NASA once sent over 2,000 jellyfish into space to study how gravity affects biological development. The unusual experiment revealed surprising insights about balance, microgravity and life beyond Earth.

From Aliens to Avatar, James Cameron is widely known for his legendary space blockbusters. Few filmmakers have contributed to the subgenre as much as Cameron, who also serves as a member of the Mars Society and the NASA Advisory Council. And yet, Cameron ...

It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in near-zero gravity (microgravity) environments. However, the gravity threshold needed to maintain sufficient muscle health in space is still unclear.

Spacecrafts don’t just rely on rockets—they use planets to pick up speed! Spacecrafts don’t just rely on rockets—they use planets to pick up speed! It’s called a gravity assist, and it’s one of the cleverest tricks in space exploration.

Add Yahoo as a preferred source to see more of our stories on Google. From aboard the International Space Station, astronaut Don Pettit shared footage of himself playing with a yo-yo in zero gravity, demonstrating how the toy behaves differently in space.

As we explore more of the universe, the physical impacts of living in microgravity continue to be one of the primary obstacles to long-term space trav.

A dip in Earth's gravity field beneath Antarctica is helping scientists track deep-Earth changes over tens of millions of years. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Breaking space news ...
