How strong is gravity on other planets?

Gravity is a fundamental force of physics, one which we Earthlings tend to take for granted. You can't really blame us. Having evolved over the course of billions of years in Earth's environment, we are used to living with ...

JPL-developed clean energy technology moves forward

A team of scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., in partnership with the University of Southern California in Los Angeles, developed a Direct Methanol Fuel Cell technology for future Department ...

Flow-through electrodes make hydrogen 50 times faster

Electrolysis, passing a current through water to break it into gaseous hydrogen and oxygen, could be a handy way to store excess energy from wind or solar power. The hydrogen can be stored and used as fuel later, when the ...

New thruster design increases efficiency for future spaceflight

Hall thrusters (HTs) are used in earth-orbiting satellites, and also show promise to propel robotic spacecraft long distances, such as from Earth to Mars. The propellant in a HT, usually xenon, is accelerated by an electric ...

The birth of a very-high-field superconductor

The strong magnetic fields of an MRI scanner or a particle accelerator are generated efficiently by electromagnets that have superconducting wire in their coils. A group of scientists has discovered how to make better wires ...

Voyager 1 magnetic data surprise intrigues researchers

(Phys.org) —A University of Alabama in Huntsville graduate student and a recent UAH doctoral graduate are exploring surprising data from Voyager 1's crossing of the heliopause into the interstellar medium of our galaxy.

What is the biggest planet in the solar system?

Ever since the invention of the telescope four hundred years ago, astronomers have been fascinated by the gas giant of Jupiter. Between it's constant, swirling clouds, its many, many moons, and its Giant Red Spot, there are ...
