A low-cost telescope that takes its inspiration from Galileo — the famed Italian astronomer who discovered the moons of Jupiter in the 16th century — is once again available to celebrate the United Nations 2015 International Year of Light.
11 June 2015, 12:12 PM ET
New images of Jupiter's volcanic moon Io show "hotspots" happening in different spots on a volcanic lake. Even more surprising given the lake's small size: the images were taken from Earth.
09 June 2015, 06:20 AM ET
NASA officials hope the agency's flyby mission to Europa in the 2020s paves the way for future missions to the Jupiter moon — including, perhaps, one that touches down to search for signs of life.
05 June 2015, 11:20 AM ET
Engineers are looking to automate some of the simple decision-making steps undertaken by Mars rovers and orbiters, which could dramatically improve the science they are able to perform in the search for habitable environments.
31 May 2015, 07:00 AM ET
NASA announced the science instruments for its mission to Europa, SpaceX was certified for U.S. military launches and a tiny solar-sailing spacecraft suffered a glitch in orbit. Here's a look at Space.com's top stories of the week.

Hercules, Boötes (Herdsman), and Draco (Dragon) constellations are highlights for sky gazers in June. Also, Venus and Jupiter are bright in the evening sky and Jupiter rings are viewable with binoculars in the southern sky.
26 May 2015, 05:02 PM ET
The Europa probe will carry supersharp cameras, a heat detector, ice-penetrating radar and a variety of other gear that will help researchers gauge the Jupiter moon's ability to support life as we know it.
20 May 2015, 10:33 AM ET
Jupiter's rapidly moving moons constantly surprise us with their dance around the giant planet. There will be two spectacular shadow plays this week.
20 May 2015, 06:30 AM ET
A giant alien planet is seemingly too big for its cool dwarf star, raising questions about how it could possibly have formed. Further investigation of this odd exoplanet could help scientists understand how planets form, researchers said.
13 May 2015, 07:19 AM ET
The reddish-brown lines that crisscross the icy surface of Europa may be radiation-blasted sea salt from the Jupiter moon's underground ocean. Radiation-blasted salt turned dark during a lab experiment that mimicked Europa conditions.
11 May 2015, 07:01 AM ET
Small and economical "cubesats" already eye our planet from orbit. But such bantam craft are about to start pushing out into deep space, helping researchers study and explore the moon, asteroids and other distant bodies.
11 May 2015, 07:00 AM ET
The new ideas funded by the NASA Innovative Advanced Concepts (NIAC) program include a squid-like amphibious rover that could explore icy, ocean-harboring moons such as the Jupiter satellite Europa.

Have you ever wondered what it would be like to live on the moon? What about Mars, or Venus or Mercury? We sure have and that's why we decided to find out what it might be like to live on other worlds in our solar system, from Mercury to Pluto and beyond
