Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
The theoretical reasons to expect it are compelling, but the technology required to detect it is unfathomable. All throughout our galaxy, millions of black holes of a variety of masses […]
There’s a lot left to understand, ponder, and investigate. And there always will be. For hundreds of thousands of years — nearly all of human history — we had no definitive answers to some of […]
From the right place at the right time, it’s a sight unlike any you’ll find on Earth. In our Solar System, any planet with moons has a chance for a solar […]
It’s perhaps the most famous thought experiment in all of physics, but is full of popular myths and misconceptions. One of the most bizarre ideas about the quantum Universe is […]
CERN’s bold new proposal has physicists confronting the biggest question of all: is building a new collider worth it? If you want to discover anything novel about the natural, physical […]
Without a little help from Einstein, we couldn’t have made this discovery. NASA’s Hubble Space Telescope, currently celebrating its 30th anniversary, still churns out novel discoveries. The Hubble eXtreme Deep […]
This year’s June solstice coincides with a new Moon and an annular solar eclipse. Here’s how rare it truly is. As the Earth orbits the Sun, it rotates on its axis. […]
You never know what you’re going to find when you look somewhere new for the first time. Approximately 4600 feet (1400 meters) underground, beneath the Italian mountain known as Gran Sasso, […]
One look at the uncertainties and the assumptions changes the story tremendously. Is there intelligent life out there in the Milky Way beyond our own Solar System? If so, how […]
The view from beyond Pluto is far enough from Earth that we can see the stars shift. NASA’s New Horizons, humanity’s first spacecraft to encounter Pluto, is more than 4.3 billion […]
Even physicists sometimes fall for these. For centuries, the laws of physics seemed completely deterministic. If you knew where every particle was, how fast it was moving, and what the forces […]
Too little breathing room, tear gas, and insufficient masks are a recipe for disaster. Police are worsening all three. Across the nation and the world, people of all skin colors are […]
Solid, liquid, and gas are the three everyone learns. Plasma is the fourth. But there are two more, and they’re fascinating. How many states of matter are there? When you […]
We’re looking back farther in time than ever before. Here’s what we’re finding. Even today, the Universe is forming enormous numbers of new stars: from various nebulae throughout our galaxy to […]
It happened 13.8 billion years ago, so why hasn’t the radiation all passed over us by now? For the past 13.8 billion years, our Universe has been expanding, cooling, and gravitating. […]
They said the “missing half” of the Universe’s matter was just found. But what they found barely makes a dent to the big picture. When we look up into the great […]
The origin of the 3rd element on the periodic table was one of the great cosmic mysteries. We just solved it. How did we form the elements that pervade the Universe […]
It’s not only about what’s happening right now. Things need to change for good. It could be your colleague, your coworker, your staff member, or your student. As the world mourns […]
Maybe 100% of stars don’t have planets, after all. When stars form in the Universe, they’re created in giant bursts. A stellar nursery in the Large Magellanic Cloud, a satellite galaxy […]
It’s not just about SpaceX and Starlink. What we’re deciding today will have a global impact for years and decades to come. For countless millennia, human beings have gazed up into […]
