LOS ANGELES, Jul. 12 (Xinhua) — NASA on Tuesday released the first color images from the James Webb Space Telescope and its spectroscopic data, revealing unprecedented and detailed views of the universe.

According to NASA, Webb’s first observations tell the story of the hidden universe at every stage of cosmic history, from nearby exoplanets to the most distant observable galaxies in the early universe.

“Today, we bring humanity a groundbreaking look at space from the James Webb Space Telescope, a view the world has never seen before,” said NASA Administrator Bill Nelson.

Images released by NASA include a detailed spectrum of the exoplanet’s atmosphere; the South Rim Nebula, an expanding cloud of gas surrounding a star about 2,000 light-years away; Stephen’s Quintet, a compact group of galaxies located in the constellation Pegasus; The Carina Nebula, the first rapid phases of star formation that were previously hidden.

On Monday, US President Joe Biden released another image created by Webb, the galaxy cluster SMACS 0723, which is filled with thousands of galaxies, including the faintest objects ever observed in infrared.

“These images, including the deepest look at our universe ever taken, show us how Webb will help us find answers to questions we don’t even know yet; questions that will help us better understand our universe and the humanity in it.” , Nelson said.

The publication of Webb’s first images and spectra marked the beginning of Webb’s science endeavors, where astronomers around the world will be able to observe anything from objects in the solar system to the early universe using four of Webb’s instruments, according to NASA.

Webb was launched from the Guyana Space Center in Kourou, French Guiana on December 25, 2021 to investigate the structure and origin of the universe.

After completing a complex sequence of deployments in space, Webb went through months of commissioning where his mirrors were aligned and his instruments were calibrated for the space environment and prepared for science.

Webb is the largest and most powerful NASA space science telescope ever built. With a 6.5-meter primary mirror, the large infrared telescope will study all stages of cosmic history, from the solar system to the most distant observable galaxies in the early universe, according to NASA.

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.

Samsung plans to release a tablet with a folding screen



Samsung plans to release a tablet with a folding screen

BUT Samsung has already made it clear that it intends to continue betting on foldable phones, which will include the company’s new Galaxy Z Fold 4 and Galaxy Z Flip 4 models this week.

Apart from wanting to contribute to the foldable mobile phone category, a South Korean tech company is also known to be developing a foldable screen tablet. Who says this is the Ice Universe page on the Chinese social network Weibo (via Android Headers), referring to the fact that the tablet in question will be called the Galaxy Tab Fold.

The page in question suggests that the Galaxy Tab Fold will be announced at the same Galaxy Tab S9 launch event that Samsung usually holds in the first quarter of the year.

It is possible that the presentation of these two tablets will take place in early 2023, but given that we had to wait two years between the Galaxy S7 (2020) and Galaxy S8 (2022), there is also a possibility that the Galaxy Tab Fold and Galaxy Tab S9 will appear only in 2024.
