But the nature of a supernova explosion varies quite a bit . One type , named Type 1a supernovae , involves a binary star where one of the pair is a white dwarf . And while supernovae of all types usually involve a single explosion , astronomers have found something that breaks that mould : A Type 1a supernova that may have detonated twice . Type 1A supernovae occur in binary stars where one star is a white dwarf , and the other star is anything

Using the Australian Square Kilometer Array Pathfinder (ASKAP), an international team of astronomers has serendipitously detected a new Galactic supernova remnant (SNR), which received designation SNR G288.8–6.3. The finding was reported in a paper published August 17 on the pre-print server arXiv.

Neutrinos are tiny and neutrally charged particles accounted for by the Standard Model of particle physics. While they are estimated to be some of the most abundant particles in the universe, observing them has so far proved to be highly challenging, as the probability that they will interact with other matter is low.
