An astronomer at the California Institute of Technology has discovered that some stars — maybe as many as 1 in 10,000 — are made entirely of metal. It’s the latest finding in a series of ...

That’s because a bar-shaped collection of stars at the center of the Milky Way appears to be much younger than expected. “These metal-rich stars are basically like fossil records of ancient ...

Astronomers have discovered ultra-weak magnetic fields in Beta Ursae Majoris and Theta Leonis, two metallic-line stars. Obtained from deep spectropolarimetric analysis, the results may be proof ...

Here we show that a metallic circular nanoscale aperture is a magnetic scatterer in complete agreement with Bethe's theoretical analysis on diffraction by a circular aperture 29, allowing the ...

A camera mounted on the International Space Station captured light from the stars to 'draw' these spectacular circular patterns as the spacecraft orbited the planet. Nasa flight engineer Don ...
