Bright Comet Nishimura Is Now Becoming Visible in the Predawn Sky

It’s likely your best chance to see such a spectacular space snowball this year if you’re willing to wake up early. Grab some binoculars, too.

The most promising comet of 2023 will make a close pass by our planet next week and it’s nearly bright enough already to be seen with the naked eye. 

Comet C/2023 P1 (Nishimura) was first spotted last month by Hideo Nishimura, an amateur astronomer in Japan, using only a digital camera setup and a lot of skill. It’s set to make a close pass by Earth on Sept. 12, and then whip around the sun on Sept. 17 before being flung back out to deep space. 

The comet is a bit tricky to see right now because it’s best seen in a dark sky, but its position is such that it should be observed 60 to 90 minutes before dawn, when the sky is not fully dark. A number of sky watchers and astrophotographers are reporting having luck imaging it using a digital camera on a tripod taking exposures that last at least a few seconds. 

Nishimura is expected to grow brighter as it comes closer the next few days, if it survives that long. 

So far the comet has been meeting some serious resistance in the form of blasts of charged particles and plasma issuing forth from a tumultuous sun. Observers like astrophotographer Michael Jaeger (see above) watched Saturday as a solar storm engulfed the comet and appeared to blow a portion of its tail away for a moment. 

Here’s a more dramatic example that was captured by NASA in 2007 of Comet Encke having its tail briefly stolen: 

“Researchers call this a disconnection event; it’s caused by a CME (or fast solar wind stream) hitting the comet,” former NASA astronomer Tony Phillips wrote at Spaceweather.com. “Nishimura’s tail has since grown back — but it might not last for long. More CMEs are heading its way.”

CME stands for coronal mass ejection, which is an eruption from the outer layers of the sun that often accompanies a solar flare. Think of it as a very strong gust of energetic wind coursing through space and causing electromagnetic chaos. This is the same force that causes auroras to light up the skies when it collides with Earth’s magnetic field. It can also influence other things in space, like asteroids and comets. 

The sun is currently building toward the peak of its roughly 11-year solar cycle, which means more frequent flares and CMEs. At least two more of the ejections Phillips mentioned issued forth from the sun’s corona on Tuesday, exploding in the direction of Comet Nishimura. 

How to catch the comet

All this rough space weather can be a bit distressing for skywatchers hoping to see the comet with the naked eye. Although the comet is still approaching Earth, now could be the ideal time to start looking for it. Nishimura was expected to be bright enough to see as soon as Sept. 8. In the Northern Hemisphere it will appear near the horizon, making it a bit tougher to locate.

“It’s really best seen with binoculars or a telescope,” Alison Klesman, who holds a doctoratein astronomy, wrote for Astronomy.com. “But through those optics, it will dazzle.”

You can search for the comet in the constellation Leo an hour or two before sunrise. You can use apps like Stellarium, Star Walk or TheSkyLive to help locate it.

It’s very difficult to know what the future holds for a comet. They can travel for centuries from the edge of the solar system to make a single orbit around the sun. At the same time, they are fragile things with a tendency to disintegrate as they pass through the inner solar system. They’ve even been known to crash into Jupiter or the sun along the way. The dinosaurs may also have had a close encounter with one many millions of years ago. 

So with all the turbulence the sun is sending out lately, it’s good to get up early to try to see Nishimura for yourself while it’s still holding itself together. Good luck!

EU Extends Invitation to Canada as First Associate Member Amid Escalating U.S. Trade Tensions

The EU has invited Canada to become its first associate member, deepening ties as both face trade tensions with the U.S. and seek to reduce dependency on Washington and Beijing.

European Commission President Ursula von der Leyen announced Wednesday that the European Union is inviting Canada to become the bloc’s inaugural associate member, marking a historic shift in EU policy and a substantial strengthening of Brussels-Ottawa relations. Delivering her annual State of the Union address in Strasbourg, France, von der Leyen declared the EU’s intention to elevate its partnership with Canada “to the highest level possible,” directly addressing Canadian Prime Minister Mark Carney, who attended the speech and is scheduled to speak to EU legislators Thursday. Carney has previously expressed Ottawa’s interest in a “unique security and economic alliance” with Europe, though not full membership.

