  • A total lunar eclipse will occur on January 20. 
  • This “super blood wolf moon” gets its name because the eclipse will occur when the moon is full (called a wolf moon in January) and closer to Earth than normal (a super-moon). The Earth’s shadow will make it appear reddish.
  • The lunar eclipse is slated to last one hour and two minutes.

On January 20, the Earth will pass between the sun and moon, block light from the sun and casting a shadow on the moon.

This is a total lunar eclipse, and it will be the last one we see until May 2021 (though there will be partial lunar eclipses before then). 

Total lunar eclipses are not that rare — the last one occurred in July 2018 — but this one stands out as a “super blood wolf moon.” 

That name is based on the eclipse’s timing and the moon’s position relative to Earth. Total lunar eclipses make the moon look orange-red because of the effect that Earth’s atmosphere has on the sunlight that passes through it, which is why they are often called blood moons. Full moons that occur in in January are known as “wolf moons” (each month gets its own full-moon name), and this one will appear especially bright and big because the moon will be a little closer to Earth than normal — hence the label “super.”

The total lunar eclipse will be fully visible to people in North America, South America, Greenland, Iceland, western Europe, and Africa. People in other parts of the world will see a partial eclipse.

According to NASA, the total lunar eclipse will last one hour and two minutes. For those on the US East Coast, the total eclipse will begin around 11:41 p.m. local time with a peak at 12:16 a.m.  

During a lunar eclipse, the moon first touches Earth’s outer shadow, called a penumbra, then moves into the full shadow, called the umbra. It then goes back into the penumbra.

About 80% of Earth’s atmosphere is nitrogen gas, and the rest is mostly oxygen. After our atmosphere takes in white sunlight, that gas mixture scatters around blue and purple colors, which is why the sky appears blue to our eyes during the day. 

During a lunar eclipse, Earth’s atmosphere scatters blue light and refracts the red — a process similar to what we see during sunrise and sunset. That’s why the moon appears to turn red when in Earth’s umbra.

Watching a total lunar eclipse is not dangerous — unlike looking at a solar eclipse without protection — so you don’t need any special glasses.

A big test of reusable packaging for groceries comes to Canada

Editor

Published

An online store has launched in Ontario selling groceries and household items from Loblaws in containers it will take back and refill — a test of whether Canadian consumers are ready to change their habits. Industry-watchers say it is breaking ground for reusable packaging.

The store, called Loop, launched in Canada on Feb. 1, in partnership with supermarket giant Loblaws, and offers items like milk, oats, ice cream and toothpaste for delivery in most of Ontario. Loop is already operating in the continental U.S., the U.K and France. 

Included so far are some products from well-known brands such as PC sauces and oils, Häagen-Dazs ice cream, Heinz ketchup, Chipits chocolate chips and Ocean Spray cranberries. 

“The goal is really validating that this is something the Canadian public is interested in,” said Tom Szaky, founder and CEO of Loop and its parent company TerraCycle.

Unlike existing small no-waste retailers, they want to offer “your favourite product at your favourite retailer in a reusable and convenient manner.”

The involvement of a huge retailer makes the launch notable in terms of scale and who it will reach, said Tima Bansal, Canada Research Chair in business sustainability at Western University in London, Ont. 

“I think it’s at the scale that’s needed to create the change in the community in Canada more generally,” she said.

How it works for customers

Szaky likens Loop to the reusable bottle system for beer in Canada “but expanding it to any product that wants to play in the [North American] ecosystem.”

The ultimate goal, he said, is to give people a greener way to consume that limits the amount of mining and farming needed to produce packaging.

“This allows us to greatly reduce the need to extract new materials, which is the biggest drain on our environment.

Loopstore.ca currently lists just 98 products, although many are sold out or “coming soon.” 

As with other online grocery stores, customers fill their virtual shopping cart, but in addition to the cost of the item itself, they pay a deposit for its container. That can range from 50 cents for glass President’s Choice salsa jars like the ones that are normally at the supermarket to $5 for a stainless steel Häagen-Dazs ice cream tub. 

The items are delivered to a customer’s home by courier FedEx for a $25 fee, although the fee is waived for orders over $50.

Once you’ve spooned out all the salsa or ice cream or squeezed out all the toothpaste, the container doesn’t go in the recycling bin. Instead, you toss them into the tote bag they came in — even if they’re dented or damaged — and they get picked up.

