(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 ...
In a discovery decades in the making, scientists have detected the first of a "theoretical" class of stars first proposed in 1975 by physicist Kip Thorne and astronomer Anna Żytkow. Thorne-Żytkow objects (TŻOs) are hybrids ...

A trio of researchers at The University of Tokyo has found that data from weather satellites can be used to study the stars. In their paper published in the journal Nature Astronomy, Daisuke Taniguchi , Kazuya Yamazaki ...
For the very first time, astronomers have imaged in real time the dramatic end to a red supergiant's life, watching the massive star's rapid self-destruction and final death throes before it collapsed into a Type II supernova.

Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in measuring their temperatures. For the first time, astronomers have ...

Late last year, news broke that the star Betelgeuse was fading significantly, ultimately dropping to around 40% of its usual brightness. The activity fueled popular speculation that the red supergiant would soon explode as ...

Using ESO's Very Large Telescope (VLT), astronomers have captured the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation of Orion. The stunning new images of the star's surface show not only the ...

Astronomer J. Craig Wheeler of The University of Texas at Austin thinks that Betelgeuse, the bright red star marking the shoulder of Orion, the hunter, may have had a past that is more interesting than meets the eye. Working ...
