Using ESA's Gaia satellite, astronomers have detected 87 stellar streams associated with globular clusters (GCs) in our Milky Way galaxy. The discovery, which doubles the number of known GC stellar streams, was detailed in ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers from the University of California, Irvine (UCI) and elsewhere, have discovered two new exoplanets orbiting M-dwarf stars. The newfound alien worlds are ...

Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/sub-millimeter Array (ALMA), an international team of astronomers has carried out comprehensive multiwavelength observations of a distant massive ...

Using the James Webb Space Telescope (JWST), astronomers have performed infrared observations of a planetary debris disk around a nearby white dwarf known as GD 362. Results of the new observations, presented October 8 on ...

Using ESA's Gaia satellite and NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers from the Ege University in Turkey and elsewhere have observed a galactic open cluster known as NGC 2506. Results of the observational ...

By analyzing the available data from various space observatories and ground-based telescopes, Indian astronomers have conducted a long-term multiwavelength study of a changing-look active galactic nucleus (AGN) known as NGC ...

Using various space telescopes, an international team of astronomers have observed a newly detected very faint X-ray transient designated 4XMM J174610.7–290020. Results of the observational campaign, published October 2 on ...

An international team of astronomers has used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a well-known quasar known as the Cloverleaf. As part of the observations, they serendipitously discovered a ...

Using ESA's XMM-Newton satellite, astronomers have conducted deep observations of a massive galaxy known as NGC 5746. As a result, they detected a hot gaseous outflow in the galaxy. The new findings, presented Oct. 1 on the ...

Astronomers from Australia and Serbia have performed multi-band photometric observations of a binary star known as V717 Andromedae. The observations yielded crucial information regarding the properties of V717 Andromedae, ...
