Using the Spektr-RG (SRG) space observatory, astronomers from the Russian Academy of Sciences have investigated dozens of X-ray sources in all-sky surveys, which resulted in the detection of 11 new active galactic nuclei. ...

An international team of astronomers reports the discovery of two new exoplanets, a few times more massive than Earth, orbiting a sun-like star known as HD 35843. The finding was reported in a research paper published May ...

Japanese astronomers have presented new results of observations that suggest an unidentified X-ray source designated AX J145732−5901 is a cluster of galaxies behind the galactic plane. The findings are detailed in a research ...

Astronomers have employed the Nuclear Spectroscopic Telescope Array (NuSTAR) and the Neutron Star Interior Composition Explorer (NICER) to observe the X-ray pulsar RX J0032.9-7348 in a broadband X-ray energy range. Results ...

Using the NOrthern Extended Millimeter Array (NOEMA) and the Atacama Large Millimeter/submillimeter Array (ALMA), Chinese astronomers have observed a young stellar object known as G24.33+0.14 in the process of cooling after ...

Using the 104-cm Sampurnanand optical telescope, Indian astronomers have performed photometric observations of an open cluster named King 6, which resulted in the detection of three new variable stars in the field of this ...

Using the Neutron star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), astronomers have observed IGR J12580+0134, which is the closest tidal disruption event. Results of the observational ...

By analyzing the data from the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have investigated a star-forming region known as G34.26+0.15. As a result, they discovered an explosive outflow in this complex. ...

Using the Spektr-RG (SRG) space observatory, astronomers from the Russian Academy of Sciences have inspected a radio-loud quasar known as SRGA J2306+1556, which is extremely luminous in the X-ray band. Results of the new ...

Using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), Chinese astronomers have discovered a new millisecond pulsar. The newfound pulsar, designated PSR J2129-1210O, was missed by previous searches as its ...

Using the Australian Square Kilometer Array Pathfinder (ASKAP), astronomers have discovered 15 new giant radio galaxies with physical sizes exceeding 3 million light years. The finding was reported in a research paper published ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers have detected a new sub-Neptune exoplanet orbiting a bright G-type star. The newfound alien world, designated TOI-3493 b is more ...

Using the Australia Telescope Compact Array (ATCA) and Parkes 64-m telescope, an international team of astronomers has performed a radio continuum study of MC SNR J0519–6902—a supernova remnant in the Large Magellanic Cloud ...

By analyzing the available observational data, astronomers from the Tribhuvan University in Nepal and elsewhere have investigated the properties of a compact dwarf galaxy designated SDSS J134313.15+364457.5 (or J1343+3644 ...

Using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), Indian astronomers have observed an X-ray binary system designated SXP 138. Results of the NuSTAR observations, published March 26 on thearXiv pre-print server, ...
