Suggested March 2024 Neptune’s Bumpy Childhood Could Reveal Our Solar System’s Missing Planets

The modern solar system spins serenely, the planets locked in seemingly eternal circles around the sun. But it wasn’t always so. This tranquility appears to have emerged only after a gladiatorial period of planetary clashes—one in which titans ricocheted off each other, perhaps ejecting at least one rival sibling from the cosmic arena altogether.

Researchers have spent years scouring the solar system for clues of how that comparatively chaotic epoch might have played out. In a modest cluster of far-off rocks, David Nesvorny, a planetary scientist at the Southwest Research Institute, has found a figurative blood spatter suggestive of one particular conflict: a tussle between Neptune and an unknown planet that saw Neptune emerge victorious. His analysis, which appeared in late December in a not-yet-peer reviewed publication, adds further support to the notion that the solar system was once home to more than its current cadre of worlds.

To get this cohort of distant objects to pop out when you run the simulations, says Nathan Kaib, a planetary scientist at the University of Oklahoma who was not involved in the research, it seems like “you really need a planet to scatter [Neptune] off of.” That means, in theory, at least one extra planet may have been whizzing around the sun in eons past, knocking Neptune for a loop.

One way researchers can learn about events that took place more than four and a half billion years ago is by studying a current collection of ice balls known as the Kuiper Belt. Starting near Neptune’s orbit and extending outward from there, these frozen objects have been doing their own thing for eons, blind to most planetary drama.

The exception is the nearby Neptune, whose orbit has synched up with the orbits of many Kuiper Belt Objects (KBOs), including Pluto. This synchronization arises through subtle gravitational nudges from Neptune, which would have stopped those KBOs from forming in the first place. But since Pluto and its companions exist, researchers realized in the 80s and 90s, Neptune must have started out perhaps 10 to 20 percent closer to the sun and then slid outward later on (after Pluto and friends had already formed in peace).

But how did it relocate? One early idea was that it spiraled out smoothly as a result of regularly bumping into small objects, but a number of observations hinted at a more dramatic rearrangement: sometime in the solar system’s first millions of years, a number of near hits may have slingshotted planets into new positions on elliptical paths. Planetary scientists refer to this calamitous period euphemistically as an “instability.”

To get a better idea of what happened to Neptune during the instability, Nesvorny focused on one particular group of dozens of KBOs discovered over the last decade or so. Their orbits pass through the outskirts of the Kuiper Belt, but what really makes them special is how their paths tip roughly ten degrees out of the solar system’s flat disk—an indication that something pushed them out. “If you have certain orbit, it’s hard to tilt it differently,” Nesvorny says.

That something, according to new simulations from Nesvorny, is most likely a Neptune that slipped outward on an orbit with a just-so shape—one that falls somewhere between a perfect circle and a more severely squashed ellipse. Other scenarios just didn’t arrange this group of KBOs in the right place with the right slant.

To get Neptune moving in precisely that way would have taken a serious jolt, likely a close encounter with another planet of perhaps comparable mass. Previous studies, including work by Nesvorny, have suggested that the early solar system originally accommodated more giant planets than just Jupiter, Saturn, Uranus, and Neptune, a scenario that grows more likely if all the orbits went screwy for a while. “If you have an instability, you’re significantly more likely to lose planets than retain your original four,” Kaib says.

When Nesvorny runs hypothetical versions of the solar system in a simulation with a third ice giant (in addition to Uranus and Neptune), everything fits. If the mystery giant nearly collides with Neptune and Neptune’s orbit stretches as it moves out, giving the band of KBOs their distinctive 10 percent incline. The evidence is circumstantial, but suggestive.

“This is science,” he says. “You never know things for sure, but it’s compelling enough for me.”

Since Neptune survived the encounter, the additional ice giant was likely ejected from the solar system to wander the darkness of the Milky Way. However, if it didn’t receive quite enough of a kick to fly completely free of the sun’s gravity, it just might have come to rest perhaps 30 times farther from the sun than Neptune is today—exactly where some astronomers have predicted an unseen Planet Nine. The booted planet hangs around only around five percent of the time in simulations, Kaib says, but those are hardly unbeatable odds.

