Psyche, an asteroid believed to be worth $10,000 quadrillion, is observed through Hubble Telescope in new study – CNN

Published

A new study published Monday in The Planetary Science Journal takes a closer look at this mysterious asteroid, using data from the Hubble Telescope.
Located between Mars and Jupiter, Asteroid 16 Psyche is one of the most massive objects in the asteroid belt in our solar system, and with a diameter of about 140 miles, it is roughly the same length as Massachusetts (if you exclude Cape Cod).
The exact composition of Psyche is still unclear, but scientists think it’s possible the asteroid is mostly made of iron and nickel. It’s been hypothesized that a piece of iron of its size could be worth about $10,000 quadrillion, more than the entire economy on our planet.
Scientists believe that Psyche could be the metallic core of an early planet that lost its mantle and crust due to collisions that might have occurred early in the formation of the solar system.
In 2022, NASA will send an unmanned spacecraft to Psyche to study it up close and better determine its composition.
In the meantime, the new study in The Planetary Science Journal looked at Psyche through the Hubble Telescope at two specific points in its rotation, to capture both sides of the asteroid.
The study includes the first ultraviolet observations of Psyche, furthering our understanding of its surface and its possible composition.
“We looked at the way that the ultraviolet light reflected off of the asteroid surface,” Tracy Becker told CNN. She is the lead author of the study and a planetary scientist at the Southwest Research Institute.
“The way the ultraviolet light was reflected from Psyche was very, very similar to the way iron reflects sunlight,” she explained.

The importance of studying Psyche

Studying Psyche could help us better understand those early times in the history of our solar system, when objects would have had “higher inclinations and crazier eccentricities,” and would have had more opportunities to collide with each other, Becker told CNN.
If Psyche is the metal core of a planet that never was, studying it more closely could tell us a lot about the core of our planet, which we wouldn’t be able to explore, Becker said.
The study also detected two possible signals of changes to the surface of Psyche due to solar winds, according to Becker.
“The first one was that as we went deeper into the UV, we started to see the asteroid get brighter, which is pretty rare,” Becker said.
“In the past, when we’ve seen that on certain planetary bodies, including the moon, that often tells us that it’s due to the charge particles from the sun interacting with the materials on the surface, causing this brightening. We call that space weathering,” she added.
The second signal, according to Becker, was the detection of iron oxide ultraviolet absorption bands.
“That could be implying that there is some sort of interaction with oxygen and the metal,” Becker said.
The charged particles from the sun could be causing the oxygen to interact with the materials now, or that interaction could have occurred a long time ago, according to Becker. Further study will be required to connect these findings to more information on when the asteroid first might have formed, Becker said.

Getting ready to visit Psyche

The study comes as the NASA mission to Psyche, led by Arizona State University, is plugging away.
“We’re building space hardware and getting ready for our launch in August of 2022,” Lindy Elkins-Tanton, a planetary scientist who is the principal investigator for the mission, told CNN. Elkins-Tanton is also a minor author of the new study.
The mission’s launch, originally slated for 2023, was moved up to 2022, and will take place from Cape Canaveral Air Force Station, using a SpaceX Falcon Heavy rocket.
The unmanned spacecraft should reach Psyche by January 2026, and it will be orbiting the asteroid for 21 months, mapping it and studying it from a distance, Elkins-Tanton explained.
When it gets to Psyche, the mission will be the first to ever photograph the asteroid.
Scientists plan on making these images immediately available for everyone on Earth to see and study further, possibly within 30 minutes of taking them, Elkins-Tanton said.
“Everyone in the world is going to be able to look at Psyche at the same time we are, and scratch their heads and say, what is this thing?” she added.

What we want to know about Psyche

Elkins-Tanton said she is thrilled about the scientific community’s interest in learning more about Psyche ahead of the mission, which will be a true test for the theories about the asteroid put forth so far.
“There’s the opportunity for people to make measurements, hypotheses and predictions, and then actually find out if they’re right, because we’re going to go and find out,” she added.
The questions Elkins-Tanton hopes to find answers to could help us understand “the ingredients that went into making the cake” — that is, our planet.
“Does [Psyche] have oxygen mixed into it, the way this study has indicated it might have some? Or other light elements, like sulfur, or even potassium, mixed into the metal phase? Can we say something about the temperature and pressure conditions under which it formed, based on its composition, that would tell us something about the size of the body it came from, and the sorts of things that went into making up our Earth?”
“One thing we can pretty much promise right now is that Psyche is going to surprise us,” Elkins-Tanton said. “Everything we know about it now is probably going to be wrong when we go there and find out.”

A $10,000 quadrillion asteroid

About that staggering estimate that Psyche might be worth $10,000 quadrillion, Elkins-Tanton says she takes responsibility for coming up with that number during interviews when the NASA mission was first announced in 2017.
While the conversation on mining asteroids for resources is developing here on Earth, Psyche is not the target we should strive for, according to Elkins-Tanton.
“We cannot bring Psyche back to Earth. We have absolutely no technology to do that,” Elkins-Tanton said.
Even if it was possible to bring back metals from Psyche without destroying the Earth, that would quite possibly collapse the markets, Elkins-Tanton said.
“There are all kinds of problems with this, but it’s still fun to think about what a piece of metal the size of Massachusetts would be worth.”

Space mining and our imagination

Objects that are closer to Earth are more realistic candidates for space mining, according to Elkins-Tanton. One of the most interesting ideas is to use asteroids as a source for water, which can be made into rocket fuel.
“Most of the nearest asteroids don’t have water ice on them, but they do have minerals that contain water bound up in their crystal lattices,” and that could be accessed by heating up the minerals, Elkins-Tanton explained.
“They could almost be like little refueling stations,” she said.
“This is a bit ahead of ourselves in terms of what we can actually do, but I love it because it shows how aspirational people can be, and it shows how powerful our imaginations are,” Elkins-Tanton told CNN.
“To me, that’s the great strength of space exploration — it gives us that motivation to do great things,” she added.

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.”
