Using the upgraded Giant Metrewave Radio Telescope (uGMRT), astronomers have performed radio observations of the Ophiuchus galaxy cluster. Results of the observations, published August 26 in The Astrophysical Journal, deliver ...
Astronomers from Yonsei University in Seoul, South Korea, and elsewhere report the discovery of a new isolated early-type dwarf galaxy, which appears to have run away from the group environment. The finding is detailed in ...
Astronomers have performed radio observations of WTP 14adeqka—a tidal disruption event discovered a decade ago. Results of the observational campaign, published August 22 on the pre-print server arXiv, provide crucial insights ...
All (or at least most) astronomical eyes are on 3I/ATLAS, our most recent interstellar visitor that was discovered in early July. Given its relatively short observational window in our solar system, and especially its impending ...

By analyzing the available optical spectroscopic data, astronomers have investigated a nearby planetary nebula designated IC 418, also known as the Spirograph Nebula. Results of the study, published August 20 in The Astrophysical ...
Astronomers from Argentina and Spain have performed near-infrared observations of a massive young stellar object known as MYSO G29.862−0.0044. The observational campaign sheds more light on the nature of this object and ...
Using NASA's James Webb Space Telescope, a team led by the Southwest Research Institute (SwRI) has identified a previously unknown moon orbiting Uranus, expanding the planet's known satellite family to 29. The detection was ...
