Neutron stars: a mysterious object emits radio waves every 18 minutes

Something extraordinarily bright in space is pulsating much slower than most similar cosmic objects, and it may be a strange kind of neutron star we’ve never seen before Space out January 26, 2022 By Lea Crane A view of the Milky Way from the Murchison Widefield Array. The star-shaped icon indicates the position of the […]

Mysterious radio waves from the heart of the Milky Way confuse astronomers

Astronomers have detected mysterious radio waves originating from the center of the Milky Way, but so far have no idea what causes them, according to a new study published in the Astrophysical Journal on Tuesday. A team of scientists from around the world discovered the object using the CSIRO radio telescope in Western Australia. Ziteng […]

Scientists baffled by radio waves from the center of the Milky Way

Astrophysicists are baffled by a strange energy signal recently detected in the heart of the Milky Way galaxy, CNN reports. The radio signal, picked up by a telescope in Australia, is unlike any phenomenon scientists have seen before and could suggest a previously unknown stellar object, according to a new study. Upon its initial discovery, […]

Space: mysterious radio waves arrive from the center of the galaxy

Through Lea Crane Illustration of radio waves coming from the galactic center Sebastien zentilomo Strange radio signals are coming from the center of the galaxy and we don’t know what is emitting them. They seemingly turn on and off at random, and their source must be unlike anything we’ve seen before. The source of this […]

Variable signal aligned at the heart of the Milky Way galaxy appeals to scientists – sciencedaily

Astronomers have discovered unusual signals coming from the direction of the center of the Milky Way. The radio waves do not correspond to any currently understood model of a variable radio source and could suggest a new class of stellar objects. “The strangest property of this new signal is that it has a very high […]

Never-before-seen radio waves detected from nearby stars and distant galaxies

Scientists measured thousands of nearby stars and distant galaxies that had never before been identified at radio wavelengths, while studying a galactic body near ours Milky Way galaxy – the Large Magellanic Cloud. Led by Keele University PhD student Clara M. Pennock and astrophysics reader Dr Jacco van Loon, the international team of researchers used […]

Mysterious fast radio bursts include lower frequency radio waves than previously detected

A burst from the periodically active repeating fast radio burst source 20180916B arrives at the LOFAR telescope. High frequency radio waves (purple) arrive earlier than low frequency radio waves (red). The inset shows an optical image of the host galaxy of the fast radio burst source and the position of the source within the host […]

Fast radio bursts include lower frequency radio waves than previously detected – sciencedaily

Ever since rapid radio bursts (FRBs) were first discovered over a decade ago, scientists have wondered what could generate these intense flashes of radio waves coming from outside our galaxy. In a gradual process of elimination, the field of possible explanations has narrowed as more information is gathered about FRBs – their lifespan, the frequencies […]

Astronomers detect a regular rhythm of radio waves, of unknown origin | MIT News

A team of astronomers, including researchers from MIT, has picked up a curious, repetitive rhythm of fast radio bursts emanating from an unknown source outside our galaxy, 500 million light-years away. Fast radio bursts, or FRBs, are short, intense flashes of radio waves thought to be the product of small, distant, extremely dense objects, although […]

Pattern in radio waves: first contact, right?

Periodic radio waves hitting Earth from a nearby galaxy are unlikely to come from extraterrestrials, but the possibility cannot be ruled out. The CHIME radio telescope in Canada has been recording Fast Radio Burst (FRB) 180916.J0158+65 since 2018. (Inset) Image of the host galaxy with the region containing the FRB source outlined in green (Photographs: […]

What are radio waves? | Live Science

Radio waves are a type of electromagnetic radiation best known for its use in communication technologies, such as television, cell phones, and radios. These devices receive radio waves and convert them into mechanical vibrations in the speaker to create sound waves. The radio frequency spectrum is a relatively small part of the electromagnetic (EM) spectrum. […]

How to explore the hidden world of radio waves all around you

One day this fall, in an old factory in Brooklyn’s Bushwick neighborhood, a row of ’90s pagers chirped and buzzed. Next to their dimly lit screens was a receipt printer – like the one you might find in a cash register – spitting out long spools of paper. As my eyes scanned the prints, I […]
