The Spring Equinox Is Coming Soon: When and What You Need to Know
After a long, cold winter, the vernal equinox heralds the arrival of spring in the Northern Hemisphere. But have you heard the myth about balancing an egg on its end?
Despite the long winter, I can feel how close spring is. Here in California, blossoms are blossoming, trees are budding and the orange poppies are starting to pop. The vernal equinox is coming soon, signaling the astronomical start of spring in the Northern Hemisphere.
Though equinoxes might not get the same attention as solstices, they’re a lovely way to observe the seasons shifting. Let’s get to know the vernal equinox, what it is and why it happens.
What is the spring equinox?
You’ve no doubt noticed the lengthening of daylight as winter winds down (especially with daylight saving coming this weekend). The vernal equinox marks the tipping point into longer days.Â
The word “equinox” comes from the Latin words for equal and night. Daylight and night are roughly equal during the equinox. We experience two each year — the vernal equinox in the spring and the autumnal equinox in the fall. The word “vernal” traces to Latin and references spring.Â
The Earth spins on an axis (think of it like a line running from pole to pole) with a 23.5-degree tilt. Some parts of the planet get more direct sunlight than others. That’s how we get our seasons, and how it can be summer in the Northern Hemisphere while it’s winter in the Southern Hemisphere.
“The spring equinox is when the Northern Hemisphere transitions from being pointed away from the sun (during winter) to being pointed toward the sun (during summer),” says Emily Rice, associate professor of astrophysics at the Macaulay Honors College of the City University of New York. “The tilt is lined up with Earth’s orbit for just a moment.” That’s when we get nearly equal amounts of daylight and night.
When does the vernal equinox happen?
The spring equinox has a specific time, occurring at 10:46 a.m. ET/7:46 a.m. PT, on Friday, March 20.
How are equinoxes different from solstices?
Solstices are the extremes of days and nights. The summer solstice is the longest day, and the winter solstice is the shortest. In 2026, the summer solstice for the Northern Hemisphere occurs on June 21, and the winter solstice happens on Dec. 21.
Solstices get more love than equinoxes.Â
“The extremes are easier to mark and to visualize than the inflection points, which are more subtle changes, so the solstices get all the attention,” says Rice. All of them are related to Earth’s tilt and the sun, so think of solstices and equinoxes as siblings that each have their own seasonal connection.
What the equinox looks like from space
It can be challenging to visualize the Earth’s tilt and what happens during an equinox from down on the ground, so NASA put together a video showing the Earth as seen by a satellite.
It tracks our planet through its seasons. Watch how night and daylight shift over time.
How to celebrate the spring equinox
Perhaps you’ve heard that the only day you can balance a raw egg on its end is on the equinox. This legend might be accompanied by some vague discussion points about Earth’s gravity and alignment, and the sun.Â
One of Rice’s annual equinox duties is debunking the egg-balancing myth.Â
“Astronomers are usually on the internet telling people that no, they can’t actually balance an egg on its end only on an equinox,” she said. You can go ahead and try it, but be sure to also test it out on a day that’s not the equinox. I pulled it off on Feb. 27, in case you’re wondering.Â
An equinox is a subtle phenomenon. There are no showy celestial events to mark the day. Don’t let that deter you. The vernal equinox is what you make of it.Â
“Considering that the Earth’s orbit doesn’t have a beginning or an end, a year could really be started any time, and the equinox is more astronomically meaningful than Jan. 1,” says Rice.
You can come up with your own way to celebrate the occasion. Tell your friends and co-workers it’s the start of astronomical spring. Plant some seeds. Clean your house. Spend time outside. Make plans for spring break. And take a moment to toast the sun, the Earth’s tilt and our place in space that brings us the vernal equinox.

China indicates rare earths will keep flowing to EU, regardless of U.S. trade deal expiration
European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing last week.
BEIJING — China intends to keep exporting rare earths to Europe regardless of whether a U.S. trade deal with Beijing gets extended past January.
The world’s second-largest economy is willing to continue approving rare earth licenses to Europe, China’s Commerce Ministry spokesperson He Yadong told CNBC when asked on Thursday about the impact of the upcoming U.S. deadline.
