Astronomy refers to “the study of objects and matter (e.g. stars Josh Richardson Youth Jersey , planets, comets and galaxies) outside the Earth’s environment and of their physical and chemical properties”. The word astronomy (from the Greek words astron “star” and -nomy from nomos, “law” or “culture”) literally means “law of the stars” (or “culture of the stars” depending on the translation). There are 1000’s of words or definitions that you will find once you start looking into astronomy. What are the 10 definitions as a beginner you most need to know?
1. STAR: a self-heating ball of glowing gas. The Sun is the star nearest the Earth which powers life on Earth. 2. PLANETS: a large, round object orbiting a star. Earth is the planet we live on and is the third planet from the Sun. The other 7 planets in our solar system are called: Mercury, Venus Alonzo Mourning Youth Jersey , Mars, Saturn, Jupiter, Uranus and Neptune. There used to be a ninth planet called Pluto but this is now classed as a dwarf planet. 3. MOON: a natural satellite – an object orbiting a planet. Earth has one moon, though there are hundreds in our solar system. 4. COMET: a space snowball made of dust Goran Dragic Youth Jersey , rock and ice that orbits the Sun. Comets have tails when they are near the sun. 5. GALAXY: a large system of stars, gas, dust and empty space that rotates but is held together by gravity. Earth and its solar system are part of a galaxy called the Milky Way. 6. ASTEROID: a minor planet, actually just a giant rock, usually one that circles the Sun. There are hundreds of thousands in our solar system and more are being discovered all the time. 7. UNIVERSE: Everything! The Earth and its Moon Hassan Whiteside Womens Jersey , the Sun, the planets of the solar system, and all the galaxies – even things we haven’t yet discovered. Experts believe it’s just under 14 billion light years old. 8. BLACK HOLE: an area with a gravitational pull so strong that it sucks in anything that comes in too close. 9. SOLAR SYSTEM: The planets, moons, dwarf planets Dion Waiters Womens Jersey , comets, asteroids and dust that orbit the Sun, held by its gravity. 10. GRAVITY: the attraction between everything in the Universe. Gravity makes Earth and the other planets in the solar system orbit the Sun, and the moon rotate around the Earth.
Astronomers are people who study our Universe and they use telescopes to observe the night sky. An observatory is any place used to look into space. Optical observatories have a dome, often in a high-up location Dwyane Wade Womens Jersey , housing a telescope. The roof can be opened to look at the sky. There are also radio observatories with big dishes and space based observatories – telescopes floating in space.
Distributed Temperature Sensing (DTS) Market Application, Manufacturers, Regions & forecast to 2022

According to the new market research report “Distributed Temperature Sensing (DTS) Market by Operating Principle (OTDR, OFDR) Josh Richardson Womens Jersey , Fiber Type (Single-Mode, Multi-Mode), Application (Oil & Gas, Power Cable Monitoring, Fire Detection Alonzo Mourning Womens Jersey , Process & Pipeline Monitoring) and Geography – Global Forecasts to 2022″, was valued at USD 484.7 Million in 2015 and is expected to reach USD 811.5 Million by 2022, at a CAGR of 7.66% between 2016 and 2022. The major factors driving the growth of this market include the increasing demand for DTS systems for monitoring purposes in hostile working conditions wherein humans cannot reach, high reliability of DTS systems as they can be deployed over long distances, and increasing need for improved safety systems.
鈥淢arket for optical time domain reflectometry (OTDR) operating principle-based DTS systems expected to grow at the highest rate during the forecast period鈥?p> OTDR is the most widely used technology and has been in use since the inception of DTS systems. OTDR-based DTS systems help in providing a robust measurement and are less susceptible to issues such as reflections and bends in the fiber and accessories. The technology utilizes the time of flight principle to measure the backscattered light during the Rayleigh scattering and Fresnel reflecting in the optical transmission generated by a narrow laser pulse. The market for OTDR-based DTS systems is expected to grow at the highest rate during the forecast period.

鈥淥il & gas applications to hold the highest size of the DTS market between 2016 and 2022鈥?p> The DTS technology has become an integral part of the oil & gas industry. It helps in continuous Goran Dragic Womens Jersey , real-time downhole monitoring to optimize the operational and economic performances of the assets. This enables the reservoir engineers to gain a better understanding of the injection and production dynamics and accordingly optimize the production and improve recovery leading to improved profits. Hence, there is an increasing focus on adopting the technology for improving the productivity of brownfield operations. The analysis of the data collected by the DTS system can provide additional information on the behavior of the wells such as the flow volume within a particular section of the wells.
