What would happen to Earth if the sun was blue?

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. The sun wouldn’t still be around after 5 billion years.

What effect did the sun have on the evolution of the earth?

The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.

Is it possible for life to exist on the sun?

The Sun could not harbor life as we know it because of its extreme temperatures and radiation. Yet life on Earth is only possible because of the Sun’s light and energy.

Can you predict the outcome of life on Earth if our sun was blue?

Over a couple of weeks the earth would freeze. mean surface temp would drop far below -100C. All life forms would slowly die off.

Can you imagine life without light?

We would literally be lost in space. Without the Sun’s ray’s photosynthesis on earth would cease, plants would die and, all animals and humans who rely on plants for food would eventually die too and life on earth would cease to exist.

What would happen if the Sun became blue?

If the sun became blue with the same luminosity, the sky would just be bluer. The current blue sky is due to rayleigh scattering, which removes most of the light except blue. Blue sunlight would undergo the same scattering, but there is less light of other colors to begin with so less of the other colors to reach the surface.

How does the sun affect the sustainability of life on Earth?

The light from the sun is one of the major factors behind the sustainability of life on earth. Every other star produces light too, but only a small or no amount of it reaches the earth because of the huge distance.

Why does the Sun have different colors?

The Sun ( spectral type G2) radiates light in a particular distribution of colors, emitting more of some colors than others. Gases in Earth’s atmosphere subsequently filter that sunlight, absorbing some colors (wavelengths), and so more red light photons reach Earth’s surface than blue or green ones.

Will life on extrasolar planets have the same colors as on Earth?

As most stars do not have the same distribution of light in color wavelengths as our Sun, however, some researchers hypothesize that photosynthetic life on extrasolar planets will not necessarily have the same colors as on Earth. © Association of Universities for Research in Astronomy, Inc. (AURA).
