As NASA reports, two astronomers working with raw Webb data the space agency periodically makes available to researchers, ...

Astronomers have been aware of cosmic vampires, dead stars that hungrily strip plasma from victim stars, for some time. New ...

We measure the extremely long distances between things in space by light years. A light year is the distance that light travels in one Earth year. Light travels at about 300,000 kilometres per second.

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

Dark matter remains one of science's deepest mysteries. It makes up about 25% of our universe, yet scientists only observe ...

This lifespan began roughly 4.6 billion years ago, and will continue for about another 4.5 - 5.5 billion years, when it will deplete its supply of hydrogen, helium, and collapse into a white dwarf.

NASA's James Webb Space Telescope has been unwaveringly focused on our universe. With its unprecedented power to detect and analyze otherwise invisible infrared light, Webb is making observations that ...

This allows the white dwarf to survive with a small "endoparasitic" black hole (EBH) at its center. From the outside, the star may seem normal—but deep inside, a silent transformation is underway.

The true nature of dark energy is still being debated, but the newly observed diversity of white dwarf explosions may lead to a better understanding of the concept. The nearly 4,000 supernovae events ...

The researchers estimated that the white dwarf is orbiting the black hole at about 5% the distance that separates Earth from the sun, or a bit under 8 million kilometers.
