Cosmic spider shows clear signs of active star formation

Captured by the Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS), the Spider Nebula cuts a ghostly green figure in a new image release from NASA. The composite was captured in infrared light, a spectrum ordinarily invisible to the naked eye, though in this case common colors have been assigned to the different wavelengths allowing us to view the scene unaided.Read More

Hubble zooms in on galactic core

A new Hubble image has presented a stunning glimpse of the nuclear star cluster known to shroud Sagittarius A* (Sgr A*) – the supermassive black hole that lurks at the heart of our galaxy. The spectacular 50 light-year wide image was captured in the infrared spectrum by Hubble's Wide Field Camera 3.Read More

Infrared Sentry drone stays hot on the trail of missing hikers

With the ability to scan areas beyond the reach of human eyes, camera-equipped drones are emerging as a valuable tool for rescue efforts of all kinds. Now one startup is tuning the technology to the rugged Canadian wilderness, launching a portable drone that can be quickly unpacked and unleashed to capture thermal images and sniff out hikers that have wandered off course.Read More

High-tech camera allows us to see invisible methane gas

Although methane is one of the most potent of the greenhouses gases, scientists still aren't entirely clear on all of its ground-based sources. That's why researchers from Sweden's Linköping and Stockholm universities have created a camera that's capable of imaging methane in real time. They say that it could find use in monitoring sources such as sludge deposits, combustion processes, farms and lakes.Read More

Astronomers discover massive galaxy cluster 8.5 billion light-years from Earth

Astronomers have discovered a massive galaxy cluster located an impressive 8.5 billion light-years from Earth. It is hoped that further analysis of the cluster, which has been imaginatively named Massive Overdense Object (MOO) J1142+1527 (MOO J1142+1527), will allow scientists to shed some light on the evolution of some of the largest structures in our Universe.Read More

ESO's VISTA telescope spies hidden Milky Way component

An international team of astronomers has discovered a previously unknown component of the Milky Way – a thin disk of variable stars hidden in the galactic bulge. The observations, made using the ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA) telescope conflict with current theories regarding the composition of the center of our galaxy.Read More

DIY mouse trap sends photo alert when critter is caught

Humane mouse traps come in all shapes and sizes, but the aim of the game is the same – catch the pesky rodents that are munching through your breakfast cereal and evict them from the premises. For the most part, electronics don't feature. The RaspiTrap from tinkerer Alain Mauer is a little different. With the help of a slice of Raspberry Pi, a splash of IR sensor flavoring and some Wi-Fi magic, it sends a photo notification when the door closes behind a new prisoner.Read More

Density sensor lets you avoid the rush at your favorite haunts

If you've ever been on your sofa and wondered how long you might have to queue for a bike at the gym or how long the wait is for a table at your favorite restaurant, then the Density sensor could provide the answer. Designed to be attached to the entrance of a premises, the sensor captures people's comings and goings to provide real-time and historical data about the volume of traffic passing through.Read More

Herschel images present a stunning insight into the distribution of matter in our galaxy

Three stunning new images from ESA's Herschel Space Observatory are providing new insights into how matter is distributed in our galaxy. Observations made by the orbital telescope have led astronomers to conclude that our galaxy is threaded with filamentary structures similar to those featured in the newly-released images, the smallest of which stretches across 170 light years of space.Read More

New invention expands Wi-Fi bandwidth tenfold

The vast range of Wi-Fi-enabled devices available today means that anyone could have several personal electronic devices all trying to connect to a network simultaneously. Multiply this by many hundreds of people in a busy public place with Wi-Fi connectivity and this often means that available bandwidth is greatly reduced. To help address this problem, researchers at Oregon State University claim to have invented a new system called WiFO that incorporates infrared LEDs to boost the available Wi-Fi bandwidth by as much as ten times.Read More
