The Longest Night: A Short Guide to the Winter Solstice

The winter solstice arrives later this month, and here’s what that means.

For many people in the US, winter has come a little early, as a few waves of snow and blisteringly cold temperatures have colored the landscape white. It isn’t officially winter yet, and it won’t be until Dec. 21 when the winter solstice takes place. So get ready because Earth’s shortest day is on its way.

What is the winter solstice?

The winter solstice has a few different meanings, so here are all of them. The most common definition, and the one you’re most likely familiar with, is that it denotes the shortest day and longest night of the year on Earth. These times vary depending on your location on the globe, but the further north you live, the less sunlight you’ll get. In the tropics, they’ll get about 12 hours of sunlight. In Sweden, it’ll be closer to six hours. In Svalbard, there isn’t any.

The reason this occurs is due to the second definition of the winter solstice: During this time, the North Pole is tilted as far away from the sun as it can get. According to The Farmer’s Almanac, the moment at which the Earth’s axis is physically tilted as much as it can be is at 10:03 a.m. ET on Dec. 21. After that moment, the process will begin to reverse until the South Pole takes its turn during the summer solstice. At that point, the North Pole will be at its closest tilt to the sun, giving us the longest day and shortest night of the year for the Northern Hemisphere.

How much sunlight will we get?

It’ll vary by location. The southern US will have the most sunlight, with Florida getting a little over 10 hours during the winter solstice. The Midwest and Great Lakes portion of the country will get roughly nine hours. The Pacific Northwest can expect a little less than nine hours. Southern Alaska will get about six hours, and the northern areas of Alaska will see around three hours.

The city of Utqiaġvik, Alaska, will have it worse than most in the US: It won’t get any sun at all. The sun won’t rise there again until Jan. 22. We hope the people living there packed their vitamin D supplements.

The difference between a solstice and an equinox

The autumn equinox was just a few months ago, so you may be curious about the differences. A solstice occurs when the Earth’s poles are tilted as far away from the sun as they’ll be over the course of one year, which is also one orbit around the sun. The equinoxes take place at the halfway points between each solstice. The autumn equinox takes place in September between the summer and winter solstices, while the spring equinox takes place in March between the winter and summer.

During an equinox, the poles are minimally tilted, and the days are as even as they can be. This also has a couple of other interesting side effects: The sun is pointed directly at the equator during an equinox, and the sun will rise and set directly east and west, respectively.

Humans use the solstices and equinoxes to mark the change of the seasons. There are two equinoxes and two solstices, which mark the start and end dates for Earth’s four seasons.

Celebrating the winter solstice

While the solstice is close to the holidays, celebrations for the winter solstice have been around for significantly longer, and some winter solstice traditions have become Christmas traditions as well. One of the most historically famous winter solstice celebrations is Yule, a winter festival originating thousands of years ago among the Ancient Norse. It became commonly celebrated in Europe and involved bonfires and massive feasts. Yule celebrations also included decorating with evergreen tree decorations, like holly and ivy.

If these sound familiar, it’s because Christmas co-opted many of those traditions centuries ago, and the two traditions have kind of merged into a single seasonal holiday. The terms Yule and Christmas are often used interchangeably these days in many cultures.

So if you want to celebrate the winter solstice, just do all of the stuff you would normally do for the holidays. Burn a Yule log, decorate a tree, eat a big feast with your family and hang up mistletoe and wreaths — those are all hat tips to traditional winter solstice celebrations.

Passengers and crew foil co-pilot’s apparent attempt to crash FlyDubai flight to Israel

One of the pilots on a FlyDubai flight headed for Israel stabbed the second pilot, according to Israeli Prime Minister Benjamin Netanyahu.

On-duty flight crew and passengers managed to foil a pilot’s apparent attempt to crash a FlyDubai flight, after reports emerged of a fight in the cockpit.

The incident on flight FZ1073 from Dubai to Tel Aviv happened when a co-pilot stabbed a pilot, according to Israeli Prime Minister Benjamin Netanyahu, who praised the victim’s quick thinking.

“Despite being stabbed and seriously injured, he fought back, resisted, opened the cockpit door, and enabled passengers and crew to overpower the attacker — preventing a catastrophic mid-air disaster. He saved the lives of 174 people, including Israeli citizens and other nationals,” Netanyahu wrote in a post on X.

FZ1073 was diverted to the Tabuk airport in Saudi Arabia, the airline said, after being successfully secured and diverted by flight crew.

FlyDubai in a statement said that an “altercation” occurred on the flight deck of the plane, but did not mention a stabbing.

However, the airline added that the underlying reasons and motives for the clash is currently unknown, urging all parties to refrain from speculation.

The injured pilot was identified by Netanyahu as Indian national Smit Machchhar. No details have been released on the identity of the attacker, except that he was being interrogated by Saudi authorities.

The Indian embassy in Riyadh said on X that Machchhar is in a hospital in Tabuk, and is reported to be in stable condition.

The Israeli Prime Minister also identified the passenger who broke into the cockpit as Yaniv Hayun, calling him a “hero” and adding he deserved “a global medal of honor.”

Flight data from tracking site FlightRadar24 showed that the plane had experienced extreme altitude fluctuations before broadcasting a “general emergency” squawk code.

