Using the Lulin One-meter Telescope (LOT), astronomers have observed a newly detected candidate ultra-faint dwarf galaxy known as Virgo III. As a result, they discovered three new RR Lyrae variable stars in the vicinity of ...
Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in this new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable ...

Using the Indian Astronomical Observatory (IAO) and ESA's Gaia satellite, astronomers have explored a galactic globular cluster known as NGC 2419. Results of the study, published April 29 on the preprint server arXiv, shed ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have observed a young star designated HD 21997. Results of the new observations indicate that the studied object is a high-frequency Delta Scuti pulsator. ...
Astronomers from the University of Warsaw, Poland and elsewhere have detected a new classical Cepheid variable star. The newfound star, which received designation OGLE-GD-CEP-1884, has the longest pulsation period known among ...
FS Tau is a multi-star system made up of FS Tau A, the bright star-like object near the middle of the image, and FS Tau B (Haro 6-5B), the bright object to the far right that is partially obscured by a dark, vertical lane ...

An international team of astronomers has performed spectroscopic observations of a variable star known as V708 Car. Results of the observational campaign, reported in a paper published February 20 on the pre-print server ...
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 ...
Perhaps the greatest and most frustrating mystery in cosmology is the Hubble tension problem. Put simply, all the observational evidence we have points to a universe that began in a hot, dense state, and then expanded at ...