Better understanding the possible clashes between young planets, according to Nesvorny, is simply a matter of mapping the undisturbed outer reaches of the solar system in greater detail. This task will be a major goal for the upcoming Vera C. Rubin Observatory, which is expected to begin scientific operations in 2023.

“Because we have the Kuiper Belt,” he says, “it shouldn’t be that difficult to figure out what happened.”

Coming Solar Minimum Could Chill The Earth, New Forecast Predicts

Sunspots may be going into hibernation, a phenomenon unseen since the 17th century that could lead to cooler global temperatures, scientists said Tuesday. It’s not clear how rising temperatures from greenhouse gas emissions may offset global cooling, and scientists are still not totally sure how our star affects Earth’s climate, however. But a forthcoming period of solar quiet will help settle the questions.

Activity in the sun is building toward an expected peak sometime in 2013. Yet, despite a few notable solar flares, things are strangely calm. There are fewer sunspots in this cycle than expected, and they’re fainter than usual, for instance. The east-west plasma jet stream inside the sun is apparently missing, and the magnetic field’s pace of migration toward the poles is slowing down.

Based on these sets of findings, which were presented Tuesday at the annual meeting of the American Astronomical Society’s Solar Physics Division in Las Cruces, N.M., heliophysicists believe the current solar cycle, Cycle 24, could be the last one for a while. The sun might be entering a period of hibernation.

This was previously observed from 1645 to 1715, a period known as the Maunder Minimum in which there were practically no sunspots. The period coincided with part of the “Little Ice Age,” in which average temperatures in the northern hemisphere dropped by 2 to 4 degrees F.

Scientists said any temperature drops from a new prolonged solar minimum would be very small, however — likely not enough to offset warming from greenhouse gases. Recent 11-year solar cycles have changed global surface temperatures by 0.1 degrees C, said Judith Lean, a solar physicist with the US Naval Research Laboratory, in an AFP story.

Still, a prolonged solar sleep could impact space weather, space travel and even Earth communications. Less sunspot activity means less solar radiation, a slower solar wind and a weaker magnetic field, scientists said.

Magnetometers

These small magnetometers (alien cubes?) measure magnetic strength on Earth and in the atmosphere to determine how much of the sun’s magnetic energy has been transferred to Earth’s magnetosphere. In 2009, that energy reached record lows, partly because of the speed of the solar wind and the magnetic fields embedded within it.

Yet another paper on recent solar activity showed that the deep solar minimum back in 2008, when the solar disk was spotless, caused magnetic effects on Earth to drop. These magnetic effects cause the aurora, for one thing, and in extreme cases could cause power grid failures on Earth or induce dangerous currents in long pipelines, according to a NASA news release.

Given the period of recent quiet, Solar Cycle 25 could be delayed until 2023 or 2023 — or even longer than that, according to Frank Hill, associate director of the National Solar Observatory’s Solar Synoptic Network.

“If we are right, this could be the last solar maximum we’ll see for a few decades. That would affect everything from space exploration to Earth’s climate,” Hill said.

Businesses Could Make Solar Panels And Electric Cars As Commonplace As Home Computers

Energy officials from the world’s largest economies are meeting in San Francisco with the aim of accelerating the shift to zero-carbon power. Today, they announced a new campaign that will grease the wheels for businesses to buy into renewable energy.

This strategy has a history of working. Just as corporate buyers are driving growth in the clean energy market, they have previously led the adoption of other emerging technologies, from the fax machine to the personal computer. Here’s how businesses can help cutting edge machines make it from the laboratory to your living room.

Expanding networks

For most of its long history, the fax machine existed largely as a tool for newspaper publishers. It wasn’t until the 1980s that it became ubiquitous in corporate offices. As fax machines proliferated, each one became a little more valuable, able to connect to a broader network of devices. This, in turn, drove consumer sales.

