A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.

Earth and the entire Milky Way galaxy might be sitting inside an enormous, mysterious void—a giant cosmic hole making our universe expand faster right here than anywhere else. This unusual idea, ...

Recent astronomical research indicates that our Earth may be embedded within one of the largest known structures in the observable universe. Scientists have identified a vast ring of galaxies that ...

How space telescopes capture distant galaxies using infrared imaging, precision optics, and astronomy technology beyond Earth's atmosphere.

The James Webb Space Telescope has detected the most distant galaxy ever observed, MoM-z14, offering new insight into star formation and galaxy growth in the early universe ...

Astronomers using two of NASA’s most powerful space telescopes have discovered a massive cluster of galaxies forming much earlier in the universe than scientists thought possible. The finding suggests ...

NASA's James Webb Space Telescope has revealed yet another marvel from deep in outer space. A galaxy named MoM-z14 has taken the title of most distant galaxy the telescope has captured. It is a ...

"There is a growing chasm between theory and observation related to the early universe, which presents compelling questions ...

The most powerful cosmic rays in the universe currently have no explanation. New research suggests that exotic, self-annihilating particles in our own galaxy may hold the answer. When you purchase ...

Webb discovered the incredibly distant galaxy JADES-GS-z13-1, observed at just 330 million years after the Big Bang. Researchers used the galaxy's brightness in different infrared filters to estimate ...

NASA has confirmed its sightings of the farthest known galaxy to date, providing an unprecedented look back into the early universe about 280 million years ...

Oxygen has been detected in the most distant galaxy ever discovered, surprised astronomers said Thursday, offering further evidence that stars in the early universe matured far quicker than had been ...
