A 3-D model of stellar core collapse

(Phys.org) —What happens when massive stars collapse? One potential result is a core-collapse supernova. Astronomers can make observations of such events that tell us what is happening on the surface of a star when it explodes ...

Red Crucifix sighting in 774 may have been supernova

(Phys.org) -- A supernova may have actually been the mysterious "Red Crucifix" in the sky that is cited in the Anglo Saxon Chronicle for the year 774. New correspondence between a university student and Nature carries interesting ...

Evidence found of white dwarf remnant after supernova

An international team of space scientists has found evidence of what they believe is a remnant of a type Iax supernova—a white dwarf moving in a way that suggests it was blown across part of the universe by the power of ...

Astronomers glimpse supernova shockwave

Astronomers have captured the earliest minutes of two exploding stars and for the first time seen a shockwave generated by a star's collapsing core.

Could this rare supernova resolve a longstanding origin debate?

Detection of a supernova with an unusual chemical signature by a team of astronomers led by Carnegie's Juna Kollmeier—and including Carnegie's Nidia Morrell, Anthony Piro, Mark Phillips, and Josh Simon—may hold the key ...

Active galaxies point to new physics of cosmic expansion

Investigating the history of our cosmos with a large sample of distant 'active' galaxies observed by ESA's XMM-Newton, a team of astronomers found there might be more to the early expansion of the universe than predicted ...
