The Earth was hit by the solar wind at a speed of 600 kilometers per second

We really do not live in peacetime. There is talk of extreme droughts, wars, fires, economic crises, and even in space, our star insists on whipping the planet with solar winds that surprise scientists who study these phenomena. The most recent case was a solar storm that hit Earth over the weekend. Without warning, the winds “hit” our planet in a completely unexpected way.

On Sunday, a stream of solar wind hit the Earth’s magnetic field, the speed of which reached more than 600 kilometers per second.

As we already mentioned, our star is in its 25th cycle, and when it began, the researchers left an alert that this new 11-year period will not be as calm as the last one, which ended at the end of 2019.

Some events, such as the M4.4 class solar flare or the X-class flare that occurred in 2021, show ongoing activity on our star. By the way, we saw that a G1 class storm was predicted last week. According to NOAA, this event, which reached us on August 3, did not cause any problems and its origin was associated with a hole in the sun. as explained here.

The Earth received an unexpected impact at a speed of more than 600 kilometers per second

Without warning, a strong gust of solar wind hit Earth last Sunday. While it's not all that alarming - solar storms often hit our planet and cause spectacular auroras - it's strange that this storm was completely unexpected.

This event was not in the forecast, so the auroras that arose came as a surprise.

informed SpaceWeather.

The solar wind occurs when a stream of high-energy particles and plasma can no longer be held by the Sun's gravity and erupts towards the Earth. Because how our Sun works is still largely unknown, these emissions are thought to come from large, bright spots on the Sun known as "corona holes." These events taking place on a star have been observed for a long time, and there is a lot of observational work being done here on Earth.

Through this attention to holes, scientists have been able to create "predictions" of space weather. They can already predict when these solar storms or solar flares, also known as coronal mass ejections (CMEs), will come our way. Plus, you can already see how powerful they will be.

However, this does not mean that the Sun does not surprise us and hit us without warning, as it did over the weekend.

But how was this effect of solar winds on our planet discovered?

Earlier Sunday, NASA's Deep Space Climate Observatory (DSCOVR) observed solar wind light streams that increased significantly and unexpectedly throughout the day. The cause of this solar storm is still unknown, but SpaceWeather suggests it may have been an early arrival of the solar wind, which is expected to come from an equatorial hole in the Sun's atmosphere two days later. Or it could be a lost coronal mass ejection (CME).

The inhomogeneity of the solar wind data at 00:45 UT on August 7 suggests a shock wave embedded in the solar wind.

Today, the active sun produces so many small explosions that it is easy to ignore the faint coronal ejections heading towards Earth.

This is how he described the SpaceWeather service.

It is interesting to note that as of today, August 9, the high-speed solar wind continues to beat the Earth's magnetic field, with records showing speeds as high as 551.3 kilometers per second. This new "attack" on our natural shield began this morning at 5 am.

The good news is that the solar wind is not harmful to us here on Earth. This is because we are safely protected by our planet's atmosphere.

However, when the "collision" is strong, our technologies can suffer from it. That's why they talk about it and we've seen it before problems with telecommunications satellites and, in extreme cases, with electrical networks.

Solar storm classified as G2

These winds have been classified as a moderate G2 solar storm - storms are classified as G1 at the bottom of the scale to G5 which is a powerful solar storm.

According to space meteorology, G2 storms can affect high-latitude energy systems and could impact spacecraft orbit forecasts.

In fact, it is already becoming a routine. This is due to the fact that this year there are especially many such events. However, as mentioned above, these 11 years of the 25th solar cycle will not be peaceful.

Google Maps launches immersive places to visit

Google will introduce new Google Maps features for those who want to travel and discover new places. The new items were announced during the Search On event by a North American technology company and promise to make our popular tool an even more useful resource.

The highlight on your navigation platform is now focused on how we oscillate between the real world and the virtual world. In particular, to move from a map to the real world to an appropriate representation of places of interest, areas to explore, and the entire environment.

The big novelty introduced now is the immersive look. This is a feature that was first showcased at the Google I/O conference earlier this year, but is now finally available for integration (although there is already talk of room for improvement). In practice, we will have a new way to visualize a certain point of interest through Google Maps.

Although in a virtual way, remotely and through a smartphone / tablet or PC, it becomes possible to get to know a certain area and everything that exists in the vicinity, which allows the user to “know the place” even before visiting it. When visiting, for example, a world-famous monument, we immediately find out what are the best restaurants nearby, the weather forecast for this place, and even where is the best place to take an Instagram photo.

There are currently 250 points available through the platform. The first regions to receive improvements are the United States of America, followed by Europe.

According to the company, this alliance is the result of comprehensive research and will appear at any time with access to locations.

The second new feature coming in the coming months is Neighborhood Vibe, which will help users feel the energy and vibe of the new neighborhoods they enter by displaying other users’ comments as they scroll through the Google Maps app.

Samsung: relatos de baterias inchadas em smartphones incomodam sul-coreana

Complaints about various models of smartphones are circulating on the Internet. Samsung with a painful problem: swollen battery. A video on the subject was posted last Tuesday, September 27th, on a technology channel known as mistertoboss. Video reached over 3 million views in just three days. This is not the first time a South Korean has been reported in this situation, but advances in technology should make such an incident more difficult.

Arun Mainithe person in charge of the channel stated that the situation could affect models available worldwide, such as Galaxy S6 (2015) Galaxy S10 (2019) and even Galaxy Z Add 2 (2020). Batteries “swell” after devices have been turned off for a certain period of time. This feature has not been found in other competing brands such as ASUS it’s in Apple.

Maini said the situation could affect models available around the world such as the Galaxy S6, Galaxy S10 and even the Galaxy Z Fold 2.

BUT Samsung sought out an influencer to clarify the situation, but did not publicly comment on what happened. The video that led to the complaint was this:

Android Police reports that other YouTubers have seen the same issue on Samsung smartphones.

According to tweet below, other influencers have noticed similar issues with the company’s mobile phones. Marques Brownlee (@MKBHD) wrote on his social media profile:

Evidence indicates that smartphones that are constantly used do not usually show signs of battery swelling; however, those that turn on after long periods of inactivity present the dangers described above. Arms mentioned that Samsung issued the following statement:

We are aware of this and are looking into further technical evaluations. Customers with questions about their Samsung device are advised to contact their local customer service representative.
