Ancient meteorite older than the Earth discovered

Ancient meteorite older than the Earth discovered 88

A space rock formed 4.5 billion years ago during the birth of the Solar System could help us understand the origins of life on Earth.

The tumultuous period during the birth of the Solar System saw space rocks swarming around the growing gravitational field of the Sun and colliding at a rapid rate to form the planets, moons and meteors we see today.

Scientists have analysed one of the meteorites that formed during this period before crashing down on Earth 4.5 billion years later.

The analysis of the ancient grapefruit-sized space rock, known as Orgueil, revealed the elemental building blocks for life.

A chemical ‘fingerprint’ for oxygen, carbon and nitrogen was discovered hidden within the meteorite, opening the door for further research into how life blossomed on Earth and potentially on other planets, both in and outside our Solar system.

A space rock that was created 4.5 billion years ago during the birth of the Solar System could help us understand the origins of life. One of the meteorites created during this fiery, ancient period of time then landed on Earth and has now been analysed by scientists who saw the elemental building blocks for life were present on the football sized rock (pictured)

The rock is made of the first solid materials – such as rocks, organics, water ice, and fine grain dust – that formed in our Solar System.

When these early rocks are discovered on Earth, they act as time capsules to help scientists understand how planets formed and evolved over billions of years.

Isotope analysis of the 4.5 billion year-old Orgueil meteorite revealed traces of carbon, hydrogen, oxygen, nitrogen, and sulphur – all of which are central to the beginnings of life.

Isotopes are varying versions of the same element, with a different amount of protons but the same number of neutrons in the nucleus.

The research, published in PNAS, confirms these organic materials were likely formed via basic chemical reactions during the solar system’s infancy.

The scientists, led by researchers at the University of Manchester, believe that if organic materials can be formed through relatively simple processes, it is possible they are widespread elsewhere, too.

As well as helping us understand more about our own planetary system, it could also help us learn about the habitability of other solar systems.

The asteroid, borrowed from the Muséum National d’Histoire Naturelle in Paris, is an extremely rare rock known as a carbonaceous chondrite and weighed around 30 pounds (14kg) when it landed. It was first discovered in 1894 in southwest France.

Only a few per cent of all meteorites are Chondrites – rocks that have not been changed due to melting during their journey in space – making them hard to come by, and even harder to study.

The research team spent two years measuring and interpreting the oxygen isotope composition of organic compounds in some of these early-formed meteorites.

Polar vortex: “wild” winter is coming in the US, Northern Europe and East Asia after the 16th of January

Polar vortex: "wild" winter is coming in the US, Northern Europe and East Asia after the 16th of January 96

In the upper atmosphere above the North Pole, experts saw a rapidly swirling vortex of cold air that could bring severe frosts to the United States, Northern Europe and East Asia. Serious cold snap and snowy weather are expected after January the 16th.

Snowfalls and a cold snap hit South Korea since the start of 2021, hitting historic snow maximums and temperatures. In the country, for the first time since 1964, television and newer communications are sending people cold snap warnings:

The situation is similar in Japan, where a new snow storm hit historic highs:

On January 7, the thermometer In Beijing dropped to -20 degrees Celsius, breaking the 1966 record. In other regions of China, the temperature is also not sugar, and you can only move around in special uniforms:

The cold even reached Taiwan, where the temperature in some areas dropped below freezing point, snow poured down and people realized that rice terraces can be used as a ski jump:

Even more snow went to Spain, where on January 6, 2021, a temperature of -34.1 ° C was recorded – the lowest on record. After that, a snow storm hit the country, which has not been seen for 80 years:

The same thing happens in Canada and in the northern states of the United States:

It seems that after a stratospheric warming, the subpolar vortex began to split:

The vortex itself is a standard phenomenon. However, this time experts were surprised at his movement. It is possible that in the near future it will be divided into two parts. 

Scientists associate the strange behavior with the changed climate in the Arctic, which has become warmer. From September to December, the amount of ice cover decreased significantly.

The polar vortex is a low-pressure region located in the stratosphere and filled with cold air. When the jet stream of air that holds the vortex weakens, the low pressure area moves south. 

As the ice shrinks, more moisture will move inland. It will turn to snow, so snowfalls are expected. Snow, in turn, reflects heat, leading to a cold snap.

Hospital in Naples was evacuated after a new, huge sinkhole appeared

Hospital in Naples was evacuated after a new, huge sinkhole appeared 97

Eyewitnesses said they heard a loud crash at dawn when a huge hole in the ground formed outside the Ponticelli Ospedale del Mare hospital in eastern Naples.

Early in the morning of January 8, 2021, a sinkhole occurred in the parking lot of a clinic in Naples. The depth of the formed cavity is about 20 meters, the total area of ​​the hole is about 2,000 square meters.

No casualties were found at the scene; firefighters say the sinkhole “affected an area of ​​about 500 square meters” and engulfed several cars parked near the hospital.

As the press writes and as a little can be seen from the videos, rescuers and firefighters were running around the pit together with the governor of the area.  But who should be there in the forefront are Italian geologists, since Naples stands in the very center of the volcanic system known as the Phlegrean Fields.

If the surface collapsed, moreover – the surface reinforced with concrete and reinforced from below with some kind of communications, then we are talking about serious soil deformations caused by the activity of magma.

Italy has been in doubt since the summer of 2020, because swarms were observed there in very atypical places in May, and according to the forecasts of old Italian seismologists, who had witnessed many strong earthquakes, it should have boomed in the August region.

Fortunately, nothing bad happened to Italy and there was no big earthquake. But, since there are swarms, it means that something is being prepared, the magma is gathering strength. 

Following this particular sinkhole event – an obvious sign that a major earthquake in Italy is already very close.

A new great pandemic cycle has begun (again) in China

A new great pandemic cycle has begun (again) in China 98

In the first months of 2020, the whole world with a certain fright followed the events unfolding in China, where people fell on the streets during the day and astronauts wandered, and in the evening crematoria began to smoke. And now, with the onset of December, the cycle seems to be repeating itself.

Shunyi area in Beijing, where the authorities announced “wartime status” the day before. As you can see in the videos, thousands of people are lined up in the queue for mandatory testing:

Dalian city, where “wartime” is also declared. Neighborhoods are blockaded, people are walled up in entrances, familiar characters of George Lucas roam the streets:

Chinese ‘rescuers’, before performing a combat mission:

Chengdu City:

Daluo Port, Yunnan – tourists came for adventure and they received the ‘time of their life’ after leaving the ramp:

If something happens in Beijing, it does not mean that tomorrow the same will happen everywhere. However, the trend towards such dynamics is observed and, as the practice of the first wave of the pandemic has shown, all countries and people, to one degree or another, have taken into account the ‘Chinese experience’. 

Therefore, one must think that everything will now be in peace, as in spring – a new global round of the fight against the Covid has begun in China, a new great pandemic cycle!
