What is an Emulsion? In the world of cosmetics, âemulsionâ is a common term. Most lotions and creams are emulsions. Mix two fluids that usually donât mix together well and you have an emulsion. Think oil and water getting along happily. You can also think of mayonnaiseâvinegar water mixed with oil (usually soybean, but we recommend looking for alternatives) whipped into a creamy spread. How do they do it?
Why is Pluto no longer a planet? In August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of dwarf planet.. This means that from now on only the rocky worlds of the inner Solar System and the gas giants of the outer system will be designated as planets.
Pluto didn't become a dwarf planet...it was RE-CLASSIFIED as a dwarf planet. Pluto has always been the same celestial body it has always been. Re-classifying it doesn't change anything about it.
