Astronomers discover an unusual long-period radio transient

An international team of astronomers report the discovery of a long-period radio transient, which is unusually circularly polarized and showcases an accelerating spin period. The finding of the new transient, designated CHIME J1634+44, was detailed in a paper published July 7 on the pre-print server arXiv.

Scientists discover mysterious object that may be the oldest comet ever detected

Astronomers have just discovered what might be the oldest comet ever seen by humanity—an ancient visitor that predates our solar system by billions of years. This interstellar object, named 3I/ATLAS, was first spotted on July 1, 2025, by the ATLAS survey telescope in Chile. Astronomers now believe it could be more than seven billion years old, far older than our own solar system’s 4.5 billion years. An Unprecedented Cosmic Visitor Matthew Hopkin…

CHIME Telescope Uncovers Never-Before-Seen Radio Object With Accelerating Spin

An international team of astronomers has uncovered a new class of radio-emitting celestial object that could redefine what we know about long-period radio transients. In a study published on arXiv, the team describes CHIME J1634+44, a highly unusual source discovered through the CHIME/FRB Pulsar Survey. What sets this object apart is not only its unusually long spin period, but also its rare circular polarization and signs of accelerating rotati…
