Moon mission delays could increase risks from solar storms      (via sciencedaily.com) 

Although patterns in the timing of moderate space weather events are known, the most extreme and dangerous events were thought to be random in their timing. This study found for the first time that extreme space weather occurs most frequently at predictable times during solar cycles, meaning space missions could be timed to avoid them.

In the emptiness of space, Voyager I detects plasma 'hum'      (via sciencedaily.com) 

NASA's Voyager I spacecraft has long since zipped past the edge of the solar system through the heliopause - the solar system's border with interstellar space - into the interstellar medium. Now, its instruments have detected the constant drone of interstellar gas (plasma waves).

Smartphone breath alcohol testing devices vary widely in accuracy      (via sciencedaily.com) 

The latest generation of personal alcohol breath testing devices pair with smartphones. While some of these devices were found to be relatively accurate, others may mislead users into thinking that they are fit to drive, according to a new study.

Quantum drum duet measured      (via sciencedaily.com) 

Like conductors of a spooky symphony, researchers have 'entangled' two small mechanical drums and precisely measured their linked quantum properties. Entangled pairs like this might someday perform computations and transmit data in large-scale quantum networks.

Physicists describe new type of aurora      (via sciencedaily.com) 

The famed northern and southern lights have been studied for millennia, but they still hold secrets. Physicists describe a new phenomenon they call 'diffuse auroral erasers,' in which patches of the background glow are blotted out, then suddenly intensify and reappear.

Scientists model Saturn's interior, explain planet's unique magnetic field      (via sciencedaily.com) 

New simulations offer an intriguing look into Saturn's interior, suggesting that a thick layer of helium rain influences the planet's magnetic field.

Hubble watches how a giant planet grows      (via sciencedaily.com) 

NASA's Hubble Space Telescope is giving astronomers a rare look at a Jupiter-sized, still-forming planet that is feeding off material surrounding a young star.

Measuring the Moon's nano dust is no small matter      (via sciencedaily.com) 

Researchers are now measuring tinier moon dust particles than ever before, a step toward more precisely explaining the Moon's apparent color and brightness. This in turn might help improve tracking of weather patterns and other phenomena by satellite cameras that use the Moon as a calibration source.

Simple robots, smart algorithms      (via sciencedaily.com) 

Inspired by a theoretical model of particles moving around on a chessboard, new robot swarm research shows that, as magnetic interactions increase, dispersed 'dumb robots' can abruptly gather in large, compact clusters to accomplish complex tasks. Researchers report that these 'BOBbots' (behaving, organizing, buzzing bots) are also capable of collectively clearing debris that is too heavy for one alone to move, thanks to a robust algorithm.

Enormous flare from sun's nearest neighbor breaks records      (via sciencedaily.com) 

On May 1, 2019, researchers observed a record-setting flare from the star Proxima Centauri -- a burst of energy roughly 100 times more powerful than any similar event seen from Earth's sun.

New approach to centuries-old 'three-body problem'      (via sciencedaily.com) 

The "three-body problem," the term coined for predicting the motion of three gravitating bodies in space, is essential for understanding a variety of astrophysical processes as well as a large class of mechanical problems, and has occupied some of the world's best physicists, astronomers and mathematicians for over three centuries. Their attempts have led to the discovery of several important fields of science; yet its solution remained a mystery.

New research reveals secret to Jupiter's curious aurora activity      (via sciencedaily.com) 

Jupiter's polar cap is threaded in part with closed magnetic field lines rather than entirely with open magnetic field lines, new research finds.

New study ties solar variability to the onset of decadal La Nina events      (via sciencedaily.com) 

A new study shows a correlation between the end of solar cycles and a switch from El Nino to La Nina conditions in the Pacific Ocean, suggesting that solar variability can drive seasonal weather variability on Earth.

New statistical method eases data reproducibility crisis      (via sciencedaily.com) 

A reproducibility crisis is ongoing in scientific research, where many studies may be difficult or impossible to replicate and thereby validate, especially when the study involves a very large sample size. Now researchers have developed a statistical tool that can accurately estimate the replicability of a study, thus eliminating the need to duplicate the work and effectively mitigating the reproducibility crisis.

Scientists discover a new auroral feature on Jupiter      (via sciencedaily.com) 

Astronomers have detected new faint aurora features, characterized by ring-like emissions, which expand rapidly over time. Scientists determined that charged particles coming from the edge of Jupiter's massive magnetosphere triggered these auroral emissions.
