This NASA/ESA Hubble Space Telescope Picture of the Week features the galaxy LEDA 22057, which is located about 650 million ...

This is particularly true for one particular kind of supernova known as Type Ia. An overview of the different proposed Type Ia supernova progenitors has been published on the arXiv preprint server.

The Hubble Space Telescope captures the mesmerizing galaxy LEDA 22057, home to a recent supernova explosion, SN 2024PI. This ...

Modern cosmology stands on the brink of a transformative era, where groundbreaking observational technologies redefine our ...

The cosmos began expanding with the Big Bang but then around 10 billion years later it strangely began to accelerate thanks ...

Their discovery would not have been possible without a special cosmic yardstick—exploding stars, or supernovae—specifically the variety known as Type Ia. Because Type Ia supernovae are visible ...

New research challenges dark energy's existence, suggesting the 'timescape model' better explains cosmic expansion through ...

A new class of X-ray explosions, 'millinovas,' has been identified, with bright emissions 100 times the Sun's output ...

That makes it the largest and arguably most successful supernova surveyor to date. "There are trillions of stars in the universe, and about every second, one of them explodes," California ...

A team of physicists and astronomers from the University of Canterbury in Christchurch, New Zealand, is challenging the ...

The research, based on enhanced light-curve analysis of "type Ia supernovae," suggests the universe expands in a "lumpy" and uneven manner rather than uniformly. Published Thursday in the journal ...