Old timey fax machine European Patent Office

Fax machines offer an example of network effects. The larger a network becomes, the more incentive there is to join. Electric vehicles offer another example. Each new electric car increases the demand for charging stations. Each new charging station improves the utility and convenience of owning an electric car, which encourages other consumers to buy in. Businesses that purchase EVs or provide workplace charging stations can help expand networks.

“Network effects are critical for alternative fuels, including electric cars and offerings like Toyota’s new hydrogen-powered Mirai,” Mark Jacobsen, professor of economics at UC San Diego, said in an interview. Plus, he adds, “if business car fleets move to an alternative fuel, for example, this could help spread understanding about how the cars feel to drive, maintenance, and reliability.”

Economies of scale

Fifty years ago an IBM computer cost as much as $9 million, required a quarter-acre of air conditioned office space and needed a staff of 60 people to keep it running. Only governments and large businesses could profit from buying one. Through years of building room-sized machines, however, Big Blue developed the manufacturing muscle and engineering know-how needed to produce the IBM Personal Computer.

This is a story about economies of scale. As operations grow, the cost of each unit sold decreases. Clean energy is subject to the same effect. Solar companies are moving more panels, expanding output and improving manufacturing, feeding a virtuous circle of tumbling prices and booming sales. Businesses that buy photovoltaic panels are helping producers reach economies of scale.

Solar prices and installation Department of Energy

“We see businesses helping solar energy reach economies of scale,” Jessika Trancik, an MIT professor of energy studies, said in an interview. “For example, a growing number of businesses are building commercial-scale solar installations, and these installations have been able to capture economies of scale.”

Clean energy is ready to explode

New technologies follow a familiar pattern, lingering on the sidelines until they become cheap and useful enough to be widely adopted. Once the market is saturated, the rate of adoption levels off. This is called the “S curve.” It describes the spread of fax machines, personal computers and a host of other technologies.

The S Curve Davidmountain, via Wikimedia Commons

Today, clean energy is peering up the steep incline of the S curve, waiting for falling prices to spark rapid adoption. Last year, renewables accounted for a majority of new generating capacity worldwide. Global sales of electric cars grew by leaps and bounds. Businesses can nudge emerging technologies along by helping them reach the scale needed to further drive down costs and improve performance.

Corporations are embracing clean energy

Businesses are driving a lot of the growth in clean energy. That’s because emerging technologies offer a bigger upside to companies that can pay high up-front costs, purchase in bulk and reap the long-term benefits. Corporations can save big by buying solar or wind energy at a low fixed cost through large-scale power purchase agreements. This allows companies to guard against volatility in the fossil fuel market, to say nothing of the reputational perks.

“One main reason that consumer-facing businesses can benefit from going green is the goodwill and support of their customers: there is increasing demand for products and companies that are reducing pollution,” said Jacobsen. This cuts both ways. Just as businesses curry favor by buying into clean energy, they also show consumers that emerging technologies are economically viable.

“Businesses can adopt clean energy in ways that are clearly visible to their consumers and employees,” said Trancik, “In this way, they can play a unique and important role in helping to build awareness of the falling costs of several key clean energy technologies, such as solar energy and electric vehicles.”

Apple, Google, Microsoft, IKEA and even News Corp, parent company of Fox News, have made enormous investments in renewables. New generating capacity added by corporations has more than doubled every year since 2012, according to the Rocky Mountain Institute.

Corporate renewable energy deals Rocky Mountain Institute

As part of the new campaign, today Facebook pledged to getting 50 percent of its energy from clean sources by 2023. Wells Fargo committed to buying enough renewable energy to power 100 percent of its operations by 2023. Several other influential corporations laid out similar goals.

These corporate commitments will push renewables even further, spurring the growth of clean power. Before long, solar panels and electric cars could be just as commonplace as the personal computer.

