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.
The rock samples studied by the team are next to the coin for size comparison.

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.

Being very close companies, OPPO and OnePlus have decided to create a new partnership, with the latter being a pioneer in the market. It has become the representative of the best smartphones in the group, and this will be seen very soon.
Proving this, OnePlus has announced that it will have news soon. The following brand assets will be announced on February 7, 2023. We are talking about OnePlus 11 5G and Buds Pro 2.
In recent years, OnePlus has been showcasing new hardware in an attempt to find a new place in the market. The brand has not always seen its full potential, betting on mid-range or entry-level smartphones.
The situation is changing, and the novelty will go on sale in early 2023, February 7. It is on this day that the new OnePlus 11 5G will be presented with all the expected news. We definitely have the new Qualcomm Snapdragon 8 Gen 2 SoC here. There's still 16GB of storage left and 256GB of onboard storage.
It is expected that he will receive a 6.7-inch OLED display with a resolution of 1440p and a frequency of 120 Hz. In the field of photography, we will have an important change: a 50 MP main camera, a 48 MP ultra wide-angle camera and a 32 MP telephoto lens with 2x zoom. For selfies and video calls, you'll have a 16-megapixel camera.
The photography partnership with Hasselblad will continue with OnePlus for fine-tuning and some additions. This alliance has brought important results for the best smartphones of the brand, guaranteeing the best photos in any situation.
In addition to the new OnePlus 11 5G, another brand new feature is also expected to arrive at the event. We're talking about the Buds Pro 2, which are solidifying an audio commitment that's becoming more of a reality. The brand promises "rich stereo quality sound with crystal clear clarity".
Stays like this marked by the beginning of February, another important novelty will enter the market. OnePlus wants to reclaim its place, and that will be the brand's bet for years to come. OnePlus 11 5G and Buds Pro 2 take the first step in this direction.

According to information provided by Mukul Sharma, the unidentified POCO device can be identified by the model number 22127PC95I. Due to the fact that it was first seen online, the marketing name of this equipment is still a mystery.
POCO has not launched new mobile devices, including smartphones, to the market for some time now. On the other hand, several POCO smartphones such as POKO X5 and X5 Pro have been spotted on various certification sites, suggesting that the company will release these products soon. Today a new smartphone from the sub-brand xiaomi has been spotted on the BIS India website but the device does not have a name or any other details associated with it.

According to information provided by Mukul Sharma, the unidentified POCO device can be identified by the model number 22127PC95I. Due to the fact that it was first seen online, the marketing name of this equipment is still a mystery. It is possible that it will debut as a mid-range smartphone. The Bureau of Indian Standards (BIS) website, other than the model number of the smartphone, does not provide any additional information about the device. However, this seems to indicate that the product will be available in the Indian market very soon.
In other related news, POCO X5 5G has recently been seen on several certification sites including SIRIM in Malaysia, BIS in India and the US FCC. According to various sources, it is possible that this is a renamed or modified version Redmi Note 12 5Gwhich was recently released in China.
It is supposed to be equipped screen 6.67″ AMOLED display with 120Hz refresh rate and chipset Snapdragon 4 Gen 1 inside. Can run MIUI 13 based on android 12 and have LPDDR4x RAM in addition to UFS 2.2 storage. The front camera is rumored to be 8MP while the main rear camera will be 48MP with 2MP depth. May have the ability drums 5000 mAh and 33W fast charging support.
In addition POCO X5 Pro 5G has recently been seen on various sites dedicated to certification. The battery is said to have a capacity of 5000 mAh and can charge at 67W. It will come with MIUI 14 preinstalled and will support n5, n7, n38, n41, n77 and n78 network bands. 5G.
