Cells function differently under low gravity conditions. Rather than send lab samples to space, researchers are developing Earth-bound tools to more easily study microgravity’s effects on biology.

Hubble’s work pushed the field of astronomy forward, starting with his paper demonstrating that some objects exist outside our galaxy.

Wearing the wrong shoe on Earth can lead to injury. Researchers still need to figure out the physical consequences of spending a long time walking around on the Moon.

Solar cells made with organic materials could be better than conventional silicon and gallium arsenide for generating power in space.

SpaceX has brought both well-paying jobs and rocket debris to southern Texas.

Even without recovering New Glenn’s reusable booster, Blue Origin has joined the ranks of commercial companies with rockets able to launch into orbit.

The Los Angeles fires may be the most costly natural disaster in US history. An expert on safety, risk reduction and complex systems calls for a blue-ribbon commission to analyze their causes.

Their source could be the core of a dead star that’s teetering at the black hole’s edge, MIT astronomers report.

A rocket needs to overcome the force of gravity to leave Earth behind.

Nations will need to tread carefully on the Moon in order to avoid conflict.
