NASA’s Solar Dynamics Observatory (SDO) captured a solar flare and a coronal mass ejection (CME) on video on June 18. “The SDO has been studying the Sun since 2010 and captured this flare at multiple wavelengths, allowing it to show the ultraviolet light of the massive flare,” according to Mirror Online. The solar flare, which has been named “Spit of Satan,” lasted for four … [Read more...]
Astronomers Unveil View of Galaxy’s Electromagnetic Loop
This week at the National Astronomy Meeting (NAM 2015) in Wales, scientists working with the Planck Satellite, including Mike Peel and Paddy Leahy, revealed a new polarization map of the Milky Way in microwaves. This particular view of the electromagnetic loop discovered more than half of a century ago, has never been seen before. “It’s a full sky map showing synchrotron loops … [Read more...]
New Radio Telescope Detects Galaxy From 5 Billion Light Years Away
A new radio telescope in Western Australia, known as Australian Square Kilometre Array Pathfinder (ASKAP), has discovered PKS B1740-517 – a galaxy located more than 5 billion light years away. Six of the 36 dishes on the radio telescope captured signals emitted from PKS B1740-517. This discovery demonstrates that ASKAP can detect galaxies and signals that other telescopes … [Read more...]
Product’s Expanded Features Reveal Hidden Interference
Narda Safety Test Solutions has expanded the features of its Interference and Direction Analyzer (IDA), which will clarify and improve wireless signals. The IDA “Spectrograms with a time resolution of as fine as 1 μs now allow insights into signal structures that were otherwise only possible with large scale lab equipment. This means that interference and hidden transmitters … [Read more...]
‘Pregnant Women’ Wi-Fi Router Setting Causes Debate in China
Two Chinese tech firms, Qihoo 360 and Xiaomi, have quarreled over a wireless router with a unique setting for pregnant women. The two firms are intense rivals and have both recently released new products. Qihoo 360 released the wireless router that is currently at the center of controversy. The router has three settings: wall penetration, balance and pregnant women. The … [Read more...]
Energy-efficient Electric Car: No AM Radio Due to Possible EMI
The BMW i3 Electric Car was the most energy-efficient car sold in the U.S. this year, according to Green Car Reports. However, consumers noticed the car does not offer AM Radio. “AM is not offered due to negative performance influences of the electromagnetic interference of the electric drivetrain. Electric motors cause interference on AM which is why BMW decided to remove … [Read more...]
Saharan Ants Control Electromagnetic Waves to Stay Cool
A joint project conducted by Columbia University, The University of Washington and the University of Zürich indicates how Saharan Silver Ants stay cool in one of the hottest climates in the world. The team’s research paper titled ‘Saharan Silver Ants Keep Cool by Combining Enhanced Optical Reflection and Radiative Heat Dissipation’ was recently published in Science … [Read more...]
Defense Contractor to Produce Electromagnetic Aircraft Launch System
General Atomics, a defense contractor in San Diego, Calif., announced it will produce the Electromagnetic Aircraft Launch System (EMALS) and Advanced Arresting Gear (AAG) for the John F. Kennedy aircraft carrier under a contract from the U.S. Navy. The EMALS system uses bursts of electromagnetic energy to launch planes and jets into the air. It takes up less space on ships, … [Read more...]
EMI from Smartphones May Affect Cardiac Devices
Dr. Carsten Lennerz, cardiology resident in Germany, presented results of a study on Monday at the European Heart Rhythm Association (EHRA) Eurospace Cardiostim. “Pacemakers can mistakenly detect electromagnetic interference (EMI) from smartphones as a cardiac signal, causing them to briefly stop working. This leads to a pause in the cardiac rhythm of the pacing dependent … [Read more...]
Military Radio Frequencies May Interfere with Garage Door Openers
Remote-control garage door openers near the Blue Grass Army Depot in Richmond K.Y. may stop working due to military radio systems switching to a new frequency range. The U.S. military will switch all land mobile radios (LMRs) to new frequencies, which are also the same frequencies used by certain unlicensed consumer devices, like garage door openers. These frequencies have … [Read more...]