FZ1073 had dropped from over 14,000 feet in just 29 seconds, and FlightRadar24 also added that vertical speeds ranging from approximately -30,000 to +10,000 feet per minute were observed from the transponder data.

For context, vertical speeds during normal operations rarely exceed plus or minus 4,000 feet per minute, it added.

South Korean President Lee resists Alaska LNG project after Trump highlights Seoul’s involvement

South Korean President Lee Jae‑myung has conditioned his country’s participation in the Alaska LNG project on financial viability and legal compliance, pushing back against President Trump’s push for the $50‑billion venture while other $200‑billion U.S. investments move forward.

South Korea’s $200 billion investment in the United States, which President Donald Trump said would transform America “for generations,” is not yet finalized in full.

The South Korean investment blueprint includes nuclear power plants, a natural‑gas power facility in Texas, and potentially the long‑planned Alaska liquefied natural gas project.

Trump posted on Truth Social late Wednesday that the two nations had agreed to move forward on the Alaska LNG venture, estimating its value at $50 billion. This prompted a response from South Korean President Lee Jae‑myung, who stressed that participation in some projects remains tied to commercial considerations.

In an X post Thursday local time, Lee said that involvement in the Alaska LNG project hinges on its financial viability and legal compliance. He added that investments in nuclear power plants would also require a plant‑by‑plant assessment of commercial feasibility.

The US‑South Korea joint statement Wednesday also noted that work on the project is contingent on “commercial reasonableness,” without detailing allocations toward the venture.

The Alaska LNG project aims to move natural gas roughly 1,300 km (800 miles) from fields on Alaska’s North Slope to the state’s southern region, where it would be liquefied for export to markets including Asia, according to Yonhap. The initiative has long faced scrutiny over its economics, given the substantial upfront capital required.

Industry Minister Kim Jung‑kwan labeled it “high‑risk” last year and said participation would be challenging unless the project could generate sufficient cash flow.

Overall, the investment package allocates $22.3 billion for a 6,472‑megawatt natural‑gas power plant in Encinal, Texas, which will supply electricity to nearby data centers. The venture will be led by developer Related Cos. and U.S. power provider NextEra Energy.

Trump said the investments would turn South Korea’s commitments into “huge construction projects” and create “tens of thousands of American jobs.”

“These are massive energy projects, adding power capacity in the United States,” Trump remarked. “This is new construction, new manufacturing, and great jobs for American workers.”

The two countries said they would seek to broaden Korean firms’ involvement in the Texas project across equipment supply, engineering, construction, and long‑term operations and maintenance. The U.S. also plans to give Korean companies opportunities to supply equipment, including turbines, for similar projects domestically.

Another $120 billion has been earmarked for plans to build eight large‑scale nuclear reactors in the United States. Of that sum, $100 billion is designated for construction costs and $20 billion for contingency reserves.

The nuclear accord was signed by both governments as well as Westinghouse Electric, Korea Electric Power Corp., and Korea Hydro & Nuclear Power. The plan also calls for Korean firms to pursue a potential significant minority stake in Westinghouse, with terms subject to commercial negotiations.

Washington’s big crypto bill is stuck. The SEC is pushing ahead anyway

The SEC has proposed new rules that would make it easier for investment advisers and regulated funds to hold cryptocurrencies on behalf of clients.

The U.S. Securities and Exchange Commission has proposed new rules that would make it easier for investment advisers and regulated funds to hold cryptocurrencies on behalf of clients, as U.S. regulators push ahead with writing crypto rules after a sweeping legislation stalled in Congress.

The proposal, announced Thursday stateside, would establish a tailored framework governing how registered investment advisers, investment companies and business development companies hold custody of crypto assets.

The changes are aimed at modernizing decades-old custody requirements and removing regulatory barriers that the SEC says have limited advisers’ ability to offer crypto-related investments.

Under the proposed rules, crypto assets could be held in self-custody under “certain circumstances,” while state trust companies could also serve as custodians for crypto assets belonging to clients and regulated funds.

The changes could also give regulated funds greater scope to offer investors crypto-related investment strategies, according to the SEC.

SEC Chairman Paul Atkins said existing regulations had failed to keep pace with the rapid expansion of digital assets, which have grown into a multi-trillion-dollar market.

“Today’s proposal would provide a clear regulatory framework for the custody of crypto assets, giving investment advisers and funds a compliant pathway where none existed before,” Atkins said.

The proposal comes as U.S. regulators push ahead with building out a crypto rulebook under their existing authority after the Clarity Act, a sweeping crypto market structure bill, stalled in the Senate in September.

That marks another step in the SEC’s broader effort to rewrite the U.S. regulatory framework for digital assets under Atkins, and will be open for public comment for 60 days after it is published in the Federal Register.

With broader crypto legislation stalling in Congress, regulators are exerting their existing powers to address individual parts of the market, said Jeff Ko, chief analyst at blockchain infrastructure service provider ViaBTC.

“What we’re increasingly seeing is the SEC using the authority it already has to solve individual bottlenecks one by one, issuance, tokenization, trading exemptions and now custody,” he told CNBC via email.

The regulatory push also comes as crypto markets show signs of renewed momentum following a volatile start to the year. Bitcoin has rebounded over 40% from its July low, as improving risk appetite have helped revive demand for digital assets.

The recovery follows a prolonged downturn from late 2025 into the first half of 2026.
