Because O-type and B-type stars with a giant luminosity classification are often somewhat more luminous than their normal main-sequence counterparts of the same temperatures and because many of these stars are relatively nearby to Earth on the galactic scale of the Milky Way Galaxy, many of the bright stars in the night sky are examples of blue ...
Taylor Hill/Contributor/Getty Images. It's true: blondes do have more fun in the summer.According to Black, this shade is going to be the most-requested at the salon as the weather warms up.
Diagram showing displacement of the Sun's image at sunrise and sunset Comparison of inferior and superior mirages due to differing air refractive indices, n. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height.

The Sun is a 4.6 billion year-old G-class (G2V) star and is more massive than 95% of all stars. Only 7.6% are G-class stars. The stars below are more similar to the Sun and having the following qualities: [1] Temperature within 50 K from that of the Sun (5728 to 5828 K) [a] (within 10 K of sun (5768–5788 K)).
At some point in the dawn of humanity, a smarter-than-average homo sapien moved a rock away from the fire for warmth and invented the thermal battery. These hot rocks can glow brighter than the sun.
Who's who?! It's no surprise that Hollywood's most stunning female stars have mothers who are even more stunning. These gorgeous mother-daughter pairs seriously have us seeing double.
The Sun's corona is much hotter (by a factor from 150 to 450) than the visible surface of the Sun: the corona's temperature is 1 to 3 million kelvin compared to the photosphere's average temperature – around 5 800 kelvin. The corona is far less dense than the photosphere, and produces about one-millionth as much visible light.
For example, directly scaling the exposure time from the Moon to the Sun works because they are approximately the same size in the sky. However, scaling the exposure from the Moon to Saturn would result in an overexposure if the image of Saturn takes up a smaller area on your sensor than the Moon did (at the same magnification, or more ...
