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.

And because the habitable zone shifts even during the red giant phase as the Sun continues to evolve, no planet in our solar system will spend more than half a billion years in the new habitable ...

Just the third-ever confirmed interstellar object has been detected in our solar system. Here's what we know. (Spoiler: It's ...

Plus there are several moons that scientists think could be habitable scattered throughout the solar system, and that's a lot of variety just for our own neighborhood, so to speak.

Jupiter is already the biggest planet in our solar system. It used to be known as the planet with the second-most moons with 80, trailing only Saturn with 83.

However, our home planet is not likely to remain a comfortable, habitable world. Planets and moons farther away (Mars and beyond) won't be affected the same way, and the scenario is different for ...

Just to put things into perspective, consider the fact the largest such geysers we know of here in our solar system, the ones on Europa, release only 4,400 pounds (2,000 kg) per second.

Moving on, we come to Earth. Our home planet has just one major moon. However, ... "I think that there are probably about 10,000 moons in the solar system," Ashton said.

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 ...

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 ...
