The ability to use atmospheric nitrogen to support more widespread life was thought to have appeared roughly 2 billion years ago. Now research from the University of Washington looking at some of the planet's oldest rocks finds evidence that 3.2 billion years ago, life was already pulling nitrogen out of the air and converting it into a form that could support larger communities.

Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...
The spectroheliograph captures a photographic image of the Sun at a single wavelength of light. The wavelength chosen usually coincides with a spectral wavelength of one of the chemical elements present in the Sun. George Ellery Hale and Henri-Alexadre Deslandres developed I independently in 1890 and was further refined in 1932 by Robert R. McMath to take motion pictures. It operates by using a prism together with a narrow slit that passes a single wavelength. The light focuses on a...
Fermium is a synthetic, radioactive metallic element. It has the symbol Fm and atomic number 100. It is an element in the actinide series. It is named after nuclear physicist Enrico Fermi. Fermium became the eighth transuranic (having an atomic number greater than 92) element discovered. It was first discovered in 1952 by a team of scientists led by Albert Ghiorso. They found fermium-255 in debris of the first hydrogen bomb explosion from Operation Ivy. Fermium-255 was created when...
Europium is a chemical element with the symbol Eu and atomic number 63. Europium is named after the continent Europe. It is the most reactive of the rare earth elements. It rapidly oxidizes in air. Europium ignites in the air at around 302 degrees Fahrenheit. It is quite pliable (bendable). Although it was first discovered by Paul Ã‰mile Lecoq de Boisbaudran in 1890, it is usually credited to French chemist EugÃ¨ne-Anatole DemarÃ§ay, who suspected samples of the discovered samarium...
Erbium is a chemical element with the symbol Er and atomic number 68. Erbium is a rare, silvery-white metallic lanthanide (an element having an atomic number between 57 and 71). It is found solid in its natural state and is commonly found with several other elements in the mineral gadolinite. It is found in Ytterby, Sweden. Erbium was discovered by Carl Gustaf Mosander in 1843. Mosander separated yttria from gadolinite into three compounds he called erbia, terbia, and yttria. Erbia and...
