Scientists scoping out a star system in the constellation Orion have witnessed one of the most gargantuan and powerful stellar flares ever seen.

Dubbed a “superflare,” the enormous blast of stellar radiation is 10 times more massive than anything ever witnessed erupting from the sun, according to new research published in The Astrophysical Journal (opens in new tab) . 

While the mechanism behind these monster flares still isn’t well understood, the new research suggests that superflares originate from stars that are highly magnetically active. These superflares may be accompanied by enormous eruptions of charged particles that could devastate life on any planets in their firing line, the study authors wrote. (Fortunately for us, Earth is not one of those planets.)

In their new research, the astronomers targeted a star system called V1355 Orionis, which is about 400 light-years from Earth and features two stars orbiting each other. These stars belong to a class of stars known to harbor many sunspots — dark, planet-size regions that form as the result of intense electromagnetic activity — and that have been tied to other observed superflares. 

In general, stellar flares occur when magnetic-field lines in a star’s atmosphere tangle, snap and reconnect, releasing a powerful gout of radiation that’s visible across the entire electromagnetic spectrum. On the sun, flares may be accompanied by towering loops of plasma, known as prominences, that can rise tens of thousands of miles above the sun’s surface. If this solar plasma launches quickly enough, it can break free of the sun and become a coronal mass ejection (CME) — an enormous blob of high-energy particles that can knock satellites out of orbit and short-circuit power grids on Earth, if our planet happens to be in the blob’s path. 

Combining observations from the Transiting Exoplanet Survey Satellite and the Seimei Telescope in Japan, the researchers studied the distant star system in multiple wavelengths of light to capture the most complete picture possible of the superflare’s evolution. —1 million-mile-long plasma plume shoots out of the sun in stunning photo

They found that the flare began with one of the most powerful stellar eruptions ever seen — a high-velocity prominence that burst out of one of the stars at more than 2.2 million mph (3.5 million km/h). This blast far exceeded the star’s escape velocity, launching trillions of tons of electrically charged matter outward into space in what may be one of the largest CMEs ever observed, the authors wrote.

It’s not certain how, exactly, such a powerful CME would impact life on any hapless planets that got in the way — but the researchers said the effects would be far more catastrophic than those associated with even the worst CMEs to hit Earth. 

Ultimately, this mega-flare’s discovery is less a cautionary tale for our planet than it is a caveat in the search for life on other worlds: Planets around magnetically hyper star systems like V1355 Orionis may not be the best places to look.

Britain’s winter blackout risk the lowest in six years – but ‘tight’ days expected

Britain's winter blackout risk the lowest in six years - but 'tight' days expected

Britain is at the lowest risk of a winter power blackout than at any point in the last six years, the national electricity grid operator has said.

Not since the pre-pandemic winter of 2019-2020 has the risk been so low, the National Energy System Operator (NESO) said.

It’s thanks to increased battery capacity to store and deploy excess power from windfarms, and a new subsea electricity cable to Ireland that came on stream in April.

The margins between expected demand and supply are now roughly three gas power stations greater than last year, the NESO said.

Renewables overtake coal for first time

It also comes as Britain and the world reached new records for green power.

For the first time, renewable energy produced more of the world’s electricity than coal in the first half of 2025, while in Britain, a record 54.5% of power came from renewables like solar and wind energy in the three months to June.

More renewable power can mean lower bills, as there’s less reliance on volatile oil and gas markets, which have remained elevated after the invasion of Ukraine and the Western attempt to wean off Russian fossil fuels.

“Renewables are lowering wholesale electricity prices by up to a quarter”, said Jess Ralston, an energy analyst at the Energy and Climate Intelligence Unit (ECIU) thinktank.

In a recent winter, British coal plants were fired up to meet capacity constraints when cold weather increased demand, but still weather conditions meant lower supply, as the wind didn’t blow.

Those plants have since been decommissioned.

But it may not be all plain sailing…

There will, however, be some “tight” days, the NESO said.

On such occasions, the NESO will tell electricity suppliers to up their output.

The times Britain is most likely to experience supply constraints are in early December or mid-January, the grid operator said.

The NESO had been owned by National Grid, a public company listed on the New York Stock Exchange, but was acquired by the government for £630m in 2023.

Man Utd and chemicals boss warns of ‘moment of reckoning’ for his industry

Man Utd and chemicals boss warns of 'moment of reckoning' for his industry

Sir Jim Ratcliffe, the co-owner of Manchester United and head of Ineos, one of Europe’s largest chemical producers, has staged an “11th-hour intervention” in an effort to “save” the chemical industry.

Sir Jim has called on European legislators to reduce price pressures on chemical businesses, or there “won’t be a chemical industry left to save”.

“There’s, in my view, not a great deal of time left before we see a catastrophic decline in the chemical industry in Europe”, he said.

The “biggest problem” facing businesses is gas and electricity costs, with the EU needing to be “more reactive” on tariffs to protect competition, Sir Jim added.

Prices should be eased on chemical companies by reducing taxes, regulatory burdens, and bringing back free polluting permits, the Ineos chairman and chief executive said.

It comes as his company, Europe’s biggest producer of some chemicals and one of the world’s largest chemical firms, announced the loss of 60 jobs at its acetyls factory in Hull earlier this week.

Cheap imports from China were said to be behind the closure, as international competition facing lower costs has hit the sector.

What could happen?

Now is a “moment of reckoning” for Europe’s chemicals industry, which is “at a tipping point and can only be saved through urgent action”, Sir Jim said.

European chemical sector output declined significantly due to reduced price competitiveness from high energy and regulatory costs, according to research funded by Ineos and carried out by economic advisory firm Oxford Economics.

The report said the continent’s policymakers face a “critical” decision between acting now to safeguard “this vital strategic industry or risk its irreversible decline”.

As many as 1.2 million people are directly employed by chemical businesses, with millions more supported in the supply chain and through staff spending wages, the Oxford Economics report read.

Average investment by European chemical firms was half that of US counterparts (1.5%, compared to 3%), a trend which is projected to continue, the report added.

Jays knock out Yankees, reach 1st ALCS since '16

NEW YORK — Vladimir Guerrero Jr. and George Springer each drove in a run, and eight Toronto pitchers shut down the New York Yankees in a 5-2 victory Wednesday night that sent the Blue Jays to the American League Championship Series for the first time in nine years.

Nathan Lukes provided a two-run single and Addison Barger had three of Toronto’s 12 hits as the pesky Blue Jays, fouling off tough pitches and consistently putting the ball in play, bounced right back after blowing a five-run lead in Tuesday night’s loss at Yankee Stadium.

AL East champion Toronto took the best-of-five Division Series 3-1 and will host Game 1 in the best-of-seven ALCS on Sunday against the Detroit Tigers or Seattle Mariners.

Those teams are set to decide their playoff series Friday in Game 5 at Seattle.

Ryan McMahon homered for the wild-card Yankees, unable to stave off elimination for a fourth time this postseason as they failed to repeat as AL champions.

Despite a terrific playoff performance from Aaron Judge following his previous October troubles, the 33-year-old star slugger remains without a World Series ring. New York is still chasing its 28th title and first since 2009.
