If bacteria stick together, they can survive for years in space
Tiny clumps of bacteria can survive at least three years in outer space. This raises the prospect of interplanetary travel by microbial life.

A weird cousin of our solar system is caught on camera
New photo reveals a cousin to our solar system. It’s star has a mass similar to the sun’s and is orbited by two gas giant planets.

Explainer: Stars and their families
Most pinpoints that light the night sky are raging infernos we call stars. As adults, many will create new elements that they later cast off into the cosmos.

Milky Way’s tidal forces are shredding a nearby star cluster
The nearest star cluster is being pulled apart, due largely to the tidal forces of our galaxy, the Milky Way. Bye bye, Hyades!

Scientists Say: Solar
What do solar energy, the solar year and solar flares have in common? They’re all related to the sun.

Saturn’s moon Titan may host lots of dried lakes
Suspicious spots around the moon’s middle could be the beds of ancient lakes. If so, this might solve a 20-year-old mystery.

Let’s learn about exoplanets
Exoplanets are planets outside of our solar system. Scientists are finding out more about them than ever before.

Spotted: Milky Way’s giant gas bubbles in visible light
The bubbles have different colors, based on how the gas inside them moves. That could give clues to how the bubbles developed.

Developing planet emerges in a swirl of gas
Images of a young star 520 light-years away show a spiral of gas and dust swirling around it. A twist inside the spiral appears to be a planet forming.
