This Far-Off Solar System Bears a Startling Resemblance to Our Own

An international team of astronomers has detected a planet very similar to Jupiter orbiting at the same distance from a Sun-like star. And because the age and chemical composition of this system is similar to our own, it likely features an inner collection of rocky planets. Call it solar system 2.0. » 7/16/15 9:00am 7/16/15 9:00am

Astronomical Knolling Is The Prettiest Way To Organize Objects In Space

What happens when a planetary scientist has a love for order? He creates code that sorts everything from our solar system’s moons to exoplanets into graceful spirals where every object is slightly smaller than the one before. Astronomical knolling is my new favourite way to contemplate the vast scale of space. » 4/18/15 5:30pm 4/18/15 5:30pm

This Elevation Map Of Mars Makes The Red Planet Much More Colorful

In this brand new map of the Ares Vallis region of Mars, released by the German space agency DLR, you can see the true differences in height between the high and low parts of our neighboring planet. The highest parts, expressed in red, are about 4000 meters (2.4 miles) above the lowest parts, in blue. » 4/14/15 6:30pm 4/14/15 6:30pm

NASA Chief Scientist Predicts We'll Find Signs Of Alien Life By 2025

Here's the full quote, as delivered by NASA Chief scientist Ellen Stofan at Tuesday's panel discussion on the Agency's search for habitable worlds and alien life: "I think we're going to have strong indications of life beyond Earth within a decade, and I think we're going to have definitive evidence within 20 to 30… » 4/07/15 3:25pm 4/07/15 3:25pm

The Quest To Find Another Saturn Just Got One Step Closer

If our solar system is any indication, planets with rings around them are quite common, but finding extrasolar ringed planets has proven difficult. Now astronomers have developed a surprisingly simple method for detecting these distant "exorings." It'll only be a matter of time before we find the next Saturn. » 3/11/15 7:30am 3/11/15 7:30am
