Scientists map sulfur residue on Jupiter’s icy moon Europa

The Hubble Space Telescope was used by a team led by the Southwest Research Institute to observe Jupiter's moon, Europa, at ultraviolet wavelengths, filling a "gap" in the various wavelengths used to observe this icy water world. The team's near-global UV maps show sulphur...

New optical tweezers can control luminescent colour using light pressure

One big stumbling block in the field of photonics is that of colour control. To control colour that is the wavelength of light emission, scientists would have to alter the chemical structure of the emitter or the concentration of the solvent. All of it...

Scientists explain mysterious finger-like features in solar flares

Scientists observed mysterious motions within a solar flare in 1999. This flare has bright energy erupting outwards from the Sun. It solar flare  also displayed a downward flow of motion. This looks like as if material was falling back towards the Sun. Scientists have described...

Study finds cadmium turns leafy green into purple

Leafy greens turn purple though humans cannot see it. It can be seen through advanced hyperspectral imaging. Scientists from Purdue have discovered this colour change in kale and basil stressed by cadmium. It is a heavy metal toxic to human and animal health. New detection...
