Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
When you mix science with speculation, you get speculation. But the underlying science is still real. Whenever you hear the phrase, “it’s just a theory,” it should trigger alarm bells in […]
It could evolve, strengthen, decay, or not be alone. Our known Universe contains matter, radiation, and dark energy. While matter (both normal and dark) and radiation become less dense as […]
Going to smaller and smaller distance scales reveals more fundamental views of nature, which means if we can understand and describe the smallest scales, we can build our way to […]
The scientists, not the fossil fuel industry, were right all along. Back in 1990, the world’s top climate scientists convened to put together a report on the state of Earth’s climate. […]
And the one step we can take to show extraterrestrials we’re figuring it out. Every year, Earth’s meteor showers accomplish two important tasks. This composite photograph shows a large number of […]
The ‘final parsec problem’ is still a mystery for astronomers. When it comes to black holes in the Universe, we know there are at least two major types. There are […]
It peaks the nights of August 11–13, but it’s no longer the year’s most reliable meteor shower. Every year, beginning in mid-July, planet Earth commences passing through an enormous debris […]
At 35 light-years away, it’s also the 2nd coolest, 2nd widest planet ever found. Despite discovering more than 4000 exoplanets, most remain obscure. Although more than 4,000 confirmed exoplanets are known, […]
Even a small merger can trigger so much more than we realize. Practically every galaxy in the Universe has a supermassive black hole at their core. Ranging from millions to many […]
If we succeed in contacting them, will that seal humanity’s doom? One of the most wondrous questions of all concerns our place in the Universe. After 13.8 billion years of […]
And, if we have one, how close are we to it? No matter which direction we look in, or how far away our telescopes and instruments are capable of seeing, the […]
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 […]
Only the best physical theories outlast the minds that invented them. Throughout the 20th century, a number of discoveries revolutionized our Universe. The discovery of the interior structure of atoms as […]
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 […]
