A Stunning Glimpse Of The Moon's Phases As Seen From The Other Side

Our moon is tidally locked to the Earth, which means we never get to see its opposite side. But there's a prevailing notion that the far side is perpetually shrouded in darkness. This is absolutely not true, as this visualization from NASA beautifully illustrates. » 2/06/15 6:30am 2/06/15 6:30am

This Crater Is Our Best Shot At Finding Water On The Moon

If we're going to travel out in the universe, we're going to need a plentiful supply of water, perhaps much more than we can simply carry. Which is why this crater on the moon is so exciting. » 2/05/15 12:00pm 2/05/15 12:00pm

A Tiny Moon Putters Away From Asteroid During Near-Earth Encounter

Asteroid 2004 BL86 charmed us with its tiny, dive-bombing moon during its close approach at the start of this week. Now JPL has released more radar data of the minuscule moon's trajectory guaranteed to charm us with its unwavering obedience to the laws governing orbital dynamics. » 2/02/15 12:05am 2/02/15 12:05am

How It Would Look If Other Types Of Stars Were Close As The Sun

What would it look like if other stars were as close as the sun? For starters, we may have more than one, and it may be either much bigger or smaller than our current orbital star, as shown in these videos, which explore a hypothetical universe where our sun has been replaced with other stars and our moon with planets. » 1/29/15 9:20am 1/29/15 9:20am

Tiny Moon Dive-Bombs Asteroid During Near-Earth Flyby

Early this morning, a big (but not too big) asteroid made a close (but not too close!) pass by our planet. While totally unthreatening as a doomsday scenario, this particular asteroid makes for beautiful viewing: it has a tiny, orbiting moon. Update: More radar footage! » 1/26/15 7:10pm 1/26/15 7:10pm

This Is The Strangest Way We've Ever Seen The Moon Move

Everything seems normal, as the Moon drifts below the horizon. Then it suddenly flattens out into a disc and turns bright red. What's going on? It's not editing or animation. What you're seeing is an actual view of the Moon. » 1/26/15 12:20pm 1/26/15 12:20pm

Fancy Up Your Home With a Glowing Moon Credenza

My quest to find every possible item that could turn my home into a space oasis — provided I had a giant pile of money to that with — has now brought me to a glow-in-the-dark moon credenza. This is important to me. » 1/25/15 11:00pm 1/25/15 11:00pm

What Does Moonset Look Like From The International Space Station? 

Watch As The Space Station Passes Across The Face Of The Moon

As the third brightest object in our sky, spotting the ISS as it flies above our heads is a goal that can be firmly within our grasp. But what does it look like when the ISS, on a very rare occasion, crosses paths with our own Moon? » 12/31/14 10:30am 12/31/14 10:30am

The Real Story Of Apollo 17... And Why We Never Went Back To The Moon

On December 11, 1972, Apollo 17 touched down on the Moon. This was not only our final Moon landing, but the last time we left Low Earth Orbit. With the successful launch of the Orion capsule, NASA is finally poised to go further again. So it's important to remember how we got to the Moon — and why we stopped going. » 12/12/14 1:44pm 12/12/14 1:44pm

Send A Personal Memento To The Lunar Surface Via "MoonMail"

Astrobotic, a company that is competing to win the $30 million Google Lunar X-Prize by placing the first commercial lander on the Moon, is now offering the public the opportunity to mail their keepsakes on one-way trips to the lunar surface. » 12/12/14 8:40am 12/12/14 8:40am

A Mesmerizing Video Shows One Year Of The Moon’s Phases In Five Minutes

The Moon always keeps the same face to us, but not exactly the same face. Because of the tilt and shape of its orbit, we see it from slightly different angles over the course of a month. And when each month is compressed into 24 seconds, as in this video, our changing view of the Moon makes it look as if it's wobbling. » 12/11/14 10:40am 12/11/14 10:40am

Here's How We'll Build A Cheap, Safe Lunar Base

The "magnificent desolation" of the Moon might offer some great views, but otherwise it's a lousy place to live. Human explorers would need protection from a constant bombardment of radiation and extreme temperature shifts. A new video shows how we can inexpensively build an ideal shelter with robotic 3D printers. » 11/07/14 11:30am 11/07/14 11:30am

12 Greatest Psychological Dramas That Just Happen to be Set in Space

Humanity is never thrown into so stark relief as when we journey into space. In that alien environment, we find out who we are.

The Moon Is A Laboratory

Our moon missions have served a variety of purposes ranging from technical ones to the satisfaction of our curiosity. But the moon has also served one very practical and immediate purpose: It's a laboratory. Here's a history of how we've used the moon as a scientific facility — and how we might do it in the future. » 11/03/14 4:20pm 11/03/14 4:20pm
