The largest moon in our Solar System, often overlooked, is a water-rich world. Does that mean life? Here on Earth, life took hold very early on in our planet’s history, and […]

We just observed the first ‘lunar formation’ in an exoplanetary system. This one image, above, is the first to show moons actively forming around a planet. This colourful image shows […]

Most of us will never run a 4 minute mile. But on a bicycle, almost anyone can do it. As human beings, we often take for granted how our bodies work. […]

Despite the recent headlines, it’s an extraordinarily unlikely proposition. Have you ever wondered, if it were possible to travel through space straight ahead as quickly as you could imagine, if […]

Hubble’s still going strong after 31+ years. James Webb will never make it that long. Every decision that’s made — in both astronomy and in life — comes with its own set of pros and […]

50% of stars are in Sun-like ‘singlet’ systems. The planetary nebulae we see just don’t line up. Around 7 billion years from now, our Sun’s life will end. As the Sun […]

Ignoring a scientific truth doesn’t change it, even when the consequences are deadly. “If all your friends jumped off a bridge, would you do it, too?” Many of us, as children, […]

And why, even at its faintest, it always outshines every other star and planet. If you’ve been looking to the west after sunset recently, you may have noticed that there’s one […]

If our nearest star has an Earth-like planet, here’s how we’ll see it. As seen from up close, the signs of not only life, but our intelligent, technologically advanced human civilization […]

Hidden variables aren’t ruled out, but they can’t get rid of quantum weirdness. Ever since the discovery of the bizarre behavior of quantum systems, we’ve been forced to reckon with […]

Over the coming decades, over 100,000 new satellites are expected. For countless millennia, whenever we were faced with a clear, cloudless, moonless night, all of humanity was able to witness […]

The dream of zero resistance is closer than you may think. One of the biggest physical problems in modern society is resistance. Not political or social resistance, mind you, but electrical […]

Yes, the Big Bang is real, but what about what came before? If you ask anyone about the origin of some phenomenon that we’ve observed, they’ll usually default to the same […]

The rarest stars in the Universe are the ones we need the most to make humanity possible. Like everything in the Universe, stars are born, they live a little while, […]

When you view your right hand in a mirror, it appears as a left hand. Writing is reversed, as is the direction of any spinning object: clockwise becomes counterclockwise and […]

Planets are either rocky, like Earth, or gas-rich, like Neptune, with no in-between. What are the different types of planets that exist in the Universe? If all you could see […]

An almost 40-year-old theory finally has ‘smoking gun’ evidence for it. During most of their lives, stars burn stably, changing imperceptibly. The rotten egg nebula, at lower right (and shown in […]

Whether they’re gas giants or rocky planets makes all the difference for life. Over the past 30 years, we went from not knowing if there were planets like ours around other […]

Metal really does sometimes stick to some people’s skin. Here’s the science of why. Every once in a while, a claim comes along that wildly challenges the mainstream scientific narrative. These […]

Despite all the challenges, Hubble has vindicated this discovery. Practically everywhere we look in the Universe, the large-scale objects that we see — small galaxies, large galaxies, groups and clusters of galaxies, […]
