The supplement explains how telescopes use mirrors to gather and focus light, why they transformed astronomy, and what infrared, spectroscopy, cameras, and spectrometers enable. It highlights key Webb components—mirror design, sunshield, and cryocooler—and describes launch goals from French Guiana, aiming to observe early galaxies and measure redshift to reveal cosmic distances.","Sponsored  \nEducational Materials  \nSupplement to Scholastic magaz ines .

It’s mind-boggling—but cool! For as long as humans have existed, we have been  \nmesmerized by the universe and the questions it stirs up: How big is the universe? Is there life on other planets? How did the universe even begin—and is it changing?  \nRead on to find out how an amazing team of diverse   \nscientists are working together to find answers.  ~~ ~~~~ ~~   \nA CLOSER LOOK  \nOne of the oldest ways of exploring our galaxy is through the use of telescopes. When you were little, you may have made pretend telescopes out of paper towel rolls and aimed them atthe ceiling. Real telescopes use curved mirrors to gather and focus light from the night sky.  \nThe first known telescope to be pointed at the sky was designed in 1609 by an Italian scientist known today by his firstname, Galileo. He was able to detect moons orbiting Jupiter, leading him to the conclusion that not all celestial objects revolve around Earth—upending astronomy at the time.  \nOver time, astronomers and scientists built bigger, more complex instruments to explore space. More sophisticated  \ntelescopes have led to the  discovery of fundamental facts about our universe. Before telescopes, close observation led to theories that planets orbit (or go around) our Sun, but telescopes proved it. Telescopes demonstrated that stars are  \n“I was always fascinated by extremes in the universe, places where we reach the end of our knowledge.”  \n—Nora Luetzgendorf, Telescope Scientist  \nnot solid, they are spheres of gas—and our closest star is the Sun. Telescopes also proved that there are hundreds of billions of stars in our galaxy, and hundreds of billions of galaxies in the universe! More sensitive telescopes showed us that practically every star has at least  \n2 GAZING ACROSS GALAXIES  \none planet around it—and many have multiple planets, like our solar system. Telescopes also helped us uncover the scale of the solar system—how big each planet is, and how far it is from other planets and the sun.  \nBut how did the first stars and planets form? Are there other habitable planets out there?  \nNASA's Webb space Telescope  \nMIRROR This perfectly smooth mirror consists of 18 separate pieces that can unfold after launch to about 21 feet in length. Each mirror is made of a lightweight yet strong material called beryllium, which can hold its shape in the extreme cold of space. The mirrors are coated in a microscopically thin layer of gold to better reflect infrared light.  \nSUNSHIELD  \nThe five-layered sunshield is the size of a tennis court! Its job is to minimize the heat from the sun—by more than a million times!  \nCRYOCOOLER Basically a sophisticated refrigerator in space, the cryocooler behind the mirror uses helium gas and advanced machinery to cool the MIRI (one of the instruments that observes space) to-448 degrees Fahrenheit. (That’s COLD!)  \nSky  \nchange everything.  \nAre we alone in the universe? To search for answers, NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA) brought together a diverse group of scientists and engineers—from all backgroundsand areas of ex","cbCaiqt10snJDm71","https://ap.wps.com/l/cbCaiqt10snJDm71","pdf",2620436,1,8,"English","en",105,"# Gazing Across Galaxies\n## A CLOSER LOOK\n## Eye in the Sky\n## The Next Frontier","[{\"question\":\"What is the main goal of the Webb Space Telescope mentioned in the supplement?\",\"answer\":\"The Webb Space Telescope is designed to see much farther than previous telescopes, recording light from billions of years ago to help answer questions about the universe and whether other habitable planets exist.\"},{\"question\":\"How do telescopes change our understanding of astronomy?\",\"answer\":\"Telescopes gather focused light using curved mirrors, allowing astronomers to confirm that planets orbit the Sun and to measure vast numbers of stars and galaxies in the universe.\"},{\"question\":\"Why is infrared light important for Webb?\",\"answer\":\"Infrared waves are invisible to the human eye, but objects that have heat emit infrared radiation, making them detectable by Webb and useful for studying distant space.\"},{\"question\":\"What does redshift measurement help scientists determine?\",\"answer\":\"By measuring redshift—when light waves turn redder as they travel farther—scientists can estimate distances between galaxies and between other galaxies and our own.\"}]","GAzing Across Galaxies -
