extraterrestrial rock

A well-known and controversial stone, possibly of extraterrestrial origin, made headlines.

It is now claimed that the rock of Hypsia, found in Egypt in 1996, could have been the result of a Type Ia supernova explosion.

Since it was discovered, several teams have analyzed the curious rock, but conclusions have varied widely, from claims that it could have originated right here on Earth to speculation that it was either a type of meteorite or even a rock behind it. outside. Solar system.

Jan Kramers and his colleagues at the University of Johannesburg in South Africa conducted a new analysis and arrived at perhaps the most “radical” conclusion reached so far.

“In a sense, we could say we ‘caught’ the Ia supernova explosion ‘in action’ because the gas atoms from the explosion were captured by the surrounding dust cloud, which eventually formed Hippocia’s parent body,” Kramers said. said.

forensic chemistry

The team claims to have performed “forensic chemistry” on several samples, ruling out all “cosmic suspects” in the origin of the rock, which has a curious composition full of microdiamonds and an almost complete absence of silicates.

“Instead of exploring all the incredible anomalies that Hippokia represents, we wanted to find out if there is unity at the core. We wanted to see if there was any consistent chemical structure in the stone,” the researcher said.

To do this, 17 targets were selected in the sample far from terrestrial minerals formed in cracks in the original rock that fell to Earth, possibly millions of years ago.

“We found a consistent pattern of micronutrient abundance that is completely different from anything in the solar system, whether primitive or evolved. Objects in the asteroid belt and meteors do not match this either. So we are looking beyond the solar system,” he said. Kramers said.

A large amount of iron and a small amount of silicon and other elements heavier than iron ruled out the possible origin of the stone from a red giant star, which is very common in the universe.

A Type II supernova also did not fit the explanation due to the large amount of iron and the presence of minerals such as nickel phosphide.

A much rarer Type Ia supernova, one of the largest sources of iron in the universe. And so the team followed.

type Ia supernova

Looking at what you would expect to find in a supernova, eight of the 15 elements analyzed are within the predicted proportion ranges relative to iron: silicon, sulfur, calcium, titanium, vanadium, chromium, manganese, iron, and nickel.

However, not all of the 15 elements analyzed in Hyptius match the predictions. In six of them, proportions were 10 to 100 times higher than the ranges predicted by theoretical models for type 1a supernovae: aluminum, phosphorus, chlorine, potassium, copper, and zinc. But that wasn’t enough for the team to abandon their hypothesis.

“Because a white dwarf formed from a dying red giant, Hippokia could have inherited these ratios of elements to the red giant’s six elements. This phenomenon has been observed in white dwarfs in other studies,” says Kramers.

If this hypothesis is correct, the Hippokias rock will be the first physical evidence of a supernova explosion on Earth, one of the most energetic events in the universe.

But given the history of research on the enigmatic stone, one can predict that with the publication of this new work, new, somewhat explosive opinions will appear, and it is reasonable to wait for new analyzes and new hypotheses.

last year, A game called Crayon Shin Chan: Ura to Hakase no Natsuyasumi (Crayon Shin-chan: My summer vacation with a teacher). A mix of legendary manga Pencil Shin Chan And in the long run my summer holidays A series of video games, it felt slow, laid-back, relaxing and everything you could want from a game with a summer vacation focus.

Here is the trailer for the 2021 Japanese release:

Crayon Shin-chan “Ora and the Doctor Summer Vacation – Seven Day Journey – [Nintendo Direct 2021.2.18]

Looks nice, doesn’t it? Kazu Ayabe, director of the main series, was also in charge of this game, and the addition of more modern visuals – it was the first game for PS1 and the last for PSP – made everything even better. Like every other game in general my summer holidays Series We all assumed that this would be a Japan-only release, but it turned out that we were wrong at best.

An image from an article titled

Earlier today it was announced that it is not only Crayon Shin Chan: Ura to Hakase no Natsuyasumi It’s now out on PlayStation 4, but is also being translated into a number of Western languages, including English, German, Spanish, and Portuguese.

If you are wondering how these games work, then they are all about games during the summer holidays for children. You walk around a sleepy city, talking to people, playing a few games, and generally hanging out. As the game’s new English website says:

Enjoy the feeling of Japan in the height of summer. Walk under the open sky and listen to the sound of cicadas in the mountains and the gentle murmur of streams floating through the greenery. This is an experience that will instantly make you feel nostalgic for a Japanese summer.

international version Crayon Shin Chan: Ura to Hakase no Natsuyasumi It will release in August for PS4 and Nintendo Switch.

Artificial intelligence helps Instagram check your age from your face

Artificial intelligence helps Instagram check your age from your face

How old are you? Well, this question never leaves you, no matter how old you are. You feel happy answering until you reach an age that you don’t really want people to know about, and if you’re underage, social media platforms won’t be replaced by people. But this time, Instagram has prepared something different for everyone. Instagram is testing new age verification methods, including asking followers to verify their age and even using artificial intelligence (AI) to estimate your age through video selfies. It’s part of an effort to ensure users are at least 13 years old and “ensuring that teens and adults have the right experience for their age group,” he announced.

Currently, Instagram only asks users to verify their age when teens attempt to change their date of birth to show they are 18 or older. To verify their age, users can upload photos of various IDs, and starting today, users in the US will have two additional options: social proof and AI scoring.

Users in the US can also upload compatible ID photos to verify their age on Instagram. The company also uses another method called social proof. It involves three people aged 18 and over who are the user’s followers. They need to verify that user’s age if they receive a request from Instagram within three days.

Instagram also checks user posts after they are eligible for additional verification, such as if a person pretending to be 20 posts about celebrating their 16th birthday. It even tests a method based on a person’s written posts to see if they’re posting as a teenager or an adult, although we certainly see many adults on Instagram posting as if they were teenagers.

NASA launches Microwave-sized CubeSat to the Moon as part of Artemis program

The week has been a very busy one for NASA, and after yesterday’s historical launch of a rocket launched into space in Australia observe the constellations Alpha Centauri A and B; Today, a small CubSat was sent to the Moon as part of the Artemis program. A cube the size of a microwave and weighing 25 kg will test the lunar elliptical orbit.as part of the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE).

It will be an explorer or reconnaissance route for the Gateway, a space station that will orbit the moon, as part of the Artemis program, which aims to return a person to a natural satellite. CAPSTONE will help mitigate the risk of future spacecraft by testing innovative navigation technologies as well as testing their orbital dynamics.since it will be the one that the astronauts will use.

NASA CAPSTONE ” data-title=”NASA CAPSTONE – NASA Launches Microwave-sized CubeSat to the Moon as Part of Artemis Program – SAPO Tek”>

This orbit consists of a seven-day journey that the spacecraft takes to circle the Moon, allowing vehicles to get closer to its surface. The goal is to test the path that the Gateway will take on its path.. BUT NASA says that CAPSTONE is currently in lower Earth orbit and has a four-month journey to reach its destination. Your path may be monitored in real timeon a 3D map provided by the space agency.

The small cube mimics the flight of Rocket Lab’s Lunar Photon rocket. Shortly after launch, The Lunar Photon has separated from its second stage, and over the next few days, the engine will periodically turn on to accelerate the vehicle out of lower Earth orbit.. This is followed by the final separation of the CubeSat to follow its trajectory towards the Moon.

The final stage of CAPSTONE’s journey will be provided by its own system of proportions, as well as gravity from the Sun to the Moon. O Using gravity will drastically reduce the fuel consumption of a small device..
