Supernovae of this type help astronomers measure the distance to faraway galaxies. This is possible because Type Ia supernovae have the same intrinsic luminosity—no matter how bright they seem ...

Astrophysicists studying the early universe think planet formation didn’t begin in earnest until supernovae had released enough heavy elements to form planetesimals, the building blocks of rocky ...

Type Ia supernovae are valuable to astronomers because they serve as reliable cosmic yardsticks. They are believed to have a consistent intrinsic brightness, meaning they all emit the same amount of ...

These images show three of the supernovae identified in the JADES images. AT2023 ADS-V appears in the lefthand column, with a redshift (z) of 3.8, which indicates it occurred at a time when the ...

Shock breakout of hypernovae: Hypernovae are even more violent astronomical phenomena than supernovae, with explosion energies exceeding those of supernovae by more than ten times. These powerful ...

Scolnic and his team used the spectrum of wavelengths and intensities from the galaxies that matched those of a dozen Type Ia supernovae; the radiant death throes of stars blazing in a characteristic ...
