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.
- Climate
Scientists Say: Solar
What do solar energy, the solar year and solar flares have in common? They’re all related to the sun.
- Planets
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.
- Planets
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.
- Space
Scientists Say: GPS
A GPS system relies on satellites orbiting the planet, constantly sending signals back to receivers on Earth.

Oldest disk galaxy puts a new spin on galaxy growth
A spinning disk galaxy has been found in the early universe. Its existence is a surprise.

Wiggly wheels might help rovers plow through loose lunar soils
New design lets wheels ascend hills too steep for regular robots and paddle through loose soils without getting stuck.

Let’s learn about the sun
The sun is our own personal star and the reason life exists on Earth.
- Materials Science
Astronauts may be able to make cement with their own pee
Lunar dust and a compound found in urine might one day be used to build future dwellings on the moon, a new study finds.
- Physics
Scientists Say: Spaghettification
Black holes cram a lot of mass into a small area. When another object gets close, the black hole’s gravity can stretch it into a noodle-like strand.
