Em 2021, the world became known to the super-earth and some data remains open that it could be a very interesting exoplanet. The planet, named Gliese 486 b, orbits the red dwarf Gliese 486, 26 light-years from Earth. An international scientific team led by the Center for Astrobiology (CSIC-INTA) has measured the mass and radius of an Earth-like exoplanet with unprecedented precision.

The interest and work developed in this new world, found “close to us”, made it possible to predict what the structure and composition of its interior, as well as its atmosphere, might be. The data is very interesting.

Is this exoplanet a place where humans could live?

The planet was greeted with great impatience. Thus, the researchers used data from several ground-based and space-based telescopes such as CHARA, CHEOPS, Hubble, MAROON-X, TESS and CARMENES to model the interior of the Gliese 486 b exoplanet.

Thus, a group of astronomers led by José A. Caballero managed to estimate the relative sizes of its metallic core and rocky mantle. Details published in the magazine Astronomy and astrophysics.

The team also made predictions about the composition of the planet's atmosphere, discovered in 2021, as well as its detectability by the James Webb Space Telescope, which will soon point its mirror at the planetary system to which it belongs.

Gliese 486 b has become the Rosetta Stone of exoplanetology. In the solar system we have the terrestrial planets Mercury, Venus, Earth and Mars, and it is now the fifth most studied terrestrial planet in the universe.

Disse José A. Caballero (CAB).

Although it is one of the closest known transit planets, constantly moving at 10% the speed of light, the probe will take 260 years to reach it.

Gliese 486 will be the exoplanet science of the future

In the presentation of this work, the researcher already pointed to additional studies, such as the formation of planetary magnetic fields in the outer core with liquid metals, since Gliese 486 b seems to have the same field as our Earth. These magnetic fields can act as a shield against stellar storms and prevent atmospheric erosion.

Several questions remain unanswered, according to the team: could such an atmosphere be primitive and composed of hydrogen and helium, or composed of carbon dioxide and water vapor from volcanic eruptions, and could Gliese 486 b have tectonic activity?

Although this exoplanet seems too hot for life, its precise characterization could make it the first exoplanet - and so far the only one - where these pertinent questions can be asked. Just a few years ago, trying to find answers was considered science fiction.

First exoplanet around a star similar to our sun 51 pegasus bwas opened in 1995. Since then, every year the astronomical community has found exoplanets that are becoming less massive, closer and more Earth-like.

Although most of them are uninhabitable, transit planets such as Gliese 486 b are of greatest interest to the astronomical community because they allow exploration of their atmospheres and, only for planetary systems closest to the Sun, their interiors.

Project CARMEN ISwhose consortium consists of eleven research institutes from Spain and Germany, discovered three of the eight nearest systems thanks to such transit planets, the last of which was announced last week.

Android 13 Google apps problemas

Android 13 is already a reality and Google smartphone users can install this version. This is still a short list, but it opens the door for other manufacturers to use.

Now that it is available, reports are starting to appear that are not positive. Everything points to problems using various applications, including banking.


Are much news which Google has invested in Android 13, in particular, to protect users and their data. They have been introduced in various test versions released and have finally reached maturity in the latest submitted version.

This new system, still limited to Google Pixels, is gradually moving to smartphones. It's still a small audience, but it lets us know how it will behave in the future. Unfortunately, the news in this area is not the best.

Many reports point to problems using various applications on this new Google system. They seem to have compatibility issues and don't work properly for android system users.

Problems with Google apps for Android 13as

The solution that seems to exist is just waiting for new versions of those apps to come out. Developers should check the issues and release updates to Android 13 versions of their apps with issues within a few days to resolve the issue.

If in previous years one of the solutions could be to return to the previous version of the Google system, then this is no longer possible. One of the measures taken just prevents the regression of the version by blocking the smartphone in the latest version.

This is bad news for Android 13 and for Google, although it's only for developers. All applications should be updated in the coming days, which will allow you to receive support for the new version and fix the problems found once and for all.

For world cat dayAugust 8, g. Pokemon Go released a 3D billboard featuring some of the game franchise’s most beloved feline characters.

On Sept. 5 in Tokyo, at the east exit of Shinjuku Station, an immersive video captures the Cross Shinjuku Vision digital billboard, which made headlines last year thanks to a massive 3D video of a tabby cat.

The one-minute video can only be described as an amazing choreography of hyper-realistic 3D effects. It starts with the good old Pikachu appearing next to the Pokémon Go logo.

A few seconds later, the entire frame collapses to make way for a lush rainforest that is quickly and chaotically filled with various cat figurines entering and exiting the billboard as if interacting with the building itself or speaking to the audience below to greet them. them. The same tropical setting is occasionally flooded with fire, ice or water flowing out of the frame.

At one point, an avalanche of Poké Balls falls off the screen before being “pushed” over the edge by Pokémon – the latter apparently grabbing the frame and looking down with a welcoming smile.
