Freckle regular use of sunblock can inhibit their development. Liver spots (also known as sun spots and lentigines) look like large freckles, but they form after years of exposure to the sun. Liver spots are more common in older people. Freckle Freckles are clusters of concentrated melaninized cells which are most easily visible on people with a fair complexion. Freckles do not have an increased number of the melanin-producing cells, or melanocytes, but instead have melanocytes that overproduce melanin granules (melanosomes) changing the coloration of the outer skin cells (keratinocytes). As such, freckles are different from lentigines and moles, which are
Bright spots on Ceres Bright spots on Ceres Several bright surface features (also known as faculae) were discovered on the dwarf planet Ceres by the "Dawn" spacecraft in 2015. The brightest cluster of spots ("Spot 5") is located in an crater called Occator. The largest and brightest component of the cluster is in the center of the crater, with dimmer spots located towards this crater's eastern rim. Early in the orbital phase of the "Dawn" mission, the high albedo of these spots was speculated to be due to some kind of outgassing, and subsequent closer images helped scientists determine that it is a material
