The Canadian Long Range Plan 2020 for astronomy and astrophysics builds on Canadian research's previous success to extend Canada's role.
Why do astronomers believe there's dark matter when it cannot be directly detected? Let's look at the evidence, and see what dark matter's presence means for our universe.
Most people think that many millions of years ago, Saturn didn't have rings at all. Instead, it had a big moon moving around it. Eventually, the moon burst and broke into pieces.
Around the world and throughout history, we find remarkably similar constellations defined by disparate cultures, as well as strikingly similar narratives describing the relationships between them.
Although the rings of Saturn may look like a permanent fixture of the planet, they are ever-changing. New analyses of the rings reveal how and when they were made, from what and whether they'll last.
In an age when women were rarely allowed in observatories, Margaret Burbidge changed how we saw the stars.
Matt Agnew is on the hunt for love as star of the new Bachelor Australia series. But whoever he picks (and he already has, apparently) will have to compete with TESS. So who, or what, is TESS?
If you got too close to a black hole, it would suck you in and you'd never be able to escape, even if you were travelling at the speed of light.
This point of no return is called the event horizon.
A 100-metre-wide asteroid passed just 70,000km from Earth on Thursday, and we had little warning it was about to happen. What threat is posed by asteroids and how do we find them?
As more than a million people have indicated plans to partake in a citizen 'raid' on the famed Area 51 to 'see them aliens,' a scholar on the search for extraterrestrial life weighs in on the hype.
The short answer is yes, but it’s really, really difficult.
The first humans to land on the Moon, and the team that got them there, get all the glory. But what about the people who laid the foundation for this effort by mapping the Moon? Who were they?
On the 50th anniversary of man's historic moon landing, Pedro Duque remembers how every child wanted to be an astronaut in 1969.
Scientists spend years preparing for the two-minute window of a total solar eclipse.
For the first time scientists have located the home galaxy of a one-off fast radio burst. Here's how they did it – and what they learned about the galaxy.
A new podcast series from The Conversation exploring the last 50 years of space exploration and the 50 years to come.
It is always exciting to discover new planets beyond our Solar System. Now a planetary astrophysicist is using a star's chemistry to predict which ones are likely to host giant planets.
Astronomers have found the first observational evidence for a disc of material around a giant young planet at a distant star. It's a place they think moons can form.
Every day about 50 tons of rocks from space fall on Earth. An examination of these meteorites has inspired a new theory about how exactly these rocks formed.
The first 60 satellites from Elon Musk's planned low orbit internet network have lit up the skies. But with more planned, astronomers say the satellites could ruin their work.
