Stephen Hawking Project Questions Why Earth has No Communication with Extraterrestrial Life
Stephen Hawking recently discussed his new 100 million dollar project aimed at discovering extraterrestrial life (aliens), titled “Breakthrough Listen.” Frank Drake, chairman emeritus of the Search for Extraterrestrial Intelligence Institute, produced an equation in 1961 for calculating the amount of alien civilizations capable of communication with humans. When Drake plugs … [Read more...]
Study Reveals Radiation from Solar Events Unlikely to Affect Earth
“In recent years, research has suggested congenital birth defects down on Earth's surface could be caused by these ‘solar particle events’ - spikes in cosmic rays from the sun that touch off the northern lights and sometimes hamper communications or the electric power grid,” according to Science Daily. Even though airplane crews at high altitudes are exposed to harmful levels … [Read more...]
NASA Captures Four-hour Solar Flare on Video
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...]

Microwave Vision Group (MVG) announces the success of its new RF safety device, the EME Guard XS. The EME Guard XS is a small, portable, robust, user-friendly, and economically manufactured RF safety tool that offers high reliability. The device alerts people working near antennas to excessive EMF exposure levels. The device is best suited for people working near antennas, … [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...]
Spaceship Antenna to Prevent Communication Blackouts
A team of scientists from the Harbin Institute of Technology proposed a new spaceship antenna to prevent space communication blackouts. The group’s research has been published in the Journal of Applied Physics. The new antenna can prevent communication blackouts in space when spacecraft are coming back into Earth’s atmosphere. “The proposed technique can maintain … [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...]
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...]
