How the Webb telescope compares with the Hubble.

The Webb telescope’s most important mirror is 6.5 meters in diameter, compared with Hubble’s, which is 2.4 meters, offering Webb about 7 occasions as considerably mild-collecting capacity and consequently the potential to see further into the past.

Another important distinction is that Webb is geared up with cameras and other instruments delicate to infrared, or “heat,” radiation. The growth of the universe causes the gentle that would commonly be in wavelengths that are seen to be shifted to for a longer period infrared wavelengths that are usually invisible to human eyes.

On the other hand, the Hubble telescope is in very low Earth orbit, wherever astronauts could visit and repair things that have broken or worn out, or set up new, extra potent devices on it. Those modifications extended its lifetime a long time past the authentic estimates.
