There’s been dozens of probes that have gone out exploring the solar system since 1959's Luna 2 probe. PopChartLab has gone and noted down each one since in this beautiful poster of the Solar System.
There could be a new ninth planet floating beyond the dark edges of our solar system, according to new research published in The Astronomical Journal from CalTech professors Mike Brown and Konstantin Batygin.
On the 23rd and 24th of January, 1930, a young astronomer working in Flagstaff, Arizona, scanned a small patch of the night sky. He was taking pictures of star positions, looking for anomalies that would signal movement somewhere at the edge of the solar system. He took the pictures then set them aside, not realizing…
Dwarf planets, comets, and asteroids are all the rage these days, but we shouldn’t neglect our Solar System’s outer gas planets and their moons. In this new NASA video, 70 days of Neptunian activity was compressed down to 34 seconds — and the effect is pretty damned cool.
On August 25, 1989, Voyager 2 sailed past Triton, capturing our first real look at Neptune's moon. With half the moon lost in shadow, we only got a glimpse of the icy moon. Now that footage has been restored and enhanced for your viewing pleasure.
Faster than you can say "trans-Neptunian object" three times, the reaches beyond Neptune's orbit start to fill out in this animation. And it's astounding. Dots representing icy bodies large and small fill the area.
Neptune has a moon called Naiad that was discovered by Voyager 2 in 1989 when the space probe made its flyby — but it hasn't been heard of since. Now, some 24 years later, astronomers have finally been able to spot it from Earth, and they did so using archived photographs.
Most of the space porn we come across is constructed from recorded images of objects in space. But painter Erik Olson prefers to interpret our solar system through his own lens, rendering our celestial neighbors with oil on canvas.
It's been a decade since astronomers last spied a moon orbiting Neptune. Now, the Hubble Space Telescope has spotted a new satellite circling our solar system's most far-flung planet.
Almost fifty years after his death, Frank R. Paul remains one of the biggest names in science fiction art and pulp magazine illustration. These visions of life on moons and planets throughout our solar system (recently posted to reddit with no attribution to Paul, his work, or his impact) provide us with another…
Pretty much everyone can rattle off the names of our solar system's eight (formerly nine) planets, but ask the average person to list some moons and you'll be lucky if they can tell you more than two or three.
Back in the Forties, the science fiction rag Planet Comics published the ongoing feature "Life On Other Worlds." This section peppered scientific know-how amongst whatever gonzo shit the writer happened to make up. Here's a tour of our Solar System using old issues of Planet Comics. Did you know that Mars is occupied…
This solar system just doesn't work. According to a new computer simulation, the planets could never have come together in their current configuration. The only explanation is that we once had a fifth gas giant...and it's still out there somewhere.
Exoplanet Kepler-19b orbits its star in ways that violate the laws of physics, speeding up and slowing down its orbit for no apparent reason. The only explanation is a second, hidden planet...making it the first "phantom" exoplanet ever found.
We've just learned that there's strong evidence that saltwater flows on the surface of Mars. It's another reminder that water is everywhere in our solar system, whether it's ice, vapor, or liquid. Here's a handy guide to where all the water can be found.
Trojan asteroids are objects that share a planet's orbit around the Sun but reside in what are basically gravitational dead zones. We've discovered Earth's first Trojan asteroid...but how did it get there, and why have we only just found it?
Last week saw Neptune Day, the first anniversary - in Neptune years - of the planet's discovery on September 23, 1846. That got us thinking: what are the "birthdays" for all the other planets? Here's a handy, mildly insane guide.
July 11, 2011 marks the first full orbit of the planet Neptune since its discovery on the night of September 23-24, 1846. The discovery of Neptune is a fascinating story, full of near misses and the triumph of math.
When it come to making your head spin, Jupiter revolves on its axis in less than 10 hours. Up until now, it was the only gas planet in our solar system that had an accurate spin measurement.
