This image is part of a Hubble Space Telescope survey for low-mass stars, brown dwarfs, and planets in the Orion Nebula. Each symbol identifies a pair of objects, which can be seen in the symbol’s center as a single dot of light. Special image processing techniques were used to separate the starlight into a pair of objects. The thicker inner circle represents the primary body, and the thinner outer circle indicates the companion. The circles are color-coded: red for a planet; orange for a brown dwarf; and yellow for a star. Located in the upper left corner is a planet-planet pair in the absence of a parent star. In the middle of the right side is a pair of brown dwarfs. The portion of the Orion Nebula measures roughly four by three light-years. Credit: NASA , ESA, and G. Strampelli (STScI)

Thermal measurement of nanopolyethylene (nanoPE) and various textile samples. (A) experimental setup of textile thermal measurement. The heating element that generates constant heating power is used to simulate human skin, and the “skin temperature” is measured with the thermocouple. Lower skin temperature means a better cooling effect. (B) Thermal measurement of bare skin, nanoPE, cotton, and Tyvek. NanoPE has a much better cooling effect than that of cotton and Tyvek because of its infrared (IR)-transparency. (C) Thermal imaging of bare skin and the three samples. Only nanoPE can reveal the H-shape metallic pattern because of its IR-transparency. Photo by Stanford University.
