The cool white dwarf WDJ1330+6435 has accreted sodium-rich rocky material from its planetary system into its atmosphere. The immense atmospheric density causes the sodium to absorb light over a broad range of yellow, orange, and red wavelengths, giving the WDJ1330+6435 a ghostly green appearance (left). The cool white dwarf WDJ0902+2010 has a deep convection zone within its helium dominated outer envelope.

Other discoveries included planet-forming disks viewed edge-on, galaxies with huge clumps of stars and jellyfish galaxies . Adding a bit of mystery, there were even several dozen objects that defied classification altogether. This is a fantastic use of AI to maximize the scientific output of the Hubble archive, Gómez is quoted as saying in the ESA's announcement. Finding so many anomalous objects in Hubble data, where you might expect many to have already been found, is a great result. It also shows how useful this tool will be for other large datasets.