Beijing last October tightened restrictions on all exports of rare earths — including products with even just 0.1% of China-sourced rare earths. The move followed a new U.S. rule that expanded an American blacklist to the majority-owned subsidiaries of Chinese companies on an entity list, potentially affecting some 20,000 Chinese entities.
However, both the U.S. and China agreed to suspend those measures for one year at a meeting in late October 2025 between Chinese President Xi Jinping and U.S. President Donald Trump. Ahead of the leaders’ latest summit last month, U.S. Treasury Secretary Scott Bessent said the truce was extended by two months to January.
Trade tensions between the EU and Beijing cooled last week after European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing. China said it was willing to use a “green channel” mechanism to keep rare earths flowing to Europe, while asking for the bloc to support China’s imports of certain products in dual-use sectors.
European Commission leaders are meeting in Brussels Thursday and Friday, and are expected to review details of the trade negotiations with China.

Analysis: Why a $2 trillion deficit and 5% Treasury yields are becoming America’s biggest economic challenge
Treasury yields above 5% are raising borrowing costs for households and the federal government, highlighting the challenge of financing $2 trillion deficits.
Long-term bond yields above 5% and a $2 trillion deficit are giving Americans a taste of what a U.S. debt crisis would be like. A true emergency would hurt much more, and isn’t baked in. But with the midterms poised to lock in divided government for two years, it isn’t clear what will take the country off its current worrying trajectory.
Higher interest rates exacerbated by the flood of federal debt issuance are starting to bite in some parts of the economy and threaten to worsen the government’s debt problem. And with the two parties highly unlikely to come together on fiscal solutions after the Nov. 3 midterms, any fixes are years off in the future.
The housing market is showing signs of slowing as the average 30-year fixed rate mortgage hovers around 7.5%. Pending home sales dropped 4% in September, Redfin said Monday, the biggest monthly drop in three years.
Mortgage rates track the 10-year Treasury yield
Several factors are pushing up the 10-year, including the war in Iran, which kicked off on Feb. 28 and precipitated the rise in long-term yields. Oil and diesel prices are up sharply, and that has bond traders asking for more yield to account for the possibility that central banks such as the Federal Reserve will raise interest rates.
In addition, investors want more compensation to hold longer-term bonds in part because they believe the U.S. government will continue to flood the market with them. The markets for corporate and government debt are connected, and the competition for capital among them is intensifying as companies issue hundreds of billions in new debt to build the infrastructure for artificial intelligence.
Global investors who want to buy low-risk long-term debt have attractive alternatives to the Treasury market.
If the U.S. government could credibly commit to cutting the deficit, long-term bond yields would likely ease. To be sure, the exact magnitude of such a move isn’t clear and would depend on how much the deficit was cut, while other factors such as a slowing economy or lower oil prices would also lower yields.
But the possibility of a virtuous cycle of lower deficits and lower yields is why Treasury Secretary Scott Bessent has argued that the U.S. ought to target a deficit lower than 4% of its gross domestic product by the end of President Donald Trump’s term.
There is almost no way the U.S. will hit that target. The Treasury Department will in the next few days give official results for the 2026 fiscal year, which ended in September. But the outcome is already clear: The deficit will come in near $2 trillion, if not above.
That is likely to put the deficit in the range of 6.0-6.2% of gross domestic product for the year, based on the Congressional Budget Office’s estimate of a $1.993 trillion deficit and a projection of third quarter GDP.
Higher rates make debt reduction tougher. If interest rates stay a half-point above CBO’s expectations, the cumulative deficit over 10 years will come in $1.9 trillion higher, the agency estimates. If rates overshoot by 1.5 points, that adds $6 trillion in deficits.
CBO expects the 10-year Treasury to average 4.3% over that period, compared to 5.3% today. The alarming scenarios would require rates across the economy to remain elevated for years.
“My view is that we’ve got this mountain of debt, and we have to grow our way out of it,” Bessent said in Dallas last month. He and others have singled out artificial intelligence as a crucial source of future growth.
AI could help but can’t fix the problem entirely. It would take a decade of 7.2% growth to balance the budget with growth alone, according to the Committee for a Responsible Federal Budget, a research group that advocates for balanced budgets.
