Researchers have long believed that Mars once had a thick, carbon dioxide-rich atmosphere and liquid water on the planet’s surface. That carbon dioxide and

As the global pursuit for sustainable energy solutions intensifies, water splitting remains a promising avenue for producing clean hydrogen fuels. But the process of splitting water into hydrogen and oxygen is inherently inefficient—requiring significantly more energy than theoretically predicted.

“Phantom” dark energy existed long ago, observations suggest

New data further challenge the best scientific theory of the history and the structure of the universe. But a separate recent result reinforces it.

A new study published in PLOS Genetics has identified an extreme mutational hotspot within the genome of Pseudomonas fluorescens, providing unprecedented insight into the relationship between gene regulation and mutation rates. The findings could have broad implications for understanding bacterial e...

Instantly turning a material from opaque to transparent, or from a conductor to an insulator, is no longer the stuff of science fiction. For several years now, scientists have been using lasers to control the properties of matter at extremely fast rates: during one optical cycle of a light wave. But...

This image captured by Firefly Aerospace’s Blue Ghost lander on March 3 shows sunrise on the lunar surface.

It’s neither fast nor food, but a spectacular object called HH 30 looks appetizing for astronomers in a new image from the James Webb Space Telescope

A Milky Way collision with a supermassive black hole might be closer than we thought.

It only took less than 10 minutes.

"Black holes really do sit at the frontier of human understanding."

Scientists are using revolutionary 3D galaxy maps and advanced computational techniques to uncover the hidden structures of dark matter, the invisible substance shaping the universe. Through a method called field-level inference (FLI), researchers are reconstructing the intricate web of dark matter ...

When the Eaton Fire erupted, the Mountain View Cemetery and Mortuary in Altadena faced a rare struggle: racing to save thousands of loved ones who already passed. Heroic efforts saved the historic cemetery from the flames.

"Our measurements imply that the supermassive black hole mass is 10% of the stellar mass in the galaxies we studied."

Astronomers have taken a crucial step in showing that the most massive black holes in the universe can create their own meals. Data from NASA’s Chandra X-ray

This composite image of Mars passing behind the Moon was captured from the Observatorio del Teide in Tenerife, Spain, on Jan. 14., 2025. The Moon's…

"The launch of a black hole jet has never been observed before in real-time."

Your navigation system just got a critical update, one that happens periodically because Earth’s magnetic north pole keeps moving. Here’s what to know.
