Eternal Flames: Unraveling the Mystery of Delayed White Dwarfs
Researchers discovered why some white dwarfs remain luminous for billions of years: a core process where lighter crystals rise and denser liquids sink, balancing the…

When a star like our Sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it….
Astronomers using Georgia State’s CHARA Array have detected the faint light of stellar corpses beside predator stars. Scientists working with the powerful telescopes at Georgia…
New types of stars, including ‘old smokers’ and erupting protostars, have been discovered in the Milky Way. This research, using advanced telescopes, challenges existing theories…
Through the study of detailed data obtained from a powerful ten-meter telescope located in Hawaii, a team of scientists at Lund University in Sweden have…
A newly developed technique for estimating age reveals surprising findings about the formation and drifting apart of young stars. A team of astrophysicists led by…
Gyrochronology, a technique for estimating star ages based on rotation, has been extended from cluster stars to field stars, revealing consistent aging patterns and broadening…
New findings confirm existence of hot helium stars long-thought to be at the heart of hydrogen-poor supernovae and neutron star mergers. Astronomers at the University…
A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research…
Uncovering the missing precursors of hydrogen-poor supernovae. Supernovae–stellar explosions as bright as an entire galaxy–have fascinated us since time immemorial. Yet, there are more hydrogen-poor…
New study is the first to determine how much stars should innately twinkle. Many people know that stars appear to twinkle because our atmosphere bends…
Astronomers have mapped 39 interstellar clouds where high-mass stars are expected to form. This extensive data indicates that our current understanding of low-mass star creation…
The Universe is vast, encompassing hundreds of billions of galaxies. For those galaxies close to us, we primarily determine their distances using classical Cepheids and…
The Sh2-284 nebula, awash in vibrant hues of orange and red, is beautifully captured in intricate detail thanks to the VLT Survey Telescope at the…
Stars serve as the fundamental building blocks of galaxies and, by extension, the entire observable universe. Among the diverse spectrum of stars, those with a…
They also discovered a bright optical emission. Joseph Shklovsky, one of the pioneers of modern astrophysics, posited that a star’s existence is an eternal struggle…
Astrophysicists at the Flatiron Institute and their colleagues have created the first computer simulations showing how convection in the cores of massive stars generates waves…
Unusual white dwarf star is made of hydrogen on one side and helium on the other. In a first for white dwarfs, the burnt-out cores…
