There have been many instances of asteroids passing by Earth in the last few weeks. Just yesterday, a 45 feet wide asteroid flew past the planet at a distance of approximately 3 million kilometers. Due to such close calls with asteroids, NASA, ESA, and other space agencies have developed technology to track these space rocks in their orbits, and even deflect them in case a potential impact scenario develops. Using its tech, NASA has now shed light on an asteroid that is expected to pass Earth today, January 23. Know all about this close approach.
Sun sparks solar storm, causes radio blackouts on Earth; NASA SDO reveals reason and affected regions
04.01.2024 - 06:48 / tech.hindustantimes.com / Sam Altman / An X (X) / Storm
On December 31, the Sun generated the strongest solar flare in 7 years and it was captured by the NASA Solar Dynamics Observatory (SDO). It originated from the same sunspot that hurled out another X2.8 solar flare on December 14. According to the National Oceanic and Atmospheric Administration (NOAA), this X-class solar flare also sparked radio blackouts. Now, it has been revealed that Earth is still reeling from the efforts of the solar storm thereby generated, and radio blackouts are still being observed. The regions specifically hit are in the Polar regions. The solar storm also generated some beautiful auroras in this region. Know all about it.
The solar flare hurled out by the Sun was of X5.0 intensity. The NOAA report states, “An X2.8 flare (R3) occurred from Region 3514; located over the far NW area of the Sun. This is likely one of the largest solar radio events ever recorded. Radio communication interference with aircraft were reported by multiple NWS Center Weather Service Units (CWSU) co-located at FAA facilities. These impacts were felt from one end of the Nation to the other. Additionally, SWPC is analyzing a possible Earth-directed Coronal Mass Ejection (CME) associated with this flare.”
For the unaware, X-class solar flares are the strongest in intensity and can create radiation storms that have the potential to harm the satellites. Moreover, these devastating flares can disrupt global communications and bring down the power grids to create blackouts.
A similar occurrence happened in the Polar regions, as the polar absorption event sparked by the X-class solar flare is still underway. According to a report by SpaceWeather, it has created a shortwave radio blackout in some areas. Frequencies below 35 MHz are being attenuated, while anything below 10 MHz is being completely blacked out. It has also been deemed one of the largest solar radio events ever recorded.
As per the report, the Protons hurled out towards Earth as a result of the solar flare eruption hitting Earth. While the planet's magnetic field protects it from most particles, they are funneled towards the poles, where they cause an ionizing effect, effectively absorbing shortwave radio waves.
After OpenAI stole the limelight, Google, Microsoft, Amazon and other Big Tech companies rushed muscled in on the Generative AI action.
The one thing that distracted everyone was the OpenAI sideshow that starred Sam Altman.

Solar storm danger: Sunspot ‘10 times wider than Earth’ could hurl out M-class solar flares
Earth witnessed f X-class solar flares a number of times in the last few months. For the unaware, X-class solar flares are the most intense flares which can result in long-lasting radiation storms. In December, there were two instances of terrifying X-class solar flares hitting the planet, one of which caused a radio blackout in the polar regions for almost 3 days. Now, another solar storm danger has been highlighted as a massive sunspot on the solar surface could hurl out M-class solar flares towards Earth. Know all about this solar storm danger.

130-foot asteroid to come as close as 1.5 mn km to Earth; NASA reveals speed, and other details
Did you know that not all asteroids have the same composition? According to NASA, the three primary classifications of asteroids are C-type, S-type, and M-type. C-type asteroids, which are composed primarily of carbon-rich substances, are the most frequent. S-type asteroids, which are made up mainly of silicate minerals, are less common. M-type asteroids, which are primarily composed of metal, are the least prevalent. One asteroid, whose composition is still unknown, is set to pass Earth today, January 18.
