(Phys.org) —It's been a busy week for space scientists—a team of astronomers discovered the first Thorne-Zytkow object—it's a weird type of hybrid between a red supergiant and a neutron star that looks like a regular ...
Using the James Webb Space Telescope, astronomers have conducted near- and mid-infrared observations of an extremely metal-poor blue compact dwarf galaxy known as I Zwicky 18. Results of the observational campaign, presented ...
Using the Himalayan Chandra Telescope (HCT) and ESA's Gaia satellite, Indian astronomers have conducted a comprehensive study of a young open cluster designated NGC 2345. Results of the study, presented March 7 on the preprint ...
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 the Caucasian Mountain Observatory (CMO), Russian astronomers have observed a peculiar infrared source designated IRAS 07253-2001. Results of the observational campaign, published July 20 on the preprint server arXiv, ...
An international research team led by the University of Minnesota Twin Cities has measured the size of a star dating back 2 billion years after the Big Bang, or more than 11 billion years ago. Detailed images show the exploding ...

An international team of astronomers reports the detection of a new supergiant fast X-ray transient with the Monitor of All-sky X-ray Image (MAXI) instrument. The newfound transient, designated MAXI J0709−159, was identified ...
Astronomers from the University of La Laguna, Spain and elsewhere have performed spectroscopic observations of an early B-type supergiant star known as 2MASS J20395358+4222505. Results of this observational campaign, published ...
Based on the results from a set of telescopes, astronomers detected X-ray variability of the source AX J1949.8+2534 and confirmed that the object is a supergiant fast X-ray transient (SFXT). The finding is reported in a paper ...
European astronomers have investigated a recently discovered hard X-ray transient known as IGR J17503-2636 using space observatories. Results of this study, presented in a paper published March 7 on the arXiv pre-print server, ...
