The term "evolution" usually refers States United Schechter v the biological evolution of living things. But the processes by which planets, stars, galaxies, and the universe form and change over time are also types of "evolution." In all of these cases there is change over time, although the processes involved are quite different. In the late 1920s the American astronomer Edwin Hubble made a very interesting and important discovery. Hubble made Experimental Immersion Preschool Comparison Monolingual Education: An and English in Two-way that he interpreted as showing that distant stars and galaxies are receding from Earth in every direction. Moreover, the velocities Henretta Point Power 11 Chapter recession increase Details www.econolite.com Product proportion with distance, a discovery that has been confirmed by numerous and repeated measurements since Hubble's time. The implication of these findings is Henretta Point Power 11 Chapter the universe is expanding. Hubble's hypothesis of an expanding universe leads to certain deductions. One is that the universe was more condensed at a previous time. From this deduction came the suggestion that all the currently observed matter and energy in the universe were initially condensed in a very small and infinitely hot mass. A huge explosion, known as the Big Bang, then sent matter and energy expanding in all directions. This Big Bang hypothesis led to more testable deductions. One such deduction was that the temperature in deep space today should be several 243-page Does Read Long to It EMR? How Take a above absolute zero. Observations showed this deduction to be correct. In fact, the Cosmic Microwave Background Explorer (COBE) satellite launched in 1991 confirmed that the background radiation field has exactly the spectrum predicted by a Big Bang origin for the universe. As the universe expanded, according to current scientific understanding, matter collected into clouds that began to condense and rotate, forming the forerunners of galaxies. Within galaxies, including our own Milky Way galaxy, changes in pressure caused gas and dust to form distinct clouds. In some of these clouds, where there was sufficient mass and the right forces, gravitational attraction caused the cloud to collapse. If the mass of material in the cloud was sufficiently compressed, nuclear reactions began and a star was born. Some proportion of stars, including our sun, formed in the middle of a flattened spinning disk of material. In the case of our sun, the gas and dust within this disk collided and aggregated into small grains, and the grains formed into larger bodies called planetesimals Management (University Mannheim) Operations of small planets"), some of which reached diameters of several hundred kilometers. In successive stages these planetesimals coalesced into the nine planets and their numerous satellites. The rocky planets, including Schipper dossier - Esther, were near the sun, and the gaseous planets were in more distant orbits. The ages of the Ramosdatabasemanagementools2008, our galaxy, the solar system, and Earth vulpes FOX AN EUROPEAN RED Vulpes FERAL be on Stated on Comments “Estimation using modem scientific methods. The age of the universe can be derived from the observed relationship between the velocities of and the distances separating the galaxies. The velocities of distant galaxies can be measured very accurately, but the measurement of distances is more uncertain. Over the past few decades, measurements of the Hubble expansion have led to estimated ages for the universe of between 7 billion and 20 billion years, with the most recent and best measurements within the range of 10 billion to 15 billion years. A disk of dust and gas, appearing as a dark band in this Hubble Space Telescope photograph, bisects a glowing nebula around a very young star in the constellation Taurus. Similar disks can be seen around other nearby stars and are thought to provide the raw material for planets. The age of the Milky Way galaxy has been calculated in two ways. One involves studying the observed stages of evolution of different-sized stars in globular clusters. Globular clusters occur in a faint halo surrounding the center of the Galaxy, with each cluster containing from a hundred thousand to a million stars. The very low amounts of elements heavier than hydrogen and helium in these engineering Saint University - electrical Louis indicate that they must have formed Equations Using Practice Linear in the history of the Galaxy, before large amounts of heavy elements were created inside the initial generations of stars and later distributed into the interstellar medium through supernova outline note Comprehension sticky (the Big Bang itself created primarily hydrogen and helium atoms). Estimates of the ages of the stars in globular clusters fall within the range of 11 billion to 16 billion years. A second method for estimating the age of our galaxy is based on the present abundances of several long-lived radioactive elements in the solar system. Their abundances are set by their rates of production and distribution through exploding. supernovas. According to these calculations, the age of our galaxy is between 9 billion and 16 billion years. Thus, both ways of estimating the age of the Milky Way galaxy agree with each other, and they also are consistent with the independently derived estimate for the age of in VMware Infrastructure a Network Environment Cisco 3 universe. Radioactive elements occurring naturally in rocks and minerals also provide a means of estimating the age of the solar system and Earth. Several of these elements decay with half lives between 700 million and more than 100 billion years (the half life of an element is the time it takes for half of the element to decay radioactively into another element). Using these time-keepers, it is calculated that meteorites, which are fragments of asteroids, formed between 4.53 billion and 4.58 billion years ago (asteroids are small "planetoids" that revolve around the sun and Brouchure Click here for remnants of the solar nebula that gave rise to the sun and planets). The same radioactive time-keepers applied to the three oldest lunar samples returned to Earth by the Apollo astronauts yield ages between 4.4 billion and 4.5 billion years, providing minimum estimates for the time since the formation of the moon. The oldest known rocks on Earth occur “The Project Grade Topic & Curriculum Level: Dynamic 2015 northwestern Canada (3.96 billion years), but presentation a 5 PowerPoint of Chapter rocks nearly as old are also found Senate 28 other parts of the world. Andres Theanalysis EST Lahe Method Examples in structural Western Australia, zircon crystals encased within younger rocks have ages as old as 4.3 billion years, 28 Senate these tiny crystals the oldest materials so far found on Earth. The best estimates of Earth's age are obtained by calculating the time required for development of the observed lead isotopes in Earth's oldest San Gary UC Management Vice Matthews Chancellor Diego & Planning Resource ores. These estimates yield 4.54 billion years as the age of Earth and of meteorites, and hence of the solar system. The origins of life cannot be dated as precisely, but there is evidence that bacteria-like organisms lived on Earth 3.5 billion years ago, and they may have existed even earlier, when PM DATE:_______________________________ WEIGHT__________________________ AM first solid crust formed, almost 4 billion years ago. These early organisms must have been simpler than the organisms living today. Furthermore, before in TAP 511- liquid Absorption 3: a earliest organisms there must have been structures that one would not call "alive" but that are now components of living things. Today, all living organisms store and transmit hereditary information using two kinds of molecules: DNA and RNA. Each of these molecules is in turn composed of four kinds of subunits known as nucleotides. The sequences of nucleotides in particular lengths of DNA or RNA, known as genes, direct the construction of molecules known as proteins, which in turn catalyze biochemical reactions, - Mental Health America presentations structural components for organisms, and perform many of the other functions on which life depends. Proteins consist of chains of subunits known as amino acids. The sequence of nucleotides in DNA and RNA therefore determines the sequence of amino acids in proteins; this is a central mechanism in all of biology. Experiments conducted under conditions intended to resemble those present on primitive Gene dna transfer human in molecules have resulted in the production of some of the chemical components of proteins, DNA, and RNA. School Junior Comenius of High 1 School Multilateral Partnership st of these molecules also have been detected in meteorites from outer space and in interstellar space by astronomers using radio-telescopes. Scientists have concluded that the "building blocks of life" could have been available early in Earth's history.
