Primary instrument for NASA's Roman completed, begins tests

A team of engineers and technicians at Ball Aerospace, one of the industry partners for NASA's Nancy Grace Roman Space Telescope, and NASA's Goddard Space Flight Center in Greenbelt, Maryland, has finished assembling the ...

The search for the missing gravitational signal

Every year, hundreds of thousands of pairs of black holes merge in a cosmic dance that emits gravitational waves in every direction. Since 2015, the large ground-based LIGO, Virgo and KAGRA interferometers have made it possible ...

FAST telescope reveals unprecedented details of the Milky Way

The Milky Way is our home galaxy in the vast universe, but the structure and composition of the Milky Way remain mysterious. The vast interstellar space between the billions of stars is not empty, but filled with tenuous ...

Investigating the resonant two-photon ionization of helium

Using a new experimental method, physicists from the Max Planck Institute for Nuclear Physics in Heidelberg investigated the resonant two-photon ionization of helium with improved spectral resolution and angular resolution. ...

Creating the world's largest SiC aspherical mirror

Aspherical components in optical systems can increase the free design variables without introducing new aberrations. That brings improved imaging quality and reduced size and weight. Aspheric components are widely used in ...

X-ray light catchers for space just got a whole lot lighter

A team led by scientists from Tokyo Metropolitan University have created unprecedentedly lightweight optics for X-ray space telescopes, breaking the traditional trade-off between angular resolution and weight. They used Micro ...
