An international team of astronomers has conducted spectroscopic and photometric observations of a cataclysmic variable (CV) known as V1460 Her. Results of the study indicate that the system consists of a fast-spinning white ...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers from Japan have probed a nearby starburst galaxy known as NGC 1482. They detected a molecular gas outflow that could be essential to improving the ...
Recent observations of Betelgeuse have revealed that the star's unexpected and significant dimming periods in late 2019 and early 2020 were most likely caused by the ejection and cooling of dense hot gases, and that the star ...

Using the Spektr-RG (SRG) spacecraft, Russian astronomers have investigated a sample of distant quasi-stellar objects (QSOs), or quasars. They report the detection of strong X-ray emissions from such source designated CFHQSJ142952+544717, ...
Using the TIGRE telescope, astronomers have conducted spectroscopic observations of recently discovered nova known as V659 Sct during multiple phases of its outburst. Results of this observational campaign, presented in a ...
Astronomers from Malta and Spain have conducted an observational campaign aimed at investigating the periodic behavior of a carbon star known as CGCS 673. The observations found that the studied object is a semi-regular variable ...
Using NASA's Chandra X-ray Observatory and the Southern Astrophysical Research (SOAR) telescope, astronomers have conducted X-ray observations and near-infrared imaging of a protostar named HOPS 383. The monitoring campaign ...
When stars explode as supernovas, they produce shock waves in the plasma surrounding them. So powerful are these shock waves, they can act as particle accelerators that blast streams of particles, called cosmic rays, out ...
