Using various space observatories, astronomers have performed X-ray polarimetric and spectral observations of a bright low-mass X-ray binary known as Serpens X-1. Results of the observational campaign, published August 29 ...

Astronomers from the Special Astrophysical Observatory (SAO) in Russia and elsewhere report the discovery of a new cataclysmic variable system, designated SRGe J194401.8+284452, which is located some 1,350 light years away. ...

Researchers have conducted detailed infrared observations of a recently formed stellar cluster in a giant molecular cloud designated G148.24+00.41. Results of the observational campaign, presented in a research paper published ...

Using the Circumgalactic H-alpha Spectrograph (CHαS), astronomers have performed spectroscopic observations of a nearby active galaxy designated Messier 77. They detected a very extended structure of ionized gas around this ...

Astronomers have performed photometric observations of a young globular cluster known as NGC 1851. The new observational campaign provides more insights into the variable star population of this cluster and validates the ...

Using ESA's Gaia satellite, astronomers have serendipitously discovered a new open cluster in the Milky Way galaxy. The newfound cluster, which received the designation Ash-1, is relatively young and consists of at least ...

An international team of astronomers reports the discovery of a new hyperluminous quasar. The newfound quasar, which received the designation eFEDSJ0828–0139, has a high star-formation rate and its black hole is accreting ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby spiral galaxy known as NGC 891. Results of the observational campaign, published August 15 on the preprint server arXiv, ...

An international team of astronomers reports a serendipitous discovery of a new radio ring toward the Galactic center. The newfound object is relatively faint and its true nature is yet unknown. The finding was reported in ...

Chinese astronomers have conducted multi-frequency polarimetric observations of a quasar known as 1604+159. Results of the observational campaign, published August 13 on the pre-print server arXiv, shed more light on the ...

Chinese astronomers have performed multi-wavelength observations of a galactic supernova remnant known as HB9. Results of the observational campaign, published August 9 on the preprint server arXiv, shed more light on the ...

By analyzing the images obtained with the James Webb Space Telescope (JWST), an international team of astronomers has managed to identify more than 1,000 new star cluster candidates in the Cigar Galaxy. The finding was reported ...

An international team of astronomers has reported the discovery of a new brown dwarf, which received designation TOI-2490 b. The newfound object is about 74 times more massive than Jupiter and orbits a sun-like star on a ...

An international team of astronomers reports the detection of a blazar with highly significant sinusoidal radio variability using the Owens Valley Radio Observatory (OVRO). The finding was detailed in a research paper published ...

Astronomers from the Pennsylvania State University (PSU) and elsewhere have observed an X-ray binary system known as CXOU J005245.0-722844. They detected an X-ray outburst from this binary and found that it harbors a white ...
