NASA What is this? NASA, European Space Agency, and Canadian Space Agency. Image processing: Joseph DePasquale (STScI) The James Webb Space Telescope was doing its usual business — looking at objects of scientific interest across the universe — when it accidentally picked up something funny and familiar in the distant universe. Is it a giant question mark? ??? NASA, European Space Agency, and Canadian Space Agency. Image processing: Joseph DePasquale (STScI) It sure looks like one. Is the universe trying to tell us something? Or ask us something? Or is he just making fun of us? In fact, scientists think it might be a merged pair of galaxies. They happen to form a question mark, as seen from a web’s perspective. “Their interactions may have deformed the shape of the question mark,” said representatives from the Space Telecope Science Institute. Space.org says. What are you playing, James Webb Space Telescope? NASA GSFC/CIL/Adriana Manrique Gutierrez; “This may be the first time we’ve seen this particular thing,” STScI said. “Further follow-up will be required to determine what is confirmed.” It may also be a single oddly shaped galaxy, but the merger sounds like a good explanation for Matt Kaplan, associate professor of physics at Illinois State University. After all, galaxies collide and merge all the time. A pair of merging galaxies has been captured by Webb. “The two separate features might easily merge background galaxies, with the top of the question mark part of a larger tidal disturbed galaxy,” Kaplan told Space.com. “Looking at the color of some of the other background galaxies, this doesn’t seem like the worst explanation. Despite the chaotic nature of the fusions, the double-lobed bodies with the curved tail that recede from them are very typical.” The bigger picture Webb wasn’t looking for a question mark. Here is the largest image captured by the telescope: The full image shows what Webb was looking at first: a pair of stars in an active formation, called Herbig-Haro 46/47. NASA, European Space Agency, and Canadian Space Agency. Image processing: Joseph DePasquale (STScI) Nice, isn’t it? NASA released this image on July 26, saying in a affidavit that it shows the “actions” of two young stars who are still actively training. “Look for it in the midst of red diffraction spikes,” NASA wrote in the statement. “The stars are buried deep, appearing as an orange-white spot.” The pair of stars, known as Herbig-Haro 46/47, grow by feeding on the gas and dust surrounding them in a disk. The disk itself is not visible, but its shadow appears in two dark, cone-shaped regions next to the stars. The pinkish-orange lobes that dominate the image are material that stars shed as they grew for thousands of years. NASA added that the pair of stars is “an important object to study because it is relatively young – only a few thousand years old.” Star systems take millions of years to fully form. Targets like these give researchers insight into the amount of time mass stars have, allowing them to model the formation of our sun, which is a low-mass star.

The weather is stormy for Disney. Bob Iger, who returned to the helm of the American entertainment giant nine months ago, faces many challenges. Revenues from conventional television are down, streaming continues to post quarterly losses and the strike by actors and screenwriters should weigh on results in the coming months.

The American giant has just published gloomy results. Its revenues increased by 4% over one year, thanks to the influx of visitors to its amusement parks and cruise ships. But the profits associated with its media and entertainment division fell by 18% in one year. Over the last nine months, they even collapsed by… 46% compared to last year.

When buying a graphics card, if there are multiple VRAM options for the same model, many people may encounter a choice barrier. They don’t know which one to choose, or the standard version. Recently, some YouTubers use the latest RTX 4060 Ti 8GB and 16GB To explain this, and show why you shouldn’t choose 8GB in 2023, most games will perform much better with 16GB, and in the long run, it is indeed better to choose larger VRAM. Foreign YouTuber uses actual measurements to explain why you should not choose 8GB VRAM when buying a graphics card in 2023 A few days ago, foreign YouTube channel Daniel Owen shared a video “How bad is 8GB VRAM in 2023”, he used RTX 4060 Ti 8GB and RTX 4060 Ti 16GB for two graphics cards, to illustrate how much more VRAM affects modern games. Owen found that many games will use more than 8GB of VRAM when running by 2023. He tested seven of the latest 3A game masterpieces, including “Ricky and Clank: Rift Apart”, “Star Wars Jedi: Survivor”, “Spelled Land” “, “Cyberpunk 2077”, “Evil Castle 4”, “Remains 2” and “The Last of Us Part 1”, each game also runs a variety of quality settings, such as 1080p, 1440, 4K, open RT and so on. The actual measurement shows that most games require more than 8GB of VRAM, most of which are between 9GB and 111GB. If “Evil Castle 4” is set to 4K resolution and the highest image quality, it requires 12.1GB, which means that the RTX 4060 Ti 8GB is completely Not enough, 16GB can handle it: But even so, not every game’s 16GB game performance is much better than 8GB, here I pick up a few more important games. In the game “Evil Castle 4”, the RTX 4060 Ti 16GB is 11% faster than 8GB at 1080p, 9% faster at 1440p, and 24% faster at 4K. What is more noteworthy is that 1% lows, the bottleneck of 8GB becomes more obvious, 16GB has a performance lead of 77% ~ 113% among the three resolutions: “Ricky and Clank: Rift Apart” also has a big gap, enable RT And in the 1080p Very High setting, 16GB is 34% faster than 8GB, 1440p widens the gap to 43%, and 4K reaches 85%, but the gap is not so big when RT is turned off: “Relics 2” and “Star Wars Jedi: Survivors” “There is no obvious performance improvement, 16GB and 8GB are similar: “Cyberpunk 2077” is also, Owen also found that following using DLSS 3 technology, it will consume more VRAM, such as RTX 4060 Ti 16GB 1440p RT Ultra configuration, consumes 8426MB VRAM , following changing to DLSS image quality, the VRAM becomes 7249MB, 1GB less. The same is true for RTX 4060 Ti 8GB, but because of the bottleneck, the consumption level is not as high as 16GB: So, the 16GB version with a slightly more expensive price will basically have better game performance than 8GB, although not every model is like this, but at least It can be determined that in the long run, it is a better investment, and the demand for VRAM in games will only increase in the future. But if most of you are not playing 3A games, I think that if the price difference is too big, the 8GB version can actually be considered, following all, it is true to save money. Full video:

Earendel. For connoisseurs of the work of JRR Tolkien, this name evokes a character from Silmarillion who has a jewel as bright as a star. It is also the name given to WHL0137-LS, the most distant individual star ever observed to date. We owe its discovery to the Hubble telescope in March 2022. Now, the James Webb space telescope has taken over and, thanks to its formidable infrared observation capabilities, provides more precise information on Earendel.

This star shone in the earliest times of the universe, regarding 900 million years following the Big Bang. It took 12.9 billion years for the light from Earendel to reach us. If we take into account the expansion of the universe, the star is 28 billion light-years from our planet.

Hubble was able to spot Earendel thanks to the phenomenon of gravitational lensing, in which the gravity of a massive object in the foreground acts like a lens by warping the fabric of space and time, bending and brightening the light coming from a more distant body when this light passes nearby.

Earendel is a million times brighter than the Sun.

James Webb also exploited this phenomenon to observe Earendel last summer. Thanks to its data, we now know that it is a B-type star. more than twice as hot as our sun and regarding a million times brighter “says NASA. Another key piece of information, the colors of Earendel suggests that it is accompanied by another star ” colder and redder ».

On the strength of these discoveries made possible by James Webb, astronomers are cultivating the hope of one day being able to detect the first generations of stars, those which gave birth to the universe during the Big Bang and with which everything began.
