Canadian scientists discover ancient continent was larger than we thought – The Loop

Published

on


Geologists in Canada have found that an ancient continent was 10 per cent larger than previously estimated after analyzing rock samples dug up during diamond exploration work.

Researchers from the University of British Columbia (UBC) made the chance discovery while studying diamond samples from Baffin Island, the largest island in Canada.

They identified a new part of an ancient fragment of the earth’s crust known as the North Atlantic Craton, which ran from Scotland to North America and broke up 150 million years ago.

The scientists said the samples they analyzed had a “mineral signature” displayed in other parts of this particular craton, a large block of the earth’s crust that forms the nucleus of a continent.

Maya Kopylova, a geologist at UBC and the lead author of the research, said in a statement: “The mineral composition of other portions of the North Atlantic craton is so unique there was no mistaking it.”

She added that neighboring ancient cratons in Northern Canada showed different mineralogies and that her team’s discovery was “like finding a missing piece of a puzzle.”

The samples of kimberlite, an igneous rock which sometimes contains diamonds, came from deep beneath Chidliak Kimberlite Province in southern Baffin Island.

While previous estimates of the size and locations of the earth’s plates were based on relatively shallow samples taken from up to 10 km below ground, this study examined rocks extracted from a depth of 200 km.

The findings are published in the Journal of Petrology.

PHOTOS: Here are some of Kelowna's best photos of last night's Pink Full Moon – KelownaNow

Published

Last night’s Pink Full Moon was a hit, with people across the Okanagan and beyond capturing the sight on camera.

The full moon was also a supermoon – the brightest supermoon of the year – making it an even more exciting celestial event.

Here are just a few of the photos that Kelowna residents shared with us!

ISS Crew Blasts Off From Russia's Baikonur Cosmodrome Despite Virus-Hit Build-Up – The Moscow Times

Published

on


A three-man crew docked successfully at the International Space Station Thursday, leaving behind a planet overwhelmed by the coronavirus pandemic.

Russian space agency Roscosmos said the Soyuz MS-16 capsule “docked successfully” in a statement on its website.

Anatoly Ivanishin and Ivan Vagner of Roscosmos and NASA’s Chris Cassidy reached the ISS at 1413 GMT, just over six hours after blasting off from the Baikonur Cosmodrome, where COVID-19 caused changes to pre-launch protocol.

Usually the departing crew faces questions from a large press pack before being waved off by family and friends.

Neither was possible this time round because of travel restrictions imposed over the virus, although the crew did respond to emailed questions from journalists in a Wednesday press conference.

Cassidy, 50, admitted the crew had been affected by their families not being unable to be in Baikonur, Russia’s space hub in neighboring Kazakhstan, for their blastoff to the ISS. 

“But we understand that the whole world is also impacted by the same crisis,” Cassidy said. 

Astronauts routinely go into quarantine ahead of space missions and give a final press conference at Baikonur from behind a glass wall to protect them from infection.

That process began even earlier than usual last month as the trio and their reserve crew hunkered down in Russia’s Star City training centre outside Moscow, eschewing traditional pre-launch rituals and visits to the capital.  

The next crew to return to Earth from the ISS will be flying to their home countries on April 17 via Baikonur, rather than Karaganda in central Kazakhstan as usual, as part of new travel measures related to the pandemic. 

Tips on self-isolation

The ISS typically carries up to six people at a time and has a livable space of 388 cubic meters (13,700 cubic feet) — larger than a six-bedroom house according to NASA.

Those dimensions will sound enviable to many residents of Earth, more than half of whom are on various forms of lockdown as governments respond to Covid-19 with drastic measures.

In recent weeks, astronauts and cosmonauts on the ISS and on Earth have been sharing tips on coping with self-isolation.

In a piece for the New York Times last month, NASA’s Scott Kelly said his biggest miss during almost a year in space was nature — “the color green, the smell of fresh dirt and the feel of warm sun on my face.”

During his time aboard the ISS he “binge-watched ‘Game of Thrones’ — twice” and enjoyed frequent movie nights with crewmates, he wrote. 

Two-time cosmonaut Sergey Ryazanskiy has become the face of a 10-week challenge that will see participants post videos of themselves completing physical exercises as part of a competition aimed at both youth and adults. 

The initiative that Roscosmos is backing aims “to support people in a situation of isolation, instil a healthy lifestyle and thoughts through regular sports, without going out in public places,” Ryazanskiy said in a video promoting the “Cosmos Training” challenge.

The launch of Ivanishin, Vagner and Cassidy marks the first time a manned mission has used a Soyuz-2.1a booster to reach orbit, after Roscosmos stopped using the Soyuz-FG rocket last year. 

The newer boosters have been used in unmanned launches since 2004. 

The upgraded rocket relies on a digital flight control system rather than the analogue equipment used in prior Soyuz models.

Russia and Baikonur have enjoyed a near decade-long monopoly on manned missions to the ISS since NASA wound up its Space Shuttle program in 2011. 

But that may change as early as next month when Elon Musk’s SpaceX could be ready to launch a two-man crew to the orbital lab, NASA said in March. 

NASA said that the tech entrepreneur’s company and the space agency are targeting “mid-to-late May” for a test launch that will transport NASA astronauts Bob Behnken and Doug Hurley to the ISS in SpaceX’s Crew Dragon capsule. 

The International Space Station — a rare example of cooperation between Russia and the West — has been orbiting Earth at about 28,000 kilometers per hour (17,000 miles per hour) since 1998.

Tuesday's super pink moon lit up the Okanagan night sky – Kelowna News – Castanet.net

Published

on


If you’ve had your fill of COVID-19 news for the time being the moon put on quite a show last night.

This photo sent to us by Dale Sitar shows the super pink moon in all its glory Tuesday night.

Tuesday’s full moon was the biggest, brightest supermoon of 2020 and the second of three supermoons this year. April’s supermoon came the closest to our planet – and thus appeared the largest. 

Turns out we are currently in the midst of a series of supermoons according to the Old Farmer’s Almanac, the first happened on March 9, April’s was Tuesday night and the last occurs on May 7, 2020.

April’s full moon is called the “Pink Moon” as it’s the first to occur after the March equinox and heralds the appearance of the “moss pink,” or wild creeping phlox—one of the early spring flowers.

Historically, full moon names were used to track the seasons and, for this reason, often relate closely to nature. The moon names that we use today stem from Native American and Colonial-era sources. Traditionally, each full moon name was applied to the entire lunar month in which it occurred, rather than just the full moon itself.
