Do Fullerenes solve the 100 year old Diffuse Interstellar Band mystery?

Event Information:
In 1919 Mary Lea Heger demonstrated that certain diffuse absorptions in reddened spectra were of interstellar origin. Many hundreds are now known. In 1988 Harry Kroto suggested soccer-ball carbon configurations – fullerenes – might well be the source. In 1994 Bernard Foing & Pascale Ehrenfreund predicted and found two diffuse interstellar bands near 1 μm caused by the Fullerene ion C60+ but these could not be confirmed in the lab. In 2016 John Maier and Ewen Campbell in Basel succeeded in producing credible lab profiles and found additional bands.
