NASA announced Tuesday it selected a new instrument to study the sun and how it creates massive solar eruptions. The agency’s Joint EUV coronal Diagnostic Investigation, or JEDI, will capture images of the sun in extreme ultraviolet light, a type of light invisible to our eyes but reveals many of the underlying mechanisms of the […] NASA’s Psyche spacecraft passed its six-month checkup with a clean bill of health, and there’s no holding back now. Navigators are firing its futuristic-looking electric thrusters, which emit a blue glow, nearly nonstop as the orbiter zips farther into deep space. Go to Source Huge black holes are firing powerful beams of particles into space—and then changing their aim to fire at new targets. This discovery, made using NASA’s Chandra X-ray Observatory and the U.S. National Science Foundation (NSF) National Radio Astronomical Observatory’s (NRAO) Very Long Baseline Array (VLBA), shows what kind of widespread impact black holes can have […] France’s Sophie Adenot and Belgium’s Raphael Liegeois will be the first two from a new class of European astronauts to blast off to the International Space Station, the European Space Agency said Wednesday. Go to Source University of Michigan physicists have devised a way to manipulate active fluids, a type of fluid composed of individual units that can propel themselves independently, by taking advantage of topological defects in the fluids. Go to Source An international research team including Los Alamos National Laboratory and Tel Aviv University has developed a unique, mechanical metamaterial that, like a computer following instructions, can remember the order of actions performed on it. Named Chaco, after the archaeological site in northern New Mexico, the new metamaterial offers a route to applications in memory storage, […] Light measurement devices called optical frequency combs have revolutionized metrology, spectroscopy, atomic clocks, and other applications. Yet challenges with developing frequency comb generators at a microchip scale have limited their use in everyday technologies such as handheld electronics. Go to Source A study now published in Nature Communications brings remarkable insights into the enigmatic behavior of supercritical fluids, a hybrid state of matter occupying a unique space between liquids and gases, and arising in domains that go from the pharmaceutical industry to planetary science. The obtained results are at the limit of current experimental possibilities and […] The child and his mother had been held hostage by the mother’s ex-boyfriend for several hours before the police standoff began Go to Source In the rapidly evolving field of photonics, an advancement has emerged from Korea, redefining the possibilities of structural color manipulation. Scientists have developed a pioneering technology capable of omnidirectional wavelength tuning, which promises to revolutionize a myriad of tunable photonic applications. Go to Source The man, who was suffering a mental health crisis, hurled threats at officers as he ran toward them with knife and hammer raised Go to Source Warwick Police Chief David Shoemaker was assisting a sergeant with a traffic stop when the driver involved in the stop hit Shoemaker with his car twice Go to Source The sun’s surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed that the sun’s field is generated deep within the star. But an MIT study finds that the sun’s activity may be shaped by a much […] Astronomers at MIT, NASA, and elsewhere have a new way to measure how fast a black hole spins, by using the wobbly aftermath from its stellar feasting. Go to Source For the first time, scientists have observed plasma waves from a solar flare focused by a coronal hole, akin to the focusing of sound waves responsible for the Rotunda effect in architecture or the focusing of light by a telescope or microscope.
