An international team of astronomers and astrophysicists studying data and imagery received from the James Webb Space Telescope (JWST) has found that light emitted from one of the earliest galaxies identified thus far, is ...
Astronomers have employed NASA's Transiting Exoplanet Survey Satellite (TESS) to observe a subdwarf star designated TIC 441725813. In result, they found that TIC 441725813 is a hybrid hot B subdwarf pulsator. The discovery ...
Astronomers have recently found hundreds of "polluted" white dwarf stars in our home galaxy, the Milky Way. These are white dwarfs caught actively consuming planets in their orbit. They are a valuable resource for studying ...

Using the MeerKAT radio telescope, astronomers have observed eclipses in the radio emission of a pulsar known as PSR J0024−7204O. Results of the observational campaign, published on the preprint server arXiv, could help ...
By diving into the sun's corona, NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause of the corona's searing temperatures, according to University of Michigan research published in ...
