Let’s learn about Mars

Traveling to Mars offers many challenges, including life without gravity, cosmic rays and communication delays.

Space

Scientists Say: Gravity

Gravity is a fundamental force that attracts objects with mass to other objects with mass. It decreases with distance.

Tech

Let’s learn about space robots

Space robots can take pictures of other planets, analyze samples of their surface and even peer into their interiors.

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.

Space

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.

Tech

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.

Planets

Planets with hydrogen skies could harbor life

Microbes can live in a hydrogen atmosphere. This points to new space worlds that host alien life.

Planets

Let’s learn about Jupiter

This gas giant is home to a massive storm that has lasted hundreds of years. It’s also surrounded by dozens of moons.

Earth

Weight lifting is this planetary scientist’s pastime

Beck Strauss uses magnetic fields to explore the makeup of Earth and other planets.

Space

Scientists Say: Gas giant

These gargantuan planets, such as Jupiter and Saturn, are mostly made up of hydrogen and helium gas.

Glass beads help scientists puzzle out how baby planets grow

Researchers have mimicked the first stages of planet formation in the lab. All they needed were glass beads and a catapult.
