Scientists develop high-power optic fiber laser to power nano satellites
The use of lasers in space is a reality. Even though radio waves have been the backbone of space communications for ages, the demand to convey more data, in a faster way, made these lighter, more flexible, and more secure infrared rays (invisible to.....»»
Astronomers produce most sensitive radio image ever of ancient star cluster
A global team of astronomers have created the most sensitive radio image ever of a globular cluster, an ancient ball of tightly packed stars......»»
Gravitational waves could show us the first minute of the universe
Astronomers routinely explore the universe using different wavelengths of the electromagnetic spectrum from the familiar visible light to radio waves and infrared to gamma rays. There is a problem with studying the universe through the electromagneti.....»»

What is Auracast? The Bluetooth broadcast standard fully explained
With Auracast, your Bluetooth headphones are going to be a lot more useful, and your phone can act as a personal radio station. Here's what you need to know......»»
New paper explores four nearby fast radio burst sources
Fleeting blasts of energy from space, known as fast radio bursts (FRBs), are a cosmic enigma. A Canadian-led international team of researchers has published new findings suggesting that supernovae are the predominant contributors to forming sources t.....»»
Astronomers think they finally know origin of enormous “cosmic smoke rings“
Massive stars burn out quickly. When they die, they expel their gas as outflowing winds. Enlarge / Odd radio circles are large enough to contain galaxies in their centers and reach hundreds of thousands of light years across. (c.....»»
"Blob-like" home of farthest-known fast radio burst is collection of seven galaxies, researchers find
In summer 2022, astronomers detected the most powerful fast radio burst (FRB) ever observed. And coming from a location that dates halfway back to the Big Bang, it also was the farthest known FRB spotted to date......»»
Space oddity: Uncovering the origin of the universe"s rare radio circles
It's not every day astronomers say, "What is that?" After all, most observed astronomical phenomena are known: stars, planets, black holes and galaxies. But in 2019 the newly completed ASKAP (Australian Square Kilometer Array Pathfinder) telescope pi.....»»
First release of the largest extragalactic HI catalog
The FAST All Sky HI survey (FASHI) was designed to cover the entire sky observable by the Five-hundred-meter Aperture Spherical radio Telescope (FAST), spanning approximately 22,000 square degrees of declination between -14 deg and +66 deg, and in th.....»»
FAST detects three new pulsars in an old globular cluster
Using China's Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have discovered three new pulsars in an old Galactic globular cluster known as Messier 15. Two of them turned out to be long-period pulsars, while the remaining o.....»»
History and contents of the universe can be determined using radio telescopes on the moon, researchers say
A study from Tel Aviv University has predicted for the first time the groundbreaking results that can be obtained from a lunar-based detection of radio waves. The study's findings show that the measured radio signals can be used for a novel test of t.....»»
Second radio relic discovered in the galaxy cluster Abell 2108
Astronomers from India and Taiwan have used the upgraded Giant Metrewave Radio Telescope (uGMRT) to perform radio observations of a galaxy cluster known as Abell 2108. As a result, they detected a second radio relic, which is much larger and differs.....»»
Breakthrough Listen scans entire galaxies for signals from extremely advanced civilizations
In 1960, Dr. Frank Drake led the first Search for Extraterrestrial Intelligence (SETI) experiment at the National Radio Astronomy Observatory in Green Bank, West Virginia. In the more than sixty years that have since passed, astronomers have conducte.....»»
