A new book featuring stunning images of heavenly bodies has been published:The True Color of the Solar Corona
This is the first image of 10, published by the Telegraph newspaper (UK):
This extraordinary image displays the range of true coronal colors. The blue sky has been artificially removed close to the sun’s surface, revealing the green hues dominant in the innermost corona (1.8 million degrees Kelvin), caused by the presence of the element Fe XIV, known as coronium. The corona becomes progressively redder farther from the sun’s surface as dust particles scatter the shorter wavelengths of light
C 1396 is a large nebula in the constellation Cepheus spanning 3 full degrees of winter sky, the same angular distance of six full moons. This image highlights the conspicuous globule IC 1396A - a striking structure sculpted by the radiation of nearby stars
Me, too, Thomas. I haven't the slightest clue about the technology behind the photographs, but they're so beautiful! Just think: all of that ravishing beauty is out there!
