Astronomers have discovered the brightest and most distant "megamaser" to date. The cosmic energy beam is shooting toward ...

The universe hosts events so powerful that they dwarf anything humans can imagine. From magnetar flares and neutron star collisions to hypernovae and gamma-ray bursts, some cosmic explosions release ...

Cosmic voids are different. These vast expanses contain very little matter. In such places, the vacuum of space-time itself becomes the dominant component. If you were positioned at the center of a ...

Black holes that turn matter into energy could explain dark energy and answer two other cosmic questions. Now, the challenge ...

A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and ...

Asteroids with tiny moons may be quietly trading material across space. Images from NASA’s DART mission revealed faint ...

Some of the universe's most extreme explosions leave behind almost no trace. The original explosion is unseen, but our observations can capture the long-lived echo it leaves behind as the shock front ...

A newly detected X-ray transient may reveal the first direct evidence of an intermediate-mass black hole consuming a white dwarf. A newly observed cosmic outburst is giving astronomers a rare glimpse ...

The universe is a place of unimaginable beauty and wonder—shimmering galaxies that dance across the cosmic stage, nebulae ...

"The polarized light of the cosmic microwave background is sensitive to new physics that violates parity symmetry," the team ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...
