Starlinks are easily detected by radio telescopes
Radio astronomy and satellite communication have a long common history. Advances made in one field have benefitted the other, and our modern era of spacecraft and mobile internet is a product of this partnership. But there are times when the goals of.....»»
Heat Waves in the Ground Are Getting More Extreme—and Perilous
The atmosphere is rapidly warming, but the soil is also prone to heat waves. Scientists are racing to understand the consequences......»»
Large-scale bent radio jet detected in galaxy cluster Abell 514
Astronomers have conducted deep low-frequency radio observations of the galaxy cluster Abell 514, using the upgraded Giant Metrewave Radio Telescope (uGMRT). In their results, they detected a large-scale bent radio jet in this cluster. The finding is.....»»
Vega"s PRETTY CubeSat: Unlocking satnav for Earth data
Our planet is being continuously bathed in radio signals from satnav satellites—which are useful for much more than just navigation. Dedicated space missions acquire these signal reflections to amass valuable environmental information. The shoebox-.....»»
How Arctic landscapes and Canadian cityscapes share a similar pattern
The year 2023 has been one of extremes, from heat waves that baked millions across the globe and made the summer the world's hottest on record to the fires that forced tens of thousands to evacuate across Western Canada. From the feel of surprising w.....»»
Study shows defects spreading through diamond faster than the speed of sound
Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do......»»

As heat waves warm the Pacific Ocean, effects on marine life remain murky
Scientists are pretty good at recognizing marine heat waves. A global network of thousands of oceanic buoys and orbiting satellites allow them to see, in real time, ocean surface temperatures, changing currents and storm systems as they develop, move.....»»
The world"s largest radio telescope has scanned Barnard"s star for extraterrestrial signals
Barnard's Star is a small red dwarf just six light-years from Earth. Despite its proximity, it was only noticed in 1916 when E. E. Barnard found it had a particularly high proper motion. It had appeared in photographic plates taken by Harvard Observa.....»»

Listening to the radio on the far side of the moon
There are unexplored regions of the universe—and there are also unexplored times. In fact, there's a nearly 400-million-year gap in our universe's history that we've never seen: a time before stars known as the Dark Ages. To investigate that era, r.....»»
Tivoli Audio reimagines its SongBook as two retro-style boomboxes
The Tivoli Audio SongBook is back, but it looks nothing like the original clock radio from 2004. The SongBook and SongBook Max are powerful Bluetooth portables......»»
Single sideband modulation technique can relax the bandwidth restriction
As an ultra-wideband microwave signal, amplitude shift keying (ASK) can be used in many applications, such as electronic warfare, wireless communications and modern radar systems. Initially, ASK microwave signals are generated based on radio frequenc.....»»
