An international team of astronomers has employed the James Webb Space Telescope (JWST) to conduct near-infrared imaging of GN-z11—one of the most distant galaxies known to date. Results of these observations yield important ...
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have detected a new galaxy, which received designation FAST J0139+4328. The newfound galaxy is isolated, has a relatively low stellar ...
Using NASA's Kepler spacecraft and Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new Earth-sized exoplanet located about 70 light years away from the sun. The newfound exoworld, designated K2-415b, ...
One of the most intriguing predictions of Einstein's general theory of relativity is the existence of black holes: astronomical objects with gravitational fields so strong that not even light can escape them.
