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...]
High-security Connectors Offer Industry Low VSWR, Insertion Loss and RF Leakage
Southwest Microwave, Inc., launches a new range of durable and rugged high-security SMKey Keyed Coax Connectors. The connectors are available in 10 different keyed combinations; each combination is uniquely polarized and includes a non-keyed option. The coax connectors operate from 3.7 mm DC to 18 GHz and are ideal for use in critical connection applications when mated … [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...]
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...]
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...]
Connector Series Includes EMI Shielding
Mouser Electronics introduces the Amphenol Pegasus series of twist and lock ‘scoop-proof’ connectors with EMI shielding. “EMI shielding is provided by an electroless copper and nickel plate, and a copper alloy spring finger gasket. Tests show greater than 50db of attenuation for low-end signals (<100Mhz) and greater than 40db of attenuation for high-end signals (<1Ghz),” … [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...]
