65 million years, an impact wiped out 30% of all life on Earth. Could another one be imminent? “That which can be asserted without evidence, can be dismissed without evidence.” […]

If atmospheric hazes can cool the distant ice dwarf by an extra 30 degrees Celsius, maybe we can geoengineer a solution to our warming problem? When NASA’s New Horizons flew by […]
NASA scientists are sifting through some of the last transmissions from Cassini. And what they’re finding are kittens. You read that right.
Could there be a massive, giant planet beyond Neptune? Here’s what the science says… for now. “Finding out that something you have just discovered is considered all but impossible is one […]
The ‘big discovery’ is nothing of the kind. We need a new planet-finding mission to probe the next frontier. Last week, NASA dropped a bombshell that it’s Kepler mission — the greatest […]
New research on Uranus’ magnetosphere could help scientists learn about distant systems, and refine the ways they search for alien life.
Before we go venturing off to another star to look for life, why not look here? “If I had to describe myself to an alien I’d say I was bigger than […]
Earth is pretty much the limit of how large you can get and still be rocky. Anything much larger, and you’re a gas giant. “How vast those Orbs must be, and […]
It’s discovered thousands. But how many more are out there? “How vast those Orbs must be, and how inconsiderable this Earth, the Theatre upon which all our mighty Designs, all our […]
This isn’t an XZibit joke; it’s a real scientific question. And the answer may be that it’s possible after all. “People who work every day are kind of scared of things […]
If it was good enough for more than 75 years, why not once again? “The cosmic game changed forever in 1992. Before then, logic told us that there had to be […]
The results of this study help us better understand how stars are born and how they develop.
But that’s okay; the most likely world for life may not be like Earth, after all. “You can spend too much time wondering which of identical twins is the more alike.” […]
Unpredictable winters? Seasons that don’t line up? It’s possible with the right configuration, says physics. “Lord of Light! Come to us in our darkness. We offer you these false gods. Take […]
With five moons orbiting it, Pluto is the richest rocky world known to date. How did it get that way? “We really expect the mission to be transformational. This is the […]
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 […]
The reports that our Solar System is missing the galaxy’s most common type of planet are greatly exaggerated. “To raise new questions, new possibilities, to regard old problems from a […]
There’s a lot to learn about other worlds, but you can’t learn it all without looking up. “One should not need a teleportation device to decide whether a newly discovered object […]
A very small person asks a very big question: why aren’t the moons of gaseous planets also made of gas?

More massive is bigger, less massive is smaller, right? That’s not even half the story. “Billions of years from now our sun, then a distended red giant star, will have reduced […]
It might be the nearest supernova humanity will ever see. What will happen when it goes off? “Without these supernova explosions, there are no mist-covered swamps, computer chips, trilobites, Mozart or […]
The 20th century held some incredible advances across all the science. But astrophysics’ best days are yet to come. “When we have found how the nucleus of atoms is built up […]
That’s not how probability works. Or asteroids, for that matter. “Bringing an asteroid back to Earth? What’s that have to do with space exploration? If we were moving outward from there, […]
Have you heard that life is unlikely around low-mass, red dwarf stars? It might be time to rethink that flawed conclusion. “Laws of nature mixed with evolutionary/historical contingencies allow for […]
The Earth is round, Kyrie Irving. But not every world needs to be. “‘I’ll follow him to the ends of the earth,’ she sobbed. Yes, darling. But the earth doesn’t have […]
A small, icy planet with a weirdly elliptical orbit has been discovered beyond Pluto.
The answer lies billions of years in the past. “Dark matter or invisible element?You decide.” –Toba Beta When we look out at the luminous matter in the Universe — stars, galaxies, clusters of […]
Something isn’t right about the Universe without something extra. So why can’t scientists agree on what that “extra” thing is? “All we know so far is what doesn’t work.” –Richard Feynman […]
If you thought the Kuiper belt was just icy worlds of various sizes orbiting like Pluto, think again. “There have only been two true planets discovered since ancient times, and this […]
Combined with Hubble, it creates our longest-baseline view. “It used to be that Pluto was a misfit. Now it turns out that Earth is the misfit. Most planets in the […]
