Biologists report the discovery of the oldest known skin, fossilized about 289 million years ago, and possibly the skin from an ancient reptile. [ 22 ] [ 23 ] Scientists report the discovery of Tyrannosaurus mcraeensis , an older species of Tyrannosaurus that lived 5-7 million years before Tyrannosaurus rex , and which may be fundamentally ...
The product of Simon Newcomb's J1900.0 mean tropical year of 31 556 925.9747 ephemeris seconds and a speed of light of 299 792.5 km/s produced a light-year of 9.460 530 × 10 15 m (rounded to the seven significant digits in the speed of light) found in several modern sources [10] [11] [12] was probably derived from an old source such as C. W ...
Each entry below is an outline, an introduction to a subject structured as a hierarchical list of the essential points. Each of these outlines focuses on a natural science. Along with Wikipedia:Contents/Outlines, the outlines on Wikipedia form an all-encompassing
A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
The following outline is provided as a topical overview of science; the discipline of science is defined as both the systematic effort of acquiring knowledge through observation, experimentation and reasoning, and the body of knowledge thus acquired, the word "science" derives from the Latin word scientia meaning knowledge. A practitioner of ...
Astronomers report the discovery of giant "geysers" of charged particles emanating from the core of the Milky Way Galaxy. These outflows, which extend as far as 50,000 light-years from the galactic plane, are thought to be fuelled by intense star formation. [3] [4] LG Electronics releases the first commercial OLED television.
The following outline is provided as an overview of and topical guide to astronomy: Astronomy – studies the universe beyond Earth, including its formation and development , and the evolution, physics , chemistry , meteorology , and motion of celestial objects (such as galaxies , planets , etc.) and phenomena that originate outside the ...
The first aurora beyond the Solar System is reported, on a brown dwarf 18 light years from Earth. [323] Astronomers report the discovery of HD 219134 b, a rocky exoplanet, due to its size of 1.6 Earth and density of 6 g/cm 3, that is the closest such exoplanet to Earth, at 21.25 light-years away.
