It may not have been a massive fireball, but SpaceX now has more work to do before it can kick off this next-generation version of Starship.

The quiet arrival offers another indication that the sun is moving into the declining phase of its 11-year cycle.

Scientists are intrigued by how gold nuggets form, often tucked in quartz veins. The process seems to involve earthquakes and electricity.

Thousands of earthquakes were caused by magma "pumping through" Earth's crust for three months, they say.

Over the course of billions of years, the Universe has steadily been evolving.

It all comes down to the fuel.

When ultraviolet light hits ice—whether in Earth's polar regions or on distant planets—it triggers a cascade of chemical reactions that have puzzled scientists for decades.

NASA named astronaut Scott Tingle as chief of the Astronaut Office at the agency’s Johnson Space Center in Houston, effective Nov. 10. A decorated spaceflight

In 2026, a first-of-its-kind spacecraft—launched on a rocket dropped out of a plane—will attempt to save NASA’s Swift observatory from a fiery demise. Yes, really.

"This challenges our understanding of black hole and galaxy formation in the early universe."

A new framework argues that human language did not arise from a single evolutionary leap but from the convergence of many biological abilities and cultural processes.

The inside of giant planets can reach pressures more than one million times the Earth's atmosphere. As a result of that intense pressure, materials can adopt unexpected structures and properties. Understanding matter in this regime requires experiments that p…

NASA astronaut Chris Williams will launch aboard the Roscosmos Soyuz MS-28 spacecraft to the International Space Station on Thursday, Nov. 27, accompanied by

Scientists find the DNA of a 300,000-year-old horse in Schöningen, driven to extinction by hunting, next to a wooden spear that killed it.

NASA is unveiling close-up pictures of the interstellar comet that's making a quick one-and-done tour of our solar system.

About 4.5 billion years ago, the most momentous event in the history of Earth occurred: a huge celestial body called Theia collided with the young Earth. How the collision unfolded and what exactly happened afterward has not been conclusively clarified. What …

A large radio galaxy study finds our solar system moves faster than theory predicts, raising new questions about how matter spreads.

In a new study published in Nature Physics, researchers have demonstrated that quantum light, particularly bright squeezed vacuum (BSV), can drive strong-field photoemission at metal needle tips.

Simulating a billion years using previous best-resolution simulations would take almost 36 years of real computing time.

Scientists have uncovered an unexpected function for a crucial protein involved in cell division. Reported in two consecutive publications, the finding challenges long-accepted models and standard descriptions found in biology textbooks. Researchers at the Ru…

If confirmed, the structure may be primordial.

Are Uranus And Neptune Really Ice Giants? has 10 comments. Commenter peacey_bon-bon wrote: "cool!"

In a discovery shaped by more than a decade of steady, incremental effort rather than a dramatic breakthrough, scientists from the National University of Singapore (NUS) and their collaborators demonstrated that great ideas flourish when paired with patience.

Uranus will appear opposite the sun in Earth's sky on Nov. 21.

It might seem gross, but these materials are treasure troves for research.
