Astrophysicists don’t know if direct-collapse black holes are real. They were hypothesized to explain how the Universe could contain supermassive black holes (SMBH) so early. They don’t require a stellar progenitor, nor do they require hierarchical merging. Instead, they collapse due to instability in a gas cloud, much like stars do. Recently, astronomers working with images from the COSMOS-Web survey, …

Robots that Grow by Consuming Other Robots – YouTube Watch On Scientists have created a prototype robot that can grow, heal and improve itself by integrating material from its environment or by “consuming” other robots. It’s a big step forward in developing robot autonomy, the researchers say. The researchers coined the term “robot metabolism” to describe the process that enables …

An unusual fossil brain suggests that the ancestors of spiders and other arachnids may have once scuttled around the sea, rather than on land as was long thought, a new study finds. The fossil shows that certain features of the brain of a now-extinct animal known as Mollisonia symmetrica are arranged backward compared with those of most modern arthropods, a …

The Juno spacecraft was launched towards Jupiter in August of 2011 as part of the New Frontiers series of spacecraft, on what would originally have been a 7-year mission, including a nearly 5 year cruise to the planet. After a mission extension, it’s currently orbiting Jupiter, allowing for many more years of scientific data to be gathered using its instruments. …

When NASA’s upcoming Dragonfly probe skims the lakes of Saturn‘s moon Titan, it may encounter a froth akin to Earth’s first signs of life, a new study suggests. Titan is strikingly similar to Earth in some respects. Like the planet we call home, its surface is covered with large lakes and seas of liquid. And, much like the water cycle …

Two of Arizona’s most famous landmarks may be linked by cosmic violence: the asteroid that gouged out Meteor Crater may have also caused the formation of an ancient lake in the Grand Canyon. This surprising connection between Arizona’s world-renowned geological features stretches back 56,000 years, to when a 300,000 ton nickel-iron asteroid slammed into the Colorado Plateau with the force …

During the midday Friday prayer hours on March 28, 2025, a magnitude 7.7 earthquake struck central Myanmar along the Sagaing Fault. With an epicenter close to Mandalay, the country’s second-largest city, it was the most powerful earthquake to strike Myanmar in more than a century and the second deadliest in its modern history. The cause was a strike-slip fault, in …

NASA’s Juno spacecraft, which launched in 2011 to investigate Jupiter’s origin and evolution, travels through the solar system’s most intense planetary radiation fields. When the spacecraft’s JunoCam—a color, visible-light camera—began to suffer the consequences in December 2023, the mission team back on Earth had to think of a remote fix before they lost their chance to photograph the Jovian moon, …
