A “ghost particle” discovered by a detector in the Mediterranean carried 30 times more energy than any neutrino observed to ...

Hubble observes in primarily optical light—the wavelength range human eyes can see whereas JWST ... 400 identified supernova remnants in our galaxy. Getting a larger sample will help researchers ...

The idea of cosmic threats to Earth almost sounds like the stuff of fiction. But while alien invasions may be far fetched, these threats are perfectly real.

Take, for instance, one such fast radio burst astronomers recently tracked to the distant outskirts of a long-dead galaxy. Based on what scientists thought they knew about fast radio bursts, referred ...

A blast of radio waves from the outskirts of an ancient galaxy challenges theories about what creates such bursts.

The powerful burst was also traced to an unprecedented 130,000 light-years from its associated galaxy’s center, where few other stars exist. Fast radio bursts, strong pulses of energy detected ...

For the first time, astronomers have traced a fast radio burst (FRB) to the outskirts of an ancient, dead, elliptical galaxy -- an unprecedented home for a phenomenon previously associated with ...

Astronomers studying FCC 224, an ultra-diffuse galaxy, have discovered luminous, overmassive globular clusters, providing key ...

The research appears in the journal Astrophysical Journal Letters, in two papers: “A repeating fast radio burst source in the outskirts of a quiescent galaxy” and “The massive and quiescent ...
