Mysterious Intergalactic Radio Bursts Come From a Truly Strange Place

First detected in 2002, Fast Radio Bursts (FRBs) are quick, high-energy pulses originating from galaxies billions of light years away. Scientists still don’t know the true nature of these bursts or what’s causing them, but new observations of the only known repeating FRBs are providing details about the extreme environments in which these pulses are born.

2017’s Best Space Explosions

Astronomers spend their days looking at the sky. Maybe some crazy complex new telescope is helping, or some form of AI is teasing the complexities out of vast piles of data. It’s still just the sky. The sky isn’t immutable, though. Some of the most interesting science happens when brief blips pass into and out of existence. These dots send their light in the form of radio waves, microwaves, visible light and gamma rays into measuring apparatuses and tell us something new about the universe. They might even send space itself rippling with gravitational waves. Read More >>

Observatories Across the World Announce Groundbreaking New Gravitational Wave Discovery

Vicky Kalogera, a Northwestern University physicist, took her week of much-needed vacation in Utah this past August. She promised her family she’d stay off of email for a week. It wasn’t a real promise, of course, but she was going to try. She’d arranged the perfect day for August 17. Her husband was going to take the kids hiking in Arches National Park while she’d spend the whole day at the spa. Right as she left her room, she just had to give her email a peep. The deluge brought the news: Telescopes and detectors across the world were making a monumental observation. Read More >>

All the Gold on Earth Comes From Massive Space Explosions

Previously, astronomers had been under the impression that the heavy elements — gold, platinum, lead, uranium, etc. — came from supernova explosions. But now, scientists have announced a new theory for these highly valuable elements, this one involving two ultra-dense neutron stars and one spectacularly violent, grossly expensive collision.
