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...]

New Waveguide Detectors Cover Frequency Ranges from 26.5 to 110 GHz
Pasternack introduces new high performance waveguide detectors that cover frequency ranges from 26.5 to 110 GHz. The detectors are zero biased and perform the best in KA, Q, U, V, E and W frequency bands. Because the detectors are zero biased, no external DC bias or mechanical tuning is needed. The detectors also offer a rugged steel construction, high thermal stability, … [Read more...]
New Bill in Romania to Allow Telecom Operators to Pay Less if Radio Interference Occurs
Romania’s Ministry of Communications has proposed a bill that will allow telecommunication operators to pay less to use radio frequencies if the frequencies are interfered by other radio stations. Radio interference from other radio communication stations can greatly affect the telecom operator’s work. The Ministry released the draft of the bill while a disagreement between … [Read more...]
Sirens Fail to Function During Tornado Warning Due to Radio Interference
An outdoor warning system failed to function properly during a tornado warning in Hannibal, Missouri on June 28 due to radio interference. Mike Hall, Marion County 911 director, is certain that the radio interference came from HPD traffic. “The city’s 16-siren system is activated through a single radio transmission. A day after the storm, Hall reported a review of the 911 … [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...]
