AUSTIN, Texas — An international team of astronomers led by Fritz Benedict and Barbara McArthur of The University of Texas at Austin has used Hubble Space Telescope to solve one of the biggest ...

The universe is unimaginably vast. Even the nearest stars are incredibly far away. Our galaxy is just one of billions. Traveling vast cosmic distances requires immense energy. Key takeaways sponsored ...

In its first year of full operations, the Euclid space telescope has quietly built one of the most ambitious maps of the ...

Researchers have discovered a potential 'cosmic glitch' in the universe's gravity, explaining its strange behavior on a cosmic scale. A group of researchers at the University of Waterloo and the ...

Scientists estimate that dark matter and dark energy together are some 95% of the gravitational material in the universe while the remaining 5% is baryonic matter, which is the “normal” matter ...

Imagine waking up one day to find out you live inside a vast, invisible bubble — a region of space so vast it stretches a billion light-years across, and yet so elusive it leaves no visible boundary.

The Roman telescope will track 100,000 cosmic explosions, revealing how the early universe expanded and offering new clues ...

Einstein's theory of general relativity is our best description of the universe at large scales, but a new observation that reports a "glitch" in gravity around ancient structures could force it to be ...

Velocity streamlines within the reconstructed volume, with colored envelopes associated with the prominent nearby basins of attraction. The map and streamlines have been cropped to the region covered ...

This illustration of the large GRB ring, and the inferred underlying large-scale structure, shows what might be responsible for the pattern we've observed. However, this may not be a true structure, ...

An illustrated timeline of the Universe's history. If the value of dark energy is small enough to admit the formation of the first stars, then a Universe containing the right ingredients for life is ...
