Type Ia supernovae originate in binary star systems—systems where two stars orbit each other. In one possible scenario, there are two stars approximately the same size—let's say about the size ...

A 3-D map of the strange remains of a supernova seen in 1181 traces the odd tendrils of gas that jut out for several light-years in all directions.

Looking for efficiency and accuracy, Brout fills up his supernova collection by employing machine learning algorithms that vigorously scout out as many Type 1a's as possible. (Yet another reason ...

Because Type Ia supernovae always explode at 1.4 solar masses, they all have more or less the same characteristics, including how brightly they shine.

Such core-collapse supernovae are responsible for producing the cosmos’ predominantly lighter metals --- from oxygen to silicon and sulfur. In contrast, so-called Type 1a supernovae are ...

Both Requiem and Encore are Type 1a supernovae, or “standard candles” with known absolute magnitudes, allowing astronomers to know their distance. Because their distance can be calculated ...

This white dwarf collision will trigger a specific type of supernova called type 1a that always produces the same amount of light. Astronomers can tell how far away each type 1a supernova is by ...
