Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
NASA’s SOFIA mission is upgraded and back in action, and the Cigar Galaxy makes a perfect target. In theory, cold, neutral gas is the key to stars and galaxies. A visualization […]
Being a small piece of a large experiment is vital to the enterprise of science. Have you ever wondered what it’s like to work as a small (but vital) part of […]
The inevitable long, slow decline is accelerating, and there’s nothing we can do. The Universe, as it is today, is less active, is forming fewer stars, and is creating fewer chances […]
Science was never the same after meeting ‘the particle who lived.’ Back in the early 1930s, there were only a few known fundamental particles that made up the Universe. If you […]
Thou shalt not conclude “aliens” from insufficient data. When it comes to what’s out there in this Universe, perhaps the only thing that’s greater than our cosmic ignorance is the […]
Just say no to artist’s illustrations. This is what the Universe actually looks like. The Universe we observe often surpasses our greatest imaginings. This 20-year time-lapse of stars near the center […]
Avi Loeb says it’s aliens. Every other astronomer disagrees. Here’s why. In 2017, an astronomical event occurred that was unlike any other: for the first time, we observed an object that […]
Think there are habitable super-Earths out there? Think again. Here in our Solar System, we have two very distinct types of planets: small, terrestrial, rocky worlds, with thin (or no) atmospheres […]
There’s a lot to get rid of if we want to get only our Universe out of String Theory. A lot of people, when they learn about String Theory for the […]
And after years of mystery, we finally know where they come from. Here on Earth, thunderstorms and accompanying lightning strikes represent tremendous releases of energy. It was way back in 2011 […]
Time always moves in the same direction, but what if the Universe were contracting? As we step forward in time, a number of things always seem to happen together. Objects […]
It’s not a gambit. It’s not fraud. It’s not an opinion. And it’s not biased like you think it is. Most of us, when we think about what science is, default […]
What we’ve seen isn’t necessarily what we get, but the most common world doesn’t look like ours. There’s a very common myth out there in astronomy: the idea that the Sun […]
The night sky is already noticeably different, and bigger changes are ahead. For all of human history until the launch of Sputnik, the only objects in the night sky were naturally […]
A new survey, the DESI Legacy Imaging Survey, has found more lenses than all others put together. One of Einstein’s most revolutionary predictions is that mass bends light. During a […]
We have two ways of measuring the expansion rate. Here’s the harder one. If you want to understand where our Universe came from and where it’s going, you need to measure […]
The newest record-setting quasar houses an enormous black hole. No one knows how. In every scientific field, we’re always on the lookout for whatever new discovery might reveal what’s currently beyond […]
Binary pulsars are doing what no other measurement has done: measure our galactic acceleration directly. Even though the majority of the matter that makes up our Universe may be completely […]
If you thought it was just one rich region in space, look deeper and wider. Shining brilliantly in January’s skies is the Great Orion Nebula. By 10 PM every night in […]
And can we devise an experiment to tell, even when we aren’t looking? One of the most bizarre aspects of quantum physics is that the fundamental entities that make up the […]
