Evidence for crystalline water and ammonia ices on Pluto's satellite charon. (1/2)
Observations have resolved the satellite Charon from its parent planet Pluto, giving separate spectra of the two objects from 1.0 to 2.5 micrometers. The spectrum of Charon is found to be different from that of Pluto, with water ice in crystalline form covering most of the surface of the satellite. In addition, an absorption feature in Charon's spectrum suggests the presence of ammonia ices. Ammonia ice-water ice mixtures have been proposed as the cause of flowlike features observed on the surfaces of many icy satellites. The existence of such ices on Charon may indicate geological activity in the satellite's past.

(+info)I'm sorry for any confusion, but "Pluto" is not a term used in medical definitions. It is the ninth planet from the Sun in our solar system, according to its discovery in 1930. However, in 2006, the International Astronomical Union (IAU) redefined the definition of a planet and Pluto did not meet all the criteria, so it's now classified as a "dwarf planet."
If you have any medical concerns or questions, I would be happy to help if you could provide more information!
Ultraviolet (UV) therapy, also known as phototherapy, is a medical treatment that uses ultraviolet light to treat various skin conditions. The UV light can be delivered through natural sunlight or artificial sources, such as specialized lamps or lasers.
In medical settings, controlled doses of UV light are used to target specific areas of the skin. The most common type of UV therapy is narrowband UVB (NB-UVB) phototherapy, which uses a specific wavelength of UVB light to treat conditions such as psoriasis, eczema, vitiligo, and dermatitis.
The goal of UV therapy is to reduce inflammation, slow skin cell growth, and improve the overall appearance of the skin. It is important to note that while UV therapy can be effective in treating certain skin conditions, it also carries risks such as skin aging and an increased risk of skin cancer. Therefore, it should only be administered under the supervision of a qualified healthcare professional.
