Need more astronomical phenomena in your life? We’ve got you covered. 

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 […]

Elegance, beauty, and mathematical precision makes for a compelling story and an exquisite model. But it doesn’t make it right. Scientific theories, at their best, are simple, straightforward, full of predictive […]

A study finds how hits from giant meteorites during Earth’s early days impacted plate tectonics and the planet’s magnetic field.

In the far future, the last star burns out, stellar corpses get violently ejected, and galaxies accelerate away. And then the fun begins. For centuries, the biggest questions about our Universe […]

It isn’t about saving us from aliens at all. “To be on my very first spacewalk, to be outside, and to have contamination in my suit to the point that I […]

LISA, the Laser Interferometer Space Antenna, will not only be the space-based successor to LIGO, but will predict black hole mergers up to years in advance. Across the Universe, innumerable masses […]

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.” […]

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 […]

What if we build from the sky down? NYC architects release designs for a skyscraper that would hang from an asteroid and travel between hemispheres.

It isn’t the rapture or some crazy prophesy, but science, that tells us when and how the end will come. “The surface of the Earth is the shore of the cosmic […]

Aiming for the nearest star would necessitate a whole slew of advances. Even if the mission fails, humanity wins by investing in itself. There have been some magnificent moments in NASA […]

Career global security expert Richard Clarke identifies three potential game changing events that could adversely affect the wellbeing of humanity itself.

The truth might not be ‘out there’ at all. There may never have been another intelligent, technologically advanced alien species in the entire history of the Universe. When you take into […]

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 […]

New research explains how to build different types of outposts in space.

What if alien life — or even intelligence — don’t look like what we’re searching for? When the original Star Trek premiered, it was revolutionary for depicting sentient, intelligent species other than humans, living […]

NASA scientists are sifting through some of the last transmissions from Cassini. And what they’re finding are kittens. You read that right.

Out of five vital questions, which one should we most desire the answer to? Despite all we’ve learned about physics, science, and the Universe before us, there are still some incredibly […]

Last week, an asteroid fell from the sky and struck the Lake Michigan area. What if it had been a city-killer instead? “By preventing dangerous asteroid strikes, we can save […]

An eruption from a supervolcano could be catastrophic. Here’s NASA’s plan and how sensible it is.   

This mission will also help us better understand the core of our and other terrestrial planets, too.   

Why do the asteroids that fall to Earth have the composition they do? A giant space collision 466 million years ago may be to blame. “Men of genius are often dull […]

Astrobiologist Lewis Dartnell explains why we shouldn’t be afraid of alien visitors.

Phobos and Deimos may have had another, inner, much larger companion! “The larger inner moons fall back to Mars after about 5 million years due to the tidal pull of […]

Global security expert Richard A. Clarke explains the traits of a “Cassandra”—someone who predicts colossal disasters—and why people very rarely listen to their warnings.

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 […]

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, […]

The results of this study help us better understand how stars are born and how they develop.  

We take for granted how much the Moon does for Earth, but not all of the changes would be bad. “If we get rid of the moon, women, those menstrual cycles […]
