The thicknesses of ice shells covering our solar system's ocean-bearing moons could provide hints about whether these mysterious bodies may harbor life.
Our Solar System’s moons and planets have water—in the form of ice, vapor, and even oceans. Scientists are finding more evidence of water outside of Earth.
Just the third-ever confirmed interstellar object has been detected in our solar system. Here's what we know. (Spoiler: It's ...
WSJ’s Danny Lewis speaks to University of Arizona astronomer Chris Impey about what makes a planet habitable and how learning about exoplanets can teach us more about our own world.
The newly discovered moons give Jupiter a total of 92 moons, now more than Saturn and the most of any planet in our solar system.
When the Sun runs out of hydrogen fuel and expands into a red giant, it will eventually encompass the innermost planets of the solar system, out to about Earth's orbit. Being closer to our ...
Mars might become more temperate and hospitable to life. In addition, it could well be a boon for the gas giant Jupiter and its moons. That's because the habitable zone of the solar system will ...
The closest analogues that we have in our own solar system to such water-rich worlds are the moons of Jupiter and Saturn.
While we have a precise (and probably accurate) age for the solar system, we do not have precise ages for each planet.
The solar system has many more moons than the one we can see in the sky. But how many do we actually know about? And how many more are waiting to be discovered?
The Sun's expansion into a red giant will engulf the inner planets, drastically increasing temperatures in the outer solar system. The habitable zone will expand to 10-50 AU, potentially making ...
In particular, white dwarf planetary systems offer an interesting population of potentially habitable planets (and moons) that can be studied by our current (and upcoming) space-based observatories.
