Asteroid will pass in front of bright star Betelgeuse to produce rare eclipse visible to millions
One of the biggest and brightest stars in the night sky will momentarily vanish as an asteroid passes in front of it to produce a one-of-a-kind eclipse.
The rare and fleeting spectacle, late Monday into early Tuesday, should be visible to millions of people along a narrow path stretching from central Asia’s Tajikistan and Armenia, across Turkey, Greece, Italy and Spain, to Miami and the Florida Keys and finally, to parts of Mexico.
The star is Betelgeuse, a red supergiant in the constellation Orion. The asteroid is Leona, a slowly rotating, oblong space rock in the main asteroid belt between Mars and Jupiter.
Astronomers hope to learn more about Betelgeuse and Leona through the eclipse, which is expected to last no more than 15 seconds. By observing an eclipse of a much dimmer star by Leona in September, a Spanish-led team recently estimated the asteroid to be about 34 miles wide and 50 miles long (55 kilometers wide and 80 kilometers long).
There are lingering uncertainties over those predictions as well as the size of the star and its expansive atmosphere. It’s unclear if the asteroid will obscure the entire star, producing a total eclipse. Rather, the result could be a “ring of fire” eclipse with a miniscule blazing border around the star. If it’s a total eclipse, astronomers aren’t sure how many seconds the star will disappear completely, perhaps up to 10 seconds.
“Which scenario we will see is uncertain, making the event even more intriguing,” said astronomer Gianluca Masa, founder of the Virtual Telescope Project, which will provide a live webcast from Italy.
An estimated 700 light-years away, Betelgeuse is visible with the naked eye. Binoculars and small telescopes will enhance the view. A light-year is 5.8 trillion miles.
Betelgeuse is thousands of times brighter than our sun and some 700 times bigger. It’s so huge that if it replaced our sun, it would stretch beyond Jupiter, according to NASA.
At just 10 million years old, Betelgeuse is considerably younger than the 4.6 billion-year-old sun. Scientists expect Betelgeuse to be short-lived, given its mass and the speed at which it’s burning through its material.
After countless centuries of varying brightness, Betelgeuse dimmed dramatically in 2019 when a huge bunch of surface material was ejected into space. The resulting dust cloud temporarily blocked the starlight, NASA said, and within a half year, Betelgeuse was as bright as before.
Scientists expect Betelgeuse to go supernova in a violent explosion within 100,000 years.

South Korea authorities launch probe after three die in Hyundai car test
The Ulsan plant is Hyundai’s biggest manufacturing facility, with its own port and an annual production capacity of 1.4 million vehicles
South Korean authorities launched an investigation on Tuesday after three people died during a car test at a Hyundai Motor plant in the city of Ulsan, police told Reuters.
The two Hyundai researchers and one Hyundai contractor were found unconscious in a car at around 3:00 p.m. while they were testing it in a "chamber," according to Hyundai's labour union.
South Korean media reports said the three had suffocated.
A police officer in Ulsan said the police and the labour ministry were investigating the incident, including its cause.
A fire department official told Reuters that it first received a report at 3:17 pm that the accident happened at Hyundai's No.4 factory.
"Hyundai Motor Company is deeply saddened by the incident that occurred at our plant in Ulsan, South Korea," Hyundai said in a statement, saying it would "cooperate fully with all relevant authorities to determine the cause of this incident."
The Ulsan plant is Hyundai's biggest manufacturing facility, with its own port and an annual production capacity of 1.4 million vehicles, including exports of 1.1 million units.
In November last year, Hyundai Motor broke ground on a 2 trillion won ($1.44 billion) plant in Ulsan dedicated to making electric vehicles in South Korea, as the automaker accelerated a shift away from petrol-powered cars.

Russia fines Google more than the world’s total GDP over YouTube bans
Russia has fined Google $2.5 decillion after the US tech giant took action against pro-Kremlin TV channels on YouTube following Moscow’s invasion of Ukraine.
Russia imposed a daily fine four years ago - a fine that has since swelled to an unprecedented level - ($20,000,000,000,000,000,000,000,000,000,000,000 - a 33-digit figure).
To put this into perspective, global GDP reaches an estimated $110 thousand billion (12-digit figure), according to the IMF.
Speaking to Russia’s TASS news agency, one expert, Roman Yankovsky from the HSE Institute of Education, said Google “clearly will not pay this penalty, and the Russian Federation will not be able to recover this money from the company."
Euronews reported that a short calculation shows that he is right.
Google's holding company, Alphabet, has a market capitalisation of slightly more than $2 trillion. Even with earnings of $80.54 billion from the last quarter, the tech giant doesn’t seem to be able to afford to pay the fine.
Google first barred pro-Moscow channel Tsargrad TV, which is owned by oligarch Konstantin Malofeev, four years ago.
At the time, Google was fined a daily penalty of 100,000 roubles and warned that amount would double every 24 hours if it went unpaid.
The original fine has been compounded by further penalties after Google eventually blocked a total of 17 Russian TV channels as a result of international sanctions, The Telegraph reported.
The tech giant now owes a staggering $2.5 decillion.

Apple launches new iPad mini with AI features
Apple said it would roll out the first set of AI features in the U.S. version of the English language this month through a software update with iPadOS 18.1.
Apple on Tuesday launched its new generation of the iPad mini packed with AI features including writing tools and an improved Siri assistant, as the iPhone maker races to boost its devices with artificial-intelligence capabilities, Reuters reported.
The new iPad mini is powered by Apple's A17 Pro chip, which is used in the iPhone 15 Pro and Pro Max models. With a six-core central processing unit, the A17 Pro would boost CPU performance by 30% compared to the current generation iPad minis and is central to running Apple Intelligence, Apple's AI software.
Apple said it would roll out the first set of AI features in the U.S. version of the English language this month through a software update with iPadOS 18.1.
The features will be available for iPads with A17 Pro or M1 chips and later generations, Apple said, adding it will roll out additional features including image-generation tools, Genmoji and ChatGPT-powered capabilities over the next several months, read the report.
Apple in September unveiled its long-awaited, AI-boosted iPhone 16 lineup, but with the AI features still in test mode, the company failed to excite some investors while early sales data raised some questions around demand.
Still, research firm Canalys on Monday said the iPhone 16 would help Apple's sales in the fourth quarter and drive momentum into the first half of 2025, after Apple reached a record high third-quarter shipments.
The iPad mini, starting at $499, is available for pre-orders starting on Tuesday and will begin arriving to customers and Apple store locations next week, Apple said.
