What feels like up may actually be some other direction depending on how our brains process our orientation, according to psychology researchers at York University's Faculty of Health.


By capsule, helicopter, boat, plane, and car, space station science experiments are about to make a first of a kind journey back to researchers on Earth.


SpaceCast Weekly is a NASA Television broadcast from the Johnson Space Center in Houston featuring stories about NASA's work in human spaceflight.


As the world leaves behind the strange and challenging year of 2020, we look towards 2021 with a mixture of relief and expectation.

NASA has chosen four small-scale astrophysics missions for further concept development in a new program called Pioneers.


It is during rare merging events that galaxies undergo dramatic changes in their appearance and in their stellar content. These systems are excellent laboratories to trace the formation of star clusters under extreme physical conditions.


At 10:10 a.m. EST, flight controllers on the ground sent commands to release the Northrop Grumman Cygnus spacecraft from the Canadarm2 robotic arm after earlier detaching Cygnus from the Earth-facing port of the Unity module.
