human condition: incompetence and self-interest. Nutrition has had many colossal and costly failures. The list of dietary components claimed to reduce cardiovascular disease (CVD), prevent cognitive decline, and/or fight cancer that were later refuted via clinical trials is extensive. And while the self-correcting nature of science necessitates failure, the vast majority of nutrition’s failures were engendered by a complete lack of familiarity with the scientific method" Edward Archer
