A New FRB Signal Has Buzzed Nearly 2,000 Times in Just Two Months, Raising a Mystery

We have detected a strange new signal from across the chasm of time and space. A repeating fast radio burst source detected last year was recorded spitting out a whopping 1,863 bursts over 82 hours, amid a total of 91 hours of observation. This hyperactive behavior has allowed scientists to characterize not just the galaxy that …

NASA gears up to deflect asteroid, in key test of planetary defense

A man sits at his workstation within the Mission Operations Center for the Double Asteroid Redirection Test (DART) spaceship, which is fast approaching its target. Bet the dinosaurs wish they’d thought of this. NASA on Monday will attempt a feat humanity has never before accomplished: deliberately smacking a spacecraft into an asteroid to slightly deflect …

Electricity Superconductivity Concept

Superconductor Breakthrough: Scientists Discover an Invisible Phenomenon

The discovery is a step towards much more accessible superconductivity. It may be possible to develop superconductors that operate at room temperature with further knowledge of the relationship between spin liquids and superconductivity, which would transform our daily lives. Superconductors offer enormous technical and economic promise for applications such as high-speed hovertrains, MRI machines, efficient …

Dinosaur Extinction Asteroid

What Really Killed Dinosaurs and Other Life on Earth? Maybe NOT an Asteroid Strike

While some scientists think that asteroid and comet strikes are the cause of mass extinction events on Earth, new research from Dartmouth points to volcanic eruptions as the key driver. Dartmouth-led research fortifies link between mega volcanoes and mass extinctions. What killed the dinosaurs 66 million years ago at the end of the Cretaceous Period? …

The First Object to Visit Us From Another Star System Could Be a Spaceship

You know scientists: They give the coolest possible explanation to the public and then act like nerds and release a paper years later saying something much more mundane. And so it is with the first object to enter our solar system from a different place. Dubbed “Oumuamua,” scientists are still arguing over what the mysterious …

Astronomers “Blown Away” by First Breathtaking Webb Space Telescope Images of Orion Nebula

The inner region of the Orion Nebula as seen by the James Webb Space Telescope’s NIRCam instrument. This is a composite image from several filters that represents emissions from ionized gas, molecular gas, hydrocarbons, dust, and scattered starlight. Most prominent is the Orion Bar, a wall of dense gas and dust that runs from the …
