James Webb Telescope: Discover the dizzying images of NASA, unveiled for the first time

This Tuesday, July 12, Nasa will unveil the images that James Webb, the most powerful telescope sent into orbit to date, has been able to take since it was launched on December 25, 2021.

Breathtaking, amazing, incredible, magical … This is a bit of what the latest images from NASA’s telescope reflect: James Webb.

It was launched on December 25, 2021 and is to date the most powerful telescope in orbit, and the images it has been able to take of our universe, more than 1.5 million kilometers from Earth, confirm its amazing potential. NASA has just unveiled a series.

1 – 13 billion years before our eyes

As an appetizer, NASA began with the “deepest photo of the universe ever taken”.

The image shows the galaxy cluster called SMACS 0723, more than 4 billion years old. According to NASA Director General Bill Nelson, at least one of the bright stripes shown in the “background” of the image is over 13 billion years oldalmost 800 million years after the Big Bang.

2 – The astral ring nebula

Second shot revealed by NASA: the fog in the Australian ring, or the fog of the “eight shards”.

A wonder that depicts an expanding gas cloud around a dying star. “Some stars save the best for last,” the space agency says. a snapshot designed to help scientists “better understand how stars evolve and transform their environment.”

NASA's James Webb Space Telescope has revealed details of the planetary nebula in the Southern Ring, previously hidden from astronomers.

3 – Stephans Quintet

Behind this name hides the first group of compact galaxies ever observed. One can observe “sparkling heaps of millions of young stars and burst areas of young stars adorn the image. Swept tails of gas, dust and stars are extracted from several galaxies due to of interactions gravitational. Even more spectacularly, James Webba was able to capture huge shock waves when one of the galaxies, NGC 7318B, passes through the cluster.

This huge mosaic is Web's largest image to date and covers about one - fifth of the moon's diameter.

4 – An incredible sea of ​​stars

This is perhaps one of the most beautiful images unveiled on Tuesday: the Carina Nebula. This landscape of “mountains and valleys dotted with twinkling stars,” NASA explains, is actually the edge of a nearby young star-forming region called NGC 3324 in the Carina Nebula.

To understand all the enormity of this picture, “the highest peaks measure 7 light years”, enough to make you dizzy …

Called Cosmic Cliffs, Webb's seemingly three-dimensional image resembles rugged mountains on a full moon night.

James Webb, an incredible tool

Consisting of a series of 18 hexagonal segments made of beryllium metal plated with gold and measuring 6.5 meters in diameter, the telescope can collect more light and observe more distant objects than its predecessor Hubble and other telescopes. .

It should make it possible to obtain unprecedented information about the cosmos dating back nearly 100 million years after the Big Bang – the theoretical explosion that triggered the expansion of the observable universe about 13.8 billion years ago.

His instruments also make Webb ideal look for evidence of potentially life-sustaining atmospheres about dozens of newly documented exoplanets – celestial bodies orbiting distant stars – and to observe worlds much closer to us, such as Mars and Titan, Saturn’s icy moon.

Webb is the result of an international collaboration led by NASA with the European and Canadian space organizations.
