Thanks to not-so-recent advances in technology, we can shoot just about anything into space, or at the very least into Earth's orbit. At first, we launched spy satellites during the Cold War, but once ...

All the fundamental forces are thought to be carried by a particle, but a new mathematical model suggests gravity may be a striking exception. Building on a decades-old idea, researchers have revealed ...

In microgravity, flames form a spherical shape due to the absence of buoyancy-driven convection. Meanwhile, flames are teardrop-shaped due to the upward flow of hot air on Earth.

NASA astronauts Suni Williams and Butch Wilmore are back on Earth after 286 days in space. Former astronaut and ISS commander Terry Virts and former NASA Administrator Major General Charles Bolden ...

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.

They are entirely feasible and, with sufficient funding, we could build one within months or years! Due to the effect of the Coriolis force on the semicircular canals (three tubes in the inner ear), ...

Space travel alters hemoglobin gene expression, increasing fetal globin production and shifting erythropoiesis to a primitive type. Low gravity in space increases the risk of coagulation disorders, ...
