Check Out Crash Course Astronomy, A New YouTube Series From Phil Plait

Throughout the year, as Earth progresses through its orbit around the sun, one can witness stars in the night sky rise and set at different times. It's an example of an astronomical cycle visible to the naked eye, and the first of three subjects in Episode 3 of Crash Course Astronomy, a new series by Bad Astronomy's… » 1/30/15 8:00pm 1/30/15 8:00pm

Sorry conspiracy theorists, but the snow in Atlanta was real.

A conspiracy theory is floating around that someone other than Mother Nature is responsible for Atlanta's latest snowfall, spurred on by clips of people burning snowballs black. This video, using a lighter and some snow, explains why they're wrong — and explores the phenomenon of "snow that doesn't melt." » 2/03/14 7:00pm 2/03/14 7:00pm

This is the nerdiest collection of insults ever and it is the best

The labcoat-wearing brain child of SMBC's Zach Weiner, Bad Astronomy's Phil Plait and illustrator Jess Fink, 27 Nerd Disses is easily the geekiest compendium of haughty one-liners ever assembled.

Why would aliens come all this way just to invade Earth?

In movies, when aliens invade our planet, they usually have a ludicrous motivation. Like, they're after our water. Or our gold. (Hint: Asteroids have gold.) Space travel is incredibly difficult and expensive — so why would aliens actually bother to come and invade us? We asked some experts for reasons that actually… » 5/02/13 1:30pm 5/02/13 1:30pm

The most scientifically inaccurate Mars movies ever

This week on the io9 show, we ask why it is that NASA can put a robot on Mars, but Hollywood can't make any realistic movies about the red planet. We examine the worst Mars movies ever, and special guest Phil Plait (the good astronomer behind the Bad Astronomy blog) helps us figure out how realistic they are.… » 8/10/12 12:27pm 8/10/12 12:27pm

How Actual Science Can Make Science Fiction Stories Cooler

How do the minds behind Battlestar Galactica, Prometheus, X-Men: First Class, and Torchwood go about juggling science fact and science fiction, to tell a believable story? Bad Astronomy's Phil Plait hosted a panel at San Diego Comic-Con yesterday to discuss this issue, along with the making and breaking canon in… » 7/13/12 8:40am 7/13/12 8:40am

How I Stopped Worrying (About Science) and Learned to Love the Story

When I was a kid – and who am I kidding; when I was an adult too – I made fun of the science in movies. "That's so fakey!" I would cry out loud when a spaceship roared past, or a slimy alien stalked our heroes. » 5/26/12 1:30pm 5/26/12 1:30pm

The Most Beautiful Video of the Moon We've Seen in Ages

Unless you're an astronaut, we're willing to bet that you have never seen the Moon depicted as stunningly as it is here. For close to three years now, NASA's Lunar Reconnaissance Orbiter has been snapping high resolution photos of the Moon's surface. Now, the Goddard Visualization Studio has used those images to… » 3/02/12 3:23pm 3/02/12 3:23pm

You've never seen a solar eclipse quite like this

This morning, at 9:47 am ET, the Moon passed in front of NASA's Solar Dynamics Observatory, temporarily blocking the satellite's view of the Sun. Fortunately for all of us, the Observatory's cameras were rolling — and what it captured is an incredible sight to behold. » 2/21/12 3:37pm 2/21/12 3:37pm

Awesome new science show "Bad Universe" has our full attention

Last night was the debut of io9 pal Phil "bad astronomer" Plait's new Discovery show, Bad Universe. It was an explodey investigation of what would happen if Earth were hit with an asteroid, and how we could prevent it. » 8/30/10 4:00pm 8/30/10 4:00pm

This Galaxy Is Built For Speed

Check out this galaxy's weird curved shape, almost like an arrow-head. That's because it's hurtling through the Fornax cluster 600 km per second. Picture it screaming in fear and exhilaration as it roars towards a galactic collision. » 2/24/10 4:30pm 2/24/10 4:30pm
