World’s largest iceberg breaks free, heads toward Southern Ocean

The world’s largest iceberg is on the move for the first time in more than three decades, scientists said on Friday.
At almost 4,000 square km, the Antarctic iceberg called A23a is roughly three times the size of New York City, Reuters reported.
Since calving off West Antarctica’s Filchner-Ronne Ice Shelf in 1986, the iceberg — which once hosted a Soviet research station — has largely been stranded after its base became stuck on the floor of the Weddell Sea.
Not anymore. Recent satellite images reveal that the berg, weighing nearly a trillion metric tonnes, is now drifting quickly past the northern tip of the Antarctic Peninsula, aided by strong winds and currents.
It’s rare to see an iceberg of this size on the move, said British Antarctic Survey glaciologist Oliver Marsh, so scientists will be watching its trajectory closely.
As it gains steam, the colossal berg will likely be launched into the Antarctic Circumpolar Current. This will funnel it toward the Southern Ocean on a path known as “iceberg alley” where others of its kind can be found bobbing in dark waters.
Why the berg is making a run for it now remains to be seen.
“Over time it’s probably just thinned slightly and got that little bit of extra buoyancy that’s allowed it to lift off the ocean floor and get pushed by ocean currents,” said Marsh. A23a is also among the world’s oldest icebergs, Reuters reported.
It’s possible A23a could again become grounded at South Georgia island. That would pose a problem for Antarctica’s wildlife. Millions of seals, penguins, and seabirds breed on the island and forage in the surrounding waters. Behemoth A23a could cut off such access.
In 2020, another giant iceberg, A68, stirred fears that it would collide with South Georgia, crushing marine life on the sea floor and cutting off food access. Such a catastrophe was ultimately averted when the iceberg broke up into smaller chunks — a possible end game for A23a as well.
But “an iceberg of this scale has the potential to survive for quite a long time in the Southern Ocean, even though it’s much warmer, and it could make its way farther north up toward South Africa where it can disrupt shipping,” said Marsh.

‘Massive cyberattack’ brings down Elon Musk’s X
Digital Trends reported Tuesday that there are reports suggesting X is still having issues

Social media platform X went down intermittently on Monday, with owner Elon Musk blaming an unusually powerful cyberattack.
“We get attacked every day, but this was done with a lot of resources. Either a large, coordinated group and/or a country is involved,” Musk said in a post on X on Monday.
He did not clarify exactly what he meant by “a lot of resources” and his comments drew skepticism from cybersecurity specialists, who pointed out that attacks of this nature — called denials of service — have repeatedly been executed by small groups or individuals.
X faced intermittent outages, according to Downdetector, Reuters reported.
Digital Trends meanwhile reported Tuesday that there are reports suggesting X is still having issues.
Internet industry experts have said X was hit by several waves of ‘denial of service’ throughout Monday.
Musk said in an interview with Fox Business Network’s Larry Kudlow the cyberattack came from IP addresses originating in the Ukraine area.
An industry source told Reuters he disputed Musk’s account, saying that large chunks of the rogue traffic bombarding X could be traced back to IP addresses in the United States, Vietnam, Brazil and other countries, and that the amount of rogue traffic coming directly from Ukraine was “insignificant.”
In any case, denial of service attacks are notoriously hard to trace back to their authors and the IP addresses involved rarely provide any meaningful insight into who was behind them, Reuters reported.
Musk has joined U.S. President Donald Trump, whom he serves as an adviser, in criticizing Ukraine’s continued efforts to fight off a Russian invasion.
Musk said on Sunday that Ukraine’s front line “would collapse” without his Starlink satellite communications service, though he said he would not cut off Ukraine’s access to it.

NASA says ‘city killer’ asteroid has a 3.1 % chance of striking Earth in 2032
Despite the rising odds, experts say there is no need for alarm

An asteroid that could level a city now has a 3.1-percent chance of striking Earth in 2032, according to NASA data released Tuesday — making it the most threatening space rock ever recorded by modern forecasting.
Despite the rising odds, experts say there is no need for alarm. The global astronomical community is closely monitoring the situation and the James Webb Space Telescope is set to fix its gaze on the object, known as 2024 YR4, next month.
“I’m not panicking,” Bruce Betts, chief scientist for the nonprofit Planetary Society told AFP.
“Naturally when you see the percentages go up, it doesn’t make you feel warm and fuzzy and good,” he added, but explained that as astronomers gather more data, the probability will likely edge up before rapidly dropping to zero.
2024 YR4 was first detected on December 27 last year by the El Sauce Observatory in Chile.
Astronomers estimate its size to be between 130 and 300 feet (40–90 meters) wide, based on its brightness. Analysis of its light signatures suggests it has a fairly typical composition, rather than being a rare metal-rich asteroid.
The International Asteroid Warning Network (IAWN), a worldwide planetary defense collaboration, issued a warning memo on January 29 after the impact probability had crossed one percent. Since then, the figure has fluctuated but continues to trend upward.
NASA’s latest calculations estimate the impact probability at 3.1 percent, up from 1.6 percent last month, with a potential Earth impact date of December 22, 2032.
Richard Moissl, head of the European Space Agency’s planetary defense office, which puts the risk slightly lower at 2.8 percent told AFP that this “is not a crisis at this point in time. This is not the dinosaur killer. This is not the planet killer. This is at most dangerous for a city.”
If the risk rises over 10 percent, IAWN would issue a formal warning, leading to a “recommendation for all UN members who have territories in potentially threatened areas to start terrestrial preparedness,” explained Moissl.
Unlike the six-mile-wide (10-kilometer-wide) asteroid that wiped out the dinosaurs 66 million years ago, 2024 YR4 is classified as a “city killer” — not a global catastrophe, but still capable of causing significant destruction.
Its potential devastation comes less from its size and more from its velocity, which could be nearly 40,000 miles per hour if it hits.
If it enters Earth’s atmosphere, the most likely scenario is an airburst, meaning it would explode midair with a force of approximately eight megatons of TNT — more than 500 times the power of the Hiroshima bomb.
But an impact crater cannot be ruled out if the size is closer to the higher end of estimates, said Betts.
The potential impact corridor spans the eastern Pacific, northern South America, the Atlantic, Africa, the Arabian Peninsula, and South Asia — though Moissl emphasized it is far too early for people to consider drastic decisions like relocation.
The good news: there’s ample time to act.
NASA’s 2022 DART mission proved that spacecraft can successfully alter an asteroid’s path, and scientists have theorized other methods, such as using lasers to create thrust by vaporizing part of the surface, pulling it off course with a spacecraft’s gravity, or even using nuclear explosions as a last resort. — Agence France-Presse

Panjshir will soon be connected to national fiber optic network
The statement said that this project covers a 36-kilometer route from Gulbahar to Bazarak, and the districts of Shatal, Anaba and Rukha will also benefit from fiber optic services.

The Panjshir provincial media office said in a statement on Wednesday, February 1 that practical work was to connect the province to fiber optic will begin within the next month.
The statement said that this project covers a 36-kilometer route from Gulbahar to Bazarak, and the districts of Shatal, Anaba and Rukha will also benefit from fiber optic services.
The statement added that the project is being implemented by Afghan Wireless, Afghan Telecom and ICG companies as a result of the efforts of the Panjshir provincial administration and the special attention of the leadership of the Ministry of Communications and Information Technology of the Islamic Emirate of Afghanistan.
