The space-faring mice spent about 28 days in those conditions before returning to Earth in April. Mortreux and her colleagues then analyzed the weight, strength and movement of the 23 surviving animals and compared them with their preflight measurements and those of mice that stayed on 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 ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally. When you purchase through links on our site, we may earn ...

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.

This week in space: Obama wants a Mars shot, you can help NASA search for gravity waves via the magic of distributed computing, and a Jupiter-class planet with rings so huge, they'd nearly reach the Sun from Earth. Share on Facebook (opens in a new window ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

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.

The properties of  a microgravity environment enable more precise drug formulation, particularly for biologics and protein-based drugs.
