What will be the Webb Telescope’s first target?

Published

Right now, the Webb Space Telescope is beginning to align the 18 segments of its primary mirror. As NASA indicated, this is quite a lengthy process that will take several months. The 18 hexagonal segments must indeed be perfectly aligned to form a single united surface similar to a single giant mirror. But when the telescope is ready, which part of the sky will it observe first?

According to the explanations of Jane Rigby, scientist working for the Webb project, the very first images captured by the telescope will be part of the process of aligning the elements of the primary mirror. Rigby thus indicates that one should not expect too many first quality images.

During an online press conference on Saturday, January 8, Rigby explained to reporters that the first images were going to be “ugly” and “blurry”.

Precision is key

During the press conference, which was given to celebrate the successful deployment of the primary mirror, members of Webb’s team did not indicate whether they would still release these first images that were expected to be “ugly”. “. They explained, however, that the segments of the primary mirror will initially be shifted by several millimeters, which represents a very large degree of inaccuracy when it comes to observing distant cosmic objects.

Engineers hope, however, that 120 days after launch, around April 24, the telescope will be able to start seeing more clearly. The alignment process will indeed be completed.

The first “real” sighting

But what about the first “real” sighting? According to the information, NASA received many requests from astronomers in relation to the targets that could be studied, but the vast majority of these requests had to be refused.

On the NASA site, one can see a list of some preliminary scientific programs, but there is no indication of the very first cosmic object to be studied.

However, we do know some of the targets that will be used during the alignment process. According to Rigby, there are a few sources that exhibit uniform brightness to verify that the detectors are working. She added that many of these sources are in the Large Magell’s Cloud since you can see the north and south ecliptic poles all the time.

The Large Magellanic Cloud is a dwarf galaxy close to the Milky Way. Rigby explains that the sources located in this galaxy always remain visible, regardless of the date of liftoff. And we can say that it is a good decision if we consider the multiple postponements of the launch of Webb.

Engineers came up with a way to increase the cooling

US engineers have come up with a new way to cool semiconductor products, which does not involve the use of a thermal interface. Conformal coating in laboratory conditions has demonstrated its high efficiency in comparison with traditional methods of heat removal.

Engineers came up with a way to increase the cooling efficiency of processors by 700%

Electronic devices heat up during operation, and the greater the power, the stronger the heating, all other things being equal. This problem is especially acute with the miniaturization of devices. Researchers at the University of Illinois at Urbana-Champaign have come up with a new efficient way to remove heat from semiconductor products.

Usually, a radiator is connected to the hottest places of the microcircuit through a thermal interface. For example, thermal paste. Instead, American scientists proposed to cover the entire device with a thin layer of polymer insulator, and “fill” it with a layer of copper on top, completely repeating the shape of the device. This conformal coating is in close contact with the device and effectively removes heat from it.

“We compared our coatings to standard heat dissipation methods. It turned out that our method dissipates 740% more power per unit volume.one of the researchers explained.

It is expected that in the future this invention will make electronic devices, including telephones and computers, more powerful and compact.

US military space intelligence to spend billions of dollars buying

The US National Space Reconnaissance Office announced the largest ever contracts worth “billions of dollars” for the purchase of satellite imagery from commercial companies. There are three such companies – BlackSky, Maxar and Planet.

“These contracts, which are valued in the billions of dollars and will run for the next 10 years, represent a historic expansion of commercial imagery purchases by the National Space Intelligence Agency.”the agency said in a statement.

The exact amount of contracts is not called. It is noted that they are concluded for five years with the possibility of an additional extension until 2032.

Huge cheap smartphone with a giant battery Tecno Pova 3

Tecno introduced the Pova 3 smartphone, which boasts a huge battery and a huge screen.

The novelty received a 6.9-inch 90-Hz IPS display with Full HD + resolution. The battery capacity is 7000 mAh. Samsung has stopped experimenting with such smartphones, so it is very, very difficult to find something like this on the market.

The heart of the novelty is the SoC MediaTek Helio G88. There are 4 or 6 GB of RAM and 64 or 128 GB of flash memory. The main camera is represented primarily by a 50-megapixel main sensor, and the other two can be left out, as these are just “plugs” with a resolution of 2 megapixels. The resolution of the front camera is 8 megapixels.

From the rest, we can note stereo speakers, a design diluted with a vertical stripe, 25-watt charging and 10-watt reverse charging. By the way, for some reason, a 33-watt charger comes with the device, so this value appears in some promotional materials, which is confusing.

In the Philippines, where the smartphone first debuted, it costs just $172.

Netflix hid nine NFTs in its Love Death Robots

The third season of Love, Death & Robots premiered on Netflix last Friday. The service prepared a surprise and placed QR codes in different places and episodes that allow you to “mint” NFTs.

Netflix hid nine NFTs in its Love, Death + Robots series

Minting, also often referred to as minting, is the process of creating a non-fungible token and “registering” it on the blockchain. Usually, in order to “mint” NFT, you need to pay a network fee. After that, information about the non-fungible token and its author will be included in the blockchain.

The most popular NFT minting network is Ethereum. In February 2022, the amount of non-fungible ETH tokens used for minting reached a maximum.

The action is calledHunting 101“. The point is that the organizers hid 9 different NFTs in the form of QR codes. And the task of the viewer is to find them.

NFTs can be found both in the digital world of the series and in the real world: for example, on billboards and billboards.

When the user has found and scanned the QR code, it is necessary to mint the token through a smart contract. Or the second option is to simply download the JPEG image to your device.

According to the show’s official OpenSea account, viewers have only found three NFTs so far.

The number of tokens is not limited. This means that any user can find the same QR code and mint the NFT. The company does not charge for this. But in order to transfer NFT to your Metamask wallet, you need to pay for gas on the Ethereum network.

Further, the user can keep the tokens for himself for the collection, or resell on OpenSea. Now the average price of an NFT from Netflix is ​​0.0031 ETH (about $30).
