Why is there a blue sun
When the Sun is high in the sky, the shorter waves, primarily the blue, strike air molecues in the upper atmosphere and bounce around and scatter.
Hence explaining why the sky looks blue.
Some people think that enough blue light is scattered out in the Earth’s atmosphere to cause the Sun to appear slightly yellow..
What is the biggest sun
The biggest: UY Scuti One day, the Sun will become a red giant. But if it had started its life with a dozen or so times its current mass, it could have eventually evolved into a red supergiant. (UY Scuti has already shed a lot of mass.)
Is Earth the only planet with life
Among the stunning variety of worlds in our solar system, only Earth is known to host life. But other moons and planets show signs of potential habitability.
What color is the sun
whiteThe color of the sun is white. The sun emits all colors of the rainbow more or less evenly and in physics, we call this combination “white”. That is why we can see so many different colors in the natural world under the illumination of sunlight.
Could a blue sun support life
As well, the sun has a moderate mass and temperature. This means it has the conditions for life to evolve. So, yes, a blue star could support life with very specific constraints on time and conditions – it’s just extremely unlikely, given what know about life.
What if our sun was a blue giant
Red stars have temperature around 2000- 3000K and blue stars around 10000–20000K. So imagine if sun would be a blue star, it would be so hot that it would become nearly impossible for a planet at a distance as earth to sustain life.
What would a blue sun do to a human
No. It would make regular humans dead. A blue star radiates most of it’s energy in the ultraviolet end of the spectrum. Light in those frequencies have a terrible tendency to give ordinary humans cancer and radiation poisoning.
What is the hottest star in the universe
The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.
Which color star is the coolest
Red starsRed stars are the coolest. Yellow stars are hotter than red stars. White stars are hotter than red and yellow. Blue stars are the hottest stars of all.
Why are Blue Suns hotter
Blue stars burn through their fuel at a tremendous rate. … So, remember, blue stars are blue because of the temperature of their surface. And they’re so hot because blue stars are much more massive than cooler stars like our Sun.
What would a blue sun look like
A blue sun wouldn’t change that. It would have a number of side affects though. Since blue stars burn hotter then red and yellow stars the Earth would be much hotter to the point that there would be no atmosphere and thus nothing to scatter any light. The sky would be black except for the very intense sun up there.
What would it be like to live under a blue sun
Originally Answered: What will happen to the humans if they were under a blue sun? They would die. The color of a star is directly related to its surface temperature. From coolest to hottest, it goes red, orange, yellow, white, blue.
What is the hottest planet
VenusVenus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night.
What if the sun was purple
Originally Answered: What would happen if the Sun turned into a different color like purple? Assuming the distance to the sun remained constant, this would be catastrophic for all life forms. The Earth would become an irradiated lifeless body like Mercury, and that’s if it didn’t receive enough heat to become molten.
What does the blue sun mean
A blue sun allows you to see — briefly — what the skies are like on Mars. All right, not literally into Mars, but blue suns do happen under circumstances which recreate conditions in the Martian atmosphere.
Is a blue sun hotter
Just for comparison, our Sun, which actually looks white from space, measures about 6,000 Kelvin. The hotter the star, the further up the spectrum you go. The hottest stars are the blue stars. … It’s surface temperature is a mere 11,000 Kelvin.
What if our sun was a black hole
Our Sun is too small a star to end its life as a black hole. But what would happen if the Sun were suddenly replaced with a black hole of the same mass? Contrary to popular belief, the Solar System would not be sucked in: a solar-mass black hole would exert no more gravitational pull than our Sun.
What is the biggest star in the universe
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.
What color would the sky be if there was no ocean
What color would the sky be if the Earth wasn’t mostly covered with water? I know the sky is blue because the light from the sun reflects off of the oceans, but what if there were no oceans? The sky is blue because of Rayleigh scattering, not because it’s reflecting the blue colour of oceans.
Which planet can support life
EarthAccording to the panspermia hypothesis, microscopic life—distributed by meteoroids, asteroids and other small Solar System bodies—may exist throughout the Universe. Nonetheless, Earth is the only place in the Universe known to harbor life.
Can a planet have a blue sun
Just as colors are made more dramatic in sunsets on Earth, Martian sunsets would appear bluish to human observers watching from the red planet. Fine dust makes the blue near the Sun’s part of the sky much more prominent, while normal daylight makes the Red Planet’s familiar rusty dust color more prominent.
