Binary stars and their extraordinary lives
... medium with iron in the process. A merger between two white dwarfs may also trigger the same type of supernovae. Because of their homogeneity, these explosions can be used as ‘standard candles’ such that we can calculate their distance...

Mysterious Quark Nova lights up an exploding star for a second time
... of matter onto a companion star and as the matter reaches a critical limit, it ignites a series of runaway nuclear reactions. Type II supernovas occur when a star runs out of nuclear fuel and it collapses under its own gravity. What is left...

New physics needed to explain early expansion of the Universe
... as standard candles has great potential, since we can observe them out to much greater distances from us than type-Ia supernovas, and so use them to probe much earlier epochs in the history of the cosmos,” explains Lusso. So, using X-ray...

New measurement deepens mystery of Universe’s expansion rate
...a definitive figure for Hubble’s constant as the powerful space observatory aims to collect a wealth of information on new Type Ia supernovae, Cepheid variables, and red giant stars, amongst other celestial objects. Its Hubble-like resolution and ...