This wearable device beeps when workers get too close to each other

It’s a device that emits a high-pitched beep, buzzes and lights up if your coworker steps too close.

While some introverts would have bought this device before the pandemic to stave off chatty colleagues near the coffee machine, ZeroKey designed the product with a more important purpose — helping employees physically distance to reduce the risk of spreading coronavirus. 

The Calgary tech company’s “Safe Space” device looks like a small plastic badge that can be worn on a wrist or clipped to a shirt pocket or belt. 

“Our products, in a nutshell, localize or figure out where things are in 3D space and our big claim to fame is we do it very precisely, more precisely than anyone else in the world,” said Matt Lowe, co-founder and CEO of ZeroKey.

The company says its location-tracking technology passively monitors the distance between each device and is accurate down to 1.5 millimetres. The distance on devices can be set — so if, say, science determines three metres apart is actually safer that two, that can be tweaked. 

Lowe says the company came from humble beginnings — he and a co-founder, working out of a room in his house. The company has grown from two to 30 employees and has more openings it’s looking to fill.

Inspired by sci-fi

Their inspiration comes, as so many technological innovations have, from sci-fi. 

Lowe recalls watching Minority Report, and being transfixed with the gesture-based user interface Tom Cruise’s character operates. 

“Wouldn’t it be awesome if we had an interface that was more in tune with how humans operate naturally with their hands. So if you could just walk up to a new piece of technology … and just immediately be proficient,” he said. 

But applying that tech to the COVID-19 era wasn’t something the company had anticipated.

Lowe said some of the company’s clients in the manufacturing industry approached ZeroKey with a request.

“They came to us and said, ‘hey … we have the data where people are, can you build some sort of system so that we can do contact tracing and we can let people know if they’re closer than two metres?’ And we said, ‘absolutely … that’s easier than what we normally do,'” he said.

Blistering rallies spur Canadian tech world to repeat equity sales

Editor

Canadian technology companies have been making multiple trips to the equity market over the past year, capitalizing on a rally in tech shares that’s helping them raise cash at ever higher valuations.

Dye & Durham Ltd., which makes software used by law firms, took advantage of a more than sixfold rally in its shares since its July IPO to raise $500 million (US$394 million) in a bought deal of stock and convertible debentures, the company said Tuesday. Dye & Durham, which went public at $7.50 a share, received $50.50 per share in the private placement. Peers including Lightspeed POS Inc. and Docebo Inc. have made similar moves.

Shares of technology companies have gained since the onset of the pandemic as their corporate customers increasingly turned to cloud-based applications to support their remote workforces, said Anurag Rana, an analyst at Bloomberg Intelligence. The technology sector was one of the few places investors could look for growth during the crisis, with huge swaths of the economy including retailers, restaurants, airlines, hotels and casinos hammered by lockdowns, he said.

“Issuers and private-equity investors are not stupid, and they know somewhere down the road that valuations may come back,” Rana said. “So this is the time when they sell.”

Canada’s S&P/TSX Information Technology Index has risen 82 per cent in the past year, fuelled by rallies in Lightspeed and Shopify Inc. That compares with a 36 per cent advance for the U.S. S&P 500 Information Technology Index.

Those gains are giving early investors in tech companies an opportunity to take some profits. In conjunction with Dye & Durham’s private deal announced Tuesday, some investors agreed with the underwriters to sell 1.98 million shares at the $50.50 price as well.

Lightspeed, which provides cloud-based point-of-sale systems for retailers and restaurants, has also seized the moment. The company went public in Canada in February 2019 and last year followed that up with a U.S. IPO, selling shares for US$30.50 apiece. The deal raised US$332.3 million for the company and US$65.4 million for some shareholders.

After Lightspeed’s share price more than doubled, it went back to the market again last week with a public offering of shares for US$70 each, raising US$620.2 million for the company and US$56 million for other shareholders.

Docebo, which sells cloud-based learning software, has tapped the market multiple times over the past year. The firm, which went public in Canada in October 2019, completed a bought deal of shares atC$50 apiece in August. The move raised $25 million for the company and $50 million for investors including founder and Chief Executive Officer Claudio Erba, Chief Revenue Officer Alessio Artuffo and top outside investor Intercap Equity Inc.
