Geomagnetic storm from a solar flare could disrupt radio communications and create a striking aurora
Space weather forecasters have issued a geomagnetic storm watch through Monday, saying an ouburst of plasma from a solar flare could interfere with radio transmissions on Earth. It could also make for great aurora viewing......»»
The cosmic neutrino background would tell us plenty about the universe, says researcher
Readers of Universe Today are probably already familiar with the concept of the cosmic microwave background (CMB). Its serendipitous discovery by a pair of radio astronomers at Bell Labs is the stuff of astronomical legend. Over the past decades, it.....»»
Astronomers propose a 50-meter submillimeter telescope
Some parts of the universe only reveal important details when observed in radio waves. That explains why we have ALMA, the Atacama Large Millimeter–submillimeter Array, a collection of 7-meter and 12-meter radio telescopes that work together as an.....»»

Before CarPlay, Apple previewed ‘iOS in the Car’ with a very different design
CarPlay has graduated from a niche upgrade option to a mainstream standard feature in new cars, replacing clunky radio user interfaces with a design very familiar for iPhone users. But before Apple set CarPlay loose in the wild, the world was shown a.....»»
Radio waves can tune up bacteria to become life-saving medicines
Scientists from Australia and the United States have found a new way to alter the DNA of bacterial cells—a process used to make many vital medicines including insulin—much more efficiently than standard industry techniques......»»
Researchers leverage machine learning to improve space weather predictions
There are three levels of severity for space storms: geomagnetic storms, solar radiation storms and radio blackouts. These storms produce different effects on Earth, including satellite, GPS, communications and electrical grid issues, as well as heal.....»»
Observations explore radio jet of a powerful quasar
European astronomers have conducted very long baseline interferometric (VLBI) observations of a radio jet structure in a powerful quasar known as PKS 2215+020. The collected VLBI data provide important insights into the properties of this jet, sugges.....»»
Newly spotted black hole has mass of 17 billion Suns, adding another daily
An accretion disk 7 light-years across powers an exceptionally bright galaxy. Enlarge (credit: ESO/M. Kornmesser) Quasars initially confused astronomers when they were discovered. First identified as sources of radio-fre.....»»
Astronomers are figuring out what causes incredibly bright flashes in space
Some of the oddest cosmic phenomena are short but powerful flashes called fast radio bursts. Now astronomers have observed one before and after it occurred,.....»»
Another clue into the true nature of fast radio bursts
Fast radio bursts (FRBs) are strange events. They can last only milliseconds, but during that time can outshine a galaxy. Some FRBs are repeaters, meaning that they can occur more than once from the same location, while others seem to occur just once.....»»
Apple Music launches new personalized ‘Love’ and ‘Heartbreak’ stations