6 Early Childhood Tips. . . From A 5Th Grade Teacher?

Last year, the seven-year itch hit me hard, and after being quoted many times saying, “I was made for first grade,” I decided that it was time for me to make a change and move up, way up to fifth grade. I thought my transition would be cut and dried, like how you end dinner and begin dessert — but as with a lot of other changes in life, it was much messier than that. Now, seven months later, I’m still finding myself stuck somewhere between the lower-grade and upper-grade worlds, with a savvy co-teacher and 25 eager ten-year-olds by my side.

With middle school on the horizon, fifth grade is high stakes, and while I’m enjoying myself, I’m not sure how long I’ll stay. But there’s one thing I know for sure — this experience has taught me more about early childhood education than another year in first grade ever could have. Teaching some of the same kids in the same school has created the ideal conditions to constantly wonder, “What did I do (or what should have I done) when teaching first grade to prepare these kids for this stage?”

Over the past seven months, here are six things I’ve learned that early childhood educators should do every day:

1. Be clever with your compliments.

Some of the same students who were once saying, “I’m bad at math” are still saying, “I’m bad at math.” Statements like these are signs of a fixed mindset. They trick you into believing you are either “good” or “bad,” and that growth isn’t possible — which is why it’s important to tell them exactly what they are good at in each subject area, starting in the primary grades. Then they will understand that they have strengths along with their areas for growth, and by the time they get to fifth grade, hopefully they won’t be saying, “I’m bad at math” any more.

2. Teach into being an ally for everyone.

Recently Danny hasn’t wanted to come to school. He puts is head down for most of the day. Last week, he walked out of the classroom without permission — twice. I’ve had lots of conversations with Danny, and in each one, he reveals that nobody likes him and he’d rather stay at home. My co-teacher and I pulled the class together, presented them with this problem, and asked, “What should we do?” It was Maria who took out her soapbox and said, “We need to start treating him with more respect. It’s not that you have to be best friends with everyone. It’s that you have to support everyone, because learning is hard.” And there you have it. Maria said it best.

3. Talk about diversity.

In my class, we talk at length about Eric Gardener, why girls might not be playing football at recess, and what it means to be middle class. Research shows that fifth grade students need to talk about these things, but we must prepare them to do so by starting this conversation in kindergarten. My students are prepared — they came to me that way, because every teacher before me has taken the time to bring up topics of diversity in strategic, logical, developmentally appropriate, thorough ways. In kindergarten, they study skin color. In first grade, they define diversity. In second grade, they analyze who has access. . . and so on.

4. Trash your assumptions about their families.

In first grade, Felipe was angry about a lot of things including his parents’ divorce. Fast forward to fifth grade, Felipe is still angry (although less so) about a lot of things. Starting on day one, we decided to address this situation differently. This time, we included both Mom and Dad in our conversations about Felipe. In first grade, we assumed that living with Mom meant Dad had less insight to offer and less of an impact on Felipe’s daily life. Wrong! Now, we talk to both Mom and Dad, and while Felipe is still angry, he feels more secure in my class today.

5. Keep your eyes on the prize: the big ideas.

I’m both in love with and overwhelmed by teaching history! Luckily, John, the fifth grade teacher across the hall, is nothing short of an expert and reminds me every time we meet that it’s less about the details and more about the big ideas. For example, while it’s not important to learn each and every Jim Crow law, it’s important to know how those laws affected the daily lives of people in the South and how they affect our lives today. We only have ten months with our students, so what exactly do we want them to learn?

6. Celebrate hard.

The saying “work hard, party hard” is legit. In fifth grade, we’re always finding reasons to celebrate because the expectations feel so high — but I’m starting to realize that they always were. My first grade class learned how to read! They did more mental math in ten months than my grandmother does in ten years. In September, they told stories in pictures, and by June, they were telling stories with words on lined pages. And we forgot to party. What a bummer.

I encourage all of you to make big changes, to stretch yourself far beyond what you thought you were capable of doing, to leap out of your comfort zone, from early childhood to upper grades — for the sake of your students, yes, but also for the sake of learning more about this profession we love so much. If you have done that, well, please tell us, what did you learn? How did it go?
