NEW YORK (AP) — NASA’s Webb Space Telescope has identified new clues about the surface of Pluto’s largest moon.

It detected for the first time traces of carbon dioxide and hydrogen peroxide on the surface of Charon, which is about half Pluto’s size.

Previous research, including a flyby from NASA’s New Horizons spacecraft in 2015, revealed that the moon’s surface was coated by water ice. But scientists couldn’t sense chemicals lurking at certain infrared wavelengths until the Webb telescope came around to fill in the gaps.

“There’s a lot of fingerprints of chemicals that we otherwise wouldn’t get to see,” said Carly Howett, a New Horizons scientist who was not involved with the new study.

The research published Tuesday in the journal Nature Communications.

Pluto, a dwarf planet, and its moons are in the far fringes of our solar system in a zone known as the Kuiper Belt. Besides water ice, ammonia and organic materials were previously detected on Charon. Both Pluto and Charon are over 3 billion miles (4.83 billion kilometers) from the sun and are likely too chilly to support life.

Scientists think the hydrogen peroxide may have sprung from radiation pinging off water molecules on Charon’s surface. The carbon dioxide might spew to the surface after impacts, said study co-author Silvia Protopapa from the Southwest Research Institute.

The latest detection is key to studying how Charon came to be and may help scientists tease out the makeup of other faraway moons and planets.

Community-based care a move in the right direction

Editorial 4 minute read 2:01 AM CDT

It’s not a case of reinventing the wheel. It’s a case of recognizing how the wheel actually works and realizing that a symptom can be far away from the whole illness.

And it is a pragmatic, practical, numbers-based solution for a growing problem.

Earlier this month, Health Minister Uzoma Asagwara announced that the province would be funding 103 community-based care spaces in Winnipeg. The spaces will be for patients who need shelter or specialized supports — and can’t be discharged from much-needed hospital beds without it.

“We’re talking about, in some cases, some Manitobans, some patients who have been waiting in (hospital) beds for the right place to go in communities for hundreds, if not thousands of days,” Asagwara said. “Some folks with very complex needs are now going to get the care they need in community.”

De Havilland calls for national water bomber fleet as it scrambles to meet demand

Christopher Reynolds, The Canadian Press 7 minute read Updated: Yesterday at 1:49 PM CDT

MONTREAL - On July 13, a pair of Canadair water bombers touched down on the Seine River, skimming along its surface to refill their water tanks as they battled a wildfire south of Paris.

The "super scoopers," with their signature ketchup-red wing tips on a mustard-yellow body, sucked up 6,000-plus litres from France’s most famous waterway in one go as part of a fight against the flames then rampaging across Europe.

The event in north-central France underscored how wildfires are ranging even farther from their traditional grounds and fuelling an urgent need for water bombers to fend off climate disasters.

The iconic Canadair turboprops serve as the only amphibious firefighting aircraft currently in production built from the outset for that purpose, rather than being retrofitted to douse flames.

Salvation Army calls on Winnipeggers to donate merchandise as sales soar

The Salvation Army is taking donated merchandise from other regions to stock its Winnipeg thrift stores as increasing sales outpace local donations.

Retail activity at the charity’s eight Winnipeg locations grew more than 10 per cent year over year during several months, from January through April, and again in June.

Although local donations remain strong, they haven’t kept pace with demand, prompting the organization to supplement inventory with merchandise from elsewhere.

Ted Troughton, managing director of the Salvation Army’s thrift store operations, said rising living costs are bringing in new customers.

Province looks to keep nearly $1M from traffic stop

The RCMP constable could see that Alireza Haghgoo was nervous.

The 22-year-old, seated as a passenger in a rental Nissan SUV the Mountie pulled over for speeding outside Brandon in late July, was breathing heavily and tapping his foot constantly, as the carotid artery on his neck visibly pumped blood.

He had good reason to be jumpy — considering Mounties found nearly $1-million in cash that justice officials allege is drug money in the car he and Ahmad Shahpoor Ahmadi, 44, were driving from Calgary to Toronto.

The province’s director of criminal property forfeiture filed a lawsuit in the Court of King’s Bench last week in an attempt to keep the more than $956,000 in cash seized during the traffic stop on July 31 as well as a more than $70,000 watch.
