April's total solar eclipse promises to be the best yet for experiments – CityNews Toronto

Published

CAPE CANAVERAL, Fla. (AP) — April’s total solar eclipse promises to be a scientific bonanza, thanks to new spacecraft and telescopes — and cosmic chance.

The moon will be extra close to Earth, providing a long and intense period of darkness, and the sun should be more active with the potential for dramatic bursts of plasma. Then there’s totality’s densely populated corridor stretching from Mexico to the U.S. to Canada.

Hundreds if not thousands of the tens of millions of spectators will double as “citizen scientists,” helping NASA and other research groups better understand our planet and star.

They’ll photograph the sun’s outer crownlike atmosphere, or corona, as the moon passes between the sun and Earth, blotting out sunlight for up to 4 minutes and 28 seconds on April 8. They’ll observe the quieting of birds and other animals as midday darkness falls. They’ll also measure dropping temperatures, monitor clouds and use ham radios to gauge communication disruptions.

At the same time, rockets will blast off with science instruments into the electrically charged portion of the atmosphere near the edge of space known as the ionosphere. The small rockets will soar from Wallops Island, Virginia — some 400 miles outside totality but with 81% of the sun obscured in a partial eclipse. Similar launches were conducted from New Mexico during last October’s “ring of fire” solar eclipse that swept across the western U.S. and Central and South America.

“Time for the biggie! It is pretty exciting!!!” Embry-Riddle Aeronautical University’s Aroh Barjatya, the rockets’ mission director, said in an email.

NASA’s high-altitude jets also will take to the air again, chasing the moon’s shadow with improved telescopes to study the sun’s corona and surrounding dust.

“Dust sounds boring,” acknowledged NASA’s eclipse program manager Kelly Korreck. “But at the same time, dust is actually really interesting. Those are the leftover remnants from when the solar system was forming.”

More than 600 weather balloons will be launched by college students along the track, providing livestreams while studying atmospheric changes. Cloudy skies shouldn’t matter.

“Lucky for us, the balloons flying to 80,000 feet and above don’t care if it’s cloudy on the ground,” said Angela Des Jardins, an astrophysicist at Montana State University who’s coordinating the nationwide project.

And if the Federal Aviation Administration approves, a 21-foot (6.5-meter) kite will lift a science instrument three miles (5 kilometers) above Texas in an experiment by the University of Hawaii’s Shadia Habbal. She, too, wants to get above any clouds that might hamper her observations of the sun.

Normally hidden by the sun’s glare, the corona is on full display during a total solar eclipse, making it a prime research target. The spiky tendrils emanating thousands of miles (kilometers) into space are mystifyingly hotter than the sun’s surface — in the millions of degrees, versus thousands.

“In terms of the value of total eclipses, science still cannot explain how the corona is heated to such extreme temperatures,” said retired NASA astrophysicist Fred Espenak, better known as Mr. Eclipse for all his charts and books on the subject.

The U.S. won’t see another total solar eclipse on this scale until 2045, so NASA and everyone else is pulling out all the stops.

April’s eclipse will begin in the Pacific and make landfall at Mazatlan, Mexico, heading up through Texas and 14 other U.S. states before crossing into Canada and exiting into the Atlantic at Newfoundland. Those outside the 115-mile-wide (185-kilometer-wide) path, will get a partial eclipse.

Scientists got a taste of what’s to come during the 2017 total solar eclipse that stretched from Oregon to South Carolina. This time, the moon is closer to Earth, resulting in more minutes of darkness and a wider path.

“Any time we can observe for longer, that gives scientists more data,” Korreck said.

Another scientific bonus this time: The sun will be just a year away from its maximum solar activity, as opposed to 2017 when it was near its minimum. That means lots more action at the sun, possibly even a coronal mass ejection during the eclipse, with massive amounts of plasma and magnetic field blasted into space.

Plus there are two new spacecraft out there studying the sun: NASA’s Parker Solar Probe and the European Space Agency and NASA’s Solar Orbiter. They’ll join other spacecraft on eclipse duty, including the International Space Station and its astronauts.

Closer to home, April’s eclipse, unlike previous ones, will pass over three U.S. radar sites typically used for monitoring space weather. The stations will tune in to what’s happening in the upper atmosphere as the skies dim.

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

 on

 

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

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.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
