Scientists may have discovered the first planet outside our galaxy

Published

The Chandra X-ray Observatory may have discovered the first exoplanet outside our galaxy.

At the moment, the found object is a candidate for exoplanets, that is, in the future, scientists would have to try to confirm its essence with the help of other space instruments. However, everything is not so simple here, but more on that below.

The object was discovered in the binary star system M51-ULS-1 in the galaxy Messier 51 (M51), located about 28 million light years from us. By the way, this was the first of the discovered galaxies, for which the spiral structure was confirmed.

At the moment, all the exoplanets we have discovered are inside our galaxy. Moreover, most of them are located at a distance of less than 3000 light years from us. This makes the discovery even more significant.

The potential exoplanet was discovered by the transit method. This is the most effective method at the moment, based on the change in the luminosity of a star when an exoplanet passes in front of it. In this case, the only nuance is that the change in the star’s luminosity in the X-ray range was monitored.

This method has an advantage. The bottom line is that the area emitting X-rays is very small, so a planet passing in front of the star can block most of the radiation or even completely block it out. This makes it possible to detect such signals at huge distances, which is extremely difficult to do in the case of observations in the visible range.

This case is also interesting because one of the components of the binary system M51-ULS-1 is a neutron star or a black hole. And a planet orbiting such an exotic pair is interesting in itself. NASA notes that if it is an exoplanet, it probably had a very turbulent past. She at least had to survive a supernova explosion, which resulted in the formation of a neutron star or black hole in M51-ULS-1. Moreover, in the future this planet can expect another similar event, since the second component of the star system – a massive star 20 times heavier than the Sun – can also explode.

Among other things, scientists were able to determine the approximate size of the object – it is close to Saturn. The distance of an object from its parent star or black hole is estimated at about 20 astronomical units.

However, there is a big problem in this situation. The distance of a potential exoplanet from a star is so great that a year on the planet is about 70 years. And this means that it is simply impossible to confirm the presence of the planet in the system earlier than in these same 70 years using at least a transit method.

Apple, Samsung and Xiaomi smartphones cannot do that. There was a video with the disassembly process of the modular Fairphone 4 and strength tests

Published

The modular and most maintainable smartphone Fairphone 4 fell into the hands of blogger JerryRigEverything.

In this case, we are interested not only in his strength tests, although there is usually only one useful of them, but also in the video of the disassembly process.

As you can see, the smartphone is disassembled and assembled as easily as possible, and even the display is dismantled simply by unscrewing a few bolts. There is no need to talk about the simplicity of the battery replacement process. No other device in this segment offers this.

At the same time, modularity did not affect the strength in any way. Thanks to the metal frame, the smartphone practically does not bend, which is very good. The plastic of the back cover does not suffer from this effect either.

Recall that Fairphone 4 is based on SoC Snapdragon 750G and is equipped with an IPS screen, 48-megapixel main camera and a 3905 mAh battery.

Google makes life easier for Android TV owners by adding the ability to install apps from a smartphone

Published

Google has made life easier for Android TV owners. These users can now install applications on their TVs directly from their smartphones.

To install, just go to Google Play from your smartphone and select a TV from the drop-down list as the target for installing the software. Similarly, Google has implemented the installation of applications on smartwatches with Wear OS.

This approach allows, firstly, to install the application faster and easier, since it is still easier to do all the manipulations from a smartphone, and secondly, in this way, you can install the application remotely without being in front of the TV.

Computer in “credit card” format. Qualcomm develops Qompute Card concept despite Intel’s failure

Published

on

Qualcomm is reportedly developing a concept called the Qompute Card.

It involves placing all the basic elements of a PC on one small board. This will allow you to easily and quickly update the configuration of such a PC or use such cards by one user in different places on different PCs. Also, a similar solution can find application in household appliances.

The concept is not new at all. Back in 2017, a similar idea for the Intel Compute Card was presented, but the company abandoned it two years later, since it did not receive any distribution in the market.

Qualcomm as a whole makes a very similar decision, except that the heart of such cards will be SoCs based on the Arm architecture. The Qompute Card will also contain the motherboard, RAM and flash memory. That is, all the main elements of the finished device. At the same time, Qualcomm cards may well be significantly smaller than Intel Compute Card, if only because of the different power consumption of SoC Snapdragon and conventional Intel CPUs.

Qompute Card are aimed specifically at computers and laptops. At least the SoC Snapdragon 7c + Gen 3 presented the other day will also be offered as part of the cards. The source adds that Qualcomm is testing configurations for both Windows Arm and Chrome OS. How successful this version will turn out to be, time will tell. So far, all such modularity initiatives have not met with success.
