People are gazing at stars in the night sky for ages. Common notion that indicates clear visibility of stars in dark, limits most of our sky observation to night time. However, throughout history, luminaries from Aristotle, Aryabhatta to Sir John Herschel went off the track to inspect the day sky and brought out amazing observations out of it.
Literature on observational astronomy is filled with their reports on stars being visible during the daytime from the bottoms of mine-shaft, tall chimneys, coal pits, cisterns and many other sources beyond belief.
Folk tales also evidenced of the people chasing the celestial pinpricks of light reflected from the bottom of the deep lakes, rivers and well. The ability to figure out images of stars and other celestial bodies under such peculiar conditions compliments the mineshaft’s smaller visual angle or the greater contrasts offered by dark surroundings.
It was later found that the luminosity and color of the sky is same in a chimney or cistern as outside. This readily helped in adapting constant value of luminosity of sun light through any kind of exposure.
Unfortunately, most of the investigators relied upon the second-hand literature and ignored the experimentation. On the other hand, many failed to detect the exact results during the day observation usually due to time lag, low intensity of star light or poor visibility in the sunlight despite the use of high-quality binoculars and telescopes.
On that note, the Space investigators calculated the instants when a particular star or any other celestial body might appear in the sky during the daytime. All such attempts have eventually led to pinprick images of various planets, stars and other space bodies.
Some of the known results include, Moon, stars like Sirius, Sun, Arcturus, Fomalhaut, Betegeuse and Rigel, planets like Mercury, Mars, Venus, Jupiter, Saturn, some Earth-orbiting satellite, meteors, comets, black holes and much more!
In regard to bring it in effect, SDRO is organizing the upcoming Stellar Curiosity Workshop to present a practical approach of what you learned through text records. Sky gazing is equally an enjoyable activity during the day time.
SDRO is first of its kind to execute this innovative and exciting activity applicable for people of all age groups.
