James Webb Space Telescope discovers two oldest galaxies

NASA’s James Webb Space Telescope has discovered two of the oldest galaxies. It is known that one of them was formed 350 million years after the Big Bang, and the other – 450 million years later.

James Webb Space Telescope discovers two oldest galaxies

According to the current ideas of cosmologists, the first galaxies appeared in the Universe approximately 300-400 million years after the Big Bang, when its matter had time to cool down to temperatures at which cold clouds of gas can form, inside which stars arise. Scientists have been looking for and studying the properties of such galaxies for several decades in the hope of revealing their role in the chemical evolution of the universe.

The researchers used images taken by “James Webb” to search for analogues of the galaxy GN-z11, one of the most distant objects in the early universe. Its properties were studied with the help of Hubble and other space and ground-based observatories. To detect ancient galaxies, scientists took advantage of the characteristic features of the spectrum of such objects, which reflect the interaction of the radiation of their young and bright stars with the surrounding accumulations of dust and gas.

As it turned out, in the first images of “James Webb” there are two such objects at once: GLASS-z12 and GLASS-z10. The first of them is 13.4 billion light-years from Earth, and the second is 13.3 billion light-years away, which makes them the same age as GN-z11. In shape and size, both of these galaxies turned out to be very similar to GN-z11 and other ancient star clusters, but at the same time their brightness turned out to be much higher than expected.

Follow-up observations of GLASS-z12 and GLASS-z10 and the study of the obtained spectra of these galaxies, as astronomers hope, will help them uncover the reason for the anomalously high brightness of these objects, as well as understand which stars were present inside them. This information is critical to understanding how the universe became transparent to electromagnetic waves and how it became saturated with heavy elements.

Reliable insider Ice Universe has posted some more comparison photos comparing the 10x zoom capabilities of the Samsung Galaxy S22 Ultra and Vivo X90 Pro+.

“The era of Samsung’s dominance in 10x zoom shots is over,” Ice Universe said commenting on these shots, adding that he has taken hundreds of similar comparison photos that leave no doubt about the advantage of Vivo X90 Pro +.

Recall that the Vivo X90 Pro + received the main image sensor Sony IMX989 optical format 1 inch and Zeiss optics, consisting of eight elements. He also received a periscope module with a 64-megapixel OmniVision OV64B sensor, which provides 100x zoom. In addition, the Vivo X90 Pro + debuted a 50-megapixel Sony IMX758 sensor.

Yesterday, the same insider already published a comparison of these smartphones at night, stating a large gap between them.

Ice Universe was the first to accurately talk about the new trend of smartphones with waterfall screens, the notch in the iPhone X, the new design of the iPhone 14 and Samsung’s 200-megapixel image sensor. Recently, he was the first to accurately report that Redmi Note 12 Pro + will receive a 200-megapixel main camera. Exclusive information about new products is leaked to him by sources in the research and development department of the South Korean giant.

The well-known insider Ice Universe, who regularly shares exclusive information about the latest in the mobile industry, has published a new image of the flagship smartphone Xiaomi 13.

This render confirms that the smartphone will receive a flat screen with a narrow frame around the entire perimeter. On the sides and top, the width of the frame will be 1.61 mm, and at the bottom of the screen it will have a width of 1.81 mm. In this case, the effective display area will be 93.3%.

Xiaomi 13 will receive an elegant flat screen with an ultra-thin frame. I think about it again: in 2023, the whole world is narrowing the frames, and only Samsung is increasing the frames in S23, contrary to the global trend.

Earlier, he also said that Xiaomi 13 and Xiaomi 13 Pro will receive the best screens currently on the Android market manufactured by Samsung. Their screen brightness will be higher than the Samsung Galaxy S22 Ultra.

Mass riots in the city of the iPhone showed on

Well-known insider Ben Geskin, who lives in Latvia, published a video that shows clashes between workers and the security service of the Foxconn plant.

He also reported that the supply of new iPhone 14 smartphones to one of the local Apple stores had completely stopped.

One of my friends just went to our local Apple Store and asked about orders for the iPhone 14. He was told that the supply of smartphones has completely stopped. New orders will take a very long time. The iPhone is good, but I feel most sorry for those people who are locked in the Foxconn factory.

According to Reuters, by the end of November, a further reduction in the supply of iPhone smartphones is expected. Tens of thousands of employees left iPhone City after receiving $1,400 each from Foxconn.

Ben Geskin regularly posts interesting concept art and renders based on rumors and various leaks. He was the first to publish accurate renderings of the iPhone X and iPhone 14, as well as a number of other new products from Apple, Samsung, Xiaomi and other companies.
