‘Amazement and happiness’: Canadian sensor on James Webb telescope passes first tests

Far out in deep space, four times the distance between Earth and its moon, a piece of Canadian technology that could help reshape our understanding of the universe has passed its first crucial tests.
The systems that aim the massive James Webb Space telescope, designed and built through the Canadian Space Agency, have been used to lock on to a target star — a sign that the millions of dollars and thousands of hours spent on the signature project are going to work out just fine.
“It’s extremely satisfactory seeing everything coming into place,” said Jean Dupuis, a senior mission scientist with the agency. “It’s a sense of amazement and happiness.”
The James Webb, the result of $13 billion and more than two decades of work, is meant to be the successor to the Hubble Space Telescope, the instrument that mesmerized stargazers with its stunning images of the heavens. Webb, however, will orbit much deeper in space — about 1.6 million kilometres out — and be anywhere from a hundred to a million times more sensitive.
Launched in late December, it is designed to study the nature of planets beyond our solar system and what the oldest galaxies around can tell us about the birth of the universe. Webb will be able to analyze exoplanetary atmospheres and gather data from so-called “First Light” galaxies, formed 13.6 billion years ago.
But it all would have been a goofy-looking piece of space junk if the Fine Guidance Sensor had failed.
“(The sensor) is mission critical,” said Dupuis, who was in the NASA control room Jan. 31 when operators flicked on its power switch after the long voyage from Earth.
“There was a lot of pressure on us,” he said. “Everybody was very happy.”
The sensor is now up and running, being used to align the telescope’s 18 mirrors. It also needs to cool down to below -200 C. That’s all likely to take until the summer.
Then, the sensor will be able to aim James Webb with stunning precision — down to a few milli-arcseconds.
“You would be able to point at a human hair from a couple kilometres away,” Dupuis said. “It’s pretty much pushing the limit of what can be done.”
Things have been going well for the mission. NASA announced in December that the telescope slipped into its orbit so neatly that the fuel savings mean it could operate for significantly longer than the original 10-year planned lifespan.
It’s not the only Canadian contribution to the James Webb. Its Near-Infrared Imager and Slitless Spectrograph, which will help analyze light the telescope observes, was also designed and built in Canada.
Canada has been part of the Webb project almost from the start. At least half of the 600 scientists in the Canadian Astronomical Society have been involved with it and dozens of scientists and engineers are part of its design team.
Canada has contributed almost $200 million since the project began in 1996. As a result, Canadian astronomers are entitled to five per cent of the telescope’s observation time.
In addition to exoplanets and First Light galaxies, Canadian researchers will use Webb to study asteroids and comets close to home to the effect stars have on the space around them in distant regions of the galaxy where new stars are born.
And anticipation is building.
“I can’t wait to see the data we’ll get,” said Dupuis.

StatCan report casts clouds on claims of a widespread labour shortage in Canada

A new report is casting doubt on the idea that Canada is facing a widespread labour shortage and bolsters the arguments by some labour economists that high job vacancies aren’t due to a shortage of workers.
The Statistics Canada analysis finds there are no labour shortages for jobs that require high levels of education, suggesting other factors, such as a mismatch in skills and pay, might be to blame for a high number of empty positions.
In the aftermath of the COVID-19 pandemic, labour shortages have grasped headlines from coast to coast as businesses have advertised more job openings than ever. Job vacancies skyrocketed to more than one million at one point last year.
The perceived countrywide labour shortage has put pressure on governments to help businesses find workers, including by increasing Canada’s immigration targets.
But the report published this week compares unemployment and job vacancies by education level and paints a more nuanced picture of the labour market.
“Things look really different depending on whether you look at vacancies that require a high level of education, versus those that require a high school diploma or less,” said René Morissette, the assistant director of social analysis and modelling division at the federal agency.
The report, which looked at labour data between 2016 and 2022, found for jobs requiring a bachelor’s degree or higher education, there were always fewer jobs available than people to fill them.
For example, there were 113,000 vacant positions requiring a bachelor’s degree or higher education in the fourth quarter of 2022, but 227,000 individuals who held such an education were unemployed during the same period.
But for positions that required a high school diploma or less, the shortage of workers only started in the third quarter of 2021.
Morissette said the findings don’t mean that there are no labour shortages in some markets, but shortages may not be as extensive as previously assumed.
“It’s certainly conceivable that there are local shortages in some in some positions,” Morissette said. “What we’re saying is that the shortages may not be as widespread as initially assumed in the early discussions about the high vacancy rates in Canada.”
For employers trying to fill vacancies that require a post-secondary education, the report says their hiring challenges cannot be attributed to a lack of workers available with those qualifications.
Instead, the difficulties may be the result of a mismatch in skills required for the job and those possessed by candidates. Another factor could be that employers aren’t offering wages that are on par with what job seekers expect.
The report also casts doubt on the hiring challenges facing firms trying to recruit workers with lower levels of education.
“The degree to which these job vacancies can be attributed to labour shortages in specific low-skilled occupations instead of relatively low-wage offers and fringe benefits or other factors remains an open question,” the report says.
Jim Stanford, an economist and the director of the Centre for Future Work, says the report from Statistics Canada busts “long-standing myths” about labour shortages in the country.
“If you were really short of labour, and you couldn’t find someone to do that minimum wage job at a McDonald’s restaurant, then why aren’t they either increasing the wage or trying to replace the work with machinery?” Stanford said.
“Neither are happening, which suggests to me that employers in general are quite happy with the current state of affairs, no matter how much they complain about labour being in short supply.”
So what explains the high number of job vacancies?
Morissette said for low-skilled industries, businesses may be choosing to keep wages low and accept higher vacancy rates.
“For employers that have negligible training costs, a human resource strategy that combines relatively low wages with high worker turnover and some vacancies might actually … maximize profits,” he said.
The federal government has kept an open ear to business groups raising alarm bells about labour shortages.
In the fall, Ottawa announced new immigration targets that would see the country welcome 500,000 immigrants annually by 2025. Immigration Minister Sean Fraser has touted the new plan as a solution to the country’s labour woes.
Canada has also experienced a surge in the number of temporary foreign workers brought into the country to help businesses fill vacant positions.
The apparent shortage of low-skilled workers could push policymakers to think that even more temporary workers are needed, but Stanford said that would be a “disastrous” conclusion to draw from the report.
Many economists have reservations about temporary foreign worker programs that they worry can suppress wages domestically, if used excessively.
“The goal of immigration policy should not be to solve the recruitment problems faced by low-wage employers, or any employers for that matter,” he said.

About half of Canada’s environment ministers skip meeting on biodiversity loss

More than half of the provinces’ ministers have skipped out on a meeting with the federal government and Indigenous leaders to discuss halting land and water loss in Canada.

More than half of the provinces’ ministers have skipped out on a meeting with the feds and Indigenous leaders to discuss halting land and water loss in Canada.
Environment ministers from Saskatchewan, British Columbia, Prince Edward Island, Nova Scotia and the Northwest Territories attended the meeting.
The other provinces and territories sent their deputy ministers.
The Liberal government is leading a 2030 biodiversity strategy to protect 30 per cent of land and water by 2030, but it will be a difficult target to reach without the help of provinces and territories.
The federal ministry of environment and climate change says they have a critical role to play because they have significant authority over land use.
At the end of 2022 almost 14 per cent of Canada’s land and freshwater and almost 15 per cent of marine areas and coastline were under some kind of conservation protection.
