The Stray Planet That Escaped Our Solar System – Worldatlas.com

Published

 on


As early as the 1840s, the existence of a planet that affects the orbits of Uranus and Neptune was theorized. After the discovery of Pluto in the early 20th century, astronomers initially believed it to be the long-sought ninth planet. However, this theory was later revised when it became clear that Pluto’s gravitational pull was too weak to account for the observed perturbations in the orbits of Uranus and Neptune.

In January 2015, Caltech astronomers revealed research indicating the existence of a large planet with an elongated orbit in the outer solar system. However, this remains a mathematical model, and no such planet has been directly observed.

Historical Context

Pluto was kicked out of the planet category in 2006. 

Upon discovering our most distant planet, Neptune, in 1846, scientists have been looking for this so-called Planet X. The theory was developed over the decades until it finally reached a much more coherent form at the beginning of the 20th century.

The theory suggests that since the orbital patterns of both Neptune and Uranus are so bizarre and unusual, this could point to another sizeable unseen planet that could be causing this odd behavior. American astronomer Clyde Tombaugh followed this theory and eventually discovered Pluto in 1930. 

It was quickly determined that Pluto was not the culprit, causing Uranus and Neptune’s orbits to be out of wack. Pluto was much too small to have such a profound impact on either planet. Both of which are much larger than Pluto itself. Whatever was causing this was still yet to be seen by humans. 

Scientific Evidence and Research

Very little is still known about our early solar system. 

Since the popularization of the Big Bang Theory in the previous century, countless tests and research have been done to help give scientists a better understanding of what our early universe might have looked like. Some of the details still need to be clarified, but scientists can agree that the orbits of giant planets like Jupiter, Saturn, Neptune, and Uranus could have been unstable. In theory, this Planet X could have had a somewhat regular orbit until it was thrown off course and sent out into the furthest reaches of our solar system. 

In some simulations that aim to represent the formation of our planets, this instability occurred 90% of the time. The orbits in our solar systems have been stable for billions of years at this point and only change slightly. So, a planet may exist out there that was knocked off course long ago and now has an incredibly long orbit around the sun. 

Going off what it would theoretically take to impact the orbit of Nepute and Uranus, experts think that Planet X could be ten times larger than Earth and take between 10,000 – 20,000 years to orbit the Sun entirely. At its closest point to the Sun, Planet X would still be seven times further away than Neptune’s. 

Exhiled Planet Theory

If Planet X is accurate, it likely resembles something like Neptune or Uranus. 

Planet X is assumed to be something that scientists call Super-Earths or Mini-Neptunes. Made up mostly of gas and rock, these planets appear to be incredibly common in the Milky Way Galaxy and have been spotted numerous times in other far-off solar systems.

Neptune and Uranus would fit into this category. Considering that both distant planets had a very violent and chaotic early history, there is certainly a chance that a third similar planet could have been knocked off course after colliding with other worlds. 

Some scientists think that if there were a 9th planet that was formed like this, it would have been completely thrown out of our solar system, but there are still counters to this point. Others suggest that the sheer amount of dust and gas that would have been present in the early solar system could have slowed it down enough to keep it just within the gravitational pull of our Sun. 

Implications on Solar System Dynamics

The study of Planet X has led to some changes in how we think of our solar system. 

The possibility of Planet X’s existence has led to some changes in how experts now think about the dynamics of our solar system. If Planet X is real, likely, the orbits of planets and other objects in our solar system are much more unpredictable and chaotic than previously thought.

The early details of our solar system’s evolution sometimes need to be more apparent. If humans can find and study this mysterious planet that may or may not exist, we could paint a clearer picture of how it was formed and how our solar system was formed. 

Another interesting theory about Planet X claims that its origins might not have formed from our solar system but originated from an alien system and was then thrust into the gravitational pull of our sun due to some unknown event. 

Future Explorations

As technology improves, there needs to be more telling of what progress could be made on this topic

Due to the sheer distance of where this supposed planet is supposed to be located, it has yet to be possible to obtain any clear evidence of its existence. Cosmologists, mathematicians, and astronomers have been stuck using simulations and mathematical theories. That being said, improvements are being made. 

With the increase in computer technology in the last few decades, more accurate simulations have been made, each painting a straightforward painting of how Planet X might have been formed and where it might be located. 

If trends continue, there might be a good chance this mystery will be on its way to being solved sometime shortly. 

Conclusion

Once thought to be nothing more than a far-flung hypothetical, the reality of a 9th planet existing somewhere within our solar system is becoming more plausible with each passing year. As technology improves each generation, there is a much higher chance that the scientific community will finally get to the bottom of what has been the source of endless late-night discussions and wacky conspiracy theories once and for all. 

The study of Planet X is not just the hunt of some rouge planet that was once a part of our young system billions of years ago, but it also reveals so much of how Earth and the other known planets in our solar system came into being.

Here’s how Helene and other storms dumped a whopping 40 trillion gallons of rain on the South

Published

 on

 

More than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it — an unheard of amount of water that has stunned experts.

That’s enough to fill the Dallas Cowboys’ stadium 51,000 times, or Lake Tahoe just once. If it was concentrated just on the state of North Carolina that much water would be 3.5 feet deep (more than 1 meter). It’s enough to fill more than 60 million Olympic-size swimming pools.

“That’s an astronomical amount of precipitation,” said Ed Clark, head of the National Oceanic and Atmospheric Administration’s National Water Center in Tuscaloosa, Alabama. “I have not seen something in my 25 years of working at the weather service that is this geographically large of an extent and the sheer volume of water that fell from the sky.”

