The study of James Webb’s cosmic telescope determines the age of some of the well -known ancient galaxies, which has appeared much older and further in space than previously thought.
Webb, the United NASA and its European and Canadian counterparts, brought a new look at a piece of heaven, which was made more than 20 years ago by Hablo Space Telescope. At that time, the long -term picture of Hablo was extremely ambitious: scientists directed the telescope seemingly without a stars, without knowing what photons they were collecting.
After all, that particularly deep outdoor image was “set as none other than empty,” said Webbo researchers with thousands of distant galaxies. “
Now, with Webb, this sky patch reveals more about the universe – even by chewing the cosmic time zone. Known as a Miri Deep Imaging study, the project included the mid -infrared instrument of the Webb Telescope, which detects a light wave length invisible to the naked eye. New survey findings published in the magazine Astronomy and astrophysics;
Using Webb, astronomers can observe a weak infrared shine from ancient stars and their designs. According to research, the telescope taught the Habble Ultra deep field area for 100 hours, including 41 hours with one particular filter. The resulting image from the Galaxies collected weak signals when the universe was just a few hundred million years old – the simplest beating.
To understand the deep view of the outdoor space, think about it the way you use the main sample taken from the ground, collecting older rock and soil as you go down: the image is a small but lifted slice of space that reveals a space story, cutting billions of light years, each deeper layer reveals the previous time.
“To our knowledge, this is the longest exposure to one filter, which has been derived from the extragalate area (Webb) so far,” the authors wrote.
The project, briefly named Midis, found nearly 2500 light sources, most of their distant galaxies. About 1000 now has revised distance estimates, depending on how their light has changed.
Webb was built to observe an early period known as the Cosmic Dawn, 100 million to 1 billion years after the Great Bang, detecting light in invisible infrared waves. In short, the light is stretched or “red” over time and distance. Those infrared waves can also break through the prevailing gas and dust in space, otherwise eclipse far and naturally weaker light sources.
James Webb Space Telescope used its mid -infrared instrument to look at the region captured in the famous Hablo Ultra Deep Field image.
In one case, the project states that the galaxies believed to have been 11.8 billion years, closer to 13.3 billion – pushing its origin back to when the universe was only 450 million years old. This gives the galaxy directly into the first wave of galaxies formed.
Other objects of the MIDIS image reveal a different story: hundreds of red galaxies from which some colors have acquired color because they are dusty or have mature, cooler stars. In any case, the results show that the Webb Miri instrument can be a powerful tool to reveal the missed or misconstrued ancient galaxy. Even NASA’s Spitzer, now outgoing infrared space telescope, has seen such a level of clarity.
This is good for researchers looking at how the universe has evolved from the first galaxies to the time of time, when the stars and the supermassive formation of black holes seemed to be the greatest.
“MIDIS is outweighed by confrontation expectations,” the authors wrote. Deep Miri’s portrayal has a great potential to describe the galaxy population from space noon to dawn. “
