One might think it is the backdrop for those Baptist Princeton Hospital Ads, but it's really just the blue sky, something of a rarity over the last week or so.
Here's another view.
Why is the sky blue? Here's the answer, at Science Made Simple with charts and figures and all. Basically, though, the answer is that the light from the sun is scattered after hitting gas molecules in the atmosphere (this is caused Rayleigh scattering). The scattering is more effective at short wavelengths or the blue end of the spectrum.
In space, the sky looks black because there is no scattering, since there is no atmosphere.
Enjoy the sky, and the clouds. Lay in the grass and look up at the clouds and name the shapes. Act like a kid.
Wooly Mulleins are science. This is a Wooly Mullein. Verbascum thapsus. Also called Great Mullein. There are several species and hybrids of mulleins. So maybe its not, but anyway, it's a weed, they say, but I have a difficult time killing one. I will mow around them, as I have this one for two years (they are biennials) or plant around them. There are a couple coming up next to my gate by the sidewalk in front. I guess I will just let them grow.
