Volcano Tonga causes spectacular view in the skies of Antarctica



Volcano Tonga causes spectacular view in the skies of Antarctica

volcano Tonga still causing impacts around the world months after the eruption, and now scientists who are working on Antarctica took stunning pictures of the icy sky of the continent, which are its reflection.

As A photo were taken by New Zealand Antarctica technical scientist Stuart Shaw, who is stationed at Scott Base during the winter.


“Typically in the middle of winter in Antarctica it is almost always dark, with the exception of a slight “nautical twilight” around noon, which means that the horizon is faintly visible in good conditions. But this year we were treated to a real show where most of the station staff grabbed their jackets and ran outside with their cameras to see amazing colors. Believe it or not, I haven’t edited these photos either, they are very similar to the ones we saw. It’s amazing,” Shaw said. NIVA.

Check out some of the images Shaw took:

Shaw reportedly shared the footage after seeing stories of the pink sky phenomenon happening in New Zealand due to aerosols left in the stratosphere from the Tonga volcano eruption in January, which made him realize the same thing was happening in Antarctica.

According to Nava Fedaeff, NIWA meteorologist, satellite data indicate an abundance of aerosols in the stratosphere at an altitude of 15 to 24 km above Antarctica, which were not present before the Tonga eruption.

“Stratospheric aerosols can circle the globe for months after a volcanic eruption, scattering and bending light as the sun sets or rises below the horizon, creating a glow in the sky with shades of pink, blue, purple and purple,” the meteorologist explained. “This volcanic twilight is known as a ‘glow’, with color and intensity depending on the amount of haze and cloudiness in the path of light reaching the stratosphere.”

These aerosols are usually sulfate particles, but since the eruption occurred underwater, it is possible that there are water vapor droplets as well as sea salt. This is the same phenomenon as caused changes in the sky also here in Brazil.

Jordy Hendricks, Chief Scientific Adviser for Antarctica New Zealand, commented on the phenomenon. “Nature never stops putting on a show in Antarctica, and it can be beautiful or destructive,” he said. “These photographs capture the wonder it causes and how our planet is connected. Antarctica is about 5,000 km from New Zealand and about 7,000 km from Tonga, but we share the same sky.”

“What happens in Antarctica affects us at home and vice versa,” he continued. “Much of the science we support is focused on understanding these dynamics in the atmosphere, oceans and ecosystems and helping to better understand the connection between Antarctica and Earth. New Zealandand the whole world.”

Mathematical trick discovered that could revolutionize landings on the Moon and Mars



Imagem da Lua com detalhe

Space travel is a complex, confusing and dangerous topic. There are many variables that can turn a mission into a disaster. From launch to landing, everything must be very well planned, studied and simulated. Photographs taken by probes and robots can help, but they are far from the necessary information. However, all this may change with the advent of a new method of photomapping. A math trick will help you land safely on the Moon, Mars, and any other planet.

Landform mapping on our natural satellite is of great interest and importance for future human missions.

Photo mapping creates high-resolution surface maps

Researchers have discovered a method for creating high-resolution maps of the surfaces of planets such as the Moon by combining available images and topographic data.

Mapping the complex and varied surface of a world like the Moon at detailed resolution is challenging because laser altimeters, which measure changes in altitude, operate at a much lower resolution than cameras. And although photographs give a sense of surface features, it is difficult to translate images into a specific height and depth.

However, the new method combines topographic data with the degree of sunlight shading in optical images to provide a much more accurate assessment of fill shapes and structures. In the future, the development could help both astronauts and research robots.

The new method was developed by Iris Fernandes, a former PhD student at the Niels Bohr Institute at the University of Copenhagen, Denmark.

Lots of missions, lots of photos, but... lacks mathematical rigor

Different missions provide data at very different resolutions, so combining different data sources with different resolutions is a huge mathematical problem. Iris Fernandez and her then supervisor, geophysicist Klaus Mosegaard, did differently, as they focused on the mathematics of the problem, reducing the problem of determining whether an equation could solve the problem.

So it was. It can be said that my supervisor, Professor Klaus Mosegaard, and I have found the mathematical key to a door that has remained closed for many years.

Iris Fernandez mentioned in a statement about his discovery, published on the website university.

It should also be noted that the new approach also requires much less computing power and is much faster than previous methods, according to the researchers.

The moon was the first target of exploration

Researchers have demonstrated the technique on the moon. These combined high-resolution images from NASA's LROC camera Lunar Reconnaissance Orbiter with lower resolution spacecraft data Lunar orbiter laser altimeter (LOLA), the authors of the article claim to have increased the resolution of the topography from about 60 meters per pixel to 0.9 meters per pixel.

In this follow-up, the authors of the study noted that this method can be applied to extract accurate topographic information about rocks on planetary bodies such as the Moon, Mars, asteroids, and any other worlds for which topographic data is available.

This method can be used to solve a number of different problems, including determining the safety of astronauts and rovers or detecting geological points of interest, and can be applied to images from satellites, rovers, or other spacecraft.

The progress of the investigation is described in an article published on June 8 in the journal Planetary and space science.

Marco’s high school students made costumes for the Artamega show



Year 10 students of the Escola Secundária do Marco Professional Course in Fashion Design participated in the design of the costumes for the Artâmega – Marco de Canaveses Arts Conservatory show “Perhaps in the Heart”, filmed on stage at Sala Suggia, at Casa da Música, in Porto, July 9, 2022.

In a production technology class led by teacher Tanya Fernandez, more than 80 costumes were designed and made to match the characters from the various stories featured in the play.

The students made drawings that were transferred to the molds used to mark, cut and shape the fabric into pieces during the sewing process. “The teacher and students showed great dedication and effort, working tirelessly to complete all the work within the deadline”specifies an ad.

Artamega thanked “The opening and availability of the professional design and fashion course at Escola Secundária do Marco to participate in this wonderful project presented at Casa da Música, highlighting the importance of synergy, in this case between schools that are in the same space”ends.

Microsoft Brings New Latest System Feature to Windows 10



Windows 10 Windows 11 Microsoft novidades funcionalidades

While Microsoft is focused on its new system, Microsoft is committed to ensuring that Windows 11 continues to evolve. It will be supported for a few more years, so it should continue to receive news and improvements.

With what is being developed in Windows 11, there is an opportunity to bring these technologies to Windows 10. This will happen soon with the announcement of a new feature that will improve the printing experience in Windows 10.

Microsoft will mix features

Windows 11 is currently in development for Microsoft. This system is being improved and tries to give users as much functionality as possible, thereby ensuring that this is a modern system, as the best there is.

What seems logical is to combine efforts and include features in both Microsoft systems. So, what's next for Windows 10 is expected and important for its development, both for users and for what it offers them.

Windows 11 will contribute to Windows 10

In particular, Windows 10 will now be able to more precisely control the printing process. This will have a new control that will prevent fingerprints from being created without the user's permission, or from being accumulated without the user's explicit intention.

Windows 10 Windows 11 What's New Microsoft

This control will be as simple as using a PIN to block printing. Only after user authorization will the document be sent to the printer to be converted into a plain sheet of paper.

More news expected in the future

By introducing this new feature to Windows 10, Microsoft wants users to save paper and ink cartridges. At the same time, it provides greater security and guarantees user privacy, especially in environments with multiple printers.

Of course, this will only be the first moment when the functions of the two systems will be combined. Microsoft will certainly increase this proximity and thus guarantee users the maximum even faster.
