A New Census of Dwarf Galaxies Shows More Massive Black Holes than Previously Thought
A new census of more than 8,000 galaxies finds active black holes rising in frequency with galaxy mass, jumping sharply in galaxies similar in mass to the Milky Way.
NASA’s Artemis II mission to the moon is inching toward the launch pad
NASA rolled out the fully stacked Artemis II rocket and Orion capsule on Saturday, embarking on a four-mile journey to the launch pad
This gene may determine if dogs have long, floppy ears or short, study ones
Scientists are just beginning to understand the signals that determine the length of dogs’ ears
World models could unlock the next revolution in artificial intelligence
Why today’s AI systems struggle with consistency and how emerging world models aim to give machines a steady grasp of space and time

Analysis of Chang'e-6 Samples Addresses Mysteries About the Far Side of the Moon.
Our nearest neighbor, the Moon, is still something of a mystery to us. For decades, scientists have wondered why it appears so lopsided, with dark volcanic plains on the near side (the side we see) and rugged, cratered mountains and a thicker crust on the far side. Now we might be closer to knowing why.
A Simulated Asteroid Impact Reveals the Strength of Iron-Rich Rocks
Physicists at the University of Oxford have contributed to a new study which has found that iron-rich asteroids can tolerate far more energy than previously thought without breaking apart - a breakthrough with direct implications for planetary defence strategies.
Exploring Where Planets Form With The Hubble Space Telescope
This collection of new images taken by NASA’s Hubble Space Telescope showcases protoplanetary disks, the swirling masses of gas and dust that surround forming stars, in both visible and infrared wavelengths. Through observations of young stellar objects like these, Hubble helps scientists better understand how stars form. These visible-light images depict dark, planet-forming dust disks […]
RFK, Jr., shifts focus to questioning whether cell phones are safe. Here’s what the science says
The possible health effects of radiofrequency waves emitted by cell phones has been a subject of debate for decades
It’s so cold in Florida that iguanas might rain from the skies
Florida’s iguanas are an introduced species, and they aren’t used to the chilly temperatures the state is currently experiencing
NASA’s historic Artemis II moon mission is almost ready to launch
On Friday NASA laid out the time line for Artemis II, humanity’s first crewed mission to the moon in more than 50 years
Why Mars is Actively Manufacturing Poison
Chemistry on other worlds varies widely from that on Earth. Much of Earth’s chemistry is driven by well-understood processes, which typically involve water and heat in some form. Mars lacks both of those features, which makes how some of its chemicals formed a point of ongoing debate in the scientific community. A new paper led by Alian Wang and Neil Sturchio of Washington University of St. Louis and the University of Delaware, respectively, and published recently in Earth and Planetary Science Letters offers a new framework for understanding chemical reaction processes on Mars. Despite the differences, Earthlings will still be familiar with the driving force behind Martian chemistry - electricity.
Protostars Carve Out Homes In The Orion Molecular Cloud
Young protostars populate the cloudy regions in the Orion Molecular Cloud complex in these images from the Hubble Space Telescope. Three of the telescope's new images are part of a scientific effort to understand the gaseous, dusty envelopes around protostars. Scientists know that these young stars have powerful stellar winds and jets that carve caverns and bubbles out of the surrounding gas, but they have unanswered questions about that process.
