Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
Hubble, our greatest space-based observatory today, is just the beginning. The Hubble Space Telescope has been astronomy’s most revolutionary observatory in history. The stars and galaxies we see today didn’t […]
Galaxies can have regions both hotter and colder than the background radiation of the Universe. When we talk about the depths of space, we get this picture in our heads […]
Theoretically, we know what happened on the red planet. Here’s how we’ll find out whether we’re right. When it comes to the worlds beyond Earth in our Solar System, it’s only […]
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 […]
