Not all stars are created equally. Astronomers believe that the first stars to form after the Big Bang were mostly made of ...

Some classes of stars create light elements, such as oxygen and silicon; others also craft heavier ones, such as iron and ...

A companion star may have stripped silicon layers. This provided a new window into stellar death. Astronomers have observed the inner layers of a dying star through a rare type of stellar explosion ...

Astronomers have recently uncovered an extraordinary star, SDSS J0715-7334, which may be the most “pristine” object ever ...

Scientists found that carbon enabled Earth’s core to solidify. Without it, the inner core may not exist. A team of scientists ...

NASA's Perseverance rover has found minerals that could have powered life on Mars — or simply shaped the Red Planet's ...

LIGO's 2015 detection confirmed Einstein's theory and sparked a decade of data. Upgraded LIGOs now detect black hole mergers every three days with precision. New 2025 findings confirmed Hawking’s ...

The James Webb Space Telescope has spotted a giant protostar blasting jets, seen diagonally here, on the edge of the Milky Way. Credit: NASA / ESA / CSA / STScI / Yu Cheng / Joseph DePasquale In a ...

LIGO observatory near Richland confirmed Einstein’s theory of relativity, it also has proven one of Hawking’s theorems.

Stephen Hawking was immediately on the phone in 2015 when he learned that the Hanford LIGO observatory in Eastern Washington and its twin observatory in Louisiana had made the first-ever direct ...

In theory, a white dwarf can have a mass of up to 1.4 times that of the Sun, but white dwarfs heavier than the Sun are rare. These objects, which astronomers call ultra-massive white dwarfs, can form ...

It might sound hard to believe, but NASA's exoplanet count just reached 6,000 — and that's with only about 30 years of hunting worlds beyond our solar system. In fact, only three years ago, that ...
