Using various space telescopes, European astronomers have performed deep X-ray and radio observations of a young magnetar known as Swift J1818.0–1607 during its outburst. Results of the observational campaign, published ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected solar-like oscillations and ellipsoidal variations in the light curve of a binary system known as 12 Boötis (or ...
Scientists have found a way to "see" inside deuterons, the simplest atomic nuclei, to better understand the "glue" that holds the building blocks of matter together. The new results come from collisions of photons (particles ...
