Wabbu telescope was smashed by meteors?Yes, but it ’s not bad, I also put a new picture!

The Webb Wang Yuan Mirror came out with a new picture!

Just one month ago, in order to demonstrate the excellent observation performance of this infrared space telescope in different scientific goals, by the way, it proved that the nearly $ 10 billion was spent enough. The official announced several scientific images taken by Weibu. Show a new universe that has never been seen before (see the "Cosmic" Buyer Show ", ask you about $ billions of dollars worthless?").

And this time, the official official image has only one target celestial body, that is--

Wheel galaxy PGC 2248

The wheel galaxy is about 500 million light years away from the earth. It is located in the SCULPTOR in Nantian, named after the wheels that looks like an old carriage.

Scientists believe that a long time ago, the wheel galaxy was an ordinary large -scale vortex galaxy, similar to our galaxy. About 400 million years ago, it had a high -speed collision with another small galaxy that could not be seen in this picture. This incident changed the shape and structure of the wheel galaxy, making it the look we saw today.

Two ring -shaped structures are formed in the wheel galaxy: one bright inner ring revolves around the center of the galaxy, and the other colorful outer ring is frame the entire galaxy. The two rings expand from the center of the collision, just like the ripples caused by throwing a stone in the pond.

Due to these unique characteristics, astronomers classify it as "circular galaxy", which is much rare than a vortex galaxy such a galaxy.

However, despite the collision of galaxies, most of the characteristics of large vortex galaxies have been retained, including its rotary arm. They constitute a "spoke" between the inner ring and the outer ring, making the entire galaxy look more like the wheel of the old carriage.

In the first image of near -infrared and medium infrared synthesis, the rotary arm was displayed as bright red. The same bright red tone not only appears in the entire wheel galaxy, but also appears in the slightly smaller vortex galaxy above the left.

This color indicates the dust of the hydrocarbon in the galaxy, which is filmed by the Weibu telescope.

In the same goal, the Hubble Telescope was observed as early as 27 years ago. However, the Weibu Telescope uses its strong infrared observation capabilities to reveal a large number of details that have never been seen in this galaxy structure.

Infrared, it is essentially thermal radiation. It can penetrate the dust of the dust, so that Wabu can see the space area where the Hubble telescope cannot see through.

The latest images released by Webb not only distinguishes a single star in the stars on the outer ring of the wheel galaxy, but also shows the very young star group around the large quality black hole in the galaxy. detail.

For example, with the expansion of the outer ring outward, it pushes the dust and gas of the galaxy outward, which will cause the formation of stars. The area where the new star was born was displayed as a small blue dot in a near -infrared image, scattered in the entire galaxy, but it was particularly concentrated in the outer ring.

The image taken by the Webbu Telescope provides a new perspective, which lets us see the changes in the wheel's astrochemicals over the years.

From the comparison chart of the two generations of space telescope above, we can see that in just 27 years. Although the wheel galaxy itself has not changed significantly, it happens to appear in front of the galaxy in front of the wheel galaxy (in the red frame) A short distance.

The more obvious difference is that the Webu Telescope can see many farther farther galaxies behind it through the wheel galaxy.

This has greatly expanded the ability of human beings to look at the universe.

"Isn't Webb the hung?"

Shortly after the Webu Telescope announced the first batch of colorful pictures, a rumor began to circulate on social media. The intention was that the Webb Telescope has been hit by micro -stars many times, which has caused irreversible damage.

The rumored words and texts are all doubtful: Is it just after taking the first picture, and the US $ 10 billion Weibu telescope was smashed into scrapped?

In fact, the Weibu telescope was hit by a micro -stars at a high speed, and it was more than once. As of the first batch of scientific pictures, Weibu suffered at least 19 impacts.

Among them, the impact described as "the irreversible destruction" occurred between May 22-12, and a obvious concave was smashed on the 18th main lens of the Webb Wang Far Mirror. mark.

It looks serious? really. But in fact, large telescopes are far less fragile as ordinary people think.

Take an example of other telescope.

McDonald Astronomical Table of 107 -inch Telescope | McDonald Observatory

The McDonald Astronomical Observatory in the United States has a telescope with a caliber of 107 inches (about 2.7 meters). On February 5, 1970, a new employee who was recently employed was drunk, took a pistol into the observatory, and fired 7 shots towards the main mirror of the telescope. When he found that he couldn't break the main mirror, he climbed the hammer into the telescope again and smashed it at the main mirror.

Such a deliberate destruction, this telescope is probably completely destroyed? The sheriff who held this case that year also thought so.

But in fact, not.

The bomb hole left on the main mirror of the 107 -inch telescope and the pit that was smashed by the hammer was taken when the main mirror was removed and re -coated.

Although there were 7 bomb holes on the main mirror, and there was a large pit that was smashed by the hammer, the telescope continued to be observed on the second night, and took the best photos of the best photos it had taken at that time.

The impact of these destruction on the telescope is limited to a decrease of 1%of the lighting capacity, which is equivalent to dropped from 107 inches to 106 inches, and introduced a small amount of diffraction.

According to the report issued by the McDonald Astronomy on February 10, 1970, all types of astronomical observations will not be affected by this tragedy.

The telescope was later renamed Harlan Smith telescope and is still in use. It tells us with "personal experience" that large astronomical telescope is not so fragile.

Back to the Webb Space Telescope. Although one of the main mirrors is deformed by the impact of the micro -stars, it has a weak impact on the imaging that can be detected, but for an open -designed space telescope, these impacts are originally unavoidable. At the beginning of the design, it was at the beginning of the design. It has been considered and prepared for the corresponding plan.

According to a blog post released by the Wob team on June 8th, they fine -tuned the affected main lenses and successfully offset a distortion of imaging. At present, the imaging quality of Webb still far exceeds expectations, and is fully capable of completing the scientific tasks designed for it.

All in all, the micro -stars are hit, but the Weibu telescope is still far from "hanging".

The "raw picture" of Webbu "raw picture"

The "Glorious Injury" Weibu Telescope has now begun its busy scientific observation tasks. Thanks to the public and transparent of some projects, some of Webu's observations of the original data will be disclosed and downloaded immediately.

After the wonderful hands of the astronomical image master, we were able to take a glimpse of the officially released pictures, a glimpse of the more wonderful cosmic beauty in the eyes of the Wubu telescope.
