If you think we’ve seen all there is to see in the Universe, you’re about to have your imagination unlocked. “Hubble often takes images of distant gravitationally lensed galaxies to […]
The ELT, at 39 meters in diameter, will dwarf everything that’s ever come before. “There are so many people who are arguing or fighting over issues which don’t have much relevance. […]
Last week, Cassini plunged into Saturn’s atmosphere. Here are the top 6 things we learned from it while it was alive. “Being a scientist and staring immensity and eternity in the […]
While it’s fresh in everyone’s mind, this is the best time to turn awareness into action. “Hurricane Katrina overwhelmed levees and exploded the conventional wisdom about a shared American prosperity, exposing […]
Something’s got to be wrong. But is it what we think about the star, the Universe, or something else? “The older you get, the more you realize that the way […]
Just a few simple, common conditions can create the perfect storm. 80% of the time, humans are the trigger. “I’d rather fight 100 structure fires than a wildfire. With a structure […]
Many sci-fi technologies will remain in the realm of fiction unless physics changes. But some experiments could uncover just that! “Imagination makes us aware of limitless possibilities. How many of us […]
Earthquake? Nuclear explosion? Fission or fusion? We know, even if world leaders lie. “North Korea has taught a great lesson to all the countries in the world, especially the rogue countries […]
For the first time, the gravitational wave sky and the astronomical sky might be coming together. It’s a new era, at long last. “Presently thought to be the most powerful explosions […]
Did you experience totality? I did, for the first time. And it was, even as a well-prepared scientist, beyond anything I expected. “All that is nowAll that is goneAll that’s […]
A new podcast: a first-person account, by a scientist, of what it was like to live and experience totality for the first time. “I sometimes ask people, ‘Can you be aware […]
Want to be hotter? Add more mass. Want to go even hotter than that? Lose almost all of it. “A candidate is not going to suddenly change once they get into […]
When matter falls in, black holes grow. But Hawking radiation says that black holes decay. Who wins? “Maybe that is our mistake: maybe there are no particle positions and velocities, but […]
More than 90% of the eclipses to ever happen on Earth have already occurred. Don’t miss the next one! “We live in a moment of history where change is so speeded […]
It’s a great show in total darkness. Here’s how to not ruin it for yourself. “Yes, I am well aware that nature — or what we call nature: that totality of objects […]
No other object this large has come so close to Earth in millions of years. In the 5th millennium, we might suffer the consequences. “Honestly, if you’re given the choice […]

Oregon, Idaho, and Wyoming are all on fire, and simply driving your car can be the most dangerous thing of all. “I’d rather fight 100 structure fires than a wildfire. With […]
Gravitational waves and spacetime ripples have so much more to do with the Universe than just merging black holes. “The years of searching in the dark for a truth that one […]
If you know when, where and how to look, the show will still be spectacular. “My dad took me out to see a meteor shower when I was a little […]
Black holes shouldn’t be this big, much less this big so many billions of years ago. Yet here we are. “Ultramassive black holes — that is, black holes with masses exceeding 10 billion […]
The speed of light is a universal constant, but that doesn’t necessarily mean that light always travels at that speed, does it? “There was a young lady named Bright,Whose speed was […]
On August 21st, 2017, a total eclipse will hit 14 states. Here’s your guide to everything you need to know. “…and the Sun has perished out of heaven, and an […]
The greatest advances in human history have come from science and scientific knowledge. Don’t stop now. “Bad times have a scientific value. These are occasions a good learner would not miss.” […]
But there are resources, tips, and telltale signs to keep you from being duped. “Some people think that the truth can be hidden with a little cover-up and decoration. But as […]
The red planet is nearby, cool, sunny, and was once potentially habitable. Could it someday be that way again? “It would be great some day to have astronauts in a rover […]
From a Universe that went no bigger than our Milky Way to the trillions of galaxies in our expanding Universe, our knowledge increased one step at a time. “Gamow was fantastic […]
After a generation, we’re finally getting another close-up view. With the science we’re learning, we just might solve its mysteries. “Jupiter instead cooled down below the threshold for fusion, but […]
With quantum teleportation now occurring from Earth to satellites, how long is it before we can teleport a human being? “There would be no Star Trek unless there were transporter malfunctions.” –LeVar […]
Falling into a black hole is forever… but could a tether to the outside pull you back out? “Nobody ever did, or ever will, escape the consequences of his choices.” –Alfred A. […]
