Watchful Eye on the Sun
Researchers at the »Big Bear Solar Observatory« (bbso) in California are looking to obtain new insights on the activities of our most important heavenly body.
The sun means light, warmth and life. It dictates our rhythm each day and night, during summer and winter. For as long as mankind can remember, scholars have been following the path of the fireball in the firmament. Using more and more sophisticated instruments, researchers all over the world are trying to unravel the sun’s remaining secrets, both with satellites and using telescopes here on earth. Big Bear Solar Observatory (BBSO) not only owns the newest solar observation device, with a 1.7 meter Zerodur® mirror substrate from SCHOTT, this is also the world’s largest. The observatory is located on a man-made tongue of land in California that stretches into a lake 2,000 meters high in the San Bernardino Mountains, east of Los Angeles.
The ideal location for the high-tech observatory:
