Five Major Differences Between James Webb telescope Vs Hubble telescope
The James Webb Telescope, which was described as NASA’s second child in 2000, has entered orbit today around Lagrange Point 2, also known as L2. It is around one million miles from Earth. The massive space telescope is set to orbit the Sun in line with Earth. In contrast, the Hubble telescope is located about 350 miles from Earth. Let’s examine how these two telescopes differ.
Hubble began its mission in April in low-Earth orbit. Hubble has been in rotation for over 30 years, and has been able to help us gain an understanding of the nature of the universe by taking stunning images. The James Webb Telescope was announced in December 2021. It is designed to detect objects ten times more faint than Hubble.
Klaus Pontoppidan, before the launch of Webb, in an event in which he announced that the images captured from Webb would be superior to the photos taken by Hubble. The scientist also claimed that images would be distinct due to their different wavelengths’. In addition, Webb can and has been specifically designed to detect infrared night, resulting in unique, amazing images. Hubble is the opposite and can see the light in ultraviolet and optical wavelengths.
Although the James Webb telescope is around one million miles away, it and Hubble are about 350 miles away. Webb must be more excellent than Hubble to capture the light wavelengths in the infrared. Webb must, therefore, be able to be protected from Sun, Earth and Moon’s infrared radiation.
The South Atlantic Anomaly
The South Atlantic Anomaly is a tiny nick in the magnetic field of Earth’s magnetic field, which can cause damage to satellites. Hubble travels through the weak spot around 15 per cent often. The problem is that Webb does not come into contact with this anomaly.
Webb is predicted to extend beyond Hubble’s scope and show the first light of the universe’s galaxies and stars, showing how stars appeared 13.7 billion years ago.
