The first total lunar eclipse of 2022 was about to dye the moon red on Sunday night. A full “Venus Moon” will bathe this weekend in a rusty bronze light as the Earth’s shadow sweeps across it, creating a spectacle visible across much of North America.

The moon will turn red during the total lunar eclipse on Sunday night – Valley Post
It is the first of two total lunar eclipses that can be seen from the United States this year. Scheduled to take place on the night of November 7, the next show will miss parts of northwestern North America from the Sunday night show.
What is a total lunar eclipse?
Eclipses of all shapes occur when another object obscures. In the event of a total lunar eclipse, the Earth is mediated between the Sun and the Moon. You might expect it to block sunlight from reaching the moon, and make it disappear, but that doesn’t happen. Instead, some of the sunlight around the Earth’s circumference creeps through our atmosphere and spreads toward the moon.
For this to happen, the Sun, Earth, and Moon must be in one line. This only happens during the full moon.
total solar eclipse, on the other hand, occurs during new moons, when the moon slips between the earth and the sun. This extinguishes sunlight from reaching a narrow passage of land, turning day into night. A solar eclipse also allows the sun’s white corona, or atmosphere, to be visible, which is usually eclipsed by scorching sunlight.
Solar and lunar eclipses come in pairs approximately two weeks apart; The last partial solar eclipse, on April 30, was visible from South America.
A total lunar eclipse will begin as an unnoticeable lunar eclipse—a subtle darkening that is difficult to perceive to an untrained observer. This is the time when the widest and most diffuse portion of the Earth’s shadow begins to sweep across the lunar surface from the lower left to the upper right.
The partial phase of the eclipse will occur, when the edge of darkness, or the darkest part of the Earth’s shadow, first makes contact with the Moon. You will see a veil of darkness traversing the moon, the edge of which is a gentle curve representing the shape of the Earth. The shadow curve will be gentler than the moon’s curve, because the Earth is larger.
Once the shadow swallows it whole, the color of the moon will turn red. That’s because the only light that reaches the moon is what flows through the Earth’s atmosphere. The shorter wavelengths/higher frequencies of light scatter away, leaving only the longer wavelengths, which are red in color, capable of penetrating the atmosphere at a low angle of incidence. It is the same premise that makes sunrise and sunset red. Therefore, you see the light of sunrise and sunset constantly synchronized on the moon.
A maximum eclipse occurs when the moon is strongly etched into the Earth’s shadow, immersed in nothing but a frightening red light. The color of a lunar eclipse actually varies depending on how polluted the atmosphere is; Astronomers have evaluated color gradients on dungeon scale, where zero represents a barely visible eclipse and the number four represents a copper eclipse. It is known that volcanic eruptions and the presence of aerosols reduce the vitality of lunar eclipses.
All times listed are Eastern Time:
Penumbral Eclipse begins: 9:32:05 PM ET
Start the partial eclipse: 10:27:52 PM ET
Start college: 11:29:03 PM ET
Max Eclipse: 12:11:28 AM ET
College end: 12:53:55 AM ET
Ending partial eclipse: 1:55:07 AM ET
Penumbral Eclipse End: 2:50:49 AM ET
Noticeable: For some on the West Coast, the moon won’t rise until its fullness has already begun. Moonrise in San Francisco, for example, is set at 8:06 p.m. PST, just 23 minutes before college starts.
How special is the total lunar eclipse?
A lunar eclipse is not nearly as special as a total solar eclipse. A lunar eclipse can be seen from the entire night side of the Earth, as the moon can be seen from anywhere. Most places experience one or two total lunar eclipses annually.
On the other hand, a total solar eclipse can only be seen from a particular location once every 375 years on average. The college trail may be a sliver barely a mile wide, and the experience is surreal. The next day to be seen in the United States will be Monday, April 8, 2024.
Patches of clouds will spread sporadically across the East Coast, the International West, the Sierra Nevada, and the Pacific Northwest. The center of the country will see vast expanses of clear sky favorable for viewing.
A more accurate prediction will be made in the coming days.

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