The European Space Agency (ESA) managed to capture on video the incredible images of the Sun’s coronawhich show in exquisite detail the transition of the lower atmosphere of the Sol to the outer crown, much hotter. However, what is truly surprising are the phenomena captured that make the star appear “fluffy” and “hairy.”
ESA captures “hairy” and “fluffy” phenomena in the Sun’s corona
In the images taken by ESAthanks to Solar Orbiter, it is seen as if the Sun was full of “hair”. However, these structures that make it look “spongy” are made of charged gas (plasma), following magnetic field lines that emerge from the interior of the Sol.
An intriguing feature, which is visible throughout the video, is the glowing gas that forms delicate lace-like patterns around the Sun. According to the ESAthis is called coronal “moss”. It usually appears around the base of large coronal loops that are too hot or faint to see with your chosen instrument settings.

Furthermore, it is possible to observe in the solar horizon: needles of gas, known as spicules, which rise from the chromosphere of the Sol and they can reach up to a height of 10 thousand kilometers.

Other freak that it is possible to admire is a “small” rash in the center of the field of view, with cooler material rising upward before falling back down. Despite considering the eruption “small,” experts say that it is larger than the Tierra.

Refering to “cold” coronal rain As you can see, it looks dark against the bright background of large coronal loops. Rain is formed by accumulations of higher density plasma that fall towards the Sun under the influence of gravity.

According to the space agency, the brightest regions that can be seen in the images are around one million degrees Celsius, while the coldest material appears dark because it absorbs radiation.
The video was recorded on September 27, 2023 by the instrument Extreme Ultraviolet Imager (EUI) del Solar Orbiter, just when the spacecraft was about a third of the distance away from the Earth to the Sun, and was headed for a closest approach of 43 million kilometers on October 7.
Two missions on the Sun
On the same day this video was recorded, the NASA’s Parker solar probe moved to just 7.26 million kilometers from the solar surfacebut, instead of obtaining images directly from the Sol, Parker measured the particles and the magnetic field in the solar crown and in the solar wind.
This was a perfect opportunity for the two missions to team up, with the remote sensing instruments of the Solar Orbiter led by the ESA observing the region of origin of the solar wind which would later flow beyond Parker Solar Probe.

Volvo Cars Global Sales Soar 27% in April, Ex30 Model Leads the Way
Volvo Cars increased sales by 27 percent in April, reports the Swedish carmaker on Monday.

The number of global sales ended at 65,838, where the electronic models – both the hybrids all-electric and plug-in – accounted for 48 percent. The all-electric cars made up 26 percent of the total.
The sales growth was largely due to strong development in the European market and good sales of the EX30 all-electric SUV model.
In Europe, Volvo Cars sales grew by a whopping 65 percent, to 34,238 cars, with the EX30 being the best-selling model in the segment last month. Globally, the EX30 was Volvo Cars’ third best-selling car in April, behind the XC60 and XC40.
Anyway, the car was the best selling car model in Norway in April.
In the US, Volvo’s April sales growth was 10 percent slower, with the plug-in hybrids being the main contributor. In China, however, sales fell 3 percent compared to last April.
Volvo Cars’ share rose around 1 percent on the sales update. So far this year, Swedish car stocks are up about 16 percent.
On the way to the goal
– This result shows that we are making good progress with our guidance of sales growth of at least 15 percent for the full year 2024, says Björn Annwall, commercial director and deputy CEO of Volvo Cars.
In total so far in 2024, Volvo Cars has now sold 214,914 cars globally – an increase of 16 percent between January and April last year.
In comparison, the total number ended last year at 708,716, which was a new record for the company’s global sales.

Japan plans to start testing a drug to grow teeth
Japan – Scientists at the Japanese Kitano Institute for Medical Research plan to begin testing a drug to treat tooth aplasia next September.
The Japanese newspaper The Mainichi indicates that, according to scientists, this drug will practically be able to be used on a large scale after six years.
Dental aplasia causes a lack of teeth during the growth of the jaw bone at an early age, making it difficult to use dentures and dental implants. This innovative medicine affects tooth buds. As a result, it will be able to replace non-developing or fallen teeth.
The newspaper indicates that congenital hypodontia – the loss of 6 or more teeth is known as (oligodontia), and it is a hereditary condition that occurs in 1 percent of people.
According to the institute’s documents, men between the ages of 30 and 65 who do not suffer from obvious health problems and are missing one or more molars will be selected to test the innovative drug, where the drug will be injected intravenously. Testing will continue until August 2025.
The innovators say: “The tooth regrowth drug inhibits the activity of the USAG-1 protein, which prevents tooth growth. Therefore, in the future, it will be possible to implant teeth not only in people who suffer from congenital diseases, but also in those who have lost their teeth due to decay or injury.”
It should be noted that researchers tested the innovative drug on animals in 2018, and succeeded in growing teeth in mice and other rodents.
