By analyzing the data from the JWST Advanced Deep Extragalactic Survey (JADES), an international team of astronomers has discovered a new quiescent galaxy. The newfound system, designated JADES-GS+53.12365-27.80454, turns ...

Using the Hubble Space Telescope (HST) and the Chandra X-ray Observatory, astronomers have taken a closer look at a short-period high-mass X-ray binary known as CXOU J121538.2+361921. Results of the observational campaign, ...

An international team of astronomers reports the discovery of a new "super-Earth" exoplanet with NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound alien world, designated TOI-1680 b, is about 50% larger than ...

Astronomers from the University of Washington in Seattle and elsewhere have conducted Hubble Space Telescope (HST) observations of the nearby Fireworks Galaxy. Results of the observational campaign, presented July 10 on the ...

Astronomers from the University of Science and Technology of China in Hefei report the discovery of a new faint tidal disruption event (TDE). The newfound TDE, designated AT 2023clx is the faintest and closest optical TDE ...

Using the 3.6-m New Technology Telescope (NTT) at the La Silla Observatory in Chile, astronomers have observed three peculiar white dwarfs of the DAHe subtype. In their results, they found dipolar chromospheres in two of ...

Using the upgraded Giant Meterwave Radio Telescope (uGMRT), astronomers from India and Australia have performed radio observations of a pulsar known as PSR J0026–1955. Results of the observational campaign, published July ...

Using NASA's Swift spacecraft, an international team of astronomers has discovered a luminous and slowly-evolving nuclear transient event. The origin of the newly detected transient, designated Swift J221951-484240, is yet ...

By analyzing the data from various ground-based facilities and space telescopes, European astronomers have investigated the nature of a peculiar object known as PM 1-322. As a result, they found evidence indicating that PM ...

Using NASA's Swift spacecraft, an international team of astronomers has carried out a long-term multiwavelength monitoring of a nearby active galaxy known as Markarian 817. Results of the observational campaign, published ...

An international team of astronomers reports the discovery of two new sub-Neptune exoplanets using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound alien worlds, designated TOI-2084 b and TOI-4184 b, orbit ...

Using ESA's Gaia satellite, Turkish astronomers from the Istanbul University have explored a Galactic open cluster known as Berkeley 6. Results of the study, published June 27 in the Bitlis Eren University Journal of Science, ...

Chinese astronomers have used the Hard X-ray Modulation Telescope (HXMT) to observe the latest outburst of a low-mass X-ray binary system known as GX 339-4. They detected new quasi-periodic oscillations in this source. Their ...

Using the Spektr-RG (SRG) spacecraft and the Zwicky Transient Facility (ZTF), an international team of astronomers has discovered a new eclipsing cataclysmic variable system, which received designation SRGeJ045359.9+622444 ...

Using the 4.3-m Lowell Discovery Telescope (LDT), astronomers Kathryn F. Neugent and Philip Massey, have observed the nearby Andromeda galaxy. In result, they detected 19 new Wolf-Rayet stars in this galaxy. The finding was ...
