The best masterpiece in the history of the Webb telescope, a majestic 123 million pixel “creation column” | Forbes Japan (Forbes Japan)

What I predicted in January of this year has finally happened. The James Webb Space Telescope (JWST) has sent us the best images ever.

The work, titled Pillars of Creation, is a re-capture of nearly identical regions of space captured in the 1990s with the Hubble Space Telescope (HST).

This 123 megapixel (8422 x 14.589 pixels) vertical image is available in TIFF format as the original 163.4 MB full size image.DownloadIt is possible.In addition, in the browserZoomable versionand a 1MB screen in JPEG format, there are many wallpaper sizes suitable for desktop computers, tablets and smartphones.

The new JWST vs. HST comparison image clearly shows how the capabilities of modern infrared space telescopes differ from older visible/ultraviolet space telescopes. This is no surprise.

But JWST’s “creative pillars” are amazing.

HST 1995An original copyAnd the 2014 upgraded version of the near-infrared is still stunning, allowing us to see “fingers” of interstellar gas and dust in the Eagle Nebula. It is located in the constellation Serpens, 7000 light years away. It’s where new stars form in dense clouds of cold gas and dust.

The scene that JWST sees is different.

In the JWST version, red balls can be seen on the tips of the finger-like tendrils of cool interstellar dust and dust. This red orb is a protostar, a very young nascent star that can only be seen in JWST. In addition to its beauty, the gas and dust cloud looks almost transparent.

Finally, here’s a side-by-side image of HST (left) and JWST (right), showing the difference. The visible-light HST image shows the column dark, while the JWST near-infrared image shows the same red and transparent column.

JWST is the most ambitious and complex space telescope ever built, with a massive 6.5-meter primary mirror capable of detecting the dim light of distant stars and galaxies. The telescope is specially designed to detect infrared radiation emitted by distant stars, planets, gas and dust clouds.

Observations are made about 1 million miles (1.6 million km) from Earth, but they can see light from the first stars and the oldest galaxies.

I wish a clear sky and big eyes.
