Amazon warns of phony solar eclipse glasses sold online – CityNews Toronto

Published

Amazon is warning certain customers of uncertified solar eclipse glasses that were posted and sold online.

Millions of people across a swath of North America, including parts of Eastern and Atlantic Canada, will experience a few minutes of darkness in the middle of the day on Monday as the moon passes in front of the sun.

As a result, many have been flocking to purchase solar eclipse glasses needed to witness the spectacle in the sky. As it turns out, some companies appear to be profiting by selling illegitimate eye protection.

Breakfast Television received an email from an Amazon spokesperson following the sale of such solar eclipse eyewear. The product, which has since been removed from the website, was described as “Eyes Protection Paper Frame Glasses for Solar Eclipse Viewing.”

“The product listed was not included in the American Astronomical Society’s [AAS] list of safe suppliers of solar eclipse viewers and filters and, therefore, may not be safe for viewing a solar eclipse,” the email read.

“If you still have this product, out of an abundance of caution, we recommend you not use it for the upcoming eclipse on April 8 and review the following information for more details, including how to view a solar eclipse safely and how to identify unsafe eclipse glasses.”

The AAS does not recommend “searching for eclipse glasses on Amazon, eBay, Temu, or any other online marketplace and buying from whichever vendor offers the lowest price.”

Meanwhile, Amazon said refunds will be issued to those who purchased the alleged phony product.

“If you made this purchase for someone else, please notify the recipient immediately and provide them with the information,” the spokesperson noted. “The safety and satisfaction of our customers is our highest priority. We regret any inconvenience this may cause you.”

Some AAS-approved solar eclipse glasses include Halo Eclipse Spectacles and Solar Eyewear.

How to test your solar eclipse glasses

Residents are asked not to look directly at the sun during the eclipse, as it could cause permanent damage to their eyes. The only time to look at the eclipse without glasses is when the moon fully covers the sun during totality, which lasts only three or four minutes.

The AAS issued a statement on March 22 warning of counterfeit solar eclipse glasses. It noted that safe solar viewers block all but a minuscule fraction of the sun’s ultraviolet (UV), visible, and infrared (IR) light. 

“We used to recommend that you make sure the eclipse glasses you’re buying come from one of the manufacturers on our list,” the AAS said.

“But now that we know that fake, unsafe eclipse glasses are being misrepresented as coming from at least one of these manufacturers, we need to urge a more cautious approach.”

The AAS mentioned that there is a way to test solar eclipse glasses to ensure they’re genuine and safe. It involves a few steps, including wearing them indoors and staring at bright lights, which should appear faint, and then trying them outside on a sunny day. Very little light should be observed through the glasses.

The third step is staring at the sun with the glasses on for less than a second. The AAS says you should see a sharp-edged, round disk (the sun’s visible “face”) that’s comfortably bright.

“Depending on the type of filter in the glasses, the sun may appear white, bluish-white, yellow, or orange,” the AAS wrote. “If your glasses pass all three tests, they are probably safe.”

How to make a pinhole camera with everyday items for safe solar eclipse viewing

Regular sunglasses won’t block enough light, and NASA says even when the sun is 99 per cent obscured, it can still cause damage.

One way to observe the phenomenon is with a pinhole camera—more accurately described as a projector—that can be created with items most of us already have at home.

A basic pinhole projector can be made by pushing a pin through a piece of paper or cardboard to create a tiny hole. When you take that paper outside and cast a shadow with it on the ground, the bit of light that passes through the hole projects “a little tiny image of the sun” and allows safe tracking of the eclipse.

If you’re willing to put in a little bit more effort and want to engage kids in a fun activity, you can create a pinhole camera out of a cereal box, shoe box, or other cardboard box that is easily held to the eye.

For this project, you will need a piece of white paper, scissors, aluminum foil, a pin and some tape.

This eclipse will be the first total solar eclipse to be visible in Canadian provinces since February 26, 1979, the first in Mexico since July 11, 1991, and the first in the United States since August 21, 2017.

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.”
