Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
There’s a million things we haven’t done. But just you wait. The Universe as we know it began some 13.8 billion years ago with the onset of the hot Big Bang. […]
On the largest scales, dark matter holds the Universe together. But on small ones, it helps reveal exactly what it is… and isn’t! Dark matter is often thought of as the […]
All the things that surround us and make us up weren’t always here. But where did it all come from? The Universe, as we see it today, sure is full of […]
We all share atoms with every person, living or dead, on Earth. There’s more in common among us than you might think. When you eat food, drink liquids, or even breathe […]
A generation ago, NASA launched their great observatories to explore the Universe. It’s time for round 2. Throughout the history of astronomy, every advance we’ve ever made has come about because […]
It’s 100 years since astronomy’s famous ‘great debate.’ We still haven’t learned the most compelling lesson of all. So, you’ve arrived at a crossroads: you think the world works in a […]
In both visible light and infrared, we get a preview of the spectacular advances that await the James Webb Space Telescope. What astronomers see isn’t just determined by the telescope […]
Visiting even one friend can undo all the good work that social distancing has accomplished. Over the past few months, people all over the world have come to realize just […]
Over the past 30 years, we’ve revolutionized what we know about the Universe. But we couldn’t have done it without these lessons. On April 24, 1990, the Hubble Space Telescope rocketed […]
Its record-holding galaxy is 32 billion light-years away, in a Universe that’s only 13.8 billion years old. On April 24, 2020, humanity celebrates the 30th anniversary of NASA’s Hubble Space Telescope. […]
We might live in a quantum Universe, but we’ll violate the principle of relativity if space is discrete. If you try and divide matter into smaller and smaller chunks, you’ll […]
How does one supernova get so bright, so energetic, and so massive? It’s a spectacular mystery to solve. On February 22, 2016, one of humanity’s automated sky-scanning telescopes — the Pan-STARRS Survey for […]
The original Hubble Deep Field truly showed us what the Universe looks like. Later this month, the Hubble Space Telescope will celebrate its 30th anniversary. This photo of the Hubble Space […]
When you look at the Universe in an entirely new way, you sometimes find what you could never have anticipated. Almost exactly one year ago today, the Event Horizon Telescope […]
All stars will eventually die. But we’ve never seen ones die like this before. When you look up at the sky, most of the points of light we see appear to […]
Astrophysics has probed a test of a fundamental law, ‘Lorentz invariance,’ well beyond the LHC’s limits. Einstein is still right. The greatest scientific legacy that Albert Einstein left us is this: […]
Your opinions about a large number of complex scientific issues are probably wrong. That’s why we have science. In 2016, an Italian virologist named Roberto Burioni was invited to appear on […]
We’re not made out of the densest elements, but we’re the densest planet nonetheless. Here’s why. Of all the planets, dwarf planets, moons, asteroids and more in the Solar System, only […]
The center of our Sun tops out at 15 million K, but nuclear bombs can get nearly 20 times hotter. Here’s how. In terms of raw energy output, nothing on our […]
Ending social distancing won’t only make us sicker, but will tank the health care industry in the process. The COVID-19 coronavirus pandemic continues to spread around the world. As of today, […]
