NASA Celebrates the Opening of the James Webb Primary Mirror: Telescope Now Working

The James Webb Space Telescope opened its last and most important mirror this Saturday and is fully operational this weekend after reaching its final configuration over 20 years in preparation.

Two weeks after leaving planet Earth, the last “space envoy” of mankind beyond the last border of the Earth deployed, opened and installed a gilded mirror with a diameter of 6.5 meters, which he carried when folded to save space and pick up speed.

Now the telescope is ready for full-fledged work, which, however, should begin only in June, when it reaches a certain orbital position 1.5 billion kilometers from Earth.

James Webb will still have to go through a planned third incineration in order to align a route to an orbit defined around a second Lagrange point, nicknamed “L2” in the astronomical environment.

Bill Nelson, one of the administrators US space agency (NASA) predicts “about six months” until “images” collected by James Webb begin to arrive on Earth.

After this first leg of the journey, there will be five months of cooling, routing and calibration before the telescope starts sending data back to astronomers from NASA and the Canadian Space Agency, which is also involved in the project.

“When this starts, the horizon will no longer be our limit, and we will collect all kinds of new knowledge about who we are, what we are, where we came from and if there is still life in space,” said a NASA spokesman.

The James Webb Telescope predicted that it would record more than 13 billion years of activity in space with unprecedented accuracy, beyond the last boundary of planet Earth.

This new “space envoy” NASA is also tasked with discovering new galaxies, studying the atmospheres of planets far, far away, and assessing whether they are suitable for human life.

The James Webb Space Telescope is an unprecedented mission to see the light of the first galaxies and uncover the secrets of our universe. Every feat already achieved and every future achievement is a testament to the thousands of innovators who have put their passion into living this mission, ”said Bill Nelson.

A black hole has swallowed a star and is spewing a jet at us

A black hole has swallowed a star and is spewing a jet at us

One Black hole it swallowed a star and fired relativistic jets at some corner of the universe far from our galaxy — enough to be the most distant black hole food astronomers have ever observed. The discovery became possible only because the jets were directed in our direction.

When a star gets too close to a black hole, a powerful gravitational force begins to tear it apart. stretching your matter like spaghetti🇧🇷 This is a one-way process. Although it has not yet passed through the event horizon (a point from which not even light can escape), the star is broken.

This event, dubbed AT2022cmc, was discovered in February this year by ZTF, an autonomous system that tracks and extracts information about unusual phenomena in the universe in visible light. Therefore, scientists sent several telescopes around the world to observe the source of radiation at other wavelengths.

Many wavelengths have been detected in the radiation released from this event, from gamma rays to radio waves, in addition to visible light itself. This was possible because the plane was directed in our direction (although without any threat), which is very rare.

The advantage of having the jet pointing towards the Earth is that in this way its brightness becomes much more intense, which allows it to be observed at different wavelengths and better calculate the distance to it. This led the team to calculate that the black hole was feeding when the universe was only a third of its current age, about 4 billion years old.

To get this result, the team needed to collect data from 21 different telescopes and compare the information to theoretical models of several types of known extreme events, such as stellar collapses and kilonova explosions.

The only scenario that explained the findings was a phenomenon called “tidal disruption,” where a black hole devours a star, stretching it like chewing gum. Other events from tidal disturbances have been observed beforebut this happened much closer to us and without jets directed in our direction.

Astronomers are constantly looking for these extreme events to better understand how these jets form, how they get so much energy, and why so little tidal disruption forms them. This is the first time an event of this type has been detected using visible light, so astronomers should invest even more in instruments like the ZTF.

This study was published in the journal Nature.

Google Chromecast atualizações software

Since the introduction of the Chromecast in 2013, it has proven its worth. It is capable of turning any TV into an internet-connected smart device with access to the content the user wants to present.

Chromecast and Google TV (4K) build number: STTE.220621.019.A2
  • security update: Android security patch level updated July 2022
  • Update Android TV from version 10 to 12
    • Additional custom settings allow you to control the HDR format and surround sound.
    • New: Content Frame Rate Matching option allows you to switch between refresh rates.
  • More security and privacy
    • New camera and microphone privacy buttons let you disable or enable camera and microphone access for all apps.
  • Additional bug fixes and performance improvements

To manually download the latest update, follow the instructions provided here.

Google extends to all models

This list of updates from Google also has a few gems like Chromecast Audio that aim to bring the concept to the audio part. The Chromecast Ultra also now sees its updated version and gets the same bug fixes and other improvements.

To check your device version, Google recommends that you open the Google Home Google Home app, press and hold the device tile. Then click "Settings" and then "Device Information". In the "Technical Information" section, find the Cast firmware: "X.XXX.XXXXX".

Google Chromecast software updates

How to access new software

Updating devices is extremely simple. It usually downloads updates automatically. To manually download the latest update, follow these steps:

  • Accessing the Chromecast Home Screen with Google TV
  • Select Settings, then System, then About, then System Update.

It's great to see that Google is updating the Chromecast all the way back to the first version of the device. It won't bring much news, but it will certainly improve this offer and make it more stable and hassle-free for users.

Imagem de: CD Projekt Red quer mais lançamentos como Cyberpunk Edgerunners

after one extremely difficult startCD Projekt Red looks ok now satisfied with the results Cyberpunk 2077, especially after the release of the anime based on the series, released by Netflix. So much so that the producer intends to repeat the feat with more transmedia releases in future. Information taken from Video Games Chronicle.

This intention of the Polish company was disclosed this Monday (28) during the last meeting regarding its financial report. During the conversation it was commented how the success of Netflix animation helped boost game sales.

Launched in September Cyberpunk Edgerunners (Cyberpunk: The Expendables in Brazil) is considered the story intertwines with the game Cyberpunk 2077, which was a huge success for both the streaming platform and the Polish developer. Furthermore, animated series revived public interest in the gamewhich no longer suffered from the myriad problems revealed in its release.

Throughout the meeting, CD Projekt Red management was asked about the possibility of a second season of the popular anime🇧🇷 “We are not confirming any concrete plans for the second season of the series. Edgerunners and nothing special,” explained Michal Nowakowski, senior vice president of business development at the production company, before moving on to the interesting part of the comment.

We want to do more in the transmedia spacewhether it’s linear visual animation or live actors, and those plans haven’t changed,” Nowakowski added. “When we’re ready, you expect to see more announcements from us in this regard“, he concluded.

Taking into account not only Edgerunnerswhich revived interest in Cyberpunk 2077 e led the company to record revenue for the periodbut also games and cartoons Witcher (also on Netflix), it’s to be expected that CD Projekt Red really intends to continue with this strategy.
