So far, astronomers have not directly spotted supergiant stars in the early universe.
Cygnus is one of the most recognizable constellations of the northern summer and autumn, featuring a prominent asterism known as the Northern Cross (in contrast to the Southern Cross), dominated by Deneb (Alfa Cygni), a blue - white supergiant star of visual magnitude 1.3, very bright despite its distance of some 3200 light year from Earth.
Thorne has carried out a wide range of theoretical research in gravitation and astrophysics, including having predicted the existence of a type of red supergiant star with a neutron star core, and using general relativity to describe how black holes move and precess.
«This alters our basic understanding of red - supergiant star atmospheres,» explains Lim.
When Population III stars matured into supergiant stars after a few million years of life or so, however, they blew off heavier elements in strong stellar winds, and many probably exploded as supernovae, contaminating the universe with richer gas and dust.
