NASA released a series of images from the new James Web Space Telescope (JWST) on Monday.
The new image took on an unprecedented depth – and was a dramatic improvement over similar images from the old Hubble Space Telescope.
JWST started on December 25, 2021. Hubble, which began 32 years ago in 1990, is six times more powerful and 100 times more powerful.
The image released on Monday shows a larger area and JWST has more details than Hubble.
It is taken with infrared sensors that have a spectrum that is different from a standard camera. In addition to performing better than Hubble, JWST works faster. Hubble took weeks to scan the deep space, but JWST covered the same space in 12 hours and 30 minutes.
Zoom in makes the comparison clearer. The images below compare the interpretation of the Hubble and JWST galaxies of SMACs 0723, as seen 4.6 billion years ago.
The huge time limit is a measure of how far light travels through space telescopes.

This force, called gravity lensing, is of particular interest to astronomers because the gravitational pull of the galaxies distorts the distant galaxies.
Examples of distorted light in galaxies can be seen below.

Cosmologist Katie Mack describes the gravitational lens in detail in the video below.
JWST aims to take a deeper look than ever before. Its power helps to fill a mysterious gap in the history of the universe – the first 400 million years after the Great Depression, according to Insider Morgan McAffal-Johnson.
It requires planets that accommodate life outside of our solar system.
More images from JWST are expected to be released soon, by NASA.
The following pictures show these zones.
- Carina Nebula: One of the largest and brightest nebulae in the sky, about 7,600 light-years away, which is a star-studded constellation.
- WASP-96b (Spectrum) ፡ Complex-WASP-96 b is a giant planet, mainly composed of gas outside the solar system.
- The southern ring of the nebula is a rising cloud of gas, orbiting a star about 2,000 light-years away from Earth.
- Stephanie Quinet’s Pulse is the first compact galaxy in the constellation Pegasus, discovered in 1877, about 290 million light-years away.
