Blue Planet.jpg the color is said to be a result of the light passing through the crystals that surround this planet 63 light years from Earth

Y'all know that's an artist conception, right? No telescope in Earth can image an exoplanet.


Besides which, I have a far more accurate picture of the blue planet.

Poor thing!

The Hubble Space Scope found it then scientists calculated the color it must be from data they received. Ready for this? It rains sideways on this planet which is a ball of gas!!!

[1] In 2007 NASA's Spitzer Space Telescope measured the infrared light from the planet, producing one of the first ever temperature maps for an exoplanet. The map shows that day- and night-side temperatures differ by about 260 degrees Celsius, causing fierce winds to roar across the planet. The condensation temperature of the silicates (over 1300 degrees Celsius) mean these particles could form very small grains of glass in the atmosphere.

[2] Albedo is a measure of how much incident radiation is reflected. The greater the albedo, the greater the amount of light reflected. This value ranges from 0 to 1, with 1 being perfect reflectivity and 0 being a completely black surface. The Earth has an albedo of around 0.4.

[3] This technique is possible because the planet's orbit is tilted edge-on as viewed from Earth, so that it routinely passes in front of and behind the star. When the planet passes behind its host star, the light received from the system drops by about one part in 10 000.

[4] The deep blue colour of HD 189733b is consistent with the "red sunset of HD 189733b" result from the transit spectrum (heic0720). If sodium absorbs red light and dust scatters red light, the atmosphere will redden light shining through it, but will appear blue in reflected light.

[5] The colours of Jupiter and Venus are both due to unknown particles within the atmospheres of the planets. Earth looks blue from space because the oceans absorb red and green wavelengths more strongly than blue ones, and reflect the blueish hue of our sky. The shorter blue wavelengths of sunlight are selectively scattered by oxygen and nitrogen molecules in our atmosphere via a process called Rayleigh scattering

I posted earlier it rains sideways there, now I know why. I just read the daytime temp is 2,000 degrees F and the winds are 4,500 mph. Sailing anyone?

Wait, according to whom? This looks like artwork.
It is. They used the spectroscopic analysis for the color - this is what it reflects in the visible light bands.

Some of you posters must be stuck in the 1950's technology wise.
