WebThese supernovae occur about once every 50 years in our Milky Way galaxy. But evidence shows that type Ia supernovae originate from some binary star systems that contain at least one white dwarf – the small, hot core remnant of a Sun-like star. WebSince the supernova event occurs when the star reaches a predictable mass, the luminosity of the type 1a supernova is also highly predictable, and they can thus be used as standard …

Their brightness as seen from Earth provides a cosmic yardstick, used among other things to discover "dark energy," the unknown force that is accelerating the expansion of the universe. Webbrightness (we say they are “standard candles”) then their measured apparent brightness tells us their relative distance. The measured redshift z is related to the scale factor by 1+z = 1/a (Liddle 2003, section A2.1), and the relationship between distance and z can be used to determine the values of ΩM,0 and ΩΛ,0. galaxy watch tide face
