I’ve been rocking this bad boy for three years. It’s pretty well seasoned now. You’ll hear lots of Stanley Brothers, Vern Williams, Flatt & Skruggs and Bill Monroe. I tend to favor older recordings over modern ones. I recommend listening to it on your tiny smart phone speaker.
A possible super–earth–sized planet (between the mass of Earth and a gas giant) has been discovered 40 light years away that orbits its ~4.5 billion year old star in the habitable zone. This is a very good candidate for life if its size pans out.
The figure of each mirror (the technical term for the shape of the surface) is incredibly accurate: the bumps in the surface are on average smaller than 25 nanometers. A nanometer is a billionth of a meter… to give you an idea of how small this is, a typical human hair is 400 times thicker than the deformities in the mirror.
I’ll add that mirrors like this – the size they are, made of beryllium, figured to this accuracy – has never been accomplished before. And that’s only part of it, since of course all 18 mirrors must act as one once JWST is in orbit.
The James Webb Space Telescope will launch in 2018 if we are lucky. I can’t wait to see what we find!
Tisha is awesome. Of course all of us people with arms want to know how people without arms do everyday things. Does that make us petty? Maybe, but Tisha doesn’t care. She happily indulges our curiosities and answers all the questions we would otherwise be too shy to ask.
