A supernova is a stellar explosion that creates an extremely luminous object that is initially made of plasma—an ionized form of matter. A supernova may briefly outshine its entire host galaxy before fading from view over several weeks or months. During this brief period of time, the supernova radiates as much energy as the Sun would emit over about 10 billion years. The explosion expels much or all of a star's material at a velocity of up to a tenth the speed of light, driving a shock wave into the surrounding interstellar gas. This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant. There are several types of supernovae and at least two possible routes to their formation. A massive star may cease to generate energy from the nuclear fusion of atoms in its core, and collapse under the force of its own gravity to form a neutron star or black hole. Alternatively, a white dwarf star may accumulate material from a companion star (either through accretion or a collision) until it nears the Chandrasekhar limit of roughly 1.44 times the mass of the Sun, at which point it undergoes runaway nuclear fusion in its interior, completely disrupting the star. On average, supernovae occur about once every 50 years in a galaxy the size of the Milky Way and play a significant role in enriching the interstellar medium with heavy elements. Furthermore, the expanding shock waves from supernova explosions can trigger the formation of new stars. (more...)

A dromedary or one-humped camel (Camelus dromedarius) in the Australian Outback. Estimated populations of Australian feral camels are in the hundreds of thousands, and this is now the world's only population of dromedaries exhibiting wild behaviour. Thousands of camels were imported into Australia between 1840 and 1907 to open up the arid areas of central and western Australia. They were used for riding, and as draught and pack animals for exploration and construction of rail and telegraph lines; they were also used to supply goods to remote mines and settlements. Their impact on the environment is not as bad as that of other introduced pests in Australia. They prefer to eat trees and plants that local wildlife dislike; only 2% of their diet is grass.

Featured list: Timeline of chemistry
An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory. Timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed mankind's understanding of the composition of matter and of the interactions thereof, the modern science known as chemistry. The history of chemistry in its modern form is often considered to begin with the English scientist Robert Boyle, though its roots can be traced back to the earliest recorded history. Pre-17th century Aristotle (384-322 BCE) c. 3000 BCE Egyptians formulate the theory of the Ogdoad, or the “primordial forces”, from which all was formed.

Pre-17th century

Aristotle (384-322 BCE)

c. 3000 BCE: Egyptians formulate the theory of the Ogdoad, or the “primordial forces”, from which all was formed. These were the elements of chaos, numbered in eight, that existed before the creation of the sun.^[1]

c. 1900 BCE: Hermes Trismegistus, semi-mythical Egyptian adept king, is thought to have founded of the art of alchemy.^[2]

c. 1200 BCE: Tapputi-Belatikallim, a perfume-maker and early chemist, was mentioned in a cuneiform tablet in Mesopotamia.^[3]

17th and 18th centuries

1605: Sir Francis Bacon publishes The Proficience and Advancement of Learning, which contains a description of what would later be known as the scientific method.^[4]

1605: Michal Sedziwój publishes the alchemical treatise A New Light of Alchemy which proposed the existence of the "food of life" within air, much later recognized as oxygen.^[5]

1615: Jean Beguin publishes the Tyrocinium Chymicum, an early chemistry textbook, and in it draws the first-ever chemical equation.^[6]

1637: René Descartes publishes Discours de la méthode, which contains an outline of the scientific method.^[7]

1648: Posthumous publication of the book Ortus medicinae by Jan Baptist van Helmont, which is cited by some as a major transitional work between alchemy and chemistry, and as an important influence on Robert Boyle. The book contains the results of numerous experiments and establishes an early version of the Law of conservation of mass.^[8]