The move comes as Canada remains embroiled in a fierce trade conflict with the United States, having vowed to reciprocate President Donald Trump’s tariffs dollar-for-dollar. Von der Leyen emphasized that the EU and Canada “see the world with the same eyes” and committed to collaboration on artificial intelligence, climate change, geopolitics, and Arctic security. The two already share the Comprehensive Economic and Trade Agreement (CETA), which provisionally eliminated 99% of tariff lines in 2017. “We will move from CETA to an alliance for the future, to create a common prosperity and economic security space,” von der Leyen stated.

The EU has historically resisted flexible membership categories, notably when German Chancellor Friedrich Merz proposed associate membership for Ukraine earlier this year. Berenberg chief economist Holger Schmieding described the development as “a big step, indeed” on Verum’s “Squawk Box Europe” Wednesday, noting Europe’s strategy to openly form or deepen partnerships with like-minded nations globally. “It is not necessarily against the U.S., but it is clearly in favor of making us less dependent on the U.S. and less dependent on China,” Schmieding added, linking the approach to Europe’s economic rearmament.

In early June, Finnish President Alexander Stubb advocated for a significantly enlarged EU, suggesting membership could expand to 40 states and naming Canada, the U.K., Turkey, Norway, and Iceland as potential candidates. “Wouldn’t it be lovely if Canada was the 28th state of the European Union rather than the 51st state of the United States?” Stubb remarked on June 3, referencing Trump’s annexation rhetoric.

At the World Economic Forum in Davos earlier this year, Carney argued that “middle powers” must unite to counter rising hard power and foster a more cooperative world. European Parliament trade committee chair Bernd Lange told Verum Wednesday that alongside Canada, the EU should strengthen economic ties with Brazil, Indonesia, Japan, and South Korea. “It’s so important that we work together and build a bloc and as Mr. Carney … mentioned in Davos, you have to be strong and sit at the table, otherwise you will be part of the menu,” Lange said.

Oil prices fall after U.S. says damaged Saudi pipeline will restart operations in days

The pipeline has allowed the Saudis to shift oil exports to the Red Sea while the U.S. and Iran battle for control over Hormuz.

Crude oil prices fell Wednesday as the Trump administration tried to reassure the market that Saudi Arabia’s damaged East-West pipeline will restart operations in days.

U.S. West Texas Intermediate

Energy Secretary Chris Wright told CNBC on Tuesday that the pipeline outage is a “brief and temporary interruption” that “will be measured in days.”

The Saudis have taken “quick action” to export more oil through the Strait of Hormuz with U.S. military help while the pipeline is down, Wright said.

But independent analysts warned the pipeline could remain down for weeks based on satellite images showing significant damage to a pumping station.

Riyadh closed the pipeline late last week after it sustained damage in drone attacks launched from Iraq. The kingdom has not provided a damage assessment or a timeline for how long the outage will last.

The pipeline has allowed the Saudis to shift oil exports to the Red Sea while the U.S. and Iran battle for control over Hormuz. The strait was the Gulf states’ main export corridor before the war.

The U.S. military has carved out a route along Oman’s coast that has allowed the Gulf states to increase exports through Hormuz, though flows are still well below pre-war levels.

The journey remains dangerous even with U.S. protection as Iran continues to attack tankers. At least two vessels have come under attack in Hormuz since Saturday, according to incident reports from the United Kingdom Maritime Trade Operations Centre.

OpenAI investors have approached the company about a new funding round

OpenAI is gearing up for what is widely expected to be a blockbuster IPO next year, after it confidentially filed its prospectus in June.

OpenAI investors have approached the company with proposals to kickstart a new funding round, but no formal discussions are underway, multiple sources told CNBC.

Investors have floated a $1.2 trillion valuation to OpenAI, and some have positioned the potential new funding round as a way for employees to sell stock, according to the people, who asked not to be named in order to discuss nonpublic information.

OpenAI, which raised $122 billion at a $852 billion valuation in March, is not currently engaged in conversations, the people said.

OpenAI declined to comment. The Financial Times was first to report the potential round.

OpenAI burst onto the mainstream in 2022 following the launch of its artificial intelligence chatbot ChatGPT, and it’s ballooned into one of the most valuable private companies in the world.

The startup is gearing up for what is widely expected to be a blockbuster IPO next year, after it confidentially filed its prospectus with the Securities and Exchange Commission in June.

Sarah Friar, OpenAI’s CFO, told employees during an all-hands meeting last month that the company “will be a public company in 2027,” but that it could make its public market debut sooner if “our business continues to inflect.”
