In recent years, certain luminous extragalactic optical transients have been observed to last only a few days. Their short observed duration implies a different powering mechanism from the most common luminous extragalactic transients (supernovae), whose timescale is weeks. Some short-duration transients, most notably AT2018cow (ref.

- Type Ia supernovae are crucial for understanding the accelerated expansion of the Universe, yet many details about their origins and explosions remain unclear.
- Researchers believe these explosions result from white dwarfs in binary systems, but the nature of their companions is still uncertain.
- The study of supernova SN 2011fe in the galaxy M101 suggests its progenitor was likely a carbon-oxygen white dwarf with a main-sequence companion, confirmed by spectroscopic observations and pre-explosion images.
