While metastasis of common sunlight-induced squamous cell carcinoma is unusual, lesions more likely to metastasize are lesions of the lip or ear, lesions that recur after previous therapy, lesions at the site of a burn and those that are more deeply invasive.
The Great Dark Spot was one of a series of dark spots on Neptune similar in appearance to Jupiter's Great Red Spot. GDS-89 was the first Great Dark Spot on Neptune to be observed in 1989 by NASA's Voyager 2 spaceprobe. Like Jupiter's spot, Great Dark Spots are anticyclonic storms.
