Artist’s view of a watery asteroid heading to a white dwarf star.
The discovery of a white dwarf star with hydrogen and oxygen in its atmosphere suggests water could be planted on stars and planets by bodies like asteroids.
Artist’s impression of two white dwarf stars destined to merge and create a Type Ia supernova in 700-million years time.
Two white dwarfs found orbiting each other at the centre of a planetary nebula are now known to have enough mass that they will eventually trigger a special kind of supernova, according to research published…
