A tiny right before sunrise on July 4, A.D. 1054, imperial astronomers of the Track Dynasty in China noticed an unfamiliar star lights up the eastern sky. “It’s as vibrant as Venus, with pointed rays in all four instructions and a reddish-white color,” they wrote in notes delivered to the […]

‘Antistars’ Made of Antimatter Get a Particle’s Worth of Evidence
Antimatter may perhaps appear to be like the things of science fiction—especially due to the fact scarcely any of it can be observed in our universe, inspite of physicists’ very best theories suggesting antimatter should really have arisen in equal proportion to standard make a difference throughout the massive bang. […]
Searching for the Universe’s Most Energetic Particles, Astronomers Turn on the Radio
At any time due to the fact their discovery in the 1960s, ultrahigh-vitality cosmic rays have captivated researchers, who wonder in which they arrive from. Like all cosmic rays, they are arguably misnamed: they are not “rays” of radiation but somewhat subatomic particles, this sort of as protons or even […]
Method offers inexpensive imaging at the scale of virus particles | MIT News
Using an normal gentle microscope, MIT engineers have devised a system for imaging biological samples with accuracy at the scale of 10 nanometers — which should permit them to image viruses and most likely even solitary biomolecules, the scientists say. The new approach builds on enlargement microscopy, an strategy that […]
Identical Quantum Particles Pass Practicality Test
Quantum particles are recognized to be weird or even “spooky.” But can all those attributes at any time be useful? A new review proves that just one sort of wackiness—entanglement among equivalent particles—has practical value. Ordinarily, two objects are hardly ever particularly alike. They can only seem to be that […]
