style=\"color: #ff0000\"><strong>https:\/\/youtu.be\/7nT7JGZMbtM<\/strong><\/span><\/p>\n<p style=\"text-align: justify\">Webb Space Telescope<br \/>\nPosted byLaura DattaroNovember 28, 2011<\/p>\n<p style=\"text-align: justify\">On Thursday, November 17, 2011, the House and Congress came to an agreement for the fiscal year 2012 budget that includes funding for NASA and approves the full requested funding for the James Webb Space Telescope (JWST), the successor to the magnificent Hubble Space Telescope. The Webb, which came under fire in July 2011 when the House proposed cutting its funding entirely, will receive $529.6 million, the amount required for it to stay on track for its planned 2018 launch.<\/p>\n<p style=\"text-align: justify\">Here are five cool things \u2013 which you might not know \u2013 about the JWST project.<\/p>\n<p style=\"text-align: justify\">1. The James Webb will unfold in space. It\u2019s being launched on an Ariane 5 rocket, provided by the European Space Agency (ESA). But because of its massive size \u2014 it\u2019s as big as a tennis court and about 40 feet (12 meters) high \u2014 it must be folded up for the trip. Many features of the telescope, such as the hexagonal shape of the mirrors, were designed to enable the unfolding process. Check out the video below for a glimpse of how Webb\u2019s unfolding will take place.<\/p>\n<p style=\"text-align: justify\">2. The Webb will be nearly 1 million miles from Earth. To be exact, it\u2019ll be 940,000 miles (about 1.5 million kilometers) from Earth.<\/p>\n<p style=\"text-align: justify\">Webb will orbit at the Second Lagrangian Point. Credit: NASA<br \/>\nIt\u2019s being sent to what\u2019s known as the L2 \u2013 the second Lagrangian point in the Earth\/sun system. The Lagrangian points are named for Joseph Louis Lagrange, who realized that there would be stable or semi-stable points in the vicinity of every two orbiting bodies in space. In other words, every time you have two orbiting bodies, you also get five Lagrangian points. At these points, a third body can maintain a relatively stable orbit without the heavy usage of thrusters and propellants. In this case, the sun and Earth are the two bodies in space. The Webb Telescope will orbit the L2 point in the Earth\/sun system, which means it will follow Earth around the sun, always in a straight line with the Earth and sun. Its orbit will be far from Earth \u2013 beyond the moon\u2019s orbit. For comparison, the Hubble Space Telescope is 380 miles away in low Earth orbit.<\/p>\n<p style=\"text-align: justify\">3. The Webb Telescope\u2019s 18 mirrors are coated in a thin layer of 24-karat gold. Webb\u2019s purpose is to read infrared light, the wavelength of light that is emitted by the farthest objects in the universe. Gold reflects red light better than other materials, making the mirror 98 percent reflective, rather than the 85 percent achieved by ordinary mirrors.<\/p>\n<p style=\"text-align: justify\">Webb<br \/>\n4. The Webb Telescope\u2019s science instruments will operate at temperatures near absolute zero, the theoretical temperature at which all molecular and atomic motion ceases.<\/p>\n<p style=\"text-align: justify\">Webb<br \/>\nEverything that exists emits infrared radiation, which is produced from the vibration of atoms. The colder something is, the less infrared it emits. Because Webb is designed to work in the infrared, but emits infrared itself, it must be kept as cold as possible to keep its interference with itself at a minimum. Webb\u2019s massive sunshield divides the telescope into a hot side, with temperatures around 185 degrees F, and a cold side, around -388 degrees F, or 40 Kelvin. In contrast, the coldest temperature ever recorded on Earth was -129 degrees F.<\/p>\n<p style=\"text-align: justify\">5. Planning for the Webb telescope began in 1995. Just five years after Hubble launched, scientists at the Space Telescope Science Institute (STScI) in Baltimore, Md., first envisioned what its successor would look like, knowing it would take many years to bring this vision to fruition. Now the Webb is scheduled to be launched in 2018, and it\u2019s a safe bet that astronomers soon will begin imagining an instrument to extend our vision with a telescope even grander and more powerful than the Webb.<\/p>\n<p style=\"text-align: justify\">For more information about the \u2018scope and its science, visit its web site, or check out STScI on Facebook.<\/p>\n<p style=\"text-align:
