Don't let the simple graphics fool you: NASA's Comet Quest is a complex and addictive online game that challenges you to perform several missions, including landing, collecting and transmitting scientific data, and keeping Rosetta safe from chunks of comet material that occasionally spews from the surface. » 11/13/14 6:20am 11/13/14 6:20am

This Is What A Speck Of Space Dust Actually Looks Like

Using a specialized facility at the Ames research center, NASA scientists have successfully recreated the cosmic grains that permeate the galaxy and form all planets. Perhaps surprisingly, star-stuff is actually quite complicated. » 5/08/14 2:11pm 5/08/14 2:11pm

Watch The Most Detailed Simulation Of the Universe Ever Created

This simulation — the most detailed look at the structure of the universe yet — carries us through over 13 billion years in the life of the universe (picking up just under half a billion years after the Big Bang) in just two minutes. » 5/07/14 12:50pm 5/07/14 12:50pm

Watch This Terrifying Recreation Of The Deadly Oso Mud Slide

In late March, a major landslide occurred a few miles east of Oso, Washington, killing at least 35 people and engulfing an area approximately one square mile (2.6 km2). Geologists are now studying the event and they're baffled by its ferocity and speed — a slide that rushed down at an astounding 60 mph (97 km/hr). » 4/10/14 1:50pm 4/10/14 1:50pm

This Could Be the First Animal to Live Entirely Inside a Computer

Animals are exceptionally complicated things. So complicated, in fact, that we've never actually built one ourselves. But the day is fast approaching when we'll be able to create digital versions of organisms on a computer — from the way they move right through to their behaviors. Here's how we'll do it. » 4/10/14 11:30am 4/10/14 11:30am

Here is your first look at the atomic structure of the HIV capsid

Today's comment of the day comes to us from commenter Ryan M, who responded to our call for the most incredible images of 2013 with a nominee from something that he's been working on: The first look at the atomic structure of the HIV capsid. » 12/18/13 4:30pm 12/18/13 4:30pm

Our algorithms can predict future earthquakes -- now what?

New sensor technologies and computer algorithms that allow us to predict earthquakes, floods and famines before they happen. So now we're safe, right? Wrong. The big question is how we'll use this information, and whether we can warn people in time. » 5/13/13 12:20pm 5/13/13 12:20pm

This physics simulation is one of the most accurate you'll ever see

Physicists from Berkeley say they've figured out the insanely complex math behind the way bubbles pop when they're in a foam — and they've got an extraordinarily accurate video to prove it. » 5/13/13 11:23am 5/13/13 11:23am

Can evolution still happen without competition?

A new theory proposed by two computer scientists suggests that animals can still experience significant evolutionary changes over time, even in the absence of selectional pressures. » 4/29/13 8:00am 4/29/13 8:00am

Choosing the virtual reality experience that’s right for you

We're still several decades away from developing completely immersive computer simulations, but it's not too early to dream about the ways we'll be able to use them. Today we're exploring the tremendous potential with new gadgets like Glass, Google's computer glasses. But that's just the beginning. » 7/11/12 4:00pm 7/11/12 4:00pm

New simulation is as close to traveling through space as it gets

SpaceEngine is a free space simulation program that allows you to travel through intergalactic space in three dimensions. Starting from Earth, you can journey out into the cosmos and visit all known areas of the Universe. And as for those places where no one has gone before, the computer can simulate that experience… » 7/10/12 4:40pm 7/10/12 4:40pm

3 Computer Simulations that Changed The World (And 2 That Are on the…

Computer simulations have already massively transformed our ability to study complicated situations and events. We can study the effects of disasters without having to suffer through the real thing, and we can test out solutions. Running simulated events on powerful computers, based on real-life factors, lets… » 7/06/12 12:15pm 7/06/12 12:15pm

Supercomputer simulates nuclear explosion down to the molecular level

Treaties forbid the detonation of nuclear test weapons — which creates problems for national defense developers who need to efficiently certify the effectiveness of their arsenal. Luckily for them, a powerful new supercomputer is now able to replicate the physical impact of nuclear explosions — albeit digitally. And… » 6/06/12 4:30pm 6/06/12 4:30pm