The flood damage from the rain is apocalyptic, meteorologists said. More than 100 people are dead, according to officials.

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just Georgia, Tennessee, the Carolinas and Florida from Hurricane Helene.

Clark did the calculations independently and said the 40 trillion gallon figure (151 trillion liters) is about right and, if anything, conservative. Maue said maybe 1 to 2 trillion more gallons of rain had fallen, much if it in Virginia, since his calculations.

Clark, who spends much of his work on issues of shrinking western water supplies, said to put the amount of rain in perspective, it’s more than twice the combined amount of water stored by two key Colorado River basin reservoirs: Lake Powell and Lake Mead.

Several meteorologists said this was a combination of two, maybe three storm systems. Before Helene struck, rain had fallen heavily for days because a low pressure system had “cut off” from the jet stream — which moves weather systems along west to east — and stalled over the Southeast. That funneled plenty of warm water from the Gulf of Mexico. And a storm that fell just short of named status parked along North Carolina’s Atlantic coast, dumping as much as 20 inches of rain, said North Carolina state climatologist Kathie Dello.

Then add Helene, one of the largest storms in the last couple decades and one that held plenty of rain because it was young and moved fast before it hit the Appalachians, said University of Albany hurricane expert Kristen Corbosiero.

“It was not just a perfect storm, but it was a combination of multiple storms that that led to the enormous amount of rain,” Maue said. “That collected at high elevation, we’re talking 3,000 to 6000 feet. And when you drop trillions of gallons on a mountain, that has to go down.”

The fact that these storms hit the mountains made everything worse, and not just because of runoff. The interaction between the mountains and the storm systems wrings more moisture out of the air, Clark, Maue and Corbosiero said.

North Carolina weather officials said their top measurement total was 31.33 inches in the tiny town of Busick. Mount Mitchell also got more than 2 feet of rainfall.

Before 2017’s Hurricane Harvey, “I said to our colleagues, you know, I never thought in my career that we would measure rainfall in feet,” Clark said. “And after Harvey, Florence, the more isolated events in eastern Kentucky, portions of South Dakota. We’re seeing events year in and year out where we are measuring rainfall in feet.”

Storms are getting wetter as the climate change s, said Corbosiero and Dello. A basic law of physics says the air holds nearly 4% more moisture for every degree Fahrenheit warmer (7% for every degree Celsius) and the world has warmed more than 2 degrees (1.2 degrees Celsius) since pre-industrial times.

Corbosiero said meteorologists are vigorously debating how much of Helene is due to worsening climate change and how much is random.

For Dello, the “fingerprints of climate change” were clear.

“We’ve seen tropical storm impacts in western North Carolina. But these storms are wetter and these storms are warmer. And there would have been a time when a tropical storm would have been heading toward North Carolina and would have caused some rain and some damage, but not apocalyptic destruction. ”

‘Big Sam’: Paleontologists unearth giant skull of Pachyrhinosaurus in Alberta

Published

 on

 

It’s a dinosaur that roamed Alberta’s badlands more than 70 million years ago, sporting a big, bumpy, bony head the size of a baby elephant.

On Wednesday, paleontologists near Grande Prairie pulled its 272-kilogram skull from the ground.

They call it “Big Sam.”

The adult Pachyrhinosaurus is the second plant-eating dinosaur to be unearthed from a dense bonebed belonging to a herd that died together on the edge of a valley that now sits 450 kilometres northwest of Edmonton.

It didn’t die alone.

“We have hundreds of juvenile bones in the bonebed, so we know that there are many babies and some adults among all of the big adults,” Emily Bamforth, a paleontologist with the nearby Philip J. Currie Dinosaur Museum, said in an interview on the way to the dig site.

She described the horned Pachyrhinosaurus as “the smaller, older cousin of the triceratops.”

“This species of dinosaur is endemic to the Grand Prairie area, so it’s found here and nowhere else in the world. They are … kind of about the size of an Indian elephant and a rhino,” she added.

The head alone, she said, is about the size of a baby elephant.

The discovery was a long time coming.

The bonebed was first discovered by a high school teacher out for a walk about 50 years ago. It took the teacher a decade to get anyone from southern Alberta to come to take a look.

“At the time, sort of in the ’70s and ’80s, paleontology in northern Alberta was virtually unknown,” said Bamforth.

When paleontogists eventually got to the site, Bamforth said, they learned “it’s actually one of the densest dinosaur bonebeds in North America.”

“It contains about 100 to 300 bones per square metre,” she said.

Paleontologists have been at the site sporadically ever since, combing through bones belonging to turtles, dinosaurs and lizards. Sixteen years ago, they discovered a large skull of an approximately 30-year-old Pachyrhinosaurus, which is now at the museum.

About a year ago, they found the second adult: Big Sam.

Bamforth said both dinosaurs are believed to have been the elders in the herd.

“Their distinguishing feature is that, instead of having a horn on their nose like a triceratops, they had this big, bony bump called a boss. And they have big, bony bumps over their eyes as well,” she said.

“It makes them look a little strange. It’s the one dinosaur that if you find it, it’s the only possible thing it can be.”

The genders of the two adults are unknown.

Bamforth said the extraction was difficult because Big Sam was intertwined in a cluster of about 300 other bones.

The skull was found upside down, “as if the animal was lying on its back,” but was well preserved, she said.

She said the excavation process involved putting plaster on the skull and wooden planks around if for stability. From there, it was lifted out — very carefully — with a crane, and was to be shipped on a trolley to the museum for study.

“I have extracted skulls in the past. This is probably the biggest one I’ve ever done though,” said Bamforth.

“It’s pretty exciting.”

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
