It is known that the James Webb Space Telescope, which was not released for large-scale observation, recently collided with a small micrometeorite.

A micrometeorite is a rocky mass smaller than a grain of sand about 1 mm in size, orbiting the solar system. A collision with small meteors scattered throughout the solar system was expected, but this collision was analyzed to be above the expected range.

On the ninth day, the meteor collided with C3, one of the 18 mirrors that make up the primary mirror of the James Webb Space Telescope from the 23rd to 25th of last month, according to the National Aeronautics and Space Administration (NASA) and foreign media. . The James Webb Space Telescope has encountered a micrometeorite five times since its launch last December, and this telescope was the largest.

The task force announced that the impact of the collision was mitigated by adjusting the C3’s mirrors to compensate for the dent from the crash.

The James Webb Space Telescope is located at the second Lagrange point (L2), where the gravitational pull of the Earth and Sun is balanced. Because L2 is about 1.6 million kilometers from Earth, it cannot be captured by a space shuttle like the Hubble Space Telescope. L2 is also an environment in which dust-sized particles travel at very high speeds. The James Webb Space Telescope was built with this in mind, but it surprised scientists when it encountered a larger-than-expected microtoroid.






NASA said it is conducting an analysis with a panel of experts to find ways to reduce the impact of micrometeor impacts in the future.

“Even after the successful launch, deployment and alignment of the mirrors, James Webb’s initial performance continues to exceed expectations and is designed to perform flawlessly,” NASA said. He added that the launch is still going smoothly.

The James Webb Space Telescope is the largest and most powerful space telescope in human history. In addition to NASA, countries around the world, including the European Space Agency (ESA) and the Canadian Space Agency (CSA), have collaborated on this next-generation telescope, whose main task is to observe the events that took place in the early days. . Universe.

We are excited to see the surviving planets that the James Webb Space Telescope will find in the future.

Vacation: Upgrade Your 4G & 5G Router Speed ​​Now!

Vacation: Upgrade Your 4G & 5G Router Speed ​​Now!

This is a recurring issue. We are going on vacation, but we also don’t want to leave series and films at home. So, we are loaded with a beautiful box or a computer and a mobile router. The problem is that when we get to the place of our dreams, everything turns into a nightmare. This is because in the end we realize that we can not get anything because of the poor speed of the Internet. So, we are going to explain to you a very useful tip to improve the speed of your 4G and 5G router.

Vacation: Improve Your 4G & 5G Router Speed ​​Now!

We all know that antennas, or rather transmitting stations serving seaside resorts, are overloaded in summer. It’s actually a real mess. However, sometimes we have several antennas near us, and simply changing the router can work wonders. Especially if we manage to connect to a freer station.

For example, in the region of Costa da Caparica where we did one of the tests, we have access to two antennas. One is 400 meters and the other 2 km. An antenna that is at a distance of 400 meters is much more overloaded than one that is a little further.

However, when changing location, the router for some reason connects to another antenna that is further away. In fact, the antenna is at a distance of 2.2 km.

One would expect that the further, the lower the speed. Even because if we notice that the signal strength is weaker. However, the exact opposite is happening. This is because this transmitting station is less congested and therefore higher access rates can be achieved.

In fact, the differences can be very significant, and we can go from the chaotic scenario shown in the image below.

For something completely different!

It’s actually something amazing.

It’s just that we might think that the fact that we are farther away will always give us slower speed. However, the reality is quite different.

However, we found just the opposite. More speed!

Thus, it is worth spending a few minutes trying to find the best place to place our router. In my case, I’m using a FritzBox model that shows this data with a link to Antena. However, others do not.

We then have to rely on SpeedTest to check the positions that give the best performance in terms of speed. You can access here do checks.

Xiaomi POCO F4 GT disappoints in its gaming performance tests (video)

Xiaomi POCO F4 GT is one of the cheapest smartphones on the market with a Snapdragon 8 Gen 1 processor. This is the Chinese company’s best offering for the gaming segment, but its performance leaves much to be desired.

This unfortunate scenario was once again confirmed in the latest POCO F4 GT test conducted by the Golden Reviewer Youtube channel. Compared to its peers, this Chinese smartphone could not keep up with the competition.

Xiaomi POCO F4 GT doesn’t want fps in Apex Legends Mobile

The newly released game Apex Legends Mobile was chosen to test the gaming performance of POCO F4 GT. Unfortunately for fans of the brand, the results put him at the end of the table.

On average, Xiaomi POCO F4 GT is presented only 47.5 fps during the gaming session, which you can see in the video above. Clearly poor performance for a smartphone with a strong focus on this market niche.

The performance limitations of the POCO F4 GT start to be noticed already in the third minute of the test. Then we started seeing performance drops for no apparent reason.

From the tenth minute of the test until its end, we see a constant performance in the region of 40 frames per second. Although the POCO F4 GT reached a peak speed of 60fps, it was unable to maintain those numbers throughout the test.

In first place in the table built by the Golden Reviewer channel, we have the Redmi K50 Pro with an average of 59.6 fps. This is an exclusive smartphone for the Chinese market, equipped with a Dimensity 9000 processor.

For European consumers, we have the iPhone 13 Pro Max showing the best performance in this test with an average of 59.1 fps. For Android lovers, the Samsung Galaxy S22 Ultra came out on top with an average of 57.4 fps.

Instagram is testing artificial intelligence to check the age of users

Instagram is testing new ways to verify the age of its users, including an AI face identification tool to make sure people are 18 or older.

There are no tools yet to prevent children from accessing the Meta platform.

The use of artificial intelligence to identify faces, especially in teenagers, has raised some concerns given the Meta’s complicated history. when it comes to protecting user privacy.

Meta stressed that the technology used to check the age of people can’t find out your identity – only your age. After completion of Meta validation in partnership with startup Yoti delete face video.

The owner of Facebook and Instagram said that from today, if anyone tries to change their date of birth on the platform for posting videos and photos of people under or over 18, you will need to verify your age using one of these methods.

Meta continues to face questions about the negative impact its products, especially Instagram, have on some teens.

Technically, children must be at least 13 years old to join Instagram, similar to other social networks. But some solve this problem by lying about their age or by having their parents do it.

To use the face scan feature, the user has to send a “selfie” videosent to Yoti, a London-based startup that uses people’s facial features to estimate their age.

Yoti is one of several biometric companies that are capitalizing on the UK and European push for more reliable age verification technology. to prevent children from accessing pornography, dating apps, and other adult content.

“While Instagram is likely making good on its promise to remove images of candidates’ faces and not attempting to use them for individual facial recognition, the normalization of facial scans raises other social concerns,” a professor at Cambridge University Essex School of Law warned. (United Kingdom) Darag Murray.

In 2021, Meta announced that it was shutting down Facebook’s facial recognition system and removing the fingerprints of more than a billion people after years of scrutiny by courts and regulators.
