Chalk up another victory for “Conan the Bacterium”—a rugged germ that fresh research suggests could conquer the solar system.

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...

Chalk up another victory for “Conan the Bacterium”—a rugged germ that fresh research suggests could conquer the solar system.

Scientific advancements have made it possible to peek into a faraway galaxy that has big implications.

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

The liquid outer core is surrounded by the thick layer called the mantle. It’s mostly solid rock, not melted like lava. Over time, changes in heat and pressure make the solid rock slowly flow. It’s ...

Explore how Earth would appear without life. Studies from Universe Today and Cornell University reveal atmospheric signals, surface conditions, and implications for exoplanet observations.

A rare gravitationally lensed supernova called SN 2025wny appears in five separate images due to the gravity of two ...

Compared to previous theories, the current research emphasizes the complexity of the biological and chemical processes that brought about life.

At first, the universe was like a hot stew. Instead of carrots and potatoes, it had particles. As the soupy universe cooled, ...
