Settling a long-standing scientific debate, Los Alamos scientists have demonstrated conclusively how electromagnetic waves accelerate ordinary electrons in the belts of radiation outside Earth's atmosphere to a state where they become "killer electrons," particles that are hazardous to satellites, spacecraft, and astronauts. picked by AutumnLotus 11 months ago

Two decades of scrutinizing Saturn are finally paying off, as scientists have discovered a wave pattern, or oscillation, in Saturn's atmosphere only visible from Earth every 15 years. picked by AutumnLotus 3 months ago

Scientists analysing data gathered by the Cassini spacecraft have confirmed the presence of heavy negative ions in the upper regions of Titan’s atmosphere. These particles may act as organic building blocks for even more complicated molecules and their discovery was completely unexpected because of the chemical composition of the atmosphere (which lacks oxygen and mainly consists of nitrogen... read full post picked by AutumnLotus 8 months ago

Geologists have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today. The study suggests that upheavals in the earth’s crust initiated a kind of reverse-greenhouse effect 500 million years ago that cooled the world’s oceans, spawned giant plankton blooms, and sent a burst of oxygen into the atmosphere. picked by AutumnLotus 9 months ago

Jupiter's volcanic moon Io is veiled by a thin atmosphere, but how much its volcanoes and chunks of frozen gas contribute to its atmosphere has puzzled scientists for decades. The New Horizons spacecraft recently documented the moon's glowing aurora, however, giving researchers a chance to solve the atmospheric mystery. picked by AutumnLotus 9 months ago

Magnetic waves ripple through the Sun's outer atmosphere with enough energy to heat the region to its astonishing temperature of millions of degrees, new views from the Hinode spacecraft suggest. If correct, the waves could solve a decades-long puzzle about the source of this heat. Includes video. picked by AutumnLotus 8 months ago

A $205 million upgrade will allow a laser-wielding observatory to monitor tens of thousands of galaxies for mysterious gravitational waves. Leading investigators are confident that the Advanced LIGO (Laser Interferometer Gravitational-wave Observatories) Project will be able for the first time to detect gravitational waves from neutron stars and black holes, as predicted by Einstein's theory of ge... read full post picked by AutumnLotus 4 months ago

Watching the stars set from the surface of the Earth may be a romantic pastime but when a spacecraft does it from orbit, it can reveal hidden details about a planet’s atmosphere. It works by watching stars from space, while they drop behind the atmosphere of a planet under investigation, before disappearing from view below the planet’s horizon. picked by AutumnLotus 9 months ago

Faint, fleeting blue flashes of radiation emitted by particles that travel faster than the speed of light through the atmosphere may help scientists solve one of the oldest mysteries in astrophysics - the origin of cosmic rays—subatomic particles of matter that stream in from outer space. picked by AutumnLotus 8 months ago

Taking a page from Nature herself, a team of researchers developed a method to enhance removal of carbon dioxide from the atmosphere and place it in the Earth's oceans for storage. picked by AutumnLotus 9 months ago

University of Arizona astronomers have pinpointed the origin of powerful bursts from nature's most magnetic objects. The bursts are from "magnetars," some of the most enigmatic objects in the universe. picked by AutumnLotus 10 months ago

The universe’s clock has neither a start nor finish, yet time is finite according to a New Zealand theorist. The theory, which tackles the age-old mystery of the origin of the universe, along with several other problems and paradoxes in cosmology, calls for a new take on our concept of time. picked by AutumnLotus 9 months ago

10 Watt radio stations that can only be heard from a few miles away are proliferating so fast the FCC can't keep up. Can "free radio" become a movement? picked by Fanatic 2 years ago
