And thanks to the supernova’s close location, astronomers may also be able to gather enough of its light to obtain rainbowlike spectra—wavelength-based breakdowns of its electromagnetic emissions.

Using the light from two transits of GJ 486 b to form a rainbowlike “spectrum”—a technique called transmission spectroscopy—revealed dark absorption lines that, much like a barcode, can be read to reveal water vapor’s presence there.

The key to that breakthrough was seeing the giant galaxy’s spectrum—a rainbowlike measurement of the various wavelengths, or colors, that an object emits or absorbs.

If the sun shines from directly above, the plane's shadow below will appear surrounded by rainbowlike bullseye.

From the overture — the harmonies for the brass instruments playing quietly, the sweeping, rainbowlike melody for the strings — it was evident that this would be a singularly vivid account.
