What happens when ultracold atomic spins are trapped in an optical lattice structure
Every electrical device, from a simple lightbulb to the latest microchips, is enabled by the movement of electrical charge, or current. The nascent field of 'spintronics' taps into a different electronic ...
A habitable environment on Martian volcano?
(Phys.org) —Heat from a volcano erupting beneath an immense glacier would have created large lakes of liquid water on Mars in the relatively recent past. And where there's water, there is also the possibility ...
How mighty Jupiter could have changed Earth's habitability
Is Jupiter a friendly planet, Earth's enemy, or perhaps both? For decades, scientists have talked about how the giant gas planet keeps some asteroids from striking our small world, while others have pointed ...
Mapping the behavior of charges in correlated spin-orbit coupled materials
A team of Boston College physicists has mapped the inner atomic workings of a compound within the mysterious class of materials known as spin-orbit Mott insulators. The findings confirm the properties that ...
Kepler finds a very wobbly planet
(Phys.org) —Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. That is the situation on a weird, wobbly world found by NASA's planet-hunting ...
NASA Mars spacecraft reveals a more dynamic red planet
(Phys.org) —NASA's Mars Reconnaissance Orbiter has revealed to scientists slender dark markings—possibly due to salty water - that advance seasonally down slopes surprisingly close to the Martian equator.
Figures of eight and peanut shells: How stars move at the center of the galaxy
(Phys.org) —Two months ago astronomers created a new 3D map of stars at the center of our galaxy (the Milky Way), showing more clearly than ever the bulge at its core. Previous explanations suggested that ...
Suspected dust ring in Venus's orbit confirmed
Astronomers see misaligned planets in distant system
Using data from NASA's Kepler space telescope, an international team of astronomers has discovered a distant planetary system featuring multiple planets orbiting at a severe tilt to their host star.
Mars crater may actually be ancient supervolcano, study says
(Phys.org) —A research project led by Joseph R. Michalski, Senior Scientist at the Planetary Science Institute, has identified what could be a supervolcano on Mars – the first discovery of its kind.
Lichens can survive space conditions for extended periods
A new study shows that a large percentage of hardy lichens exposed to space conditions for one and a half years remain viable after returning to Earth. The lichen Xanthoria elegans was part of the lichen ...
Once in million years: Comet buzzing Mars on Sun
(AP)—The heavens are hosting an event this weekend that occurs once in a million years or so.
NASA mission finds widespread evidence of young lunar volcanism
NASA's Lunar Reconnaissance Orbiter (LRO) has provided researchers strong evidence the moon's volcanic activity slowed gradually instead of stopping abruptly a billion years ago.
NASA prepares its science fleet for Oct. 19 Mars comet encounter
NASA's extensive fleet of science assets, particularly those orbiting and roving Mars, have front row seats to image and study a once-in-a-lifetime comet flyby on Sunday, Oct. 19.
