The diagram illustrates how two points on a droplet surface can scatter light and act as sources of outgoing spherical waves. The scattered waves overlap and interfere. Where wave crests of the same sign coincide the light intensity is increased. Where the waves have opposite amplitudes they destructively interfere to give low intensity. Scattered light from the whole droplet surface plus smaller contributions from reflected and transmitted waves combine to form a diffraction pattern - a…

The Sword of Orion - the three stars that make up the weapon hanging off the belt of this famous celestial hunter. The image showcases the amazing mix of physical and optical processes including atomic emission, Rayleigh scattering, reflection and absorbtion of light, that go on in this star forming region to create this kaleidescope of colours and details.

Located some 1300 light-years away in the constellation of Carina (The Keel of the ship Argo). It is informally known as the Wishing Well Cluster, as it resembles scattered silver coins which have been dropped into a well, It was the first target to be observed by the NASA/ESA Hubble Telescope. (May 1990) The stars that with moderate masses are still shining brightly with blue-white colors, but the more massive ones have already exhausted their supplies of hydrogen becoming red giant stars.

Reflection Nebula IC426. IC 426 is a reflection nebula in the constellation of Orion. Reflection nebulae often look a ghostly bluish color because they reflect scattered light from bright stars nearby (the red light is absorbed by dust in the nebula). Mintaka, the westernmost star in the belt of Orion, is thought to be the star illuminating IC 426. credit line: T. A. Rector/University of Alaska Anchorage, H. Schweiker/WIYN and NOAO/AURA/NSF