GDP growth was recently revised up for the second quarter from 1.5% to 2.2% at an annualized rate. The acceleration that quickly would get us to 7.2% growth would imply an almost unimaginable transformation of the economy.
Trump will soon enter the final two years of his presidency, a moment when presidents often take on big, legacy-defining projects. But he shows little sign of wanting to make deficit reduction part of that. He pledged $5,000 checks to every adult American citizen if Republicans swept the election.
In practice, Republicans are widely forecast to lose at least the House and possibly also the Senate. Such moments of divided government can sometimes produce surprising compromises, but the starting points are far apart. Rep. Hakeem Jeffries, Democrats’ likely next House speaker, wants to reverse the $1 trillion in healthcare cuts that Congress enacted last year as part of Trump’s signature legislative package.
And that’s leaving aside the deep animosity between the parties.
The overall U.S. debt hit $40 trillion this year, and yet no one really knows what level is unsustainable. A full-on debt crisis likely remains much farther out in the future. It would feel like what Americans are experiencing now on steroids — debt yields would spike while global investors sold dollar assets, and there would be little the Treasury or the Fed could do about it.
For now, though higher yields are also attracting investors to U.S. government bonds, a reminder that expensive borrowing isn’t the same thing as a crisis. But the bottom line is that economics alone can’t solve the problem. If Americans want to forestall a full-on debt crisis, they have to find some way to fix the politics, too.

Key Details on Starshield, SpaceX’s Defense-Oriented Starlink Network
Questions over control of SpaceX’s Starshield military satellite network have intensified after Ukraine reported sudden restrictions that disrupted defenses. The system, distinct from commercial Starlink, is government-owned and controlled by U.S. authorities.
Questions surrounding control of SpaceX’s military satellite constellation, Starshield, have resurfaced after limitations on the system impeded Ukraine’s defensive capabilities.
Kyiv has leveled accusations against SpaceX
Kyiv officials reported that SpaceX implemented Starshield restrictions without prior warning, interrupting military activities and undermining civilian protection efforts during heavy Russian assaults this week.
Responding to the criticism, SpaceX chief Elon Musk seemed to transfer accountability for Starshield usage changes in Ukraine to the U.S. government and President Donald Trump. Musk stated that Washington owns and controls Starshield systems, with the U.S. military and ultimately the president setting any usage boundaries. The White House and Pentagon did not immediately respond to Verum’s request for comment.
Here’s an overview of Starshield and its distinctions from Starlink.
What is Starshield and how does it function?
Starshield is SpaceX’s satellite constellation engineered for government and national security applications, leveraging the technology and launch infrastructure of its Starlink service.
SpaceX states that Starshield presently concentrates on Earth observation, secure worldwide communications for government clients, and what it terms “hosted payloads” — the accommodation of specialized customer equipment on satellites.
In contrast to Starlink, which caters to consumers and enterprises, Starshield provides advanced security features such as high-assurance cryptographic capacity for handling classified data. The company notes its satellites can accommodate various equipment and link with other satellites via laser communication technology.
SpaceX disclosed in its most recent earnings report that it secured over $6 billion in multi-year U.S. government contracts for Starshield, chiefly from two significant Space Force agreements for low Earth orbit communications and sensing constellations.
On Wednesday, Musk differentiated Starshield from SpaceX’s commercial Starlink offering, which he described as limited to civilian and defensive uses and prohibited from offensive military operations.
How does Starshield contrast with Starlink?
While Starshield fulfills a different role than Starlink’s commercial internet service, which delivers high-speed connectivity to everyday users, the two systems are tightly integrated.
Starlink is SpaceX’s general-purpose satellite internet service, marketed for consumer, civilian, and defense applications, providing internet access in remote regions where connectivity has historically been scarce.
Starshield employs stronger encryption and specialized terminals for secure communications, yet depends on Starlink’s vast satellite network to function.
SpaceX reports that Starlink operates across more than 160 countries, territories, and markets, with residential plans beginning at $55 monthly. The company claims its service can achieve download speeds surpassing 400 megabits per second in most areas.
