Not so long ago, astronomers mapped a galaxy far, far away using radio waves and found it has a strikingly familiar shape. In the process, they discovered the object, called TXS 0128+554, experienced two powerful bouts of activity in the last century.

Is it possible to hear meteors?
Can you hear a meteor as it streaks overhead? Some people have reported hearing meteors with a sizzling sound like bacon frying. Scientists now say you can, and explain how it happens. Source: https://earthsky.org/space/whoosh-can-you-hear-a-meteor-streak-past…
Plant protein responds to radio waves by making seedlings grow faster
A type of protein found in plants and animals called a cryptochrome seems to respond to radio waves, changing how genes in thale cress seedlings are expressed. The find could have applications in farming and medicine Source: https://www.newscientist.com/article/2251835-plant-protein-responds-to-radio-waves-by-making-seedlings-grow-faster/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
‘5G Just Got Weird’
SuperKendall (Slashdot reader #25,149) shared this review of the recent 5G standards codified by the 3rd Generation Partnership Project (3GPP) in Release 16 (finalized on July 3). “5G just got weird,” writes IEEE Spectrum: 4G and other earlier generations of cellular focused on just that: cellular. But when 3GPP members started gathering to hammer out what 5G could be, there was…
Circles in space made of radio waves are like nothing we’ve ever seen
Astronomers have discovered four circles of radio waves in space, but have no explanation for their origin. We don’t even know how big or far away they are Source: https://www.newscientist.com/article/2247978-circles-in-space-made-of-radio-waves-are-like-nothing-weve-ever-seen/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Saturn’s large moon Titan is drifting away 100 times faster than anyone knew
Saturn’s largest moon Titan is drifting away from the planet 100 times faster than previously thought, according to a new study from researchers in the U.S., France and Italy. Source: https://earthsky.org/space/saturn-moon-titan-drifting-away-100-faster…
Astronomers detect regular rhythm of radio waves, with origins unknown
A team of astronomers, including researchers at MIT, has picked up on a curious, repeating rhythm of fast radio bursts emanating from an unknown source outside our galaxy, 500 million light years away. Source: https://phys.org/news/2020-06-astronomers-regular-rhythm-radio-unknown.html…
Has mystery of universe’s missing matter been solved?
Cosmologists have only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, these researchers say they’ve just found the rest.

Mysterious Radio Bursts Reveal Missing Matter in Cosmos
sciencehabit writes: Roughly half of the “normal” matter in the universe — the stuff that makes up stars, planets, and even us — exists as mere wisps of material floating in intergalactic space, according to cosmologists. But astronomers had no good way to confirm that, until now. A new study has used fast radio bursts (FRBs) — powerful millisecondslong pulses of…
Cell-Tower Attacks By Idiots Who Claim 5G Spreads COVID-19 Reportedly Hit US
An anonymous reader quotes a report from Ars Technica: The Department of Homeland Security is reportedly issuing alerts to wireless telecom providers and law enforcement agencies about potential attacks on cell towers and telecommunications workers by 5G/coronavirus conspiracy theorists. The DHS warned that there have already been “arson and physical attacks against cell towers in several U.S. states.” The preposterous claim…
