SEE IN: IN each theme answer, the word SEE is found: CLOSE ENCOUNTERS, MISE-EN-SCENE, and PLEASE ELABORATE. The title of today's puzzle allowed me to make a confident guess about the theme. Always ...
AFTER DARK: The first word of each theme answer can be placed AFTER the word DARK to create a new phrase: DARK MATTER, DARK HORSE, and DARK CHOCOLATE. It's been a little while since we've seen ...
Sungazing is the unsafe practice of looking directly at the Sun.It is sometimes done as part of a spiritual or religious practice, most often near dawn or dusk. [1] The human eye is very sensitive, and exposure to direct sunlight can lead to solar retinopathy, pterygium, [2] cataracts, [3] and potentially blindness.
Stand with your back to the sun so you can see the shadow of your head and shoulders. Put the other piece of paper on the ground and hold the piece with the aluminum foil above it.
Sunspots are temporary spots on the Sun's surface that are darker than the surrounding area. They are one of the most recognizable Solar phenomena and despite the fact that they are mostly visible in the solar photosphere they usually affect the entire solar atmosphere.
The Milky Way is brighter in the Southern Hemisphere than in the North. (Photo taken at La Silla Observatory) [2]. The fact that the sky is not completely dark at night, even in the absence of moonlight and city lights, can be easily observed, since if the sky were absolutely dark, one would not be able to see the silhouette of an object against the sky.
The Sun's rotation was thus shown to vary by latitude and that its outer layer must be fluid. In 1871 Hermann Vogel, and shortly thereafter by Charles Young confirmed this spectroscopically. Nils Dúner's spectroscopic observation in the 1880s showed a 30% difference between the Sun's faster equatorial regions and its slower polar regions. [29]
With a conventional telescope, an extremely dark filter at the opening of the primary tube is used to reduce the light of the Sun to tolerable levels. Since the full available spectrum is observed, this is known as "white-light" viewing, and the opening filter is called a "white-light filter".
