Another key difference between the Webb telescope and other telescopes is its location. The Webb telescope will be positioned at a point in space called the second Lagrange point, or L2. This point is located about 1.5 million kilometers (930,000 miles) from Earth, on the opposite side of the planet from the sun. By placing the telescope at L2, it will be shielded from the heat and light of the sun, which can interfere with its delicate instruments. Additionally, being located away from Earth's atmosphere means that the Webb telescope will be able to observe the universe more clearly, without the distortion caused by the atmosphere.
Overall, the Webb telescope's size, infrared capabilities, and location at L2 make it a unique and powerful tool for studying the universe.
What the Webb Telescope will study
The Webb telescope has three primary scientific goals: to study the first galaxies and stars that formed after the Big Bang, to study the atmospheres of exoplanets, and to study the formation of stars and planetary systems. Let's take a closer look at each of these goals.
