Astronomers have puzzled over why some extremely faint dwarf galaxies spotted in our Milky Way galaxy's backyard contain so few stars. The galaxies are thought to be some of the tiniest, oldest, and most pristine galaxies in the Universe. They have been discovered over the past decade by astronomers using automated computer techniques to search through the images of the Sloan Digital Sky Survey.
I recently read a report that the Department of Defense received over 80,000 counterfeit components from a now-defunct Shenzhen-based broker named "Hong Dark Electronics." After reading this, I felt two things: amusement and terror. I felt amusement that the DoD has been authorizing purchases from a Shenzhen-based broker (and in turn receiving various types of counterfeit components)...
W. L. Gore & Associates has developed new cable-based antennas (often referred to as leaky lines or leaky feeders) that improve signal propagation without increasing the amount of hardware required on an airplane. Ideal for both wide-body and single-aisle passenger aircraft, GORE Cable-Based Antennas provide reliable access to different wireless protocols so passengers can easily connect to in-flight entertainment, Internet servers, and email accounts
Teseq has introduced a new magnetic field coil that generates fields up to 1200 A/m during magnetic field testing.
ICP DAS USA, Inc. introduced I-7540D-WF, its CAN to Wi-Fi Converter, which will allow CAN bus devices to communicate with other CAN bus devices over wireless Wi-Fi networks.
An advanced telescope imaging system that started taking data last month is the first of its kind capable of spotting planets orbiting suns outside of our solar system. The collaborative set of high-tech instrumentation and software, called Project 1640, is now operating on the Hale telescope at the Palomar Observatory in California after more than six years of development by researchers and engineers at the American Museum of Natural History, the California Institute of Technology, and the Jet Propulsion Laboratory (JPL). The project's first images demonstrating a new technique that creates extremely precise "dark holes" around stars of interest were presented today at the International Society for Optics and Photonics (SPIE) Astronomical Telescopes and Instrumentation meeting in Amsterdam by Ben R. Oppenheimer, an associate curator in the Museum's Department of Astrophysics and principal investigator for Project 1640.
Polonium first hit the headlines when it was used to kill KGB agent-turned-Kremlin critic Alexander Litvinenko in London in 2006. This week, Yasser Arafat's widow has called for the late Palestinian leader's body to be exhumed after scientists in Switzerland found elevated traces of radioactive polonium-210 on clothing he allegedly wore before his death in 2004.
Using combined data from a trio of orbiting X-ray telescopes, including NASA's Chandra X-ray Observatory and the Japan-led Suzaku satellite, astronomers have obtained a rare glimpse of the powerful phenomena that accompany a still-forming star. A new study based on these observations indicates that intense magnetic fields drive torrents of gas into the stellar surface, where they heat large areas to millions of degrees. X-rays emitted by these hot spots betray the newborn star's rapid rotation.
In a cosmic case of "now-you-see-it, now-you-don't," a brilliant disk of dust around a Sun-like star has suddenly vanished, and the scientists who observed the disappearance aren't sure about what happened.
WASHINGTON (AP) -- Is it just freakish weather or something more? Climate scientists suggest that if you want a glimpse of some of the worst of global warming, take a look at U.S. weather in recent weeks.
Scientists working at the world's biggest atom smasher near Geneva have announced the discovery of a new subatomic particle that looks remarkably like the long-sought Higgs boson. Sometimes called the "God particle" because its existence is fundamental to the creation of the universe, the hunt for the Higgs involved thousands of scientists from all over the world.
A trade group has written the first "Code of Conduct" related to unmanned aerial vehicles. The Association for Unmanned Vehicle Systems International (AUVSI), which boasts more than 7,000 members across 60 countries, released its treatise in response to growing privacy concerns toward domestic UAV usage.
On July 5, NASA will launch a mission called the Solar Ultraviolet Magnetograph Investigation or SUMI, to study the intricate, constantly changing magnetic fields on the sun in a hard-to-observe area of the sun's low atmosphere called the chromosphere. Magnetic fields, and the intense magnetic energy they help marshal, lie at the heart of how the sun can create huge explosions of light such as solar flares and eruptions of particles such as coronal mass ejections (CMEs).
Producing strong, lightweight and complex parts for car manufacturing and the aerospace industry is set to become cheaper and more accurate thanks to a new technique developed by engineers from the University of Exeter. The research team has developed a new method for making three-dimensional aluminium composite parts by mixing a combination of relatively inexpensive powders.
Airbus's planned aircraft assembly plant in Alabama will cost $600 million to build and will employ 1,000 people when it reaches full production, officials said ahead of a formal announcement Monday.
NASA's Marshall Space Flight Center in Huntsville, Ala. is leading an international effort to develop and launch the High Resolution Coronal Imager, or Hi-C, on a sounding rocket from the White Sands Missile Range at White Sands, N.M. Hi-C is a next-generation suborbital space telescope designed to capture the highest-resolution images ever taken of the million-degree solar corona.
A Soyuz space capsule carrying a three-man multinational crew touched down safely Sunday on the southern steppes of Kazakhstan, bringing an end to their 193-day mission to the International Space Station.
A Russian Soyuz capsule landed on the Kazakh steppes on Sunday, safely delivering a trio of astronauts who helped to dock the first privately owned spacecraft during a six-month stint on the International Space Station.
WAGO Corporation’s DIN-rail mount 288 Series Signal Noise Filter removes disturbances from incoming power for industrial control panels. The 288-2003 pairs a 10A/120VAC Receptacle, common mode choke and WAGO 740 Series PCB Terminal Blocks on a 1.75’’ wide open assembly. Initially developed as a custom product by WAGO’s Engineering Services division for aquatic show control systems (dancing water fountains), 288 Series is now a standard product.
Curtiss-Wright Controls Defense Solutions (CWCDS) announced what is said to be the industry’s first rugged Air Flow Through (AFT) cooled GPGPU embedded DSP module. The announcement of the AFT version of CWCDS’ VPX6-490 GPU Application Accelerator, a dual NVIDIA GPU-based 6U VPX module
The world is about to get a well-earned long weekend but don't make big plans because it will only last an extra second.
Scientists in the United States have developed a paint that can store and deliver electrical power just like a battery.
An international team of astronomers have discovered evidence that our Milky Way had an encounter with a small galaxy or massive dark matter structure perhaps as recently as 100 million years ago, and as a result of that encounter it is still ringing like a bell. The discovery is based on observations of 300,000 nearby Milky Way stars by the Sloan Digital Sky Survey (SDSS).
Millions of smartphone users will soon begin receiving text messages about severe weather from a sophisticated government system that can send a blanket warning to mobile devices in the path of a dangerous storm.
Cole Hersee, the Commercial Vehicle Products division of Littelfuse, Inc., announced that it is introducing the latest product in the 95060 series of sealed rotary switches. This new, weather-sealed reversing switch, constructed with engineering thermoplastic, stands up to corrosion much better than older, metal models with similar functionality.
