New research finds that moons can be flung into space paired with a planetary partner, making it possible for these wandering moons to host life.

The Universe May Be Full of Habitable Worlds That Have No Sun

What happens when a moon goes rogue?

Signs of life could be hidden beneath 'Oumuamua's outer layer.

Our first interstellar visitor is covered in a layer of "organic sunscreen"

Researchers say our first interstellar visitor has a natural layer of protection against the Sun's cosmic rays, and it could be covering an icy core.

These small, low-cost CubeSats could zip through the solar system on exploratory missions.

A team at Purdue University have designed a water vapor propulsion system that could make CubeSats more effective for exploration than larger satellites.

Small, Water-Powered Satellites Could Be the Future of Space Exploration

Powered by water vapor, these little satellites could go far.

Each of these satellites is smaller than a credit card.

The test was designed to reveal how well the satellites' electronics systems and radio communications performed in orbit.

These Satellites Are the Smallest to Ever Reach Earth’s Orbit

They put us one step closer to faster, cheaper interstellar travel.

Science fiction writer Kim Stanley Robinson explores the dangers posed by long-term space travel and colonization in his novel Aurora.

Should We Try to Colonize Other Worlds or Stay and Fix Earth?

Alien worlds await. Should humans really go?

Living on a planet orbiting a black hole might be a reality in our future.
