NASA chief says the world may not be ready for Martian life

October 1st, 2019

NASA’s Mars 2020 mission will attempt to answer a number of questions about the Red Planet, and one of the most pressing is the search for life.

Jupiter had some major growth problems in its early years

August 28th, 2018

Jupiter is the largest planet in our Solar System, and the competition really isn’t even close. It’s an absolutely massive planet and it helped define what a gas giant planet truly is. Because of its size, it might be hard to imagine a time when Jupiter had a problem growing, but new research suggests that …

Astronomers discover bizarre rogue planet glowing with auroras

August 6th, 2018

When astronomers are searching the depths of space for new objects it’s typically easier to find undiscovered planets if they’re orbiting a star. That’s because spotting the dips in the star’s brightness as the planet passes in front of it gives away its presence. Finding a solitary planet — called a “rogue” planet — is …
