Jupiter's newest Flyby offered the most amazing views.

Jupiter.

The largest planet in the solar system-twice as much as all other planets combined. This enormous world was formed from the same clouds of dust and gas that became our sun and the rest of the planet.

But Jupiter Was the eldest son Of our planetary family. The massive gravitational field of the first planet, Jupiter, most likely formed the rest of the entire solar system.

Jupiter may or may not have played a role in the position where all planets orbit around the sun. This is because the asteroid belt is a vast area that can be occupied by other planets. Jupiter’s gravity.

Gas giants such as Jupiter also throw entire planets out of the solar system or head towards stars.

Millions of years later, the formation of Saturn probably helped Jupiter escape this fate.

Jupiter can also act as a “comet catcher”. Otherwise, comets and asteroids that could fall into the inner solar system and attack a rocky world like Earth would instead be captured by Jupiter’s gravitational field and ultimately Jump into the clouds of Jupiter.

But at different times in Earth’s history, Jupiter May have had the opposite effect, Throwing an asteroid in our direction-it’s generally a bad thing, but water-rich rocks that lead to the blue planet we know today may have entered Earth.

Jupiter is a window into our solar system’s past. The past, literally shrouded under Jupiter’s clouds, is the reason why Juno, the spacecraft currently orbiting Jupiter, was so named. Mythical Jupiter’s wife Juno was able to peek into the cloud cloak that Jupiter uses to conceal himself and his injustice.

But in this case we are looking at our own history through the clouds of Jupiter. Juno entered Jupiter’s orbit on July 5, 2016 after traveling for almost five years to reach the gas giant.

Falling into Jupiter’s gravitational well, Juno reached a speed of 210,000 km/h. This is one of the fastest speed records ever set by any human-made object.

Juno is on a very eccentric 53-day orbit. During the Perijove or nearest orbital approach, Juno scans Jupiter at an altitude of 4,200 km, then sweeps 8.1 million km outward. Juno’s orbit is designed to navigate the weak areas of Jupiter’s incredibly powerful magnetic field.

Second power over the sun itself, Jupiter’s magnetic field accelerates high-energy particles emanating from the Sun, creating a powerful band of radiation surrounding the planet.

In addition to agile navigation, Juno’s electronics are enhanced against radiation through a “radiation vault”, a 1 cm thick titanium shell that houses sensitive scientific equipment.

One of the devices that dazzle us all on Earth is JunoCam. RGB color cameras visually image Jupiter’s clouds as the probe buzzes each orbit in 2 hours, consuming as little Jupiter’s radiation time as possible.

Most recently, Juno completed Perijove 29, some photos published by “Software Engineer, Planetary and Climate Data Wrangler, Scientific Data Visualization Artist”. Kevin Gil.

JunoCam isn’t really part of Juno’s main science mission. However, the camera serves the main function. Let Juno travel with us.

I think it’s really great. Sometimes astrophotography is more thought of as art than science.

But as an astrophotographer, I believe that this image inspires future scientists, raises a general awareness of ongoing scientific missions and public support for science funding. Speaking of which, what has our science discovered about the largest and greatest worlds?

One of Jupiter’s greatest mysteries is in its heart. Juno helped solve the ongoing debate about how Jupiter formed in the planetary science community.

There were two possibilitiesThe first is that Jupiter began as a rocky world, a nucleus that is about 10 times the mass of the Earth. The gravitational force of this nucleus attracted the surrounding hydrogen and helium until the formation of Jupiter as we know it. Its original rocky world was buried under a swirling vortex.

The second possibility is that the vortex of the rotating circular planetary disk of our early solar system collapsed on its own and Jupiter formed directly without a rocky core. Both theories account for different conditions when the solar system begins. Juno is not a solid core, but “ambiguous” or “Dilution“main point.

Jupiter appears to have been formed from a rock body, but its core is spread throughout Jupiter’s interior rather than being located at the center of the planet.

The dilution of the nucleus appears to be the result of a massive planet-sized impact on Jupiter that broke the initial nucleus and spread it over half the diameter of Jupiter.

Imagine being there for an event like that. Jupiter is swallowing up planets in our solar system that we never knew. The history of our place in space has been revealed.

We also learned that Jupiter’s winds dive deep beneath the outer clouds, the Great Red Spot is hundreds of kilometers deep, and from Jupiter’s North Pole and Antarctica we have seen huge cyclones capable of swallowing the country.

Jupiter is currently the brightest object in the night sky after sunset. If the sky is clear and you can see, look south!

Remember that the bright spot is a huge world hundreds of times the size of the Earth and millions of kilometers away, but potentially one of the key elements of your existence. Jove is amazing.

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.”
