Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new, warm Jupiter-sized exoplanet orbiting a dwarf star. The newfound alien world, designated TOI-4127 b, is more ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected a new exoplanet orbiting a distant star. The newfound alien world, designated TOI-4603 b is the size of Jupiter and about 13 times more ...
By analyzing the data from the Hubble Space Telescope (HST), astronomers from the University of Bologna in Italy and elsewhere have found that the millisecond pulsar PSR J1835−3259B has a young white dwarf companion. The ...
A white dwarf star can explode as a supernova when its mass exceeds the limit of about 1.4 solar masses. A team led by the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching and involving the University of ...

Using data from NASA's Kepler spacecraft, astronomers from the Pedagogical University of Cracow, Poland, and elsewhere have detected 278 variable stars in the open cluster NGC 6791 and its surroundings. The finding was reported ...
Using the Guillermo Haro Observatory (OAGH) in Mexico, astronomers have performed spectroscopic observations of a dwarf nova known as U Geminorum. Results of the observational campaign, published March 10 on the arXiv pre-print ...
One of the first practical applications of the much-hyped but little-used quantum computing technology is now within reach, thanks to a unique approach that sidesteps the major problem of scaling up such prototypes.
