Astronomers have recently observed a low-mass X-ray binary known as IGR J17407−2808 with NuSTAR and XMM-Newton space telescopes. In result, they detected several fast X-ray flares from this source. The finding was reported ...
A pair of anthropologists at Tulane University has solved the mystery of the Mayan 819-day count, a type of ancient Mesoamerican calendar system. In their paper published in the journal Ancient Mesoamerica, John Linden and ...
By analyzing the data from the 104-cm Sampurnanand Telescope (ST) and ESA's Gaia satellite, astronomers from India have inspected a Galactic open cluster known as NGC 1027. Results of the study, published April 12 on the ...
Astronomers have investigated an ultraslow radio pulsar known as PSR J0901-4046, finding that it has an extremely high magnetic field—at a level of 30 quadrillion Gauss. The discovery, published April 7 in Physical Review ...
After upgrading the radio telescope array at Westerbork, The Netherlands, astronomers have found five new fast radio bursts. The telescope images, much sharper than previously possible, revealed that multiple bursts had pierced ...

Using the Tillinghast Reflector Echelle Spectrograph (TRES) and the Transiting Exoplanet Survey Satellite (TESS), astronomers from the Harvard-Smithsonian Center for Astrophysics (CfA) have detected an M-dwarf companion to ...
By analyzing the data from various astronomical surveys, astronomers have detected 188,002 candidate metal-poor stars. The discovery, reported in a research paper published March 30 on the arXiv pre-print server, may help ...
Using AstroSat and NuSTAR space telescopes, astronomers have observed an X-ray binary known as XTE J1739−285 during its recent period of bursting activity. Results of the observational campaign, published March 23 on the ...
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 ...
