Photos show the spectacle of the northern lights as a result of solar storm G3.

Last few days The Earth was affected by a solar storm resulting from an M-class eruption at AR3078.. Several organizations have warned of the possibility that the solar storm will reach G3 levels, which are considered strong.which caused some problems in the technological equipment, but also increased the number of auroras and expanded the latitudes where they could be observed.

The result is displayed in photographs hosted on various platforms, which show impressive images of the Northern Lights, also known as the Northern Lights, and light effects in the night sky.

astronaut Samantha Cristoforetti, on the International Space Station’s Minerva mission, says it’s the most spectacular auroras she’s seen in more than 300 days in space.

New peak of solar activity began last week, and from August 18 to 23, one of the most moderate storms wreaked havoc. Some meteorological authorities such as the US National Oceanic and Atmospheric Administration (NOAA) Weather Forecast Center, the Australian Bureau of Meteorology (BOM) and the British Met Office. issued a warning of new G3 storms effective August 18 and 19..

Solar storms are caused by one of the sunspots that produced several class M eruptions, but this year there were episodes reaching class X. Solar flares are common and are part of the life cycle of the Sun, which has several activity phases over an 11-year period with sunspots and coronal activity. The Sun is currently in an ascending cycle of this activity, which should peak in July 2025.

Class M eruptions emitted by sunspot AR3078 could impact the Earth if they are oriented in that direction, with plasma and magnetic fields ejected into space collide with the planet’s magnetic field and atmosphere, resulting in a geomagnetic storm.

The classification of storms varies by severity, with a light storm rated G1 and a moderate storm G2, with the strongest rated G3 to G5. Warnings issued by NOAA indicate that this is a G3 storm.

Even the weakest storms can cause fluctuations in the power grid, which will also affect the migration of some animals and the operation of satellites. For moderate storms voltage alarms on transformers and satellite routing may need to be corrected.while the HF radio operation may be interrupted.

One of The most spectacular effects that skywatchers have come to expect are the northern lights., which result from the arrival of particles in the Earth’s magnetosphere, accelerating the magnetic field and causing a color effect in the atmosphere, also known as the northern lights. These phenomena are usually visible in regions closer to the north and south poles, but during solar storms the field of view can extend to lower latitudes.

O astronaut Bob Hines already had the ability to record from the space station some of the effects of these auroras are being shared on Twitter, and Italian astronaut Samantha Cristoforetti shared photos of herself yesterday, saying they are the most impressive auroras she has seen in over 300 days in space.

[아하! 우주] China launches ‘two spaceships’ with rocket to explore Jupiter and Uranus: ZUM News

China is planning an ambitious “one stone and two birds” project for the outer planets of Jupiter and Uranus, launching a pair of spacecraft simultaneously with a single rocket around 2030.

The mission is called Tianyuan 4, and the two largest Jupiter-bound probes will be sent to Uranus, while a smaller spacecraft will be sent to explore Uranus.

Launched simultaneously by Changjun 5 rockets, the pair use two flybys of Venus and two flybys of Earth to place the spacecraft on an outer solar system trajectory before determining their intended paths.

China previously said it was in the planning stages of Jupiter exploration, but at the 2022 International Space Conference in Paris on Sept. 21, Wang Qiong of the China National Aeronautics and Space Administration (CNSA) announced the establishment of a new Center for Space Technology and Lunar Exploration. . Details.

The main spacecraft will be designed to study the Jupiter system and eventually enter orbit around Callisto to explore its more distant Galilean moons.

According to the CNSA statement, a small spacecraft weighing a few hundred kilograms will make a long journey to Uranus, indicating that the spacecraft could fly close to the asteroid on its way away from the Sun.

“Scientific targets are still being explored,” CNSA’s Wang Qiong said after the presentation. Previous announcements have focused on extensive surveys of Callisto as the main target, which could reveal much about the history of the Moon and Jupiter, or irregular satellite surveys of Jupiter, which could provide insight into the solar system’s early days.

CNSA had previously considered landers as part of the Carilsto-focused mission profile, but Wang says the latest concept does not include landers other than orbital ones.

Meanwhile, China launched its first independent interplanetary mission in 2020, sending the Tianyuan-1 orbiter and Colony spacecraft to Mars.

Tienwon 2 will launch around 2025 and land on Kamo’oalewa, an underground satellite orbiting the Sun in Earth orbit, collecting samples and returning around 2026.

Tianyuan 3 will be a complex double-launched modular Mars return mission, expected to deliver the first samples collected from Mars to Earth as early as 2028.

Wang also added that with the plan to build an international lunar research base in the 2030s, “the goal is to promote the use of manpower, create a new kind of international cooperation in space exploration, and promote the peaceful use of spacecraft.” space”.

Microsoft improves Windows 11 update process

Published

on

Windows 11 users can always and automatically receive updates from Windows Update, but it looks like Microsoft is testing how to improve this system in the future.

With the release of the new version of Windows 11 22H2, Microsoft has confirmed that it also improves the Windows Update system, making it more stable and reliable, as well as preventing possible errors that may occur in the process.

According to the company, one of the first changes concerns the size of the updates themselves, which should now be significantly smaller. This allows users to download updates faster, but also reduces data consumption. What’s more, by focusing only on core components, users resent updates that are less likely to fail.

Another novelty is aimed at reducing Microsoft’s carbon footprint: the operating system now determines the best time to install updates in order to be as efficient as possible. In this case, Windows starts installing updates at a time when it is more appropriate for the use of “clean energy”.

All of these news should be found on Windows 11 22H2. This update from Microsoft is available to all users who are considered “crawlers” – those who manually search for updates through “Settings”.

If you don’t get it, try searching Windows Update a few times.

NASA will destroy the spacecraft against the asteroid - to see if it can protect the planet

The US space agency’s experiment, scheduled for the early hours of Monday, is aimed at assessing whether an asteroid that is on a collision course with Earth can be deflected.

NASA spacecraft will collide with the asteroid at dawn on Monday.

DART, short for “Dual Asteroid Redirection Test”, will encounter a space rock after launching 10 months ago. ship crash into the moon an asteroid to see how it affects the movement of this cosmic body.

The mission is heading towards Dimorphos, a small moon orbiting the asteroid Didymos. The asteroid system poses no threat to Earth, NASA says, making it an ideal target for a kinetic impact test, which could be necessary if one day an asteroid is on a collision course with Earth.

The event will be the first large-scale demonstration of sabotage technologies capable of protecting the planet. Collision is expected at 00:14 Monday.

At this time, Dimorphos will be relatively close to the Earth – within a radius of 11 million kilometers. In a collision with an asteroid, the spacecraft will accelerate to 24,140 kilometers per hour.

“For the first time, we will significantly change the orbit of a celestial body in the universe,” said Robert Brown, head of space science at the Applied Physics Laboratory at Johns Hopkins University.
