Hubble captures giant star on the edge of destruction
The expanding shell of gas and dust that surrounds the star is about five light-years wide, which equals the distance from here to the nearest star beyond the Sun, Proxima Centauri.

Using the ARIES telescope, astronomers from India have inspected a young open cluster known as NGC 281, searching for new variable stars. As a result of this investigation, they detected 228 new variables. The finding is ...
Astronomers from India have conducted a long-term photometric variability survey of an open cluster known as NGC 559. As a result, they detected 70 new variable stars in the field of this cluster. The finding is presented ...
Chinese astronomers have conducted a study of variable stars in the galactic open cluster NGC 1912 and its surrounding field, detecting 11 new variables in this cluster, including binary systems. The study was detailed in ...
Using the European Southern Observatory's Very Large Telescope (VLT), astronomers have discovered the absence of an unstable massive star in a dwarf galaxy. Scientists think this could indicate that the star became less bright ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected Beta Cephei-type pulsations in an eclipsing binary system known as V453 Cygni. The finding, detailed in a paper published May 15 on arXiv.org, ...
Using three ground-based telescopes, astronomers have conducted a long-term photometric monitoring of the Sh 2-170 star-forming region. The new observations have identified 71 variable stars in this region and provided essential ...
Indian astronomers have conducted a comprehensive photometric, kinematic and variability study of a young open cluster known as NGC 1960. Results of the research shed more light on the properties of this cluster and its member ...
Using ESA's XMM-Newton spacecraft, astronomers have conducted X-ray observations of a peculiar Cepheid variable star known as V473 Lyr. Results of the study suggest that this star has a young, low-mass companion. The finding ...
The interiors of stars are largely mysterious regions because they are so difficult to observe directly. Our lack of understanding about the physical processes there, like rotation and the mixing of hot gas, introduces considerable ...
