Could time itself actually explain our universe's expansion? Our current cosmological model—known as lambda cold dark matter, ...

Designated SN 2023adsy, the newfound stellar explosion is the most distant Type Ia supernova so far detected. The finding was detailed in a research paper published June 7 on the pre-print server ...

All supernovae are exploding stars. But the nature of a supernova explosion varies quite a bit. One type, named Type 1a supernovae, involves a binary star where one of the pair is a white dwarf.

Type Ia supernovae (SNe Ia) are a significant area of study in astrophysics, primarily because they serve as crucial tools for measuring cosmic distances and understanding the expansion of the ...

A new study of 1,535 Type 1a supernovae—a celestial object commonly used for analyzing the expansion of the universe—reports that this “lumpy” universe theory better explains new observati ...
