How to view a lunar eclipse, full ‘flower moon," and meteor shower this weekend

Published

 on

With bright meteors blazing across the sky from the Aquariids meteor shower and a chance to see a lunar eclipse, Friday will be the time to look up to the sky for a day of spectacular celestial events.

Anyone venturing out to spot a meteor with this year’s Aquariids show could see up to 20 meteors per hour, but you’ll have to be up early — the best times to try to see a meteor will be just before dawn on Friday, Saturday or Sunday. The event’s estimated peak time is at 11 a.m. ET Saturday.

Alongside the shower comes the May flower moon, the first full moon of the “month of flower,” and its almost perfect alignment with the sun and Earth. That alignment will create what is known as a penumbral lunar eclipse, which is when the moon enters Earth’s outer shadow. This event will be between 11:13 a.m. and 3:31 p.m. ET Friday but won’t be visible in the Americas because the moon isn’t up then. But it will cause a dimming of the lunar surface for those in Africa, Asia and Australia.

The collision of celestial events might be exciting for space enthusiasts, but together they could hinder your view. With the moon completely full, the Aquariids will have to compete with some bright light interference to be seen in the night sky.

“I would suggest going out around 3 o’clock in the morning. Get a lawn chair and put the moon at your back,” said Robert Lunsford, fireball report coordinator for the American Meteor Society. “Look for these fast meteors shooting upward from the eastern horizon. Not all meteors you see will be Eta Aquariids, but they’re easy to tell because the Eta Aquariids are very fast.”

More on the lunar eclipse

During an eclipse, the shadow Earth casts is broken up into two sections: the umbra, which is the dark center, and the penumbra, the fainter outer shadow. During a penumbral eclipse, the moon stays on this outer ring, appearing as if it is dimming, but not completely darkening like a total lunar eclipse.

“The moon passes through the portion of the Earth’s shadow, and because it grazes the shadow it’s not quite as much distance as when it passes through the entire shadow of the Earth,” said Noah Petro, chief of NASA’s Planetary Geology, Geophysics and Geochemistry Lab, noting that it will be hard for someone to see. “The dimming of the moon is very slight, but if someone is in a dark place, they may notice the full moon is not quite as bright as normal.”

Still, Petro encouraged people in Asia and Australia to get out and see the lunar eclipse.

“Any chance people have to get out and look at the moon is an excellent opportunity to connect with our moon. Eclipses (penumbral or total) are great excuses to take a look at the moon and start looking at it more regularly!”

More on the Eta Aquariids

Every annual meteor shower has a radiant, the constellation from which the meteors appear to be originating. The Aquariids constellation is Aquarius, hence the shower’s name, and lies on the ecliptic, the sun’s path in the sky.

The Aquariids are only visible just before dawn since the radiant rises a few hours before the sun does, limiting the evening hours in which you can see them.

Those in northern areas, such as Canada, will have a smaller window to see activity, the American Meteor Society’s Lunsford said, while those in the Southern Hemisphere will have a slightly longer time frame where the radiant will be up, and the sun will still be down.

The Aquariids typically produce meteors that are faster than others, including the last event of the Lyrids in April, which means they tend to produce more persistent trains, smoke trails caused by disintegration of the blazing fast meteors. A meteor’s speed is determined by the angle in which it encounters Earth, with the Aquariids mostly colliding with the atmosphere head-on, Lunsford said.

Lunsford also mentioned that this year’s peak is expected to see slightly more meteors per hour, and next year even more so due to perturbation that has caused the debris trail to move closer to Earth. In 2024, Lunsford estimates that those within the Southern Tropics could see a range of 75 to 100 meteors per hour.

“You don’t need expensive equipment; it is a way that you can participate in astronomy without spending a lot of money, and it’s fun,” Lunsford said. “You can actually make useful scientific contributions by counting the number of meteors you see and trying to separate them into Lyrids or non-Lyrids.

“Besides, it’s like having an early Fourth of July celebration … to see a shooting star. And, who knows, you can make a whole lot of wishes if you see a bunch.”

More meteor showers to come

The Eta Aquariids will be hanging around until May 27, but if you missed their peak, there are plenty more opportunities to spot a meteor.

Here are the remaining meteor showers of 2023 and their peak dates:

• Southern Delta Aquariids: July 30-31

• Alpha Capricornids: July 30-31

• Perseids: August 12-13

• Orionids: October 20-21

• Southern Taurids: November 4-5

• Northern Taurids: November 11-12

• Leonids: November 17-18

• Geminids: December 13-14

• Ursids: December 21-22

Solar and lunar eclipses

The penumbral lunar eclipse event is only viewable to those in certain parts of the world, but there are other chances to see an eclipse in your area:

If you live in North, Central or South America, an annular solar eclipse will take place on October 14, when the moon moves in front of the Earth’s view of the sun, creating a crisp, fiery circle in the sky.

On October 28, a partial lunar eclipse will be viewable in Europe, Asia, Australia, Africa, parts of North America and much of South America.

More full moons

This year will have 13 full moons, with two in August. Here’s the list of full moons remaining in 2023, according to the Farmers’ Almanac:

• June 3: Strawberry moon

• July 3: Buck moon

• August 1: Sturgeon moon

• August 30: Blue moon

• September 29: Harvest moon

• October 28: Hunter’s moon

• November 27: Beaver moon

• December 26: Cold moon

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.”
