It's once again time for the Perseids, one of the best meteor showers of the year

Each August, Earth plows through a thick trail of debris left over from a passing comet. The result: A spectacular night of meteors lighting up the sky.

Be on the lookout for northern lights tonight

There’s been a flurry of activity on the sun over the past few days, which means we may get a chance to see a good display of the northern lights tonight.

While Canadians look at European heat wave in awe, we face our own climate challenges

As records are breaking across Europe, Canadians may think they’ve gotten off lucky this summer, particularly in light of the record-breaking heat wave in British Columbia last June. While we may have had fewer heat waves this year compared to the past few, it may just be a case of a late start.

European heat wave isn't a surprise — it's a warning of what inaction could mean for our future

Europe is living in a disaster movie. Unprecedented temperatures have killed more than 1,000 people, roads in France are under threat of melting, runways have been forced to shut down. But this shouldn't come as a surprise, since climatologists have been sounding the alarm for years.

Canadian astronomers champing at the bit for release of 1st images from James Webb telescope

On Tuesday, the most powerful telescope ever built will help humanity trace its roots back to the beginning of time. Or at least as far back as we’ve ever been able to see so far. And Canadian astronomers can't wait.

Electric-blue, shimmering clouds begin their annual appearance across Canada

Amazing. Beautiful. Superb. These are words many people use to describe one of the sky’s most beautiful displays: noctilucent clouds. And the time is right for Canadians to try to see them for themselves.

If you’re a morning person, there’s a treat in the sky before sunrise: five of the sky’s brightest planets all lined up among the stars.

Where are all the Black astronomers and physicists? Racism, isolation keeping many away

While Canada produces many talented astronomers, astrophysicists and physicists, few of them are Black. The question is: Why?

Are we in for a spectacular meteor shower? Astronomers aren't sure, but suggest looking up tonight

Astronomers are waiting to see if a normally quiet meteor shower puts on a show Monday night. There's a potential outburst from the tau Herculids, but the key word is "potential." 

How and when to view Sunday's total lunar eclipse

On Sunday night if the skies are clear, Canadians will be able to watch one of the most beautiful celestial events there is: a total lunar eclipse.
