Let’s be very clear here: There is simply no possibility that Asteroid 2013 TX68 will get close enough to hit Earth when it flies by on March 5th. What it may do, though, is come close enough to be visible.
Something strange has been happening on the surface of Pluto. There’s a series of hills, each about a couple miles across, and they appear to be moving.
In 1983, Sally Ride became the first American woman to travel into space. Today, PBS Digital Studio released a short animated film featuring an interview between Ride and Gloria Steinem from that very same year. It’s a great retrospective on Ride’s early career—but it’s also a reminder that obnoxious gender biases…
Look at this picture of Saturn. Can you see the biggest ring? Are you sure?
When NASA’s first mission to Mars kicks off in 2018, the goal is to make sure that the agency’s new rocket can make it out there before they start sending people. So, instead of a crew, this first mission will be filled with equipment for 13 science projects...including a gigantic laser flashlight that will orbit the…
Last week the world mourned for the 1986 explosion of the Challenger space shuttle that claimed seven lives. Today, we mark the 13th anniversary of Space Shuttle Orbiter Columbia’s breakup upon reentry into Earth’s atmosphere.
We tried NASA’s brand new 360 degree Mars panoramic viewer for your phone, and we think it’s about as good a Mars view as you’re going to get right now, lacking a spaceship. Test it out for yourself below.
Okay, we’re just going to say it: From its mysterious glowing patches to its two-faced mountain, dwarf-planet Ceres is plain weird. And with the latest fly-over look at its surface from NASA, things are getting even stranger.
The cosmos is littered with clouds of star-forming gas, but few are as well studied as the Smith Cloud, set to crash into our galaxy in 30 million years. God-fearing humans might ask: Where did this unholy dust ball come from, and why is it heading straight for us? Now, science has the answer.
Curiosity is busy poking and prodding the Bagnold Dunes, learning some new tricks in the first-ever interplanetary fieldwork on a sand dune. And of course it looks absolutely stunning while doing it in this latest sand dune selfie.
Thirty years ago, the space shuttle Challenger exploded. The tragedy shocked a nation caught in launch fever, and reshaped how NASA thought about risk.
This is what one day looks like on Earth from space. The footage condenses 24 hours of imagery from Japan’s Himawari-8 satellite into 12 seconds and shows us how the our beautiful blue marble peels itself from the darkness in unbelievable detail. The reveal of Earth is just beyond words. No planet is as beautiful as…
Today was supposed to mark a step forward in human flights for the Apollo program. Instead, flames exploded inside the capsule during a pre-flight test. The fatal accident changed the nature of America’s space program.
Our planet can be too beautiful to be plausible some days. This frozen lake in the Himalayas is shockingly deep blue set against the slightly-oxidized rusty landscape. And it’s completely real, photographed from the International Space Station.
There are lots of things most of us never contemplate when we fantasize about living in space: What happens to your arms when they don’t naturally fall at your sides? Do you keep your callouses when you aren’t walking? What’s it like to sleep in free fall?
Sending something up into space? Having it stay up there while people live there as it orbits the Earth? Becoming an outpost far, far away from home? Just incredible. Building a habitable space station satellite will always be an amazing feat of engineering and planning and sheer human ingenuity. Here are all the…
Behold Trumpler 14, a dazzling star cluster located 8,000 light-years from Earth. Situated within the Carina Nebula, it’s home to one of the highest concentrations of massive, bright stars in the Milky Way. But as spectacular as these stellar objects appear be, their majestic appearance comes at a price.
Are you awake before dawn? Good. Go outside. Look east. Bask in the astronomical wonder of seeing all the brightest planets out at the same time, pinpricks of worlds drifting up from the horizon. Missed it? Try again any morning for the next month.
On Friday, Blue Origin launched their same New Shepard rocket booster that it launched into space two months ago. Looks like the commercial space race for reusable rockets is on—SpaceX is flashier with bigger trajectories, but Blue Origin keeps winning the race to first.
Navigating in deep space is tricky, particularly when you need to keep up interplanetary synchronized clocks. NASA is convinced we can do better with a new atomic clock they’re testing in orbit this year. Here’s how it works, as illustrated by an adorably consternated second hand.
