Most powerful cosmic radio ring yet found by citizen scientists
Sunday, 05 October 2025 22:53
The most distant and powerful odd radio circle (ORC) ever detected has been discovered by astronomers working with citizen scientists.
ORCs are giant, faint rings of radio emission surrounding galaxies, visible only in radio wavelengths and composed of relativistic, magnetised plasma. First identified in 2019, only a few confirmed examples exist, most spanning 10-20 times the diameter of t Young rogue planet displays record-breaking 'growth spurt'

A young rogue planet about 620 light-years away from Earth has experienced a record-breaking "growth spurt," hoovering up some six billion tons of gas and dust each second over a couple of months.
A team of international researchers have explored changes in the planet's growth and immediate surroundings. The observations provide insight into how rogue planets - free-floating planetary-mass Detection of phosphine in a brown dwarf atmosphere raises more questions

Phosphorus is one of six key elements necessary for life on Earth. When combined with hydrogen, phosphorus forms the molecule phosphine (PH3), an explosive, highly toxic gas. Found in the atmospheres of the gas giant planets Jupiter and Saturn, phosphine has long been recognized as a possible biosignature for anaerobic life, as there are few natural sources of this gas in the atmospheres of terr Cosmic constants may explain away dark matter and dark energy

For decades, astronomers have assumed that dark matter and dark energy dominate the cosmos. Now, new research from the University of Ottawa challenges that foundation, proposing that these unseen components may be illusions caused by the gradual weakening of nature's fundamental forces as the universe ages.

Astronomers have discovered the most distant and powerful odd radio circle (ORC) ever observed, revealing a rare cosmic structure nearly halfway across the universe. The newly identified source, RAD J131346.9+500320, lies at a redshift of about 0.94 - when the universe was roughly half its present age.
These enormous, faint rings of magnetised plasma emit only in the radio band and typical T-Satellite powers smartphone apps beyond cell coverage
