The Leonid meteor shower peaks today. Its parent comet taught us where meteor showers come from. Every year, as Earth regularly orbits the Sun, meteor showers repeatedly recur. While August’s Perseids […]
There’s so much we don’t know about fast radio bursts and galactic halos. Combined, we get a unique window on the Universe. Deep in space, mysterious signals known as Fast […]
A vacuum cleaner is the wrong picture. Time to bust that myth. There are no classes of object in our Universe more extreme than black holes. With so much mass present […]
A new study has bad news for those who binge watch TV.
Imagine you had perfect technology and unlimited fuel. How far could you go? Human spaceflight has brought us beyond Earth, but we could potentially venture even farther. The very first launch […]
The future of food sounds bleak, but it doesn’t need to be this way.
Dr. Charles Grob was the first researcher granted FDA approval to study these drugs.
At 18 percent of the population, Hispanics account for 67.2 percent of U.S. net homeownership gains.
Recently, Tron appears to have been at the center of the latest fake news scandal to hit the crypto world. It started on July 8, after Twitter user Hayden Otto […]

The Sun will eventually become a red giant star, swallowing Mercury and Venus in the process. But what will happen to Earth? There are a few existential questions we can ask […]
She’s not a scientist, an expert, or even an adult. But she’s got one good lesson to teach us all. Like most people on Earth, Greta Thunberg is not a climate […]
Every object in the Universe is constrained by the laws of physics. Does this mean there are any black holes that shouldn’t exist? When it comes to the objects that […]
From explosions to their unique and vibrant colors, the fireworks displays we adore require quantum physics. This Thursday, July 4, 2019, is remarkable for a number of reasons. It happens to […]
After 13.8 billion years, there’s still a whole lot that’s changing as time goes on. With each new year that comes upon us, there are a slew of new events awaiting […]
If you’re wondering whether the blast wave or the radiation would kill us first, you’re asking the wrong question. As far as raw explosive power goes, no other cataclysm in […]
Less than a mile long, the Dorfbahn in Serfaus is also the world’s highest metro system.
An entire Universe of possibilities await stars like our own, even after they run out of fuel. One of the most profound rules in all the Universe is that nothing lasts […]
We’d never flown past or imaged a small, isolated Kuiper belt object before. Here’s what we know so far. As 2018 ended and 2019 began, NASA’s New Horizons flew past its […]
A black hole’s event horizon is thought of as the point of no return. But perhaps there are ways back out, after all. Black holes just might be the most extreme […]
Scientists actively researching this have known the answer for quite some time. It’s time for everyone to catch up. The Big Bang happened 13.8 billion years ago, and is generally regarded […]
Physicists sure do give counterintuitive names to the things they find. Most of us are confounded by the idea of relativity when we first encounter it. Objects don’t just move through […]
A star orbiting past our galaxy’s supermassive black hole offered a chance to test relativity as never before. The supermassive black hole at the center of the Milky Way is the […]
Despite warnings and protestations from astronomers and skywatchers, Starlink is moving fast and breaking things. In May of this year, Elon Musk’s SpaceX launched the first group of its new satellite […]
General Relativity had to be right. Here’s how we knew. What happens to light when it passes near a large mass? Does it simply continue in a straight line, undeflected from […]
The solar eclipse of May 29, 1919, was the nail in the coffin of a Newtonian Universe. On May 29, 1919, the world changed forever. For hundreds of years, Isaac […]
President Trump has called for Silicon Valley to develop digital precogs, but such systems raise efficacy concerns.
Here are four separate ways you can prove it, even 50 years after-the-fact. 50 years ago, on July 20, 1969, humanity took our first footsteps on the surface of another […]
