How many light years away is the James Webb telescope?

Did you know that the James Webb Telescope is like a time machine as much as it is an observation machine, the farther the telescope sees in space, the farther it looks in time, because the images from distant objects take a long time to reach us, and therefore, the image we see of the galaxy that 13.6 billion light-years away isn't a picture of how it would look today, but what it looked like 13.6 billion years ago, during the early universe.

And NASA revealed that the infrared capabilities of the web mean that it can “see past time” within only 100-200 million years from the astronomical phenomenon called the Big Bang, which is due to the emergence of the universe, allowing it to take pictures of the first stars that shine in the universe. More than 13.6 billion years ago.

According to "time" website, the James Webb telescope's geometry differs from other telescopes as well as its location in space, as the Webb telescope operates with the infrared spectrum, a wavelength of light that exceeds the visible spectrum and is a measure of heat more than light.

The James Webb Telescope can see 13.6 billion light-years away, as infrared radiation cuts off the interference that visible light from dust and gas in deep space may cause, and Webb needs to be protected from stray heat, which would distort its infrared optics. For this reason, the telescope must remain extremely cold, which is what makes some of the architecture unusual.

Webb's main mirror is 6.5 meters (21.6 feet) wide and is made of 18 hexagons, each of which can be adjusted in seven different axes with nanometer precision allowing the mirror to focus on maximum detail and clarity.

The telescope is located 1.6 million kilometers (one million miles) from the planet, where it maintains its station at what is known as the Lagrange point, a spot in space where the gravity of the Earth and the Sun cancel each other out, allowing objects to orbit the invisible point as if they were orbiting a solid object like a planet.
