Annular solar eclipse 2024: Everything you need to know about the next solar eclipse

Published

 on

Now that the “Great North American Eclipse” is over, you may be itching for the next opportunity to witness another celestial marvel. So when is the next solar eclipse?

The next total solar eclipse is more than two years out, on Aug. 12, 2026, in Greenland, Iceland and Spain. However, on Oct. 2, 2024, a “ring of fire” annular solar eclipse will pass over parts of the Pacific Ocean, southern Chile and southern Argentina.

Whereas 43.8 million people were able to experience totality for the April 8, 2024, eclipse in North America, only 175,000 people will have that opportunity for the Oct. 2 annular solar eclipse, according to Time and Date. The paths of both eclipses cross in the Pacific Ocean.

During an annular solar eclipse, it is NEVER safe to look directly at the sun without solar eclipse glasses designed for solar viewing. Read our guide on how to observe the sun safely.

So, ready to go eclipse chasing? Here’s everything you need to know about the annular solar eclipse on Oct. 2, 2024, in Chile and Argentina.

What is an annular solar eclipse?

The Oct. 2 eclipse will be very similar to the annular solar eclipse on Oct. 14, 2023, which was visible across the U.S. Southwest, Central America and South America. All solar eclipses occur when a new moon is positioned precisely between Earth and the sun and casts its shadow on Earth. However, unlike a total solar eclipse, an annular solar eclipse occurs when the moon is slightly farther from Earth. So, even when the disks align from our perspective, the moon’s shadow doesn’t completely block out the sun’s light. Instead, a ring of sunlight is visible around the moon.

The eclipse on Oct. 2, 2024, will have an eclipse magnitude of 0.9326, according to EclipseWise.com. That means about 93% of the sun will be blocked by the moon during the eclipse, resulting in an “annulus” (Latin for “ring”). The moon will appear 6.4% smaller than average, according to MoonBlink.

The closer the observer is to the centerline, the more circular the ring of fire will be and the longer it will last. But experienced eclipse chasers often observe from the edge of the path during an annular solar eclipse to see extended views of Baily’s beads fizzing around where the limb of the moon appears to touch the sun. They can be visible for several minutes.

From where can you see the Oct. 2 annular solar eclipse?

The ring of fire will be visible only within a path of annularity that passes across the Pacific Ocean, southern Chile and southern Argentina.

This area will include the volcanic island of Rapa Nui/Easter Island, an iconic travel destination that’s famous for the mysterious stone statues called moai, some of which reach 40 feet (12 meters) tall and weigh 75 tons. The island, which is only 63 square miles (163 square kilometers), is located 2,300 miles (3,700 km) from the Chilean coast, making it the most isolated inhabited landmass on Earth. Remarkably, it will be the second time a central solar eclipse has been visible from this tiny Pacific island in recent decades, with a total solar eclipse glimpsed there on July 11, 2010. The next total and annular eclipses there will be in 2324 and 2345, respectively.

A good option would be to position yourself slightly south of a moai at multiple sites to get a view of the ring of fire just above one of the statues, according to the Atlas of Solar Eclipses — 2020 to 2045. Iconic locations will include the platform at Ahu Tongariki, where 15 moai are positioned on a 200-foot-long (60 m) ceremonial platform and nearby Rano Raraku.

October’s ring of fire will also be visible from southern Patagonia in Chile and Argentina. The path will be 180 to 185 miles (290 to 300 km) wide.

Where and when can I see the Oct. 2 annular solar eclipse?

Here are some places eclipse chasers will gather for this annular solar eclipse:

  • Rapa Nui/Easter Island, Chile (5 minutes, 38 seconds to 6 minutes, 12 seconds of annularity starting at 14:03 EAST, 67 degrees above North)
  •  Cochrane, Chile (5 minutes, 40 seconds of annularity starting at 17:21 CLST, 26 degrees above NNW)
  •  Perito Moreno National Park, Argentina (6 minutes, 17 seconds of annularity starting at 17:21 ART, 25 degrees above NNW)
  •  Puerto Deseado, Argentina (3 minutes, 22 seconds of annularity starting at 17:27 ART, 20 degrees above NNW)
  •  Puerto San Julian, Argentina (5 minutes, 12 seconds of annularity starting at 17:24 ART, 21 degrees above NNW)

Organized eclipse-viewing tours include Sky & Telescope, TravelQuest and AstroTrails. All are experienced eclipse tour operators that are headed to Rapa Nui/Easter Island.

What will the weather be like for the Oct. 2 annular eclipse?

It’s always best to travel somewhere you want to visit regardless of a solar eclipse. That certainly applies to the Oct. 2 event, because the prospects of a completely clear sky are relatively low. The chances of clouds that day are 75% for Rapa Nui/Easter Island,, 90% for Perito Moreno National Park, and 65% to 70% for locations on Argentina’s Atlantic coast, according to Time and Date.

On Rapa Nui/Easter Island, the cooling of the land could cause convective clouds to dissipate, according to Eclipsophile, with the south coast statistically slightly favored. The chances of seeing the ring of fire are smallest on Chile’s Pacific Coast and highest on Argentina’s Atlantic coast. The latter has the least interesting scenery of anywhere in the path, but the eclipse will arguably be a more dramatic sight because it will occur much lower in the sky.

Why is the Oct. 2, 2024, annular solar eclipse special?

The Oct. 2, 2024, annular solar eclipse is special for three very different reasons. First, it follows the Great North American Eclipse of April 8 — so interest in solar eclipses should be high, and many eclipse chasers will travel to see it.

Second, it’s a long eclipse, with the ring of fire lasting up to 7 minutes, 25 seconds. That’s much longer than the 4 minutes, 52 seconds possible in the U.S. during the last annular solar eclipse on Oct. 14, 2023.

Third, the best place to view this event is a truly iconic destination: Rapa Nui, also called Easter Island.

Where to see the partial solar eclipse on Oct. 2

Although a ring-of-fire eclipse will be visible only from the aforementioned areas of Chile and Argentina, other areas will experience a partial solar eclipse on Oct. 2. These areas include parts of the Pacific Ocean and the southern half of South America. Here’s what percentage of eclipse will be seen from major cities and destinations in the partial-eclipse zone:

  • Galapagos Islands (1%)
  • La Paz, Bolivia (1%)
  • Rio de Janeiro, Brazil (9%)
  • São Paulo, Brazil (10%)
  • Buenos Aires, Argentina (42%)
  • Montevideo, Uruguay (42%)
  • Santiago, Chile (44%)
  • Villarrica, Chile (63%)
  • El Calafate, Argentina (83%)
  • Falkland Islands (84%)
  • South Georgia Island (76%)
  • Punta Arenas, Chile (75%)
  • Ushuaia, Argentina (72%)
  • Elephant Island (56%)
  • Port Lockroy, Antarctica (44%)

After October 2024, when is the next annular solar eclipse?

Here are the dates and locations for some upcoming annular solar eclipses:

  • Feb. 17, 2026: Antarctica
  • Feb. 6, 2027: Chile, Argentina, Uruguay, Côte d’Ivoire, Ghana, Togo, Benin and Nigeria
  • Jan. 26, 2028: Galapagos Islands, Ecuador, Brazil, French Guiana, Portugal, Morocco and Spain
  • June 1, 2030: Algeria, Tunisia, Greece, Turkey, Russia, Kazakhstan, China and Japan

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.”
