Warped shape of the galaxy

Dorota M. Skowron et al. made the first 3-D map of the galaxy. Sean Greene and Andrea Roberson reporting for the Los Angeles Times: Astronomers have understood since the 1950s that the galaxy is curved, but until now, they’ve based that idea on models and indirect measurements. Over a six-year period, the researchers took more than 100 images of the galaxy from their observatory in the Chilean Andes. In particular,...

Imaging Earth on the daily

Over the past four years, Planet deployed 293 satellites in low orbit to take a snapshot of Earth every day. This animation by Nadieh Bremer shows how the snapshot gets pieced together. Most of me is like, yeah awesome. But then there’s that remaining bit of me that is a little bit nervous. Tags: Nadieh Bremer, Planet, satellite imagery, space

Light from the center of the galaxy

This animated interactive explains how a research group is using light to measure the speed of objects millions of miles away. Light that is farther away will appear to be a different color than a light that is closer. So by measuring the rate of color shifts, they can estimate velocity. Tags: Albert Einstein, light, space

Atlas of all the moons in our solar system

National Geographic went all out on their atlas of moons. Space. Orbits. Rotating and interactive objects in the sky. Ooo. You’ll want to bookmark this one for later, so you can spend time with it. Tags: moon, National Geographic, space

The Moon in 4k resolution

Based on data gathered by the Lunar Reconnaissance Orbiter, NASA pieced together this high-resolution tour of the moon. At the two-minute mark they zoom in on a boulder in the middle of a 100-million-year-old crater, and it blew my mind. Tags: high resolution, moon, NASA, space

Apollo 11 conversations on the way to the moon

As you can imagine, there was plenty of conversation between Earth and Apollo 11 en route to the moon. Nicholas Rougeux visualized the back and forth with an interactive timeline. During the historic mission to the moon and back, some of the most famous words ever said were transmitted between the Apollo 11 spacecraft and Earth. Between those icons moments was a great deal of chatter—mostly about technical matters but...

A daily high-resolution image of Earth

Planet monitors Earth with hundreds of satellites, and after six years, they’ve built out their pipeline to piece together a full image on the daily. At Planet, we’ve been pursuing Mission 1: to image the entire Earth’s landmass every day. I couldn’t be more excited to announce that we have achieved our founding mission. Six years ago, our team started in a garage in Cupertino. Mission 1 was the north...

Tour of Saturn through Cassini, the satellite that crashes on Friday

About two decades ago, the Cassini satellite headed towards Saturn and has been orbiting the planet for 13 years. The satellite is scheduled to crash into Saturn’s atmosphere on Friday so Nadia Drake and Brian T. Jacobs for National Geographic toured through the satellite’s best finds. This is quite the scroller and feels pretty grand. No matter how many times it happens, it still blows my mind that satellites are...

Solar System in a bottle

From Little Planet Factory, a Solar System in a bottle made to scale: A small bottle attempting to maintain the correct scale between the 8 planets of the solar system at a scale of 1:5,000,000,000. Much as in reality the entire bottle is almost entirely dominated by the volume (and mass) of the four gas giants while the four solid planets settle almost dust like in comparison at the bottom...
