Astronomers from Curtin University in Australia and elsewhere report the detection of a new supernova remnant (SNR) located some 3,300 light years away. The newfound SNR, designated G321.3-3.9, has an elliptical shape and ...

By analyzing the data from the Neutron star Interior Composition Explorer (NICER), astronomers from the Physical Research Laboratory (PRL) in Ahmedabad, India and elsewhere, have performed a detailed X-ray timing and spectral ...

Astronomers have conducted spectroscopic and photometric observations of a peculiar pulsating variable white dwarf known as TMTS J17184064+2524314. Results of the observational campaign, published January 26 on the preprint ...

An international team of astronomers has conducted multiwavelength observations of AT 2023clx—the closest to Earth tidal disruption event (TDE). Results of the observational campaign, published Jan. 22 on the pre-print server ...

Using XMM-Newton, Chandra and NuSTAR space telescopes, an international team of astronomers has explored the nature of a recently-detected very-high-energy source designated 2FHL J1745.1–3035. Results of the study, published ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new ultra-short-period exoplanet. The newfound alien world, designated Wolf 327 b, is slightly larger and about ...

A team of Russian astronomers from the Pushchino Radio Astronomy Observatory (PRAO) and elsewhere, reports the detection of 39 new pulsars as part of the Pushchino Multibeams Pulsar Search (PUMPS) project. The finding was ...

The nearby lenticular galaxy NGC 5252 hosts extremely extended cones of ionized material. Recent observations conducted by an international team of astronomers have inspected these remarkable structures, providing important ...

Using various ground-based facilities and space telescopes, astronomers have observed an accretion outburst that recently occurred on a young variable star known as V1741 Sgr. Results of the observations, published January ...

Using various ground-based telescopes, astronomers have performed photometric and spectroscopic observations of a nearby Type Ia supernova known as SN 2020nlb. Results of the observations campaign, presented January 16 on ...

Astronomers from Turkey and Russia have performed optical observations of a magnetic cataclysmic variable known as SRGA J213151.5+491400. Results of the observational campaign, presented Jan. 11 on the pre-print server arXiv, ...

An international team of astronomers reports the detection of a new tidal disruption event (TDE) as part of All-Sky Automated Survey for SuperNovae (ASAS-SN). The newfound TDE, designated ASASSN-23bd, turns out to be the ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered nine new "hot Jupiter" exoplanets. One of the newly detected alien worlds is almost four times more massive than ...

An international team of astronomers reports the discovery of a new cataclysmic variable. The newfound system, designated SRGeJ041130.3+685350 (or SRGeJ0411 for short), has an orbital period of about 100 minutes and may contain ...

Astronomers from the Open University in Milton Keynes, UK and elsewhere report the detection of a new Be/X-ray binary. The newfound system, designated 4XMM J182531.5–144036, exhibits persistent X-ray emission. The finding ...
