Space: Fast Radio Burst [FRB] Reaches Earth After Travelling 10 Billion Years! (23.9.2025)

Why cosmic noon matters

The burst came from a time nicknamed “cosmic noon,” when the universe was forming stars at its fastest rate.

Astronomers see a peak in the cosmic star formation history about 10 to 11 billion years ago, and this event sits in that era.

Finding an FRB there matters for more than a date on a timeline. It shows that whatever powers FRBs was active when young galaxies were busy building their stars.

“This discovery doubles the redshift reach of localized FRBs. Our observations establish FRB activity during the peak of cosmic star formation” wrote Caleb.

Magnetic Pulse - Chirp - 2025

China: Joint Research Team – Unexpected “Chirping Chorus” Detected from Outer Space! (23.1.2025)

According to the research team, electromagnetic bursts play a crucial role in the formation of the Earth’s radiation belts, pulsating auroras, and the precipitation of particles into its atmosphere. Traditional views hold that chorus waves are formed in the magnetic field of a dipole of near-Earth space, where the magnetic field is similar to a large bar magnet.

The newly-found chorus waves were detected in a region where Earth’s magnetic field is stretched out, which scientists didn’t expect. They lasted about 0.1 second with a frequency of nearly 100 hertz per second, which are similar to the waves detected in near-Earth space. That raises fresh questions about how these chirping waves form.
