18 Delphini b

18 Delphini b, Arion

So luminous that it is faintly visible to the naked eye, 18 Delphini b is a gas giant exoplanet in the constellation Delphinus. This exoplanet has a mass of 10.3 Jupiters, and was detected in 2008 through radial velocity measurements. Also known as Doppler spectroscopy, this method is used to locate extrasolar planets and works by measuring the light spectrum and searching for periodic shifts towards the blue or red. Layers of color and a reimagining of the spectrum inspired this painting.
