Due to the fact that the essential oils are made out of hydrocarbons (mostly aliphatic), most of them will be flammable. Therefore, when an orange peel or the peel of other citrus fruit is squeezed over a flame, it is allowed for the juices from the peel to come in contact with the flame; then, the essential oils ignite and burn.

One of the big mysteries in astronomy is how galaxies grow and evolve over time. Collisions between galaxies are thought to be key events that shape their development. A stunning collection of 59 new images of colliding galaxies has been released to mark the 18th anniversary of the NASA/ESA Hubble Space Telescope. They give us a unique insight into how galaxies collide to form larger galaxies.

An experiment showing burning of sulfur in oxygen. A flow-chamber joined to gas washing-bottle (filled with solution of methyl orange) is being used. The product is sulfur dioxide (SO2) with some traces of sulfur trioxide (SO3). The 'smoke' that exits the gas-washing bottle is, in fact, a sulfuric acid fog generated in a reaction represented by: :SO3(g) + H2O(l) = H2SO4(aq). The oxides are acidic, as can be witnessed by the colour change of the indicator.

A video of a galaxy forming in an astrophysical simulation.
Since our Universe moves too slowly to watch, faster-moving computer simulations are created to help find out. This video from the IllustrisTNG simulations tracks gas from the early universe until today. As the simulation begins, ambient gas falls into and accumulates in a region of relatively high gravity. After a few billion years, a well-defined center materializes from a strange and fascinating cosmic dance. Gas blobs – some representing small satellite galaxies – continue to fall into and become absorbed by the rotating galaxy as the present epoch is reached and the video ends.
