Hints of intriguing diversity seen in super-energetic ‘fast radio bursts’

by

The story of sneaky fast radio bursts (FRBs) may be more complicated than we imagined. It’s tough to figure out the origin stories of FRBs because they’re so brief, so bright and appear to come from numerous regions in the sky. Most of these powerful cosmic blasts seem to occur in young galaxies, although that’s … Read more

Mysterious repeating fast radio burst from space looks strangely familiar, scientists realize

by

Scientists got a strange sense of déjà vu when they took a close look at a mysterious series of bright flashes in a galaxy just 12 million light-years away. The flashes, known as a repeating fast radio burst (FRB), appear surprisingly similar to flashes found in the Crab Nebula. The Crab Nebula is a famous … Read more

Mysterious Repeating Fast Radio Burst Traced to Very Unexpected Location

by

A recently discovered repeating fast radio burst (FRB) named FRB 20200120E is deepening the mystery of these already deeply mysterious space signals. Astronomers have tracked its location to a galaxy 11.7 million light-years away, which makes it the closest known extragalactic fast radio burst, 40 times closer than the next-closest extragalactic signal.   But it … Read more

The Main Reason People Avoid Fast Food May Not Be Unhealthiness, Study Finds

by

On any given day, about one in three adult Americans eats fast food. There are some problems associated with this. Lots of research suggests fast food isn’t good for you, and it’s been linked to the obesity epidemic affecting millions in the US, among a host of other issues related to health.   But according … Read more

Glacier Lakes Make Permanent Ice Disappear Over Twice as Fast, Study Reveals

by

Glaciers are retreating faster globally due to climate change but they melt more quickly when they flow into a lake than when they end on land, with consequences for water supplies, a new study found on Thursday.   The Swiss-funded study is the first large-scale, detailed analysis of the phenomenon in mountain glaciers and could … Read more

The mystery deepens: Ghostly neutrinos and fast radio bursts don’t come from the same place

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of “Ask a Spaceman” and “Space Radio,” and author of “How to Die in Space.” Sutter contributed this article to Space.com’s Expert Voices: Op-Ed & Insights. The universe is a pretty busy place, with stars blowing up, black holes consuming … Read more

How fast is Earth moving?

by

As an Earthling, it’s easy to believe that we’re standing still. After all, we don’t feel like we’re hurtling through space. Yet we are.  So how fast exactly is Earth moving around the sun?  Some of the earliest astronomers in recorded history proposed that we live in a geocentric universe in which Earth lies at … Read more

How Fast Does Light Travel? | The Speed of Light

by

Light traveling through a vacuum moves at exactly 299,792,458 meters (983,571,056 feet) per second. That’s about 186,282 miles per second — a universal constant known in equations and in shorthand as “c,” or the speed of light.  According to physicist Albert Einstein‘s theory of special relativity, on which much of modern physics is based, nothing … Read more

Gravitational waves play with fast spinning stars, study suggests

by

Scientists observed changes in the signals coming from rapidly-spinning stars called millisecond pulsars that might point to the existence of subtle space-time ripples vibrating throughout the entire universe. Millisecond pulsars are stellar remnants that spin hundreds of times per second, producing precise radio pulses that can act as a cosmic metronome. Scientists think that ripples … Read more
